The M8 Competition is BMW’s most powerful production vehicle ever, but despite bearing this bold title, it’s by no means a supercar. Nevertheless, it’s got supercar-like performance and can put a really big smile on the face of its driver.

So, the most powerful Bimmer ever can smoke a lot of big names in a straight line, with the 0-60 mph (0-96 km/h) taking 3.1 seconds in the Competition Convertible. In this spec, the 4.4-liter twin-turbo V8 pumps out 617 HP (625 PS / 460 kW) and 553 lb-ft (750 Nm) of torque, and the car has an MSRP of $155,500 in the U.S.

We know what it can do on paper, but how does it translate into the real world, when its rivals are two open-top supercars and the battle ground is the Lausitzring circuit? AutoBildSportsCars had the M8 Competition Convertible pitted against the Mercedes-AMG GT R Roadster and Audi R8 Performance Spyder, to see which one is faster around the German track.

Before checking out the video below, let’s talk specs – and more specifically, those of the other two competitors. The GT R Roadster is powered by a 4.0-liter twin-turbo V8 that puts out 577 HP (585 PS / 430 kW) and 516 lb-ft (700 Nm). The 0-60 mph (0-100 km/h) sprint takes 3.5 seconds in this model, which starts at $189,750.

The 5.2-liter naturally aspirated V10 in the R8 Performance Spyder, on the other hand, develops 611 HP (620 PS / 456 kW) and 427 lb-ft (579 Nm) in the Euro-spec version, which was the one put to the test, for a 0-60 mph of 3.1 seconds. The U.S. model comes with 602 HP (610 PS / 449 kW) and 413 lb-ft (560 Nm), and adds two tenths of a second to the sprint time, while pricing starts at $208,100.
