Mercedes-AMG GT / GT S

Gullwings are no longer part of the design, but the GT is still set to swoop in and snag buyers away from its archnemesis, the Porsche 911. Its three variants all have a 4.0-liter twin-turbo V-8. In the base model—if anything at this level can be called base—the engine makes 456 hp. The GT S adds 47 hp, and in the halo GT R edition, engine revisions give it 577 hp. In our testing, we got a GT S from 0 to 60 mph in 3.0 seconds. We expect the GT R to be even quicker when it debuts in summer 2017.
