The heart of the new 2016 Lexus GS F is undoubtedly its naturally aspirated 5.0-liter V8, which has been finely tuned to deliver excellent power and responsiveness. The engine's reciprocating assembly targets lower mass with the help of lightweight forged connecting rods and titanium intake and exhaust valves, allowing it to reach a 7,300-rpm redline. Free-breathing 32-valve cylinder heads take full advantage of this engine's reduced internal friction, and aggressive valvetrain. The working angle and lift of the camshaft have been designed to achieve ample torque production for continuous acceleration throughout the rev range. Add to the mix optimized intake and exhaust manifolds, and the seamless operation of a high-performance-tuned Variable Valve Timing (VVT-iE) that delivers optimal power in all situations, and the result is an engine that delivers 467 horsepower and 389 lb.-ft. of torque..
