The IS-F gets pumped way up with a modified version of the Lexus 4.6-liter V8, now enlarged to 5.0 liters. Lexus is predicting final output to be around 400 horsepower and more than 350 pound-feet of torque, with a redline of 7000 rpm. It sends that power through an eight-speed automatic transmission equipped with a sport mode that enables lightning fast shifts via shift paddles located behind the steering wheel rim. In normal, hands-off, fully automatic operation, the transmission, should shift unobtrusively. (It's also used in the LS 460.) The suspension is lowered by one inch over the current IS models, and the IS-F boasts firmer springs and big tires on 19-inch diameter alloy wheels, all designed to deliver enhanced road grip. A recalibrated VDIM electronic stability control system allows more aggressive driving and can even be turned off.The Lexus IS-F is all new for 2008.
