New HID headlamps with LED daytime running lamps are standard on the 2011 Lexus IS 350 F Sport and available for the IS 250. Keeping with Lexus’ attention to detail, the 2011 IS models feature new-design standard 17-inch and optional 18-inch wheels, along with revised exterior color choices.The Lexus IS 350 AWD model joins the IS 250 AWD, which has accounted for 30 percent (nationally) of IS 250 sales since the model’s introduction.
Now, 2011 Lexus IS 350 F Sport customers can have the traction and grip of all-wheel drive with the Lexus IS 350′s higher performance capability.The F Sport Package available for the 2011 IS 250/350 RWD takes inspiration from the IS F ultra-performance sedan, combining special suspension and steering tuning and 18-inch wheels with distinctive design touches. Giving the IS 250 and IS 350 F Sport Package model a sporty demeanor are a front lip spoiler and rear deck spoiler, plus the 18-inch alloy wheels with a dark super-chrome finish.

2011 Lexus IS 350 F Sport models provide a sporty driving experience while also offering a supple, quiet ride. The double-wishbone front suspension and multi-link rear suspension use high-strength steel and aluminum components to reduce unsprung weight. Sophisticated monotube shock-absorbers integrate multi-leaf linear control valves to optimize damping force, plus internal rebound springs for firmer body control without degrading ride comfort.
The all-wheel-drive system available for the IS 250 and IS 350 provides extra traction in diverse driving conditions. A planetary-gear center differential and a wet-type multi-disc clutch control front-to-rear power distribution. The system normally sends 70 percent of available power to the rear wheels to provide the performance advantages of a rear-drive car and will vary the torque-split ratio from 30:70 to 50:50 in response to driving conditions and driver input. The AWD system’s electronic-control strategy takes inputs such as steering and throttle angle from driver activity combined with vehicle signals from wheel speed and yaw rate sensors.
