There are few aftermarket tuning firms like Brabus. The German aftermarket has officially revealed one of its latest, and borderline insane, projects: the Mercedes-Benz S63 AMG Coupe 850 6.0 Biturbo. Trust us, this is not just some rim and diffuser add-on job. The 5.5-liter twin-turbo V8 has been bored out to 5.9 liters, and has been further given larger turbochargers, a custom crankshaft with longer stroke, new intake module with a bigger air filter, and carbon-fiber air ducts.

There's even gold heating-reflection sheathing on the intake and charge pipes. Its creators also performed an ECU remap and added on a stainless-steel exhaust. Therefore, output has been increased to 838 hp and 848 lb-ft of torque. Power is sent to all four wheels via the familiar seven-speed automatic transmission. Performance times? Try 0 to 62 mph in only 3.5 seconds and a top speed of 217 mph. That's just ludicrous. A carbon-fiber aerodynamic body kit and 21-inch cross-spoke alloy wheels round out the exterior package. Official pricing for the modifications isn't available, but buyers will first need to purchase the donor car, which bases at nearly $120,000. Awesomeness doesn't come cheap.
