    • Mercedes-AMG gives the 2019 G63 577 horses of M177 4.0 liter twin turbo V8 power

      Mercedes-Benz did a press release last month on the off-road capability of the new 2019 G-Class model. What they did not mention is that the G63 would be replacing the venerable M157 5.5 liter twin turbo V8 with a custom M177 unit.


      The reason custom is brought up is because at 577 horses the M177 in the 2019 Mercedes-AMG G63 is more powerful than any other M177 other than the E63 and matches the output of the dry sump M178 in the AMG GT R. It looks like they gave the M177 the GT R turbos and more aggressive tuning but without the oil system.

      So, 577 horsepower and 627 lb-ft of torque sent through a 9-speed automatic. The torque split is also 40:60 front to rear now.

      So the interior is updated, the exterior is updated, the transmission is updated, the suspension is updated, the engine is updated, and, well, they basically updated everything.

      What is there not to like?

        I think it looks amazing.

        Combine the updated looks with the other changes and a new motor and its a winner.

        Should be very fun to drive with the M177.

        I prefer a more modern exterior ie. Range Rovers. But bias I guess as have one. I've never been keen on them. But one mans lamb is another mans mutton and vice versa.

        "G63 is more powerful than any other M177" the E63S is more powerful isn't it ?

        Yep I was thinking M178 which it matches the GT R.

        Thanks, I'll edit.
