The performance version of the IS, the IS F, might be called an "executive muscle car," and it boasts a 5.0-liter V-8 engine. For 2011, some changes have been made to option packages and interior trims.

For 2011, a new limited-slip differential has been added to the IS F's standard equipment, along with upgrades to the suspension tuning and power steering, and daytime running lights. The IS F features 19-inch wheels, Brembo brakes, black leather suede seat inserts, and other upgrades from the standard IS trim.
