<\/figure><\/div>\n\n\n\nWhy F? Fuji Speedway and Higashi Fuji Technical Centre at the foot of Mt. Fuji have been home to the develop-ment of the IS F. That\u2019s three good reasons. Perhaps a better one is \u2018finesse\u2019. Like every Lexus, the IS F has to conform to what are probably the most stringent standards in the motor industry, those of Lexus engineers and designers, before it was even considered for public consumption. <\/p>\n\n\n\n
To these\ndedicated individuals the challenge was to build a mould-breaking performance\ncar whilst embracing the traditional Lexus values of technological\nsophistication, advanced safety, leading-edge engineering and unparalleled\nrefinement. To take another step forward in Lexus\u2019continuous pursuit of\nperfection. <\/p>\n\n\n\n
INNOVATING F PERFORMANCE <\/h4>\n\n\n\n
The\nchallenge of creating the IS F lay in increasing the \u201cInstantaneous Sensory\u201d\nelements of driving. To combine core Lexus elements with the ultimate in\nbraking, acceleration and handling performance to form a unique drivers car, a\ngenuine all-round high performance car, equally at home on track days or\nweekend trips. <\/p>\n\n\n\n
In doing\nthis the IS F engineering team needed to redefine how the driver feels about,\nand responds to his car. The IS F chief engineer wanted to deliver an unbroken\nseries of sublime moments for every driver, resulting in a unique per-formance\nexperience, one that totally redefines motoring at every level of driving skill. No easy proposition. <\/p>\n\n\n\n
MILLISECOND RESPONSIVENESS <\/h4>\n\n\n\n
Achieving\nthe IS F chief engineer\u2019s ideals meant the develop-ment team rethinking every\nelement of conventional performance. They wanted a car that would arouse any\ndriver\u2019s emotions, one that could \u201ctalk\u201d to the driver, yet still deliver all\nthe finesse that people expect from Lexus. For dynamic refined power they chose\na compact 5-litre V8 engine. <\/p>\n\n\n\n
By\ncombining this with the world\u2019s fastest 8-speed Direct Sport Shift (DSS)\ntrans-mission that shifts gear in just 0.1 seconds, they delivered the kind of\ndirect response formerly only found in\nthe upper regions of motor sport. <\/p>\n\n\n\n
To contain\nthis power, braking and suspension techniques were taken from the racetrack and\nrefined for everyday use. Finally they added a new type of VDIM (Vehicle\nDynamic Integrated Management system), before letting loose some of the world\u2019s\nbest test and racing drivers to finalise the mix. <\/p>\n\n\n\n
SOUND CHARACTER <\/h4>\n\n\n\n
<\/p>\n\n\n\n

<\/figure><\/div>\n\n\n\nA civilised yet extremely powerful engine, one that delivers smooth urban driving yet fun circuit driving, has never been easy to achieve. With the IS F the choice of an extremely compact 5-litre V8 was the first step towards realising it. <\/p>\n\n\n\n
The IS F\nengineering team soon decided that one of the prerequisites was a to use a\ndualintake system, one which controlled both the inlet length and the number of\navailable inlet ports. This allows both the amount and quality of the mixture\nto be much more efficiently controlled and lays the foundations for both the\ngentle and powerful aspects of the IS F\nengine. <\/p>\n\n\n\n
The\noptimisation and harmonisation of Lexus D-4S* direct fuel injection system with\nthe VVT-iE** variable valve timing system also received detailed attention.\nThis not only delivers optimum power\/torque combinations, but is also of\nprimary importance in achieving the ultra low levels of emissions that have\nbecome expected of Lexus. <\/p>\n\n\n\n
Critical\ndriving perception rests on split second impressions, so to increase the sense\nof unity between the accelerator and engine, newly designed high flow intake\nports and a small capacity surge tank were adopted to improve efficiency. <\/p>\n\n\n\n
To maintain\nengine stability during rigorous circuit driving, a newly developed\nhead-scavenge oil pump and oil cooler were adopted. As a result, optimum\nlubri-cation and oil condition is main-tained even during high G-forces and\nhigh operating temperatures. All of these measures play a major part, not only\nin the immediacy of the engine response, but in the seemingly endless linear\nacceleration available. <\/p>\n\n\n\n
Another\nemotive area, the actual sound of the engine, received high priority with the\nIS F. The car\u2019s highly significant aural sound design falls into three distinct\ncategories. In the low and medium speed range, the V8 engine creates a strong\nexhaust sound, while maintaining overall tranquility. When the higher speeds\nare reached, the second intake port opens, and the engine sound changes\nsuddenly to an impressively powerful sound. \n<\/p>\n\n\n\n
As the\nengine approaches the maximum speed range, only the polished and pure\nmechanical sound of the engine can be heard, intensifying in synchronisation\nwith the engine speed. <\/p>\n\n\n\n
*D-4S is Direct Injection 4-Stroke\nSuperior <\/p>\n\n\n\n
** VVT-iE is Variable Valve Timing \u2013\nintelligent Electric (on intake) <\/p>\n\n\n\n
HEART AND RATIO <\/h4>\n\n\n\n
A special\nkind of power demands a special type of transmission. The IS F introduces the\nworld\u2019s first and fastest, production 8-speed Direct Sport Shift (DSS) gearbox.\n<\/p>\n\n\n\n
The new\n8-speed DSS transmission of the IS F offers all the benefits of manual gearshifting,\nbut with full automatic convenience. A revolutionary lock up mechanism allows\nthe engine\u2019s power to be directly relayed to the transmission in second through\neighth gear, giving it the ability to up-shift gears in just 0.1 seconds. That\nis faster than both dual-clutch and sequential manual gearbox technologies. It\nalso results in an immediate and direct shift feeling. <\/p>\n\n\n\n
With so\nmuch power to transmit, easy starting and shock-free changing were high on the\nlist of priorities. The lock up clutch mechanism helps facilitate both. Also a\nnew oil cooler and catch tank keeps the oil temperature and pressure optimal,\neven during intense circuit driving. <\/p>\n\n\n\n
And\nnaturally there is a \u201cskip-shift control\u201d, a manual override, available\nwhenever the car is in drive. This allows the driver to fingertip select any\nratio, adding the dimension of full manual control. All of this adds up to\ntechnology that pleases on the track or just takes care of those endless\ntraffic days with equal efficiency and satisfaction. <\/p>\n\n\n\n
ADAPTIVE CONTROL <\/h4>\n\n\n\n
With the IS\nF the Lexus engineering team created a car that redefines Lexus in terms of\nsporting handling, while still retaining the virtues that Lexus customers\nexpect. The coil and wishbone front suspension and multilink rear, coupled with\nelectronically controlled power steering provided the perfect basis. <\/p>\n\n\n\n
To refine\nthe suspension IS F engineers used a data gathering system more usually\nassociated with racing saloons to analyse the suspension behavior under every\ncondition. This led them to re-evaluate every aspect, even the bushings. The\nresult is a suspension system that fully complements the dynamic performance of\nthe car. <\/p>\n\n\n\n
Once this\nwas in place they began work on a new Sports VDIM (Vehicle Dynamics Integrated\nManagement) system. This controls every dynamic aspect of the car and again the\nIS F development team tested this under every conceivable performance\nsituation. The difference versus the acclaimed VDIM on other Lexus models is\nthat on the IS F it now features a Sports mode to stretch its dynamic\ncapabilities even further. For the most experienced drivers, it can even be\nswitched off completely. <\/p>\n\n\n\n
DRIVING CONFIDENCE <\/h4>\n\n\n\n
<\/p>\n\n\n\n

<\/figure><\/div>\n\n\n\nHaving attained maximum driver satis-fac-tion from the steering and suspen-sion would amount to nothing in creating ultimate driver confidence without re-evaluating the brakes. For this, 360mm ventilated and drilled, 6-piston front brakes and 345 mm 2-piston rear brakes were jointly developed together with Brembo. These deliver optimum braking performance and respond perfectly to mercilessly repeated demand under even the worst conditions. <\/p>\n\n\n\n
<\/p>\n\n\n\n
Forged, sculptured 19-inch alloy wheels developed jointly with BBS reduce unsprung weight to near full-race efficiency. Together with ultra-low profile tires developed with both Bridgestone and <\/p>\n\n\n\n
Michelin\nthey were essential in delivering the increased grip and flexibility, together\nwith the special smooth road manners of the IS F. <\/p>\n\n\n\n
In fact\nworking together with the advanced sport VDIM, the brakes, tires and wheels\nwere largely instrumental in the fact that Lexus test drivers could lap the\nFuji Motor Speedway faster with the VDIM in Sport mode than with the VDIM\nswitched off. Clear evidence that in Sport mode the VDIM works with, rather\nthan against, the skills of the driver to create real confidence. <\/p>\n\n\n\n
F-FORWARD <\/h4>\n\n\n\n
The Lexus\nIS F is a performance car that travels from 0-100 km\/h in under 4.9 seconds*,\nmaintaining linear acceleration to its governed maximum of 270 km\/h. Yet it\ndoes that without permanent damage to the eardrums or seating access designed\nonly for contortionists. <\/p>\n\n\n\n
Dynamically,\nthe IS F provides high safety standards without being obtrusively safe. The car\nhas been tested by world class racing professionals, who have helped refine\nevery aspect of the VDIM system, chassis and steering. <\/p>\n\n\n\n
Above all\nthe IS F is a Lexus. That means every aspect has superior quality and integrity\ndesigned and engineered in. It is a unique performance car, but it is also a\ntrue drivers car. <\/p>\n\n\n\n
