The new member of the Mercedes-AMG family will be offered in three versions, at least initially, including the GT 53 4MATIC+, the GT 63 4MATIC+ and the range-topping GT 63 S 4MATIC+.
The most powerful version of AMG’s four-door coupe will use the biturbo 4.0-liter V8 engine, producing in that case 630hp (639PS) and 663lb-ft (900Nm) of peak torque. With the kind help of the trick all-wheel drive system, the Mercedes-AMG GT 63 S is capable of pulling a 0-62mph (100km/h) in 3.2 seconds, while flat out it’ll do 195mph (315km/h).
Opt for the “plain” 63 model and you’ll get 576hp (585PS) and 590lb-ft (800Nm) of peak torque. 0-62mph (100km/h) is 0.2 seconds slower, at 3.4 seconds, while top speed is now just 192mph (310km/h).
Both V8 models are equipped with AMG Cylinder Management that deactivates a bank of cylinders in the partial-load range and when the driver has selected the Comfort drive mode. The more powerful S version also comes with active engine mounts, which are optional in the regular 63 version.
Entry-level GT 53 models are powered by the recently-launched plug-in hybrid powertrain that combines a turbocharged 3.0-liter straight-six engine with an electric motor for a total of 429hp (435PS). The electric boost is 21hp and 184lb-ft of torque. The petrol engine also employs an electrical compressor in addition to the regular exhaust gas turbocharger, effectively killing any turbo lag. 0-62mph (100km/h) comes in 4.5 seconds while top speed is 177mph (285km/h).
V8-powered versions of the AMG GT 4 use the more responsive nine-speed MCT gearbox and a multi-chamber air suspension while the GT 53 version employs the regular nine-speed TCT transmission, as well as steel springs and adaptive dampers. Rear-wheel steering is standard on the 63 versions and an option on six-cylinder models.
All models in the Mercedes AMG GT 4 lineup are fitted with the AMG Performance 4MATIC+ all-wheel drive which continuously computes the best torque split between axles, depending on driving conditions and the driver’s inputs. The now-famous Drift mode is standard on the 63 S models, with AMG to offer it as an option in the rest of the range.
Inside you get greeted by the usual pair of 12.3-inch digital displays for the instruments and infotainment but the new feature lies on the elevated center console. The new GT 4 is the first model to feature color display buttons that control the transmission modes, suspension, ESP, exhaust system, and more. The new control buttons are supplemented by the two capacitive switches for the driving modes and volume control.
Mercedes AMG will launch the GT 4 in Europe late this summer, with pricing details to be announced closer to that date.
