Take the roar from the racetrack to the on-ramp. Born on the grueling Fuji International Speedway, the 2014 IS F is the fastest, most dominant sedan Lexus has ever built. A 5.0-liter V8 engine with 416 horsepower and 0-to-60 in 4.6 seconds. It's just scratching the surface of a passion for performance that's as deep as its racing pedigree.
