The heart of the exciting GS F is in its high-performance, naturally aspirated 5.0-liter V8, engineered for low weight and high strength with forged connecting rods and titanium intake and exhaust valves that allow a 7,300-rpm redline. Add to the mix optimized intake and exhaust manifolds, and the result is an engine that delivers 467 horsepower and 389 lb.-ft. of torque.
The high-pressure D-4S direct injection system, which also uses port fuel injectors, allows a high 12.3:1 compression ratio for optimized performance and efficiency. Variable Valve Timing (VVT-iE) enables the engine to operate in the Atkinson cycle at cruising speeds and can switch to the Otto cycle for higher performance levels when accelerating.
It sounds amazing through the Lexus “F” trademark stacked tailpipes, too. The special exhaust system emits a rumbling baritone note, and Active Sound Control (ASC) electronically “boosts” the sound in the cabin via the audio speakers – an optional experience that the driver can turn on or off.
