The letter F is an auspicious one in Lexus lore. Back in the mid-'80s, when the Lexus brand was still in the planning stages, Toyota insiders referred to the prospective luxury division as "Circle F." And the car that put Lexus on the map, the LS 400, was known internally as Flagship One, or F1. For 2008, the letter F is back: The company has decided to crash the über-sport sedan party with the 2008 Lexus IS-F, a hard-edged performance car based on the IS-series sedan and aimed squarely at perennial magazine-cover fodder like the Audi RS4, BMW M3 and Mercedes-Benz C63 AMG.
The IS-F marks the official launch of Lexus' F line, and it's akin to the aforementioned competitors' in-house performance divisions. As such, Lexus has gone to great lengths to differentiate the IS-F from its more sedate IS-series brethren. Take the IS-F's exclusive power plant, for example, which begins life as the gas-swilling half of the LS 600h L's hybrid engine and then gets a thorough makeover from Toyota's longtime performance partner, Yamaha. The end result is a 5.0-liter V8 that churns out 416 horsepower and 371 pound-feet of torque, compared with 306 and 277, respectively, from the IS 350's already potent 3.5-liter V6. Likewise, the IS-F eschews the IS 350's six-speed automatic transmission for a heavily modified version of the LS 460's eight-speed unit that boasts Ferrari-quick upshifts and automatic throttle blips on downshifts. The singularity and complexity of this powertrain serve notice to the old guard that this Lexus means business. Like its F1-cum-LS 400 forebear, the 2008 Lexus IS-F is designed to go toe to toe with the best.
