Most notably, the naturally aspirated 5.5-liter V8 from the current G55 is expected to be yanked out in favor of Merc's new twin-turbocharged 5.5-liter powerplant. This means the new AMG Wagen should produce somewhere between 525 and 545 horsepower, sending its power to all four wheels.
Additionally, it appears that a modest visual freshening is in store, with the G55 getting new side mirrors and a revised front fascia, encompassing what appears to be a three-intake design. New LED running lamps should also be in the cards, and while one G55 prototype was sporting a new set of wheels, we're hoping those gaudy rollers don't make it to production. Well, except maybe in Dubai.
