Test drives quickly revealed that both the IS 250 and the IS 350 offer significantly better-than-adequate acceleration. Of course, the IS 350 is the hot rod of the two, boasting...
a laudable zero to 60-mph sprint of 5.6 seconds. In around-town, freeway commute and open two-lane touring, the IS 250 feels completely in its element, but we have to admit the added 102 horsepower of its IS 350 sistership is appealing.
Steering is sharp and direct, although some might complain of a bit too much boost. With a double wishbone front suspension and a multi-link rear, plus either Vehicle Stability Control (IS 250) or the more sophisticated Vehicle Dynamics Integrated Management system (IS 350), the car has both traditional and New-Age technology to foster superior handling.
