When we pressed on the
2010 Lexus IS F's throttle, our first impression was that Lexus' claimed horsepower figures were more than a bit conservative. After...
... two upshifts we were shattering the highest speed limit in the U.S. We didn't disarm the IS F's stability control for the curvy sections, but, unlike similar systems, it allowed very aggressive driving before it kicked in. With wider rear tires and 54 percent of its weight on the front wheels, the IS F can lose front grip first if you get into a corner too fast – but by that time you'll be going way too fast for public roads, anyway. On the other hand, that chassis behavior is ideal for overly aggressive street driving or track-day novices. On the whole, the ride comfort is perfectly acceptable on smooth roads, but – understandably, given the car's capabilities – not so terrific over uneven pavement.
