Take the roar from the racetrack to the on-ramp. Born on the grueling Fuji International Speedway, the 2013 IS F is the fastest, most dominant sedan Lexus has ever built. A 5.0-liter V8 engine. 416 horsepower[*]. 0-to-60 in 4.6 seconds[*]. A track-tuned suspension. It's just scratching the surface of a passion for performance that's as deep as its racing pedigree.

When it comes to delivering heart-stopping performance, the proof is in simple numbers. 416 hp[*] and 371 lb-ft of torque[*] from the IS F's 5.0-liter V8 engine help deliver a 0-to-60 time of just 4.6 seconds[*]. It's engineered to enhance high-rpm breathing, so while the driver gets a crunch of power down low, it also keeps building as revs rise, for a sense of unlimited acceleration that can't be measured in numbers.

To satisfy their craving for hardcore performance, a small group of rogue engineers created the IS F between their regular assignments. But they weren't satisfied with just creating a monster—that monster had to be legit. So they tested the IS F at some of the world's most iconic racetracks, including the IS F's home circuit, Fuji Speedway in Japan. By the time testing was complete, the result was not just a car these engineers wanted to make—it was a car these serious enthusiasts wanted to drive.
