Lexus redesigns its sporty compact sedan for 2006 with new styling and available all-wheel drive. IS borrows its basic architecture from Lexus's larger GS sedans and loses its wagon body style for '06. Compared to the 2001-05 IS 300, the '06s are some 3 inches longer and wider on a 2.4-inch-longer wheelbase. The IS 250 versions have a 204-hp V6 and offer rear-wheel drive or AWD. The IS 350 has a 306-hp V6 and rear-wheel drive. A 6-speed manual transmission is standard for the rear-drive 250. Available for the rear-drive 250 and standard for the other models is a 6-speed automatic with a manual shift gate and steering-wheel paddles.

All come with ABS, traction/antiskid control, front torso side airbags, curtain side airbags, and front knee airbags. Also standard are leather upholstery and a sunroof. Available are a sport suspension, wood interior trim, and heated/cooled power seats. An optional voice-activated navigation system includes a rearview camera and wireless cell phone link. Rear obstacle detection and steering-linked bi-xenon headlights are also available. So is adaptive cruise control. A new option is Lexus's Pre-Collision Safety System, designed to automatically cinch seatbelts and apply brakes if an unavoidable crash is detected.
