You are changing the subject but if you want to go there, real world figures on this and other BMW forums show the N20 engine gets significantly better fuel economy than the N55, at least 15% better which would be at least 10% better than my N52 engine.

Yes, the Caddy 2.0T engine does poorly in this regard. But them again, these cars are not bought because they get great fuel economy. The need for greater efficiency in BMW is because of CAFE numbers. For GM, I'm guessing Cadillac is a very small part of the overall volume and they make that up by selling a lot of Cruse's and Sonic's.
