From how I see it, main difference is BMW attempts to squeze out every last drop from their engines by using the most advanced and sophisticated technology available. This is very much alike to F1 engines. MB just slaps on two turbos or a supercharger to existing engines which works, but also has comprimises, primarily to do with fuel consumption.

Vroom vroom they actually made 3 engines far far superior to pretty much anything. The Zonda, CLK GTR & GTR supersport, they which was until recently the highest output motor from anyone (it is still probably the highes output N/A motor out there), being recently beaten by the Koenigsegg CCR which used a Supercharger to geth there.

Also dont forget these normal M engines are pretty much torqueless, yes they have high outputs but its like reving an S2000 engine you really need to wind it up to get anything out of it. The MB engines on the other hand have a 'wall of torque'. Who needs to change gears?

 

We're looking for regular production engines/cars right?

 

totally agree, great point.

AMGs suffer from supercharger whine, whereas BMW engines sound real hardcore.

 

The CLK GTR was a production car. Expensive to buy but it was a production car.

 

Woah, what car would that be? It resembles the Enzo in some way.
