"S65 Lightened Drivetrain Program

I love NA BMW M engines for their rapid response over their traditional competitors, yet BMW M engineers street cars first and sacrifices are made in the name of comfort. 

The front engined, rear wheel drive layouts has disadvantages in effieciencies versus the rear engined, rear wheel drive layout of Porsches.

There's more spinning metal - more weight - more losses, more resistance to inputs. 

We can drastically improve this with some sacrifices
