This year the BMW Motorsport division is celebrating its 50th anniversary and by the anniversary the Bavarians are talking about their most interesting developments. Previously, they shot a video about secret BMW M prototypes, and now they have exhibited more famous, but no less rare models in the museum. The video is published on the official BMW Motorsport YouTube channel.

The video showed three extreme BMW M concepts. They became famous, but never went into production. Now they have become part of a special anniversary exhibition at the BMW Museum.
So, the famous BMW M5 E34 was originally planned to be released not only as a sedan and station wagon but also in the body of a convertible. However, the project was not approved and the car remained in one copy. It is equipped with a 3.8-liter inline-six with 340 hp.

The only one left is the BMW M8 sports car with a 6.1-liter 640-horsepower V12 from the legendary McLaren F1 supercar. For a long time the car was considered lost, but it was found and restored.

The third prototype is a BMW Z3 M convertible with a huge V12 under the hood. This 5.4-liter 326-horsepower engine is paired with a 6-speed manual transmission. The engine was considered too heavy for the compact Z3 and the sports car was also not put into production.
Now, these prototypes have become part of the BMW Motorsport Museum along with other famous models. The video also shows the BMW 3.0 CSL – one of the best racing cars of the 70s. By the way, soon the coupe will have a modern successor.
