Tearing around a racetrack would probably differentiate the cars, too. The GS F uses a naturally aspirated, high-revving V-8 that's good for 467 horsepower at a zingy-high 7,100 rpm – substantially more than the GS 350 (306 hp) or hybrid GS 450h (338 hp between the engine and electric motor), F Sport or no.

Lexus will show the 2016 GS F at next week's 2015 North American International Auto Show in Detroit, and we expect it to go on sale sometime late this year.
