They have tried with NA motors to get the efficiency but it is not possible at the price point of M cars- plain and simple. They didn't want to go turbo for the torque or any other reason it is getting cleaner and more efficient as per world wide regulations- there game has changed. And I hate to bring this all back to Brabham but M built that turbo..
I understand that the industry in now slaved to MPG and emissions, but GM gets 26mpg out of the huge Vette V8. The next C7 5.5L DI is said to improve even further on that, pushing highway MPG into the 30's. So no, turbo is not the only solution.
