THE POWER OF A RACE-BUILT 5.0 V8
The entire top end of the engine was developed with race bred technology. Free breathing cylinder heads with large intake and exhaust ports ensure greater power output. Higher lift camshafts increase valve opening, and together with a larger diameter electronic throttle, allow the engine to gulp huge volumes of air.
PERFORMANCE THAT REALLY PUMPS
For durability, an oil scavenging pump (pure race bred technology) captures oil forced to one side of the engine by the high G-forces of fast cornering, and pumps it back into the sump.
LOWER WEIGHT, HIGHER REVS WITH TITANIUM VALVES
Conventional valves begin to 'float' at faster engine speeds, restricting ultimate performance so Lexus engineers installed larger titanium intake valves. This allows increased air and fuel into the cylinders and reduces heaviness so they perform better at higher engine speeds.
DUAL VVTi OPTIMISES PERFORMANCE AT ALL ENGINE SPEEDS
For enhanced output whatever the engine speed, the timing of both the intake and exhaust cams is continually retuned by Dual Variable Valve Timing with intelligence (VVT-i). On the intake valves, Electric motor driven VVT-iE which responds much faster, delivering further gains in performance.
A FREE BREATHING DUAL INTAKE SYSTEM
A dual stage cold air intake optimises airflow into the engine according to engine revs. To increase air velocity into the cylinders at lower speeds for increased torque, only the primary intake is used. Above 3600 rpm, the larger secondary intake opens for increased high end performance, also contributing to the IS F's distinctive high speed howl.
POWERFUL RACE BRED EXHAUST PITCH
This is a Lexus unlike any you've ever heard. Its exhaust system was optimised for a crisp exhaust note at low to medium speeds. Then at higher speeds it unleashes a sound that is music to the ears of those who crave performance.
WORLD'S MOST ADVANCED 8-SPEED TRANSMISSION
The IS F is equipped with an 8-speed Sports Direct Shift (SPDS) transmission that upshifts in a mere 0.1 second, which is as fast as a manual in the hands of a top racing driver. Downshifts in a mere 0.3 seconds are accompanied by blips of the throttle (like a true race car) for smoother downshifting performance.
SPORT SHIFTING MODE, A LEXUS FIRST
Flick the toggle switch on the steering column and you've a choice of 3 shift settings, for ultimate smoothness or ultimate performance. In 'F-Sport' mode, the transmission works together with the VDIM, steering and engine controls, to deliver a crisp, high performance shifting performance.
EXPLORE YOUR LIMITS WITH SPORTS VDIM
You've the choice of three settings of the Vehicle Dynamics Integrated Management (VDIM). When you want maximum assistance especially in challenging road conditions, 'Normal' mode improves performance and provides smoother behaviour at higher speeds. 'Sports' mode tailors the throttle, steering and suspension settings for crisper sports performance. Or switch the VDIM to 'Off' to take the I SF all the way to its dynamic limits.
RACE TUNED SUSPENSION SETTINGS
This is one high performance car you'll fell comfortable about driving day after day. Race track development work has resulted in firm spring settings and extra stiff dampers for flatter cornering. Multilink suspension front and rear adapts willingly to ever-changing road contours, for optimum grip with renowned Lexus levels of comfort and refinement.
