Used 2017 Mercedes-Benz AMG GT Coupe Trims Comparison

The standard GT comes standard with 19-inch wheels, LED headlights, keyless ignition and entry (Keyless Go), a rearview camera, parking sensors, dual-zone automatic climate control, heated eight-way power-adjustable seats (with power-adjustable lumbar adjustment and side bolsters), driver-seat memory functions, simulated-leather and suede upholstery, and a power tilt-and-telescoping steering wheel. Also standard is forward collision warning (with emergency automatic braking), the COMAND infotainment interface (8-inch display, knob and touchpad controllers), voice controls, a navigation system, Bluetooth, two USB ports, satellite and HD radio, an auxiliary audio jack and a media player interface.

The GT S gains a more powerful V8, a three-mode adaptive suspension, upgraded wheels (19-inch front, 20-inch rear), an upgraded exhaust, a power-operated trunklid, leather upholstery and a 10-speaker Burmester surround-sound audio system. Apart from its engine, all of the extra GT S content is optional on the base GT.

Options are available for both. The Lane Tracking package adds blind-spot monitoring and lane departure warning systems. The AMG Aerodynamics package adds a fixed rear spoiler, a deeper front splitter and special front air-dam modifications. Stand-alone options include carbon-ceramic brakes, forged wheels, adaptive cruise control (Distronic Plus), a panoramic roof, various upgraded leather seat and interior trim, and an 11-speaker Burmester surround-sound audio system.

The GT S is further available with the AMG Dynamic Plus package, which includes revised engine, steering and suspension tuning, plus dynamic engine and transmission mounts.

Every 2017 Mercedes-AMG GT is powered by a turbocharged 4.0-liter V8 connected to the rear wheels through a seven-speed, dual-clutch automatic transmission. The base GT version of this engine produces 456 horsepower and 443 pound-feet of torque, while the GT S produces 503 hp and 479 lb-ft of torque.

In Edmunds testing, a GT S went from zero to 60 mph in 3.6 seconds, which is suitably quick for this class of car, though some rival all-wheel-drive sports cars post even better numbers.

The EPA estimates that both versions will return 18 mpg combined (16 city/22 highway), which is respectable considering the GT's prodigious power.
