It was only a couple of weeks ago when we shared a batch of spy shots with the next-generation Mercedes G-Class and now the venerable off-roader is making a comeback in fresh spy content. This time around, it’s the stronger G63 as evidenced by the wider fenders to make room for the chunkier wheels, while at the front it has larger air vents to improve engine cooling.

Thankfully, Mercedes is keeping the new G-Wagen (W464) just as boxy as the original 1979 model and in the AMG specification it’s going to look more aggressive to match the extra grunt coming from underneath the hood. Power is expected to be provided by the now familiar biturbo 4.0-liter V8 available in a wide array of models and in multiple outputs. In its strongest iteration, the E63 S, the eight-cylinder motor unleashes 603 horsepower (450 kilowatts) and 627 pound-feet (850 Newton-meters), but it’s too soon to say whether the G63 will receive the full power. Even if it won’t, it will still be stronger than the outgoing 563-hp model.

A weight loss of approximately 900 pounds (408 kilograms) is being mooted, although it’s hard to believe Mercedes’ engineers will be able to cut so much fat. If by any chance it will turn out to be true, it means the new G63 will be way faster than the current model that needs 5.4 seconds until 62 mph (100 kph) before maxing out at 130 mph (210 kph). The diet should also pay dividends in terms of fuel economy over the existing G63 rated by EPA at 11 miles per gallon in the city and 13 mpg on the highway, while in Europe the G63 consumes 17.2 liters and 11.8 liters, respectively.

The regular next-gen G-Class is expected to be unveiled sometime next year, with the Frankfurt Motor Show set for September likely to be the venue of choice. As for the G63, it will likely arrive in the second half of 2018 and should be followed shortly by its V12-powered G65 counterpart.
