Though remaining the same length, the new GS has a 10mm shorter front overhang, a 10mm longer rear overhang and is 30mm higher than its predecessor. Improving high speed stability, the front track has been increased by 40mm and the rear track by 50mm. Overall vehicle width has increased by 20mm. Key to the new design is a more aggressive frontal treatment which gives the new GS the powerful, commanding road presence appropriate to a Lexus sports sedan. In a further evolution of a styling cue first developed on the CT 200h, the inverted trapezoid upper grille and slanted lower grille have been combined and integrated into a single element, bridging the bumper midsection to create a prominent ‘spindle’ shape. The brake cooling ducts at either side of the spindle grille combine a distinctive style with engineering functionality. This bold, elegant and highly individual grille treatment makes the GS instantly recognisable as a Lexus at first glance, and will be adopted throughout the brand to strengthen the Lexus family identity between model ranges. The grille is flanked by headlamp clusters clearly positioned on a higher plane than the grille itself. This is a unique characteristic of Lexus models, focusing the eye at the very apex of the vehicle to give the design a resolute look and strengthen the impression of speed and agility. 7 The headlamps themselves are underscored by newly developed, integral LED Daytime Running Lights (DRL) which form the L-finesse arrowhead motif, further reinforcing the unique visual signature of the new GS. Exclusive to the hybrid GS 450h, a unique three-lamp design aligns the turn signal and Lexus-first high and low beam LED lamps in a single horizontal row. The improved illumination and beam range provided by LED lamps offers significantly superior visibility even under low beam driving conditions. Integrating sharply sculpted front foglamp housings, the deep front bumper forms a wide, trapezoid shape which anchors muscular front wings and flared wheel arches, reinforcing the new GS’s wider front track, broad stance and powerful road presence. In profile, the new GS shares its predecessor’s long, elegant cabin proportions and slingshot window design highlighted by a stainless steel door frame moulding. But a new, 15mm higher roofline reflects the increase in rear passenger accommodation and boot space whilst providing optimum aerodynamic performance for a drag coefficient of Cd 0.26. The door handle design has been changed, making it easier to grip, and the smart entry lock mechanism has been changed from a push switch to a touch sensor, improving both appearance and operability. The door 8 mirror now incorporates both an LED side turn signal lamp and a puddle lamp. Both the door panel gaps and the gap between wheel arches and tyres have been reduced, further enhancing the appearance of the new GS model range. To the rear, the new design narrows behind the flared wheel arches, exposing the lower portion of the rear tyre to emphasise the vehicle’s wide rear track. LED lamp clusters feature aero-stabilising fins to enhance the aerodynamic efficiency and driving stability of the car. Uniquely, the rear bumper of the GS 450h covers the exhaust pipe apertures. In addition to its new headlamp design, the new GS 450h may be further identified by hybrid-specific, front, rear and side blue badging. F SPORT Exclusive Features The F SPORT package is available across the entire GS model range. F SPORT exterior design features include exclusive front grille and bumper, rear bumper and lip spoiler treatment, 19” alloys and gradespecific badging. The F SPORT front bumper design features a more three-dimensional form at the sides, incorporating enlarged side grilles. Combined with an exclusive, upper and lower grille mesh design, this reinforces the new GS’s more aggressive appearance, wider track and sporting stance. 9 To the rear, F SPORT petrol engine models feature a grey metallic paint finish to the bumper diffuser. The GS 450h F SPORT diffuser combines grey metallic paint with a chrome plated moulding to the lower section of the bumper to further enhance the vehicle’s road presence. INTERIOR DESIGN All F SPORT models further benefit from a grade-specific rear spoiler and exclusive, dark premium metallic 19” alloy wheels. The new GS interior represents a continuation of the next generation Lexus interior design theme first seen in the CT 200h. With all functional driving components consolidated in the driver’s seat surroundings, it combines outstanding ergonomics with advanced Human Machine Interface technologies. Exterior Colours The new GS is available in a choice of 11 colours, including three that are new to the Lexus colour palette: Crimson Red, Meteor Blue and Sonic Silver. Vehicles in Crimson Red benefit from glass flakes incorporated into the coating, adding a high level of brilliance to the paint. Lexus engineers developed a new advanced coating process for the Sonic Silver finish. The new GS is the first Lexus to adopt this new coating technology. Vehicles with the Sonic Silver exterior appear more radiant as an additional metallic texture gives both strong shading and defined, sharp highlights. This metallic effect makes subtle and defined bodylines more noticeable and the surface appear finely polished. 10 An ergonomically designed, driver-focused cockpit enabling customers to remain alert and comfortable over long periods of time is an essential requirement of a sports sedan. Driver Focused Cockpit A clean, elegant dashboard design forms a wide horizontal plane, emphasising the overall roominess of the interior, whilst the door and centre console trim support the driver and front passenger in a secure, cocooned environment. The dashboard is divided into two distinct zones: an upper Display Zone, with the largest, ultra-wide, 12.3 inch, LCD multi-display screen yet installed in a production car, located at an ideal distance for at-a-glance viewing, and a lower Operation Zone, which allows access to system controls such as the second generation of Lexus’ award winning, computer mouse-style Remote Touch Interface (RTI). 11 Every aspect of the driving position has been carefully considered to create the ideal placement of controls, maximise comfort and minimise driver distraction and fatigue Brake pedal operability has been optimised with a new pedal shape and surface angle, and the footrest size increased to 300mm for a better fit and greater comfort. A new front seat features a lower hip point, placing the driver closer to the GS’s centre of gravity, and combines optimum holding ability with superlative comfort. An extended seat sliding range caters for the widest possible cross-section of occupants. As well as a new mid seat back folding adjustment, multiple adjustment mechanisms include a butterfly headrest, shoulder support, side support, 4-way lumbar support, and a cushion length adjustable by 76mm . The driver’s instrument binnacle incorporates large diameter Optitron dials. Minimising the driver’s eye movement from the road ahead, a new Head-Up Display (HUD) relays essential driving information. Its visibility has now been significantly improved. By implementing a wedge-shaped glass for the windshield and the PVC film for displaying information, the clarity of projection has been increased as well as double image projection avoided. The HUD now displays a wider range of information including SPORT mode (tachometer) display and ECO bar display in addition to the speed and audio displays already implemented. The airflow volume of the seat ventilation system has been increased to almost twice that of the current model. And soft padded, tactile finishes to the centre console arm rest, knee pads and door arm rests further enhance the long-distance comfort of the driving position. The steering wheel features an enlarged, 50mm telescopic reach to bring it closer to the driver, and has been set at a low angle to facilitate large steering inputs without the need for the driver to move their body unnecessarily through over-reaching. Even the cross-section has been painstakingly analysed; no longer uniform throughout the entire circumference of the wheel, its varying profile allows for a relaxing grip and smooth steering inputs. 12 The driver’s forward visibility has also been maximised – slim A pillars and a taller windscreen creating a wider field of view. And even the bonnet visibility range has been tailored to allow the driver to readily establish the vehicle extremities, making it easier to place when manoeuvring in confined spaces. Comfort, Convenience and Contemporary Craftsmanship Despite having an identical wheelbase length to that of its predecessor, the new GS offers increased space and comfort to all vehicle occupants. Both front and rear door openings have been designed for maximum ease of ingress and egress, with a particular focus on head clearance. Front cabin occupants benefit from a new seat back design which is more comfortable for taller passengers. A greater seat sliding range and seat height adjustment give an increase in legroom and up to 30mm of extra headroom. Rear seat passengers benefit from new seats with a revised seat back angle and redesigned cushion shape for greater comfort. A thin front seat design improves knee room by 20mm, and headroom has been increased by 25mm. Allied to a new, more compact rear suspension layout, a wider opening, increased deck length and reduced deck height combine to make the new GS’s luggage space more practical, and significantly increase its volume to up to 566 litres2 (a 31% increase over the current GS 350). The smartpackaging of the hybrid battery into a stacked format also increased the GS 450h’s luggage capacity to up to 482 litres2 (a 61% increase over the current GS 450h). Throughout the interior, high-quality materials and finishes convey a contemporary, premium look and feel, with a level of craftsmanship and attention to detail for which Lexus is globally renowned. 2 Boot space with tyre repair kit 13 A new interior colour scheme replaces the traditional two-tone design with a more versatile palette. The dashboard, floor and steering wheel are uniformly black to create a sporting, luxurious feel. And the leather instrument panel features coloured stitching - available in grey and ivory depending on the interior tone- to enhance the premium quality of the cabin environment. This beautifully crafted interior is complimented by an all-white LED interior lighting system which creates an atmosphere appropriate to a premium performance sedan. Reinforcing the GS’s highly refined onboard ambience, elements of the LED lighting illuminate to greet the occupants as they approach the car, even before it is unlocked, activating and fading thereafter in sequence with the vehicle starting procedure. Matching seat and door upholstery will be available in a choice of six colours - Black, Ivory, Grey, Saddle Tan, Topaz Brown and Garnet. In addition to Ebony, Walnut and Bamboo wood finishes, newly developed Black Gloss and Aluminium bring a contemporary, artistic look and feel to the interior ornamentation. F SPORT Exclusive Features F SPORT model interior design features include matching door and seat upholstery also available in Garnet -a grade-exclusive colour, combined with newly developed Aluminium ornamentation, 16-way electrically adjustable F SPORT front seats, a black headliner and pillar finish, a dimple perforated leather steering wheel and gear knob, Aluminium pedals and dashboard trim, exclusive black logo scuff plates and F SPORT badging to the steering wheel. A world first, the steering wheel of the GS 450h will be available in a real bamboo finish, symbolising the innovative spirit and environmental credentials of the vehicle’s Lexus Hybrid Drive system. INNOVATIVE ON-BOARD TECHNOLOGIES The GS interior’s air of sophistication and luxury is reinforced through Lexus’ painstaking attention to detail throughout. It incorporates exquisitely crafted details such as satin metal trim, high quality stitching and the brushed aluminium knobs of the audio system. A new analogue clock with LED indicators, carved from an ingot, adds a unique touch. 14 Several highly innovative technologies make a first appearance in the new GS model range, including a new, energy saving air-conditioning system with S-Flow and ‘nanoe’ technologies, a second generation Remote Touch Interface (RTI) linked to the world’s largest on-board multi-information display screen, and a choice of audio systems offering unparalleled power and clarity. Second Generation RTI with 12.3” Multimedia Display The second generation Lexus Remote Touch Interface (RTI) multi-function control device has been enhanced for increased user-friendliness and ease of operation. It now features the world’s first slide haptic joystick mechanism -a planar slide-type controller that is much like a computer mouse, and the ENTER command is now accomplished by simply pushing the controller. Usability has also been improved through the addition of ambient lighting, and by minimising the difference in height between the RTI controller and the armrest. RTI allows users to manipulate the cursor quickly and easily across the world’s largest on-board multimedia display; a 12.3 inch, full colour, LED screen with an ultra-wide, 24:9 format. The screen’s size allows for the permanent display of two types of information simultaneously, such as map/audio, night view/map and navigation input/incoming call. Improved Navigation System The new GS’ navigation system has been enhanced by using also TPEG (Transport Protocol Expert Group) data including TFP (Traffic Flow and Protection) information, parking lot availability and fees which additionally allows to set a certain parking slot as destination. S-Flow Air Conditioning with Nanoe Technology Considerably more powerful than the previous system, the new airconditioning features S-Flow technology to maintain optimum occupant comfort whilst significantly reducing power consumption. Using sensors it determines if the front passenger seat is occupied. If not, the system automatically closes all vents serving this seat. The same happens to the rear seats when the S-Flow button is switched on. This maximises system efficiency. In addition the system measures the ambient air temperature, interior air temperature and insolation to determine the optimal level of air conditioning. The target airflow volume is customised for each seat through Temperature Airflow Output (TAO) control. When the thermal load is large (cooldown in summertime, warm-up in winter) air conditioning is implemented in the entire car to quickly obtain a comfortable interior temperature. Once the overall interior temperature is stabilized, the system concentrates only on occupied seats. During the development of the centralised occupant sensing control system, intensive vehicle tests in wind tunnel facilities were performed. The system was also repeatedly tested on both test courses and actual roads to ensure it maintains comfortable driving in a range of environments. 15 In addition to the TAO control, upper and lower independent, multilayer air mix technology has been adopted to achieve an environment tailored for both driver, front and rear passengers. This allows for example to set the upper air mix for coolness to deal with effects of solar insolation, and at the same time the lower air mix for warmth. The new system also introduces a 2-tier Interior / Exterior Air Control which prevents window fogging by inducing low humidity exterior air to the upper half of the cabin while maintaining excellent heating performance in the foot area by circulating interior air. This avoids ventilation losses which are characteristic to conventional control system where cold exterior air is induced into heated interior air. The new GS is also equipped with a new deodorizing filter, which, in addition to the removal of pollen and dust, etc., also removes exhaust gas from the ambient air. In addition, the air conditioning system incorporates a new ‘nanoe’ technology system. This air cleaning technology operates automatically when the air conditioning is turned on. It releases 20 to 50Nm diameter nanoe particles -negatively charged ions wrapped in water moleculesinto the cabin via the driver’s side dashboard air vent. 16 By attaching themselves to airborne particles and molecules, the nanoe ions have been said to have both an air purifying and odour eliminating effect. They also deodorise vehicle seats and ceiling to create a cleaner cabin environment. In addition, because nanoe moisture content is approximately 1,000 times that of conventional ions, the emission of ions bonded to water molecules is said to have a moisturising effect on skin and hair, acting to enhance occupant well-being. Audio Systems The new GS range may be equipped with a choice of two audio systems. The standard system represents the next generation of realism and clarity in Lexus sound. It features a fully digital Class-D amplifier capable of creating virtually distortion-free sound with minimal voltage losses. The natural sound dynamics and rich harmonies generated by the high definition amplification are faithfully reproduced by an enhanced, 12-speaker layout which features a new, front three-way system. The new top of the range 17-speaker Mark Levinson® Premium Audio system creates sound based on the concepts of Effortless Dynamics and Effortless Transient Response, which combine natural dynamics with high response and tracking performance to offer sound quality equivalent to that of a live, concert hall performance. Using the same technologies as those found in top-end home audio systems, it features a newly developed, Generation III ML5 amplifier. Far outstripping the performance of the current GS sound system, the new amplifier generates 125 Watts per channel and a total of 835 Watts (75W and 505W more power respectively than the current system), whilst consuming just 6.5 Amps –less than a quarter of the power consumed by the current generation system. Developing twice the volume for the same power consumption, GreenEdgeTM power-saving technology has been incorporated into each of the 17 speakers. GreenEdgeTM technology covers a wider frequency band than conventional systems, giving an enhanced dynamic range. The new Mark Levinson® system features five, newly-developed, 90mm GreenEdgeTM Unity speakers with a coaxial structure which integrates mid- and high-range units within the same structure. The all-round cabin positioning of the five Unity speakers gives consistent timbre for both front and rear seat occupants, resulting in a whole new level of surround sound, definition, atmosphere and quality. 17 18 DRIVING DYNAMICS • Rigid bodyshell and new suspension for optimum agility and stability with superb ride comfort • Adaptive Variable Suspension (AVS) to further enhance ride quality, stability, body control and steering response • Powerful brakes for enhanced stopping power and control • Drive Mode Select function for a choice of ECO, NORMAL, SPORT S and SPORT S+ driving modes, and manual paddle shift override • GS 450h F SPORT also available with the Lexus Dynamic Handling system - an integrated four-wheel steering system for sharper response and greater agility • Lexus Dynamic Handling system - the world’s first hybrid vehicle integration of Dynamic Rear Steering (DRS), Variable Gear Ratio Steering (VGRS) and Electric Power Steering (EPS) The new GS has been designed to offer customers a much more engaging and pleasurable driving experience. It combines sharp, responsive steering and excellent body control with outstanding high speed stability and all the ride comfort expected from a Lexus performance sedan. The significant improvements to the next generation GS’s driving dynamics have been achieved on three levels: 1. A re-engineered bodyshell with a 14% increase in rigidity, new suspension to promote optimum agility and stability whilst maintaining ride comfort, and more powerful brakes for enhanced stopping power and control. 2. Adaptive Variable Suspension (AVS) to further enhance ride quality, stability, body control and steering response. 3. The Lexus Dynamic Handling system; leading edge platform technology which offers the world’s first integration of Dynamic Rear Steering (DRS), Variable Gear Ratio Steering (VGRS) and Electric Power Steering (EPS), to coordinate every aspect of front and rear wheel control and provide agile, sharp and confident driving behaviour with a more direct response to the driver’s actions. Body Rigidity Extensive computer aided design has been used to optimise body rigidity, ensuring precise vehicle movement in response to steering input. The next generation GS features new underbody, rear suspension member and front end module components. Increased spot or laser welding has improved rigidity to the door openings, rear under body and rear partition. Additional reinforcement or thicker gauge sheet metal has been employed in the cowl panel, front and rear underbody and rear partition. And the design of the front suspension member, rocker inner and dash panel has been made stronger. 19 In combination, these enhancements have increased bodyshell torsional rigidity by 14%, allowing the new GS to respond with much greater accuracy to the driver’s commands. Aerodynamics The new GS marks the introduction of a completely new approach to the management of airflow over the vehicle body – aerodynamic damping. The basic concept involves bringing the flow of air closer to the vehicle body, using it to help control the vehicle’s movement to enhance handling stability. Allied to smooth, flowing bodywork boasting exceptionally narrow panel gaps and minimal protrusions, the addition of numerous aerodynamic under-body elements and aero-stabilising fins further promotes vehicle stability and helps reduce wind noise to a minimum. Particular attention has been paid to rectification of the airflow along the vehicle sides to provide body movement damping. The smoothing of airflow in and around the front and rear wheel arches, and the reduction of air pressure within the wheel arch itself contribute to improved steering response, a flat ride and enhanced road holding. In addition, the rear lamp clusters feature aero-stabilising fins which generate a vortex to the rear of the vehicle, helping to improve handling stability. 20 Acting in combination, these elements give the new GS optimum aerodynamic performance, and a drag coefficient of only Cd 0.26. Suspension The new GS features a double wishbone front and multilink rear suspension system which combines legendary Lexus ride comfort with excellent agility, optimum steering feel and a particular focus on rear stability. The front, high-mount, double wishbone suspension set-up incorporates newly designed, unequal length upper and lower control arms in forged aluminium, to both reduce system weight and improve ride comfort. The Front double wishbone suspension rigidity of upper and lower arms, the hub bearing unit and the steering knuckle has been increased to enhance steering responsiveness. Caster trail has been increased to enhance straight line stability and steering feel. Optimising roll attitude, the stabiliser arm ratio has been improved, the stabiliser system spring rate increased, and the shock absorber rebound spring rate substantially increased. In addition, lower bushing has been enlarged to minimise the transmission of vibrations. To the rear, an advanced multilink set-up with toe control bars and an aluminium rear axle carrier has been completely redesigned. The spring and shock absorber have been separated to increase their efficiency and create a more compact design which improves the vehicle’s luggage capacity. Rear stability has been significantly improved through the addition of a rebound spring; increased stabiliser shock absorber arm ratios; the replacement of suspension ball joints with bush joints; the positioning of the toe control arm at the rear and the minimisation of toe change during the suspension stroke. In addition to greatly increasing rear stability, these components also combine to improve the new GS’s roll posture, ride comfort and straight line stability, whilst reducing harshness. Ride comfort has been further improved by the adoption of low-friction oil in both front and rear shock absorbers. Rear multilink suspension F SPORT Suspension F SPORT models feature retuned front and rear suspension to further enhance the efficiency of the Adaptive Variable Suspension (AVS) system, maximising body control and steering response for improved vehicle agility. Both front and rear shock absorber characteristics have been modified to optimise AVS damping control, and the adoption of low-viscosity oil reduces friction for improved shock absorber efficiency. In addition, the rear suspension shock absorber has been inclined further to the rear, and the lower bushing enlarged and stiffened. 21 In combination, these modifications maximise the AVS system’s control of body roll and, hence, improve the vehicle’s response to steering inputs for increased agility and a more engaging driving experience. Brakes Featuring 334 x 30mm ventilated discs to the front and 310 x 18mm solid discs to the rear, the GS’s braking system has been designed to offer drivers enhanced power and control, with improved pedal feel and a consistently fade-free performance. Simultaneously, tyre friction characteristics and ABS control have also been enhanced to minimise stopping distances. Brake booster power has been increased, and the pedal shape, angle and ratio changed to provide instant response to changes in applied pedal force and greater controllability. Brake cooling performance has also been improved through an increase in ducted cooling airflow volume, minimising brake fade even under protracted use. The GS 450h’s Electronically Controlled Braking (ECB) system characteristics have also been modified to provide greater responsiveness from the first touch of the pedal. All GS models fitted with the F SPORT package are equipped with larger, 356 x 30mm ventilated front discs. A world-first, the hat section of the two 22 piece rotor has been fabricated in aluminium to both reduce weight and suppress heat deformation. Adaptive Variable Suspension (AVS) system The Adaptive Variable Suspension (AVS) system allows the driver to fine tune the GS’s ride characteristics with a choice of two damper settings; ‘Normal’ mode, for everyday driving comfort, and ‘Sport S+’ mode, for improved body control and precise responses to steering input whilst cornering. In response to driving operation, vehicle body motion and road surface conditions, AVS automatically adjusts the performance of the suspension at Adaptive Variable Suspension all four wheels independently activates the adjustable damping force shock absorbers to fulfil a wide range of specific control functions. the airflow volume is lowered when in ‘high’. Additionally, the air-conditioning stays switched off until engine cooler water reaches 30.5°C. Selecting the AVS system’s ‘Sport S+’ mode automatically increases the difference between inner and outer shock absorber damping through corners to further reduce vehicle roll. Simultaneously, VGRS automatically reduces the steering gear ratio by approximately 10% whilst the Electric Power Steering (EPS) increases steering assist torque by some 4%. These measures combine to minimise body roll, sharpen vehicle handling and optimise steering feel for the ultimate in sports sedan driving. The ECO mode can be selected by turning the dial anti-clockwise. Once selected, the meters and the ‘ECO mode’ indicator are illuminated blue. In SPORT S mode the powertrain is adapted to increase acceleration response. In the petrol version this results from a shift timing change; in the hybrid version it is achieved through drive force and engine responsiveness enhancements in the partial and full throttle range respectively. SPORT S mode can be selected Drive Mode Select System The next generation GS features a Drive Mode Select function that allows the driver to choose between ECO, NORMAL, SPORT S and SPORT S+ driving modes, maximising either the vehicle’s environmental efficiency or its dynamic abilities. In ECO Drive Mode, engine power output, throttle opening and air conditioning are controlled automatically to maximise fuel economy. In addition to moderate drive force changes, the air conditioning functions are also adjusted, limiting ventilation losses. At temperatures below 10°C (for GS 450h) and 3°C (for petrol version) the seat heater switches on automatically. The air-conditioning changes to recirculation as from 20°C and 23 by turning the dial once clockwise. When selected the meter illumination turns red and the SPORT S mode is indicated on the 12.3’’ screen. Available on GS models equipped with the Adaptive Variable Suspension (AVS), SPORT S+ mode combines the SPORT S mode’s enhanced powertrain output with coordinated control of the Vehicle’s Dynamic Integrated Management (Step 5 VDIM) including Adaptive Variable Suspension (AVS) and Electric Power Steering (EPS). When equipped with Lexus Dynamic Handling (LDH), also Variable Gear Ratio Steering (VGRS) and Dynamic Rear Steering (DRS) are included. When M-range is selected, the driver benefits from the total control of fully manual gear changes via steering wheel mounted shift paddles. With rapid up shifting and throttle blipping on down shifts, customers can enjoy the most direct, sporting driving experience the new GS has to offer. Enhancing the enjoyment of the new GS’s expanded breadth of driving style preferences, the ambient illumination of the driver’s instruments changes to a tranquil blue in ECO mode, whilst switching to red in both SPORT S and SPORT S+ modes. Switching to SPORT S and SPORT S+ modes in the GS 450h automatically changes the system power indicator into a tachometer. All these enhance the new GS’ stability and steering rewarding the driver with the ultimate in sporting driving dynamics. The SPORT S+ mode can be selected by turning the dial twice clockwise illuminating the meters red and the SPORT S+ mode is indicated on the 12.3’’ screen. The Lexus Dynamic Handling (LDH) System The GS 450h F SPORT can be equipped with the Lexus Dynamic Handling system, making it the world’s first hybrid vehicle to feature an integrated fourwheel steering system. In addition, a new Sport-D Control system, activated when SPORT S and SPORT S+ modes are engaged, enhances the performance of the GS 350AWD’s automatic transmission. With the gear shift level in D-range, Sport-D Control automatically shifts down the appropriate gear when the vehicle approaches a corner and maintains the gear when cornering, making maximum acceleration available to the driver as he exits the bend. The leading edge platform technology of the Lexus Dynamic Handling system offers an integration of Dynamic Rear Steering (DRS), Variable Gear Ratio Steering (VGRS) and Electric Power Steering (EPS), to coordinate every aspect of front and rear wheel control and provide agile, sharp and confident driving behaviour with a more direct response to the driver’s actions. Monitoring vehicle speed, steering direction and driver inputs, LDH calculates the optimum angle for all four wheels. Using VGRS to the front and DRS 24 to the rear, the system can independently control both front and rear wheel steering angles to greatly improve turn-in response, rear grip, vehicle stability and overall agility when cornering. The LDH system monitors vehicle speed and yaw rate, steering angle and speed, and lateral G to calculate the required rear wheel steering input, to a maximum of 2.0 degrees. At most speeds below 80km/h the front and rear wheels turn in opposite directions. In certain conditions at speeds over 80km/h, front and rear wheels turn in the same direction. Further coordinating DRS with VGRS and EPS, the Lexus Dynamic Handling system will automatically customise the adaptive suspension tuning and active safety systems to suit road conditions, vehicle speed and driving style, giving customers the confidence to fully exploit the new GS’s exceptional driving performance.

GS 450h Reinforcing the company’s commitment to the future of full hybrid drive technology, the new GS 450h is equipped with a second generation Lexus Hybrid Drive system. Incorporating comprehensive improvements to every aspect of its full hybrid powertrain, the new GS 450h offers significant reductions in fuel consumption and CO2, NOx and PM emissions, with no loss of performance. 3 With a total system power output of 254kW/345DIN hp, the GS 450h will accelerate from 0-100km/h in 5.9 seconds and has a maximum speed of 250km/h. Conversely, fuel consumption has been reduced by 23% to 5.9l/100 km, and CO2 emissions have fallen to 137g/km. Lexus Hybrid Drive System Architecture As with every Lexus hybrid vehicle, the new GS 450h is a full hybrid capable of operating in petrol or electric modes alone, as well as a combination of both. Its Lexus Hybrid Drive system features an ultra-smooth running, 213kW/290DIN hp, 3.5 litre V6 petrol engine mated to a compact, highoutput, water-cooled permanent magnet electric motor, the two powerplants driving the rear wheels both independently and in tandem, as appropriate. In addition to the petrol engine and electric motor, the new GS 450h’s hybrid drive system further comprises a generator, a high-performance nickelmetal hydride battery, a power split device which, via planetary reduction gears, combines and re-allocates power from the engine, electric motor and generator according to operational requirements, and a compact power control unit to govern the high speed interaction of the system components. 3.5 Litre Atkinson cycle V6 Adapted specifically for the hybrid powertrain, the 3.5 litre, DOHC, V6 petrol engine benefits from several technical improvements. It adopts the Atkinson cycle to optimise the fuel-efficient benefits of Lexus Hybrid Drive. Not all European markets introduce all three powertrains. For more information please contact your national PR Manager 27 With conventional four-cycle petrol engines, there are times when ‘fuel enrichment’ becomes necessary, cooling exhaust gases to prevent degradation or destruction of the catalytic converters. Because the intake valves close late in an Atkinson cycle engine, compression is delayed. This creates a high expansion ratio for less compression, reducing intake and exhaust energy losses and converting combustion energy to engine power more effectively. As a result, the exhaust temperature is lower than that of conventional engines. Further reductions in fuel consumption have been achieved through a high physical compression ratio of 13:1, a new, mid-port intake tumble generator and the adoption of next generation D-4S direct injection technology. D-4S is the latest evolution of Lexus’ stoichiometric, 4-stroke, direct injection technology. With one injector installed in the combustion chamber and a second mounted in the intake port, it combines the strengths of both direct and port injection, realising optimum engine efficiency throughout the power band and improving torque across the rev range, whilst minimising fuel consumption and emissions. The new GS 450h’s next generation D-4S system features new slit-type injector nozzles with a modified port shape, a higher fuel pressure for more efficient combustion, and idle port injection for improved NHV characteristics. 28 Engine noise, vibration and friction has been lowered through the adoption of lightweight chain technology, a piston pin offset change and a reduction in the number of drive belt reinforcement ribs. In addition, engine durability has been improved through the removal of all external oil lines, and environmental performance enhanced by a newspecification catalyst which contains greatly reduced levels of precious metal. Additional Hybrid System Component Improvements The cooling performance of the hybrid system’s Power Control Unit (PCU) has been improved through the adoption of dual cooling paths and a singlepiece, integrated DC/DC converter. System control has been enhanced. The PCU boosts motor drive voltage to a maximum 650V in SPORT S mode and limiting it to a maximum of 500V in ECO mode to provide a more environmentally–friendly driving performance. The electric motor features lighter mounts and a reduction in friction. And the system’s regenerative braking operation range has been expanded, contribution to further improvements in fuel efficiency. In addition, the battery layout has been redesigned; a new stacked configuration maximising luggage space. GS 250 Expanding the powertrain line-up to offer further improvements in fuel economy and emissions, a 2.5 litre V6 petrol engine is available for the first time in the Lexus GS model range. The V6 features D-4S direct injection, and Dual VVT-i (Variable Valve Timing-intelligent) to both intake and exhaust camshafts, enhancing engine performance. It develops 154 kW/209 DIN hp at 6,400rpm and 253Nm of torque at 4,800rpm, accelerating the GS 250 from 0-100km/h in 8.6 seconds and giving a maximum speed of 230km/h. Fuel consumption is 8.9l/100 km, and CO2 emissions 207g/km. The new 2.5 litre V6 is mated to Lexus’ ‘6 Super ECT’ close-ratio 6-speed automatic transmission, which features a sequential manual shifting mode. As with the 3.5 litre engine, it incorporates numerous technologies including faster shift speeds, earlier torque converter lock-up and downshift throttle blips- to support the range of driving modes available through the Drive Mode Select system. 29 GS 350AWD The 3.5 litre V6 petrol engine of the new GS 350AWD has been revised to lower both fuel consumption and emissions. The advanced V6 features D-4S direct and port injection, and Dual VVT-i (Variable Valve Timing-intelligent) to both intake and exhaust camshafts, significantly enhancing engine performance and reducing fuel consumption. It develops 233 kW/317 DIN hp at 6,400rpm and 378Nm of torque at 4,800rpm, accelerating the GS 350AWD from 0-100km/h in 6.3 seconds and on to a maximum speed of 190km/h. Fuel consumption has been reduced to 10.2 l/100 km, and CO2 emissions are 237g/km. The ‘6 Super ECT’ close-ratio 6-speed automatic transmission features a sequential manual shifting mode. It incorporates numerous technologies including faster shift speeds, earlier torque converter lock-up and downshift throttle blips- to support the range of driving modes available through the Drive Mode Select system. The GS 350AWD’s electronically controlled all-wheel drive system is designed to improve traction and grip by automatically varying front-to-rear torque balance from 50:50 to as much as 20:80, providing exceptional stability under all driving conditions. 30 31 32 SAFETY • Advanced Pre-Crash Safety (PCS) system incorporating Driver Monitor Camera • Adaptive Cruise Control (ACC) system now functions at all speeds down to 0km/h • Step 5 Vehicle Dynamics Integrated Management (VDIM) integrating Lexus Dynamic Handling (LDH) system • Lane-Keep Assist (LKA) and Blind Spot Monitor (BSM) systems • Lexus Night View system • Head-Up Display (HUD) with an expanded content menu including tachometer information • Intelligent Adaptive Front-lighting (I-AFS) with Automatic High Beam • Enhanced Pedestrian Protection • 10 airbags and rear seatbelt pre-tensioners • Emergency Stop Signal Lamp The new Lexus GS is comprehensively equipped with the most technologically advanced pre-emptive, active and passive safety and driver assistance systems available on the market today. An Advanced Pre-Crash Safety (PCS) system incorporates a Driver Monitor Camera. PCS pre-emptively optimises front seat belt and emergency braking systems to help reduce collision damage and injury. A complementary Adaptive Cruise Control (ACC) system, now available on the GS 450h, functions at all speeds down to 0km/h. The GS features the latest, Step 5 generation of Lexus’ state-of-the-art Vehicle Dynamics Integrated Management (VDIM), which now integrates the newly developed Lexus Dynamic Handling (LDH) system. Additional active safety features include a Lane-Keep Assist (LKA) system, a Blind Spot Monitor (BSM) system, the Lexus Night View system, and a Head-Up Display (HUD) with an expanded content menu. The new Lexus benefits from no less than 10 airbags, and rear seatbelt pre-tensioners are fitted as standard. Intelligent Adaptive Front Lighting (I-AFS) enhances visibility through bends, whilst the new GS’s front bumper, cowl and corrugated sheet bonnet have been carefully designed to offer enhanced pedestrian protection in the event of a collision. PREVENTIVE SAFETY Advanced Pre-Crash Safety (PCS) The new GS is equipped with a sophisticated, Advanced Pre-Crash Safety (PCS) system that can help reduce collision damage and injury. The PCS system features a millimetre-wave radar sensor, operating within a 20 degree scanning radius to detect obstacles in front of the car, even during cornering. 33 Via numerous sensors, a pre-collision system computer monitors vehicle speed, steering angle and yaw rate inputs to help determine in advance whether an impending collision is unavoidable. If there is a high possibility of a collision, PCS will alert the driver via both a buzzer and a warning on the multi-information display, activate the Pre‑Crash Seatbelt pretensioners to retract all slack from the front belts and, when he begins to brake, provide Pre-Crash Brake Assist to supplement his own braking effort. In addition, PCS implements a close interaction between the Variable Gear Ratio Steering (VGRS) and Dynamic Rear Steering (DRS) incorporated within the GS’s Step 5 Vehicle Dynamics Integrated Management (VDIM) system, improving the vehicle’s response to the driver’s emergency steering inputs to increase the chances of avoiding the obstacle. If the driver does not brake and a collision is inevitable, Pre-Crash Brake will automatically apply the brakes to reduce impact speed. PCS has been revised in the new GS. The timing of brake intervention has been increased from 0.8 to 1.2 seconds before anticipated impact, both improving the chances of avoiding a frontal collision and, in the event of impact, lowering the collision speed by about 15km/h to greatly reduce vehicle damage. 34 Driver Monitor Camera The Advanced Pre-Crash Safety system also incorporates a Driver Monitor Camera. The system employs two near-infrared LEDs and a CCD camera built into the top of the steering column. Monitoring various aspects of the driver’s face including the degree of eye opening, the system is able to determine if the driver’s eyes are closed. If this is the case when there is a danger of collision, the timing of the Pre-Crash warning sequence is brought forward to alert the driver in good time. All-speed Adaptive Cruise Control (ACC) Complementary to the PCS system, the new GS features an Adaptive Cruise Control (ACC) system. The system offers two modes: constant speed control, and vehicle-to-vehicle distance control. Operational at speeds over 50km/h, the constant speed control functions in the manner of a conventional cruise control system. Capable of differentiating between vehicles directly ahead of the Lexus and those in an adjacent lane, the vehicle-to-vehicle distance control system employs the PCS millimetre-wave radar sensor, allied to constant speed, decelerator, follow-up and accelerator controls, to automatically slow the GS, match the speed of the vehicle in front and, once the road is clear ahead, accelerate to the previously selected cruising speed. Pre-Crash Safety Driver Monitor Camera ABS Traction Control 35 Exclusive to the GS 450h, ACC is now capable of operating at all speeds down to 0km/h. After a complete stop, and then restart of the preceding vehicle, the GS’s driver need only press the accelerator briefly to reactivate ACC’s tracking of the car in front. ACTIVE SAFETY Vehicle Dynamics Integrated Management (VDIM) Step 5 The new GS features the latest, Step 5 generation of Lexus’ state-of-theart Vehicle Dynamics Integrated Management (VDIM) system, to enhance performance, traction control and vehicle stability. With comprehensive status data provided by sensors throughout the vehicle, VDIM integrates the GS’s Electronically Controlled Brake (ECB) fourwheel independent braking, Anti-Lock Brakes (ABS), Electronic Brakeforce Distribution (EBD), Traction Control (TRC) and Vehicle Stability Control (VSC) active safety systems with the Electronic Power Steering (EPS), Variable Gear Ratio Steering (VGRS), Adaptive Variable Suspension (AVS) and –for the first time- Dynamic Rear Steering (DRS) systems. Whilst the current generation GS’s VDIM system can help restrain vehicle yaw and roll motion through control of the AVS and VGRS, the newly developed Step 5 incorporates the Lexus Dynamic Handling (LDH) system. This enables the VDIM system to control the steering angle of all four wheels, achieving the ideal slip angle to help govern the lateral motion of the 36 vehicle for added stability when, for instance, there is a risk of understeer or oversteer when cornering, or when braking on a road surface with differing levels of grip between the left and right wheels. By the application of integrated control of all the elements related to vehicle movement, including motor torque, brakes and steering, VDIM not only optimises the activation of braking, stability and traction control systems, but is also able to further improve the overall kinetic performance of the vehicle. Moreover, whereas conventional safety systems are only activated immediately after a limit of the vehicle’s performance envelope has been reached, VDIM activates control before that limit is realised. As a result, the limits of the vehicle’s performance threshold have been expanded, whilst offering smoother vehicle behaviour at this threshold through less obtrusive intervention and, hence, a more pleasurable drive. Lane-Keep Assist (LKA) system With lane marker detection provided by an on-board camera, the new GS is equipped with a Lane–Keep Assist (LKA) system to help keep the driver from drifting out of his lane. Now offering smoother steering corrections, the system calculates the steering torque input required based on the results of lane-marker detection, and automatically generates appropriate torque. Blind Spot Monitor (BSM) system The Blind Spot Monitor (BSM) system uses radar devices mounted on the corners of the rear bumper to detect overtaking vehicles in adjacent lanes. Blind Spot Monitor Operating if the GS’s speed is greater than 40km/h and the relative speed of the two vehicles is less than approximately 28km/h, the system activates a warning via an indicator lamp in the outer door mirror. If the turn signal indicators are operating at the time, the warning lamp will flash at a faster 4.0Hz frequency than the 1.7Hz of the turn signal lamps to alert the driver. Lexus Night View system The Lexus Night View system combines a windscreen head-mounted near-infrared camera and infrared LED lamps mounted within the headlight clusters with a Night View ECU to display an image of the road ahead on the GS’s 12.3” centre console display screen. Head-Up Display The system will operate at speeds of between 15 and 80km/h, displaying an area up to 200 metres in front of the vehicle. Head-Up Display (HUD) White readouts on the Head-Up Display project key GS driving data into the driver’s line of sight on the base of the windscreen, including vehicle speed, turn-by-turn navigation, audio, Adaptive Cruise Control and 37 Pre‑Crash Safety system status. For the first time on a Lexus, the display also now includes tachometer information. The HUD’s white readouts use high-intensity LEDs to provide ample clarity and visibility, and it is extremely easy to use. Pressing and releasing the HUD main switch turns it on and off cyclically. The display position can also be adjusted, as can light intensity, which may also be adjusted automatically to the ambient light. Adaptive Front-lighting System (AFS) with Automatic High Beam The new GS features an Adaptive Front-lighting System (AFS), which automatically swivels the headlamp beam, helping to illuminate a bend as the driver steers into it. The new system features a more advanced swivel control, increasing the swivel angle of one headlamp only at low speeds to enhance intersection visibility, whilst swivelling both beams at higher speeds for improved visibility and reduced glare for oncoming vehicles. Through the combination of AFS and Dynamic Rear Steering (DRS), swivel control has now been developed to monitor front and rear wheel steering angle difference, as well as vehicle speed. 38 The headlamps also feature an Automatic High Beam system. A camera located in the inner mirror detects light sources in front of the new GS -including the headlamps of oncoming vehicles, the tail lamps of a vehicle ahead and street lighting- and the system will automatically switch the high beams on and off accordingly, obviating the need for manual operation of the dimmer switch. Emergency Brake Signal The new GS features an Emergency Brake Signal system. Based on information from the acceleration sensor, wheel speed sensor and brake pedal switch, the system monitors vehicle status and the driver’s brake operation, automatically flashing the brake lamps during emergency braking. By adopting an LED light source, the response speed of the brake lamps has been significantly improved, alerting the driver behind as quickly as possible to help prevent rear-end collisions. Tyre Pressure Monitor (TPM) A Tyre Pressure Monitor (TPM) can detect a loss of pressure in one or more tyres. Notifying the driver via a dashboard mounted warning light, the system will highlight any tyres affected by low pressure, indicating the current pressure. PASSIVE SAFETY Body Structure Reflecting the stringent car-to-car impact compatibility standards unique to the Lexus marque, the new GS has been created with the express aim of achieving class-leading safety in full-frontal, offset, side-on and rear collisions. The comprehensive use of high- and ultra-high-tensile steel within the body structure optimally transfers and disperses impact load, minimising cabin deformation during a collision and maintaining space for the occupants. Particular attention has been paid to side impact protection, with ultra-hightensile steel adopted for rocker outer reinforcement, the rear door impact beam sheet thickness increased, and Lexus’ first use of hot press sheet steel in the construction of the B Pillar. During the die moulding of hot press steel, firing and quenching occur at the same time as pressing, both enabling the creation of profiles that would be difficult to form with cold sheet steel, and increasing the strength of the material itself. Pedestrian Protection The new GS’s front bumper, cowl and corrugated sheet bonnet have been carefully designed to offer enhanced pedestrian protection in the event of a collision. 39 The bead height and pitch of the corrugated bonnet design have been optimised with a new, thinner design. The frontal bonnet structure has been designed to easily deform on contact with a pedestrian’s upper legs, and a gap between the bonnet and the top of headlamps helps reduce the force of a head impact. Impact absorbing materials built into the front bumper help reduce the load applied to a pedestrian’s legs. And the front wings incorporate a new, head impact alleviating structure. Both the cowl panel area and cowl louvre adopt easily deformed structures with deformation controlled by the use of different sheet thicknesses. Airbags The Lexus GS benefits from 10 airbags; two-stage Dual Supplementary Restraint System (SRS) front airbags, both driver and front passenger knee airbags (the latter installed in the glove box door), front and rear side airbags, as well as both front and rear side curtain airbags. The advanced, Supplementary Restraint System controls variable-force front airbags for both driver and front passenger. Sensors determine the severity on an impact and, hence, the force with which the airbags are deployed. 40 Body structure 41 SPECIFICATIONS Dimensions & Weights Exterior dimensions Overall length Overall width Overall height (Kerb Weight) Whellbase Tread front Tread rear Overhang front (GVW) Overahang rear (KerbWeight) Overahang rear (GVW) Min. running ground clearance w/o axle Location of Min.
