    • Weistec Engineering releases M157 AMG 5.5 liter bi-turbo V8 upgrades for the G63 6x6 AMG

      The G63 6x6 AMG is an absolutely insane monster of a vehicle that is basically a twin turbo all wheel drive German tank with power sent to six wheels. Brabus is importing these G63's as MBUSA does not at $850k+ a pop. What you may not know is that Weistec is also importing these 6x6 G63 AMG's. Not only are they importing them but they are also upgrading them with the bevy of tuning parts available in the Weistec M157 AMG engine catalog.


      Take a moment to let this sink in. You can in theory have a 6x6 G63 AMG with upgraded Weistec M157 turbochargers sending somewhere in the region of 700 horsepower to all six wheels. That much power moving 9000 pounds of six wheeled German metal? Yes, please!

      The pockets necessary to get a 6x6 G63 AMG and then modify it on top obviously need to be deep. Very, very, very, very, deep to make a point of emphasis. If you have the money these photos below certainly make a strong argument for acquiring this vehicle and upgrading the turbochargers. The exclusivity is worth every penny.

        R1 would be better suited and this can take them off road after the R1 gets away.

        Dear god. If only I was rich. I can't even imagine the savagery of one of these things. I wonder what these will go for on the used market.

        I don't see this thing dropping on value. We're talking only a handful around with a very niche clientele.
