Beneath the hood of the stylish two-door Benz is an AMG-worked version of the brand's 3.0-liter twin-turbo V-6 good for 362 horsepower and 384 lb-ft of torque. Hardly a slouch and can send the 4,000-lb coupe to 60 mph in just 4.6 seconds. A rapidly firing nine-speed automatic handles gear-shifting duty, while power is sent to all four wheels via an AMG-tuned 4Matic system that shifts 69 percent of torque to the back during normal operation.
