Low, wide, and brawny, the Mercedes AMG GT turns heads even before its V8 rumble sparks to life. The second sports car developed in-house by Mercedes-AMG, following the gullwinged SLS AMG, the GT is a German take on the overlap between a sports car and a muscle car. The base GT 53 has a 469-hp, 4.0-liter twin-turbo V8 with an accompanying exhaust soundtrack full of rumble and fireworks. The top AMG GT 63 belts out 577 hp. Recent updates include various interior and exterior changes as well as a retuned suspension, refreshed infotainment system, and an available three-person rear bench seat. Forward collision warning and automatic emergency braking are standard, but blind spot warning is optional.
