2019 Mercedes-AMG G63 is a 577-hp beast

 Few vehicles are as over-specified for their typical habitat as the 2019 Mercedes-AMG G63. The automaker’s iconic ‘G Wagon’ may be a legitimate off-roader, but its unmistakable design is more familiar from Malibu than out in the mud. With this latest generation, then, the question has to be whether Mercedes has diluted the G-Class for the inevitable on-road tastes, or if this rebooted beast is as flagrant as ever.

It’s a bigger SUV than it used to be. 2.1-inches longer, and 4.8-inches wider. You get more shoulder space as a result and, most importantly, almost 6-inches more legroom in the rear. Oddly there’s still only a regularly-sized sunroof, rather than the expansive panoramic glass we’re used to from modern luxury cars.

Kicking off from $247.700 (plus on-road costs), the 2019 Mercedes-AMG G63 leaves nothing to the imagination. Under its ladder-frame chassis is a 4.0-litre twin-turbocharged petrol V8 engine that pumps out 430kW of power and 850Nm of torque.

It’s mated to a nine-speed multi-clutch gearbox and a permanent all-wheel-drive system that affords a 40/60 front/rear torque split. Comically, it features a stop/start system and cylinder deactivation that allows it to periodically run on four cylinders.

Weight reduction

These efforts combined with a 170kg weight reduction over the previous model bring an official fuel consumption of 13.1 litres of fuel per 100km. You’ll never see that number – even with a stack of highway driving, the closest we came to that was 19.5L/100km. Luckily there’s a 100L fuel tank to keep you moving.

Mercedes claims the trot to 60 mph takes 4.4 seconds – 0.9 seconds ahead of the prior G63 and equal to that of the Mercedes-AMG GT53 4-Door. Top-speed stands at an electronically limited 137 mph, but, an available Driver’s package can push the G63 to 149 mph.

Fuel economy figures remain under wraps, but it’s safe to assume the G63 will gulp gas at a greater rate than the G550, which the EPA rates at an unremarkable 13 MPG city17 MPG highway, and 14 MPG combined.
