2012 Lexus IS F

The 2012 Lexus IS F is a high-performance sedan featuring a naturally aspirated 5.0-liter V8 engine producing 416 horsepower and 371 lb-ft of torque, paired exclusively with an Aisin AA80E 8-speed automatic transmission. Unlike the standard IS models, the IS F did not have other engine options such as a V6 or a 2.5 liter.
