The new is300 SportCross demonstrates Lexus continued ability to create a spectacular new concept in luxury and performance car design. It introduces radical different styling, to combine the dynamic performance and handling of the is300 saloon with 5-door versatility and practicality. It has created a new model that builds on traditional Lexus values, yet has once again created a new segment in the marketplace. While sharing the powertrain and front-end architecture of the is300 saloon, the SportCross pays careful attention to structural rigidity and weight distribution, including the use of an aluminium tailgate, to ensure that it handles as well as the best sports saloons. Clever detailing enhances the exciting styling and the distinctive, nimble, cross-over silhouette. Clever interior design ensures that while having a rear profile similar to a sleek coup, the is300 SportCross can accommodate over 280 litres of luggage under its parcel cover with rear seats upright. A further 96 litres of space is available in additional storage boxes, while with seats folded items over 2.6m long can be carried. The cross-over concept behind the is300 SportCross creates a brand new proportion to the vehicle says Chief Engineer Katayama. This is no boring station wagon, nor a Liftback model as we have had in the past. The SportCross is a new generation vehicle; cool and individual. Our aim was to make the is300 SportCross as good to drive as the is200 and is300 Sedan says Mr Katayama. It has almost the same performance. Its handling sharpness and stability is almost identical, its acceleration is similar, as is the way that it brakes. The SportCross has the advantage of 5-door versatility, with folding seats and active space in the rear, compared with a sedan. SportCross has the sort of versatility that you might associate with a SUV, but SportCross isnt dull and heavy. It has the sort of refinement and comfort you would associate with a Lexus, but this is much more than a luxury sedan. It has fantastic driving comfort.

Further airflow enhancements include the rounding of the front bumper bottom and engine cover lip on the SportCross, which result in both smoother airflow and reduced drag. The new grille design fitted to all new IS models also features a dramatically reduced aperture to further control underbonnet airflow. While the grille itself remains the same size, 80% of its openings are now sealed to reduce turbulence and drag.
Interior architecture combines emotion and practicality The Lexus is300 SportCross interior styling reflects the distinctive style of the exterior. It is sporty but spacious. The aim of the development concept, known as Heat in Cool was to ensure the fun-to-drive feel, but driver and passengers alike will appreciate the seats comfort and the light and roomy cabin. In the SportCross, although the instrument panel, console and trim are shared with the Sedan, careful use of the cool metal materials as an accent in the rear have maintained a high performance feeling, while practical refinements add to functionality and top quality trim maintains the Lexus expectation of luxury. The rear seats are designed to fold in a 60/40% split to further enhance load carrying capacity. This allows up to three people to be carried while extending the length of the available load space to 1670mm. The front passenger seat back can also be folded forward, allowing it to be used as a table when parked and extending the available load length to an astonishing 2600mm. A flat deck board that creates an almost level area across the rear load compartment, luggage box and rear deck area, is available as an option. The board made of lightweight resin, can be aligned at two levels. At the upper level, the deck becomes fully flat; at the lower larger luggage can be stowed. To allow three passengers to be safely carried in the back of the SportCross, full lap and diagonal harness are provided for all passengers, with the centre seat belt retractor built into the roof, to allow for optimum convenience. When two rear seat passengers are being carried, a central armrest, similar to the sedan, can be deployed. Both the left and right side rear seats, like the sedan, comply with ISO-FIX child seat requirements. The aluminium rear door of the SportCross, in addition to aiding optimum weight distribution, also enhances the feel of a true luxury car. Weighing 5.6kg less than an equivalent steel hatch, the aluminium door contributes to significantly lower opening forces and a better feeling on closing.
World-Leading powertrain performance and refinement Important as styling and interior appointments, the truly dominant feature of any member of the IS series is the driving experience - and at its heart is the powertrain. "The 3-litre engine brings exceptional power to a car regarded as one of the best handling in its class" says Chief Engineer Katayama. "The is200 has been praised for its combination of engine response and refinement. The new models are an extension and a growth of that cars success." Extending the capacity of its classic DOHC, straight six, Variable Valve Timing - intelligent (VVT-i) engine from 2-litres to 3 for the is300, boosts power from 155 DIN hp to 214 DIN hp and maximum torque from 195 to 289Nm. Matched to the legendary IS chassis, the Lexus is300 SportCross emphatically regains for enthusiastic drivers, the feeling that the driver, not the electronics system, is in control. While the larger engine of the Lexus is300 SportCross increases the cars weight from 1390 to 1495kg, its horsepower is translated into significant performance gains. 0-100km/h acceleration is achieved in around 8 seconds, compared with 9.5 for the 2-litre car, yet the combined fuel consumption remains at a highly reasonable 11.2 l/100km. Equally important is the fact that thanks to the natural characteristics of the straight six and the VVT-i valve timing, the torque curve remains linear for all road driving conditions. More than 250Nm is available from 2,000 rpm to the rev limit of 6000 rpm, giving smooth linear acceleration through the gears and rapid throttle response for safe overtaking and maximum driver enjoyment. The is300 is an intelligent engine which ensures that a high level of performance is balanced by low emissions and low noise. ACIS (Acoustic Control Induction System) has been adopted to improve the engines performance in low to mid-speed ranges, while a long tail pipe construction, which effectively allows the exhaust to double back on itself inside the main muffler, reduces low frequency boom from the tailpipe. Driver control on the Lexus is300 is further enhanced by the use of a new 5-speed automatic transmission with an E-shift push-button gearchange system.

Precise steering, positive suspension and powerful brakes are all integral parts of the safety package. Standard equipment also includes pre-tensioned front seatbelts with force limiters, along with driver and front passenger SRS airbags, plus side curtain shield SRS airbags.
The IS300 SportCross in Europe From its launch, the Lexus is200 added a new dimension to the Lexus brand, it brought passion and emotion to the brand and was another innovative product which redefined the way people look at Lexus says Kirk Edmondson, Deputy General Manager of Lexus Division in Europe. The is300 SportCross is another example of the innovation which makes Lexus one of the most exciting brands in Europe. As with the original is, the rx300, the gs before, the ls430 last year and the flagship sc430 this year, SportCross is redefining its area of the marketplace and adding another new dimension to the family of models which makes up Lexus." The product is delivering says Edmondson. The cars have been accepted, awareness is gaining, we are now seeking something unique for the Lexus brand. Passion. Products like SportCross are not going the obvious way. Love it or hate it it is unique. The SportCross is everything the Lexus IS sedan is, but with more room says Edmondson. There is no compromise on driving capability. Traditionally when you create a wagon, torsional rigidity and hence handling, is compromised not with the SportCross!

Lexus gs430 / gs300 - a drivers car of the highest dimension
gs430 combines legendary Lexus refinement and muscular 4.3 litre, 32-valve, V8 engine with intelligent Variable Valve Timing (VVT-i) and 5-speed automatic transmission.
gs300 features straight six, 3-litre engine with (VVT-i) and E-shift, 5-speed automatic transmission with steering wheel-operated gear selection.
Safety features include ABS, Vehicle Stability Control, Brake Assist and SRS side curtain shield airbag system.
The Lexus gs430 and gs300 offer what is truly a drivers car of the highest dimension. The GS range combines compact, distinctive styling with outstanding driving dynamics and performance, along with the refinement and luxury for which the Lexus brand is renowned. The gs430 shares with gs300 the exciting styling which defines the dynamic high-performance saloon and both models also share some of the most sophisticated automotive technology currently available. The classical combination of front engine, rear wheel-drive chassis and the customary levels of Lexus refinement remain unchanged. However the enhanced powertrain of the Lexus gs430 raises the driving experience to new levels. The Lexus gs430 is powered by a 4.3-litre, V-8 engine also utilised in the Lexus ls430. The engine features 32 valves, VVT-i (Variable Valve Timing intelligent), ACIS (Acoustic Control Induction System) and ETCS-i (Electronic Throttle Control System - intelligent), developing 283 DIN hp (208 kW) at 5600rpm and a maximum torque of 417Nm at 3500 rpm. The Lexus gs300 is powered by a 3-litre, six cylinder engine utilising 24 valves, twin overhead camshafts and Electronic Throttle Control System (ETCS) to develop 219 DIN hp (161kW) at 5800rpm and a maximum torque of 294Nm at just 3800rpm. With potential top speed of 250km/h and a 0-100km/h acceleration time of just 6.3 seconds in the gs430 (230 km/h) and 8.2 seconds for gs300, it is sufficient to humble many sports cars, but the big difference is in the refinement and performance of both GS models at all engine speeds. Both models use Lexus engine management systems which are among the most sophisticated available, controlling fuel injection and ignition timing to thousands of a second. Combined with intelligent Variable Valve Timing (VVT-i), it gives remarkable efficiency, low exhaust emissions and low fuel consumption. It also ensures unrivalled tractability and smoothness. Both engines are complemented by a Super ECT (Electronically Controlled Transmission) 5 speed, intelligent automatic gearbox which can adapt its gear shift pattern to suit driving style and road conditions. The transmission is also linked to the computerised engine management system, to momentarily reduce torque for even smoother gear changes. A similar transmission is used on both gs430 and gs300 models, with slight changes in internal construction to suit the output characteristics of the different models.

The gs300 is also available with E-shift, which has transmission shift controls located on the steering wheel. With the floor shift lever engaged in the M position, this allows drivers to manually change gear without moving their hands from the steering wheel.
Sophisticated suspension for driving pleasure and safety Complementing the classical front-engine rear-wheel drive configuration for maximum driving pleasure, the carefully tuned double wishbone suspension system features anti-dive and anti-squat geometry to ensure the best balance of comfort and control, matched to speed-sensitive, rack and pinion power steering. Controllability is further enhanced by the use of low-pressure, nitrogen gas-filled shock absorbers and a thicker, reshaped front stabiliser bar. Driver control is enhanced by traction control, a multi-channel anti-lock braking system (ABS) for the cars 4-wheel disc brakes and Vehicle Stability Control (VSC) system. This innovative system monitors the vehicle's behaviour during cornering and maintains vehicle stability by using the cars ABS, traction control and other sensors to correct oversteer or understeer before it occurs. A further significant safety enhancement is the use of Brake Assist, which interprets a quick push of the brake pedal as emergency braking and supplements the braking power applied to maximise braking performance in conjunction with ABS.
Smoothly sculpted, sporting exterior A key feature of the Lexus GS range is the sporting stance created by its external styling. The profile is based on a simple geometric ellipse which is then given a functional aerodynamic treatment to create what the designers referred to as an "aero-ellipse" shape. This aero-ellipse theme recurs throughout the design and echoes are to be found in the tinted glass covering the headlamps, the rear light clusters and the window contours. Extensive use is made of high-tensile steel in the body structure to reduce weight and further enhance efficiency. The body was also carefully designed to maximise the size of impact-absorbing crumple zones in the front and rear as well as incorporating substantial side impact protection bars in the doors.
These enhance the safety offered by safety control of front and side airbags for the driver and front seat passenger and seatbelt pre-tensioners with forcelimiter. SRS side curtain shield airbags are now fitted as standard in all GS models. Housed in the front pillars and roof side sections, they inflate at the same time as the seat mounted SRS side airbags to cover the front side window area.

Lexus ls430 - redefines automotive perfection
ls430 excels in every area of legendary Lexus perfection with some of the most sophisticated automotive technology available.
4.3-litre, 32-valve, V8 engine with intelligent Variable Valve Timing (VVT-i) offers increased performance and ultra low emissions with similar fuel consumption.
Subtly larger, with quieter, more spacious and more stylish interior. Yet coefficient of drag (Cd) of 0.25, the lowest in class.
Redesigned suspension for greater stability, response and handling. Yet an even smoother quieter ride.
Greater range of options for more individuality, including worlds most exclusive car audio system.
With the introduction to Europe in 2000 of the all-new Lexus ls430, Lexus again redefined the automobile market's expectation of luxury cars. A decade previously, the first generation Lexus established new benchmarks for performance, quality, quiet ride and luxury content - and the model remained a world-leader. While retaining the presence of the original ls400, the new ls430 combines a more dynamic profile with increased efficiency. To increase interior room in the ls430, Lexus lengthened the wheelbase by 75 mm with an overall length of 5005 mm. The overall height was also raised to gain more interior space, yet painstaking attention to detail has allowed Lexus to achieve the impressive coefficient of drag (Cd) of 0.25.

Refining the art of high-performance The first-generation Lexus ls400 was the original whispering giant when it joined the premium luxury segment more than 10 years ago, offering unheard of levels of refinement, efficiency and quietness. The new quad-cam, 32 valve, 4.3-litre V8 in the ls430 develops 282 DIN hp (207kW) at 5600 rpm and 417Nm of torque at 3500 rpm. Mated to a computer-controlled 5-speed automatic transmission, it powers the Lexus flagship from 0-100 km/h in just 6.7 seconds. This prodigious output is developed, as a result of Lexus engine management systems which are among the most sophisticated available, controlling fuel injection and ignition timing to thousands of a second. Combined with intelligent Variable Valve Timing (VVT-i), the 4.3-litre V8 gives remarkable efficiency, low exhaust emissions and low fuel consumption. It also ensures unrivalled tractability and smoothness. VVT-i eliminates the traditional compromise between low-end torque and high-rpm horsepower by optimising valve overlap throughout the engine's speed range (not just at one or two set speeds). Also utilising ACIS (Acoustic Control Induction System) and ETCS-i (Electronic Throttle Control System intelligent), Lexus tuned the ls430 engine to produce more torque across a broad engine speed range, making the car feel more responsive under all driving conditions. The ls430 engine is complemented by a Super ECT (Electronically Controlled Transmission) 5-speed, intelligent automatic gearbox which can adapt its gear shift pattern to suit driving style and road conditions. The transmission is also linked to the computerised engine management system, to momentarily reduce torque for even less discernible gear changes.
Revised suspension gives smoother ride and better driving dynamics Improved packaging of the overall design gives a well-balanced front/rear weight distribution of 53/47% and a tighter turning radius of 5.2m for easier manoeuvring. New front and rear suspension systems are designed to offer an exceptionally flat ride and straight line stability under even the most adverse road conditions. The aluminium-intensive design utilises new bearings and a longer wheel stroke for better ride comfort and responsiveness, while the lower unsprung weight of the components additionally aids ride and handling. In addition, electronically modulated air suspension, is available as an option on the Lexus ls430. The system is the first in the world to utilise the non-linear H00 control method, to control the damping of the air suspension and realise world-leading stability and ride quality. It has been 11 years since the introduction of the first air suspension to a Lexus model. The system maintains vehicle ride height at a specified level regardless of the number of passengers or load level. The height can be raised 20mm higher than the normal position for unpaved roads and is automatically lowered at high speeds to improve stability and aerodynamic properties. This generates a reduction in the coefficient of drag (Cd) from 0.26 to 0.25, the lowest of any car in the segment.

The highest standards of interior style and content The large and comfortable interior space of the new Lexus ls430 has been designed to provide a special combination of ergonomics and emotion. The interior is designed for greater space, comfort and luxury, taking maximum advantage of the newly-developed packaging. High-quality wood-grain panelling, featuring walnut and birds-eye grain, is extensively used on panel trims and door cappings, with the choice of genuinely fine materials and the precise fit and finish emphasising Lexus craftsmanship. The sculpted trim flows into the dash, maintaining the feeling of integrity and quality, with instrument clusters carefully designed to complement the overall luxurious atmosphere. The Lexus ls430 maintains the traditional ergonomic layout of analogue-type instrumentation for ease of use, the optitron combination instrument panel located closer to the drivers line of sight and featuring LED figures and red LED indicator needles on a low-reflection, upwardly curved, smoked acrylic face. In addition to speedometer and tachometer, the larger multi-information display also includes items such as dual trip odometers, low fuel warning and remaining cruising range information.
All Lexus ls430s offer full leather trim as standard, with a further option of semi-aniline leather. This special leather, offered for the first time by Lexus, takes significantly longer in the milling process and is much softer than regular leather. Power adjustment, with pre-set memory functions are available as an option to tailor the rear compartment to suit individual postures. When the doors are opened, an auto-return function, returns the seats to the previous position. Further comfort can be provided by specifying the optional seat heater, or the massage function, which can gently soothe and vibro-massage rear seat passengers. The front seats feature power adjustment in all dimensions, with memory functions for instantly resetting favourite positions. The power tilt and slide mechanisms located in the seat cushions allow 240mm of fore and aft movement, while the drivers seat cushion can be adjusted in length by over 70mm for greater thigh support. Additional adjustments for the front seats include dual lumbar controls and the automatic adjustment of power headrests with seat sliding, to offer optimum comfort and protection. A further refinement is the option of Climate Control seats for the driver and front-seat passenger. This utilises seat-mounted blowers to direct cool air through the seat upholstery when specified by dashboard control. Alternatively, fast-acting heating elements beneath the upholstery can provide warmth on demand. The steering wheel also features controls for the audio system, which includes as standard, a LW/MW/FM radio data system, cassette and an in-dash, single-feed 6-disc CD changer, feeding a 7-speaker system (9-speaker system is optional). The new CD changer location allows for a larger dual glove box, and expanded interior storage includes compartments in the centre console and under the front seats. The Mark Levinson audio system features a 440W power amplifier and seven custom-designed Mark Levinson speakers, linked to an AM/FM radio system, cassette and CD player with 6-CD auto changer.

The Lexus ls430 features as standard one of the most sophisticated climate control systems ever fitted to a production vehicle, it features temperature and sun-sensing articulating air registers. If for example, sunlight is concentrated on one side of the car, the registers will automatically deliver more cooling air to that side. The climate control, along with car audio and navigation functions are controlled by a central multi-display, utilising a 7 inch-wide LCD (liquid crystal display) screen with an infra-red, touch-sensitive panel to offer improved ease of use. The Lexus Navigator, GPS satellite navigation system has been further enhanced from versions previously used in the ls400, by upgrading from the previous CD (compact disc) to DVD (digital versatile disc) storage. The DVD, which uses a smaller laser beam diameter is able to record and play back approximately 7.5 times the volume of data. This allows for example, the storage of the entire European road system on a single DVD, removing the need to change discs in the system for long-distance travel. The Lexus Navigator system can even highlight points of interest, search for a house number or find petrol stations, in addition to showing the cars exact position at any time on the dashboard screen and guiding its occupants with voice instructions to any destination of their choice.

w/o moon roof 1165 with moon roof

When the roof is down, it disappears totally into the rear bodywork, aided by the ingenious movement of the roof compartment door and a 4-sectional package tray. On the move with the roof down, the sc430 continues to maintain the customary standards of Lexus refinement and comfort, thanks to the use of computer generated wind-wrap analysis to carefully control the airflow around the passenger compartment. An air deflector placed between the rear seat headrests assists this and further ensures comfort during high-speed, roof-down cruising. In addition to the manufacturer's own wind tunnel, the Maibara wind tunnel also used for the development of the Shinkansen Bullet Train, was utilised because of its very low background noise which allowed Lexus to concentrate on the reduction of wind noise as much as possible. The sc430 also features one of the worlds most advanced climate control systems that allows occupants to enjoy more top-down driving time than conventional cabriolets. The system adjusts airflow and temperature automatically, differentiating between top-up and top-down driving needs. The airconditioning system features two new lap jets which ensures a perfect temperature at all times. For open cruising in low temeratures, the lap jets that are located on the centre console blow warm air into the lower section of the cabin, to keep the legs and laps of the occupants warm.
Superior styling From day one of the design of sc430, Mr Nakagawa attached equal importance to both the interior and exterior styling: Lexus designers from Europe and Japan worked together to create the design, inspired by a location renowned for high-end luxury the French Riviera. Products such as high-performance luxury yachts were closely scrutinised to gain insight into truly luxurious lifestyles, reflected in both the avant-garde exterior and the sophisticated interior styling of the sc430. Once the exterior design was completed, I asked my styling team to pay special attention to the interior said Nakagawa. When the top is down, the interior is highly visible so I wanted the luxurious and sporty theme to continue inside the car.
Designs using moulded plastics were rejected in favour of utilising natural forms and materials such as wood and leather. As with the exterior styling, the design team sought expertise from outside the automibile industry to learn more about traditional craftsmanship and techniques. This included spending time with the craftsmen at the famous Yamaha music instrument factory to learn more about their special timber moulding techniques, used in forming pianos, violins and guitars.

Active and passive safety The Lexus sc430 is further enhanced by a class leading combination of active and passive safety. At the front of the sc430, the unique headlamp design offers as standard, projector-style HID lamps with low beams. Careful development has allowed a 5 lux beam projection distance onto the road surface of over 100m. Since safety is paramount at Lexus, the new sc430 takes advantage of several advanced technologies. The cabriolet uses a braking system featuring foursensor, four-channel anti-brake system (ABS), Electronic Brakeforce Distribution (EBD), Traction Control, Vehicle Skid Control (VSC), Brake Assist and Tyre Pressure Warning System (TPWS). EBD monitors all four wheels during braking and varies brake pressure according to the load on each wheel. Brake Assist is designed to determine whether the driver is attempting emergency braking and, if the driver has not stepped hard enough on the brake pedal to maximise the stopping force, it supplements the applied braking power.
The VSC system monitors the vehicle's behaviour during cornering and maintains vehicle stability by using the cars ABS, traction control, linear G, yaw rate and steering sensors to correct oversteer or understeer before it occurs by limiting rear wheel spin and lightly applying differential braking on slippery surfaces. Passive safety is as comprehensively addressed as on every Lexus model. A combination of drivers airbag, a dual stage passenger seat airbag that selects the opening speed in function of the level of impact, front side airbags, front seat belt pretensioner and force limiters ensure the highest possible standards of occupant protection.
Minimising noise and vibration The biggest challenge for the engineers of any open-topped car is the minimisation of vibration and noise. It took exceptional levels of development to achieve Lexus standards of refinement in the sc430, with both roof up and roof down. The vibration was initially minimised by the provision of additional strength in the A-pillars and rocker. Strengthening gussets were designed to ensure the optimum rigidity at the joints between B-pillars and the upper and lower cross members at the rear of the cabin, as well an expanded rocker section to minimise body deformation. This high torsional rigidity is a significant contributor to the reduction of resonance in the 13hz range and was further dramatically enhanced by the provision of V-braces at the subframe mounting points. As a result of model analysis, the large attribution of subframe cushions was discovered. A reduction scuttle vibration was realised by a change from conventional mountings to hydraulic mountings. The engine mount is tuned in such a way that the engine acts as a dynamic damper. This significantly enhances the resonance performance of the Lexus sc430 in the 18hz range. Careful tuning of this mounting contributes to a significant reduction in roof header lateral vibration. The minimisation of higher frequency wind and road noise was also a priority, with the aim of achieving the same performance as a closed-body car in high-speed cruising on a motorway. Wind tunnel examinations using calculation and scale models were repeated right from the ideas stage of the design to achieve the highest levels of airflow management.

Power with efficiency and refinement The 3-litre, 4-cam, all aluminium offers an unrivalled combination of performance, efficiency and low emissions. The Lexus VVT-i (Variable Valve Timing-intelligent) engine optimises valve overlap throughout the engines rpm range to eliminate the traditional compromises between low-end torque and high-end horsepower. The result is an engine that develops a class-leading 201 DIN hp (148kW) and 283Nm of torque, yet continues to produce eighty percent of peak torque as low as 1200rpm for optimum pulling power and standing-start performance. At the same time the VVT-i system enhances fuel economy and reduces exhaust emissions so effectively that rx300 meets the toughest requirements without the need for performance-sapping devices such as exhaust gas recirculation, required by many other such vehicles.
The smoothness and refinement of the V6 engine is further enhanced by the use of the first-ever fully active engine control mount, which is controlled directly by each combustion stroke of the engine. A solenoid-controlled diaphragm creates pulses which are equal but opposite to the engines movements to counteract vibrations.
Sophisticated drivetrain and suspension Specifically designed to meet the needs of customers who are already used to the standards of refinement and performance set by Lexus sedans, the rx300 drivetrain and suspension systems are well in advance of traditional off-roaders in terms of driveability, comfort, efficiency and safety. The Lexus rx300 features a 4-speed electronically-controlled automatic transmission matched to a sophisticated 4-wheel drive system featuring a viscous limited-slip centre differential. This requires no activation by the driver in slippery conditions and automatically transfers torque when required to the wheels which have the most traction. The resulting levels of traction combined with the engines power characteristics mean that the rx300 is capable of meeting most on- and off-road tasks without the need for a seldom-used low-range transfer gearbox and its associated cost, weight and maintenance implications. The result is that rx300 has an excellent power to weight ratio, which gives on-road performance to rival some sports sedans with a 0 -100km/h acceleration time of just 9.2 seconds and an electronically governed maximum speed of 180 km/h. Matching the rx300s straight-line performance is its ride, handling and cornering ability. While the rx300 has the size and stance of a mid-sized sports utility vehicle, it is built on a passenger car-style unibody platform rather than the body-on-chassis design still used by many off-roaders. To improve on its class-leading performance, the rx300 has been comprehensively re-engineered to suit European driving styles and conditions, which involves higher sustained speeds, harder acceleration and later braking. The Toyota Motor Europe Technical Centre in Brussels was actively involved fine tuning the new model with new springs, dampers and stabiliser bars, along with a remapped power steering system to give levels of weighting, feedback and responsiveness more appropriate to European conditions.
