You probably wouldn’t guess the Mercedes GLK pictured above is capable of 200.3mhp. But the V12 emblem on the hatch is a dead give away that it is, thanks in part to 750HP and 811 lb-ft of torque (limited electronically from 995 lb-ft). Who in Parnelli Jones’ name would do such a thing? German tuner Brabus, of course. From the press release:

“To achieve this kind of performance, the engine – based on the latest Mercedes 600 twelve-cylinder engine – was completely re-engineered in the BRABUS engine department. Displacement is increased from 5.5 to 6.3 liters with the help of a special crankshaft, larger cylinder bore, special pistons and piston rods. In addition the three-valve heads are precision-machined and fitted with special camshafts.

For maximum power yield the BRABUS engineers have developed a special twin turbo system with two larger turbochargers and more efficient intercoolers. Free-flow metal catalysts and a fully stainless-steel high-performance exhaust system custom-tailored to the GLK body let the BRABUS SV12 R 750 Biturbo engine breathe more freely.” (1)

For those who find traveling at 200mph somewhat less than stimulating, the backs of the front seats are outfitted with “Custom-tailored consoles” that each features an integrated seven-inch LCD screen and a DVD player. The rest of the luxury interior doesn’t look anything short of Mercedes-level either with wood trim or carbon fiber trim panels for the dashboard, doors and center console in “any color imaginable.”
