When a 4×4 Is a Bore, Try a 6×6 for the Fix

There aren’t many places on Earth that a fully loaded 4X4 truck can’t find. Think of the Land Rover Defender and all of its desert adventures or the Toyota Hilux and its journey to the North Pole. A good 4-wheel-drive truck, equipped with the right gear and proper modifications, can go virtually anywhere.

For people who don’t like the words “virtually” or “modifications,” there’s a new player in town:

The Mercedes-Benz G63 AMG 6X6.

This truck just might be able to go anywhere on the planet, provided it’s covered in less than 40 inches of water and free of things like… oh… molten lava.

At first glance you’d be forgiven for thinking the monster seen here is a photoshopped prank. An extra axle and set of tires just looks unnatural on any vehicle that isn’t an 18-wheel semi truck. This Benz, though, exists. And the specs are completely insane!

The G63 6X6 uses the same engine as its two-axled G63 brother, a 5.5-liter bi-turbo V8 that produces 544 hp and 560 lb-ft of torque, which is sent via a torque split of 30-40-30 between the front axle and the rear axles. AMG fitted the 6X6 with 5 mechanically locking differentials, electronically controlled through 3 differential lock switches located in the cabin. With its 37-inch tires, the vehicle has a ground clearance of 18.1 inches and can wade through over 3 feet of standing water.

Take that, Defender.

If you have to ask about fuel economy, well, this probably isn’t the vehicle for you. Engineers didn’t even try to improve economy with the added weight of the extra axle and its components. Instead, they just added an auxiliary 16.3-gallon fuel tank. Considering the 4WD G63 is rated by the EPA at just 12 mpg in the city, you can assume the numbers for the 6X6 will be downright abhorrent.

So far, two development vehicles have been built, and I don’t imagine it would take much for MB to put this into very limited production.

Do you think there’s a need for the Mercedes-Benz G63 AMG 6X6?

  1. Randy, I click the virtual “like” button on your comment! This seems to push past the boundaries of good taste, indeed.

  2. Since the folks at AMG only built this monstrosity to sucker Arabs out of some of their oil money, that is the apparent need. And for that crowd, who cares if it gets the mileage of an M1 tank? They own the oil well. It does, at least, forever lay to rest the myth that AMG has any kind of good taste or class.
