The GT 63 also has an optional selectable "Drift Mode" which directs power solely to the rear wheels.[20] The car comes standard with an electronically controlled limited-slip rear differential and rear-wheel steering, and features an MCT gearbox with a wet clutch to handle the extra power. The GT 63 uses AMG's multi-chamber air suspension for a sportier, more adaptive ride and has cylinder deactivation mode for increased efficiency.[18]

Mercedes-AMG GT 63S

The GT 63S is the top of the line variant of the GT 4-Door and features the same 4.0L twin-turbocharged V8 engine as in the GT 63, but receives further tuning to produce 470 kW (630 hp; 639 PS) and 900 N⋅m (664 lbf⋅ft) of torque. The GT 63S will reportedly accelerate from 0–100 km/h (0–62 mph) in 3.2 seconds and attain a top speed of 315 km/h (196 mph) as tested by the manufacturer.[21] Auto Bild tested 0–100 km/h (0–62 mph) in 3.0 seconds, 0–160 km/h (0–99 mph) in 6.6 seconds and 0–200 km/h (0–124 mph) in 10.2 seconds.[22]

Additionally, all of the equipment and features from the GT 63, as well as the selectable "Drift Mode", which directs power solely to the rear wheels, comes as standard on the GT 63S as well.[12]

The GT 73 EQ Power+ Hybrid is an upcoming top of the line variant of the GT 4-Door and features the same 4.0L twin-turbocharged V8 engine with an electric motor for a combined power output of up to 600 kW (805 hp; 816 PS), and a 0-60mph (0-97 km/h) sprint time of less than three seconds.[23]
