Major changes included: The IS received a complete redesign in 2006. In its second generation, the IS is offered in a RWD IS250 and AWD IS250, as well as a RWD IS350 trim. It drops the IS300 trim from the previous generation. The IS250 uses a 2.5 liter V6, while a 3.5 liter V6 injects 306 horsepower into the IS350. A Premium Package adds heated seats and Maplewood trim, while a Sport Package adds a sport tuned suspension and Xenon HID headlights.
