Brabus 850 6.0 Biturbo is a Mad, Mad Mercedes-Benz E63 AMG
The latest evolution of the AMG-tuned Mercedes-Benz E-Class is one of the baddest stock super sedans on the planet. The E63 AMG’s twin-turbocharged 5.5L V8 produces up to 577 horsepower in S-Model specification, while a sport-tuned fixed-torque-split 4Matic all-wheel-drive system (standard equipment on U.S.-bound E63s) makes sure as much of that power as possible gets translated into forward progress. The net result is a mid-size German luxury sedan that’s capable of going Solange Knowles on more than a few genuine supercars.
Even so, Brabus just can’t seem to leave well enough alone when it comes to cars wearing the Three-Pointed Star, even ones that have already had a thorough makeover at the hands of AMG. And the latest hardware for the current E63 to emerge from the Brabus laboratories is a power kit that takes that M157 motor from “Holy crap!” to “F*CK ME EIGHT WAYS FROM SUNDAY!!!!1!” Enlarged cylinder bores and a precision-balanced billet stroker crankshaft (to which forged billet connecting rods and pistons are attached) bump displacement up to 5.9L (Brabus calls it a 6.0, but whatevs…), while improved airflow through the cylinder heads, new turbochargers, a new intake manifold, and dual airboxes that are fed by ram air ducts hidden under the skin of the hood make sure those embiggened pots stay full for the compression and power strokes. You want numbers? Okay: Peak power is now 838 horsepower (850 metric horsepower), while peak torque is…ahem…1,069 lb.-ft.
Rear-drive 850 6.0 Biturbos will blast to 62 mph in 3.7 seconds, while 4Matic models can allegedly do the deed in a mere 3.1 seconds. Brabus says both will top out north of 217 mph, thanks to the removal of the electronic speed limiter. And oh by the way, just like the factory standard E63 AMG, the Brabus 850 6.0 Biturbo is also available as a station wagon. We’ll defer to Beavis to articulate our feelings on that factoid.
