The GT uses a front mid-engine, rear-wheel drive layout, with the engine inside the vehicle’s wheelbase. The spaceframe chassis and body are made out of aluminium alloys, while the boot lid is steel and the engine bonnet magnesium. The suspensions are double wishbones front and rear, with forged aluminium wishbones and hub carriers.
The car is powered by a front-mid mounted M178 4-litre twin-turbo V8. This new V8 is in “hot inside V” configuration—with exhaust and turbochargers inside the cylinder banks to reduce turbo lag—and uses dry-sump lubrication. Power is sent to the rear wheels through a transaxle 7-speed AMG Speedshift dual-clutch transmission; the GT S model employs an electronically controlled mechanical limited-slip differential.In a road test executed by Car and Driver, the AMG GT S accelerated from 0–60 mph in 3.0 seconds and ran the quarter mile in 11.2 seconds.
