There are few things in this world that go better together than a gearhead, a fast BMW, and the Autobahn, especially when you're driving an 823-horsepower Manhart BMW M8 Competition. Modern BMWs make a ton of power. The BMW M5 CS, for example, churns out 627 hp and 553 lb-ft of torque from its 4.4-liter twin-turbo V8, but that is child's play compared to what tuners such as Manhart are getting out of BMW engines. In the following video we get to see what kind of damage an 800-hp M8 can do when let free on German highways.

The test car is a rather gaudy-looking thing covered in black paint featuring gold racing stripes down the middle and sides of the car. It's basically a drug dealer's dream getaway vehicle. Manhart calls this its MH8 800 package, and it turns the standard M8 Competition into a fire-breather. To achieve 823 hp, Manhart swaps out the standard exhaust system for a great-sounding stainless steel system with valve control and also installs OPF-Delete pipes and free-flowing downpipes. An ECU remap makes these hardware upgrades come alive. The car also features a height-adjustable spring kit by KW , Manhart Concave One gloss-black 21-inch wheels, and exterior styling bits such as a carbon-fiber hood, front splitter, rear diffuser, and side sills.

In the video we get a quick walkaround of the car before it sets off for a top speed run on the Autobahn. Once up to cruising speed, the driver floors it. It is astonishing to see how quickly this car accelerates. Near the end of the video, the driver keeps his foot planted, and the Manhart BMW M8 Competition reaches 186 mph, but seems to hit a limiter. We wouldn't be surprised if it was able to hit 210+ mph.
