The wider fenders are a dead giveaway we're dealing with the next G63.

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-litre 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 and 627 pound-feet, 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 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 100 kilometres per hour before maxing out at 210 km/h. The diet should also pay dividends in terms of fuel economy over the existing G63 rated by NRCAN at 20 litres per 100 kilometres in the city and 16.6 L/100 KM on the highway.

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.
