M37/m50???
Last time i checked, E39 M5 = V8 and E60 M5 = V10
The way the ecomomy is going as well as the energy crisis. I do not think they will be introducing such large engine displancement in their cars. Look at how Audi discontinued the 8 cyl in their S models and replaced them with a turbo 6cyl with is more fuel efficient. I always thought V8 was a waste in a car. Why add weight and sacrifice handling when you can boost a V6 and get the same power if not better.
