IS F - Even Better Performance
Lexus has increased the speed (2 seconds per lap in testing) of its
ultra high performance IS F by replacing the conventional differential.
A significant increase in traction and stability in high speed
cornering has resulted in the vastly improved track times achieved by
Lexus’s test team.
The compact Torsen LSD is capable of handling the 500Nm-plus of torque produced by the IS F’s V8 engine, and automatically diverts drive torque to the rear wheel with the most grip, for example to the outside rear wheel when cornering. The unit uses low viscosity multigrade oil to reduce bearing rolling resistance and oil agitation resistance when the oil temperature is low, and a friction adjuster has been added to suppress the stick-slip phenomenon when sliding the car and to improve quietness.
A new Fuji White interior colour scheme, with a blue leather bottom section for the steering wheel, is also now available for the IS F, together with a new buffed-finish 19-inch alloy wheel design and Ultra Blue mica exterior paint finish.
