Hang on... did I just read that it's "a more powerful version of the N54, upgraded to about 335 hp"????
If this has the DCT transmission this is basically the exact same engine as in the Z4sdrive35is? I'm not saying that's a bad thing but I expected a few more ponies out of this bad boy.
If this is the case, for the N54 135i owners, this is basically just an N54 with a mild tune and possible a better transmission. The other differences lie in suspension, weight and cosmetic goodies.
