2011 Lexus IS F Competes in Car & Driver’s Lightning Lap

2011 Lexus IS F in Car & Driver's Lightning Lap 2011

The 2011 Lexus IS F took part in Car & Driver’s annual Lightning Lap at the Virginia International Raceway, and found that the freshly revised sedan has really stepped up its game:

Three years back, an IS F turned a less-than-impressive 3:14.0. We said then, “A little attention to springs and damping might make this eager contender a real champ,” as the stiffly sprung F zapped confidence in high-speed corners.

Boy, were we right. Lexus has since tweaked all suspension elements. Spring rates are down in the front and up in the rear, and there are larger anti-roll bars, stiffer subframe bushings, and longer bump stops, which effectively increase spring rates when the car is nearing its maximum roll angle. Lexus also lightened the front hubs and control arms and slapped a Torsen limited-slip differential in the rear axle. The result is BMW M3–matching performance around VIR (3:05.4).

There’s variables to consider (weather, tires, etc.), but the numbers don’t lie — the 2011 IS F update is a serious upgrade, and shows the power of continual improvement. These changes have successfully put the sedan right up to its most successful competitor, and it sets the table for some very interesting comparisons in the future.

  1. Come on IS F!
  2. Nice! Always knew that The Pursuit would lead to an improved IS-F.
  3. The IS-F needs to go on a diet.

    I thought the same thing. That side picture just looks bizarre. It looks like the wheels are tiny and the hood has always been odd. Hopefully, the next-gen IS will take into account the extra space for the big V8....oh yeah, and give us a coupe (not convertible).

    Certainly not the most flattering photo, that's for sure. The good news is that the F version will be a key element of the next-gen IS development, so we should see the design better equipped to handle the mods.
