Pegged as the ‘ultimate wolf in sheep’s clothing,’ Mercedes tuner Brabus has unveiled its new V12 Biturbo C-Class sedan that it plans to present at tomorrow’s Frankfurt Motor Show.

First the sedan, then the coupe and now the cabriolet: With the 800-hp (788-bhp) / 588-kW BRABUS 800 V12 Biturbo twelve-cylinder high-capacity engine in the body of the open-top Mercedes E-Class ...

The addition of the 5.5-liter V12 from the Mercedes S600 to a G-wagen by BRABUS is the sort of wild idea you'd respect but, honestly, it's nothing amazing. Mercedes tuners love swapping motors.

That tuner is, of course, Brabus, and its clientele is on the same page when it comes to displacement: the more, the merrier. Brabus' answer for that subtle, understated clientele is the G V12 900.

Built off the legendary Mercedes-Benz G-Class, the G V12 S Biturbo is powered by a modified version of the twin-turbo V-12 found in the S600. Brabus took the liberty of boring the engine from 5.5 ...
