Luxury auto tuner Brabus has introduced a new custom build based on the 2018 Mercedes-AMG S63.

Brabus calls the refined model the 800. In typical Brabus fashion, it tweaks the power considerably. Of course, that’s exactly what Brabus is known for—taking high-end, high-performance cars and releasing their potential from the constraints of standard production. The 800 includes the Brabus B40S power kit, with two new turbos.

The vehicle’s performance specs are amped up to 800 HP and 737 lb-ft of torque; the car can move from zero-to-62 mph leap of just 3.1 seconds, and reach a top speed of 186 mph. The standard S63 4L V8 pumps out 603 horsepower and 664 lb-ft of torque, and can get to 62 MPH in 3.5 seconds.

Brabus didn’t just improve the vehicle’s specs, though. In fact, Brabus added a number of luxury touches to give the vehicle a custom look.

New additions include a carbon front lip, front skirt additions, rear spoiler, rear skirt, and rear diffuser, and a custom exhaust. Other Brabus touches include a custom suspension module, bespoke brakes, and new 21-inch Monoblock M wheels. The interior features ventilated seats, custom floor mats, custom steering wheel, fine leather trim, and more.

Available for $394,000.
