The outstanding feature of the BMW M8 E31 prototype is its large 6-litre engine. V12 engines have always been amongst the most desired by true car enthusiasts, but this one is a particularly unique. The power unit, derived specifically from the S70 engine that was known for top performance, combines superiority, smooth running and enormous performance potential with an impressive appearance.
The BMW E31 is the first generation of the BMW 8 Series. It is a grand tourer built by BMW from 1990 to 1999 as a 2-door coupé, powered by either a V8 or V12 engine. Why? Because BMW made a single S70/1 engine, specifically for a one-off prototype of a planned M8 for the E31-generation 8 Series.
At a BMW press event in California earlier this year, I got up close with the M8 prototype. (It was a rare opportunity-after the project died in the early 1990s the car sat in a basement in Germany for 20 years.). Instead, an M-engineered performance version called 850CSi came out in 1992 with a far more plebian, 375-hp S70 V12.
The only completed M8 was never shown to the public, and it ended up in a. BMW M8 E31 (1990) Originally envisioned as a Ferrari competitor equipped with a special 550 bhp (410 kW; 558 PS) version of the S70 engine, essentially a bored out version of the M70 with experimental multi. Rather, variations on the original S70 used on the 850csi, the S70/2 and S70/3 were used for the McLaren F1 (The variation used on the M8 prototype was the S70/1 engine).

The E31 M8 prototype has a version of the S70 6.0-liter V-12 used in the then-new 850i coupe. This engine developed 550 hp, and was fed by a massive intake duct designed to keep incoming air as. One of BMW's best-kept secrets is the canceled BMW M8 Prototype.

Originally envisioned as a Ferrari competitor, only a single prototype was ever produced, equipped with a special 550 bhp (410 kW) version of the S70 engine, essentially a bored out version of the M70 with experimental multi valve cylinder heads. The E31 BMW M8 Prototype is arguable one of most valuable concept cars in BMW's portfolio. And it made 640 horsepower in 1990s.
With this in mind, BMW Motorsport set about developing two suitably enhanced variants with a brace of enlarged engines: the radical 6-litre M8 and somewhat more refined 5.6-litre 850 CSi. Both models adopted BMW Motorsport's tried.
