"IS" stands for "Intelligent Sports (Sedan)." "F" in the model name was derived at the Fuji Speedway.
The engine (2UR-GSE) was jointly developed with Yamaha Motor Co., Ltd., using the 2UR-FSE (V8, 5-liter) for the LS 600h as its base. The engine employed the D-4S mechanism that combined direct-in-cylinder injection and port injection methods, producing the maximum output of 423 PS and the maximum torque of 505 Nm (51.5 kgm)/5,200 rpm. The transmission was an 8-speed Sport Direct Shift (SPDS) automatic. The styling significantly differed from that of the Lexus IS, resulting from the aerodynamic tuning and the extended front overhang and bulging hood to accommodate the V8 engine. The front fenders had slits in them to improve the cooling performance. The brakes were jointly developed with Italian manufacturer Brembo. The wheels employed 225/40R19 tires for the front and 255/35R19 tires for the rear. The 19-inch lightweight forged aluminum wheels were designed to deliver efficient heat dissipation for the brakes, with a specific direction of rotation assigned to each. In July 2009, the Lexus IS F adopted a 5-pinion torque-sensing limited slip differential (Torsen LSD).
