Peter Lyons recently had some track time with the 2011 Lexus IS F, and talks up the changes in the new model year quite nicely:
Although the powertrain and the car’s 3800-lb curb weight remain the same, the suspension settings have been totally recalibrated…An unexpected byproduct of this revision is the car’s more compliant ride, which Yaguchi says “was a bonus but something we aimed for.” Adjustments to the steering power-assist mechanism made for more precise and accurate turn-in as well as greater feedback through the wheel.
The results are that the 2011 IS F can now be pushed even harder into corners; it stays more composed under heavy braking, at turn-in, and while experiencing changes of road camber and elevation. The IS F also exhibits less understeer and more rear wheel grip and stability. In fact, the rear end is now so tied down that a slight enhancement of front-end downforce might generate even greater all-round traction and stability.
These subtle adjustments make a significant difference — according to Lyons, the 2011 IS F tracked around Fuji Speedway almost two seconds faster than the previous model.
There’s a number of other minor details — check out the full article for a complete breakdown.
