With 550 horsepower and 531 pound-feet of torque at its disposal, the current Mercedes-Benz E-Class E63 AMG  is one of the quickest sedans you can buy nowadays. However, the midsize, German four-door is far from reaching its full potential in its standard guise. The sedan  is even more capable when an S badge  is added to its name, which comes with an additional 27 horsepower and 59 pound-feet for a total output of 577 horsepower and 590 pound-feet.

Impressed? You should, because you can’t find that many ponies in a BMW M5  and the Audi S6  is even further behind. But don’t hold your breath just yet, the Germans have spawned an even more powerful iteration of the E-Class  , one that boasts incredible power, torque and performance figures rarely seen in a midsize sedan.

The Germans we’re talking about do not reside in Stuttgart, where Mercedes-Benz  established its headquarters 88 years ago. Rather, they are located in and conceive their beastly creations in Bottrop. In case it doesn’t ring a bell, we’re talking about Brabus, the company behind the most ludicrous Mercedes-based vehicles ever created.

It’s newest product goes by the name of E63 AMG 850 6.0 Biturbo and it’s a sedan that could smoke some of the most powerful muscle cars available right now, including the lightning-fast Shelby GT500 Super Snake.

The 850 6.0 Biturbo is still an E63 AMG on the outside, but Brabus did a lot of wind tunnel testing while developing additional body components. Aside from a spoiler lip attached to the underside of the bumper, the front end isn’t different from an aerodynamic stand point. However, the AMG’s has received an extra dose of villainy via blacked-out air intakes and front grille, with the latter carrying the big "B" emblem at the center.

Round back, the larger diffuser and the reshaped exhaust piper are the main details that catch the eye, along with blacked-out trim, badging and trunk-lid spoiler. When viewed from the side the Brabus 850 shows off its carbon-fiber mirror caps, new wheels and updated brake rotors and calipers. Rounding off the overall look is a stunning burnt orange hue with a candy finish. Brabus is probably offering several exterior paints, but the one shown here is just screaming for attention.

Upholstery modifications are limited to Brabus’ exclusive and handcrafted fine leather, but the fact that customers can order it in absolutely any color is a pretty big deal. The Germans also took the liberty to fit the steering wheel with aluminum shift paddles and a set of Brabus Race pedals.

Everything else in the cabin is standard Mercedes-Benz E63 AMG, but that’s far from being an issue, as the sedan very well equipped and sits high on the luxury ladder in its segment.
