The all-new 2016 Mercedes-AMG GT S is the successor to the Mercedes-Benz SLS AMG. Unlike its gull-wing predecessor, which was fitted with a naturally aspirated 6.2-liter V8, the modernized GT S arrives with conventional doors and new twin-turbocharged 4.0-liter rated at 503 horsepower and 479 lb-ft. of torque. Lighter and more agile than the SLS, the GT S is a true driver’s car.
