After the global launch of the new generation Mercedes Benz A-Class, it’s now time for the in-house performance sub-brand, Mercedes AMG to show off the work it’s done to the big and brash Geländewagen. The first AMG model, once again dubbed as the Mercedes AMG G63, is a high-performance box that trades its predecessor’s twin-turbocharged 5.5-litre V-8 engine for the latest twin-turbo 4.0-litre V-8. The new engine produces 577 horsepower and 627 lb-ft of torque, gains of 14 horses and 66 lb-ft over the previous G63, and a healthy 161 hp and 171 lb-ft over the standard 2019 G550’s version of the twin-turbo 4.0-litre V-8. A nine-speed automatic transmission with steering-wheel-mounted paddle shifters replaces the prior seven-speed gearbox.
According to Mercedes, the new powerplant provides the G63 with enough firepower to blast from zero to 60 mph in 4.4 seconds. Top speed is said to be 137 mph, although opting for the available AMG Driver’s package ups that mark to 149 mph. However, both figures beat the old model’s 130 mph top speed.
Like the standard G550, the G63 has a default 40/60 front-to-rear torque split. And at its core, the G-class remains an off-road tool, with the G63 retaining its less powerful stablemate’s front, centre, and rear lockable differentials and low-range transfer case with 2.93:1 gear reduction.
Aside from its powertrain, the G63 separates itself from the standard G550 by way of its AMG-specific Panamericana grille design, more aggressive front bumper, traditional side-exiting exhaust pipes, and flared wheel arches. Wider wheels cover giant brakes are squeezed by red brake callipers. An optional AMG Night package brings darker headlamp, taillight, and indicator lenses, along with black-painted exterior items, including the side mirrors, parts of the spare-tire cover, the trim within the front and rear bumpers, and the wheels. Inside, all G63s include a flat-bottom steering wheel with a thicker rim.
Other upgrades inside the cabin mirror the 2019 G550— significantly more leg- and elbow- room in both rows, a more modern dash design, and more technologies, including 12.3-inch displays for the instrument cluster and Comand infotainment system. A head-up display is not available, unfortunately; it would neither work with the G’s super-upright windshield nor fit inside the relatively-short dashboard. – Press Release – Mercedes
