330 lb-ft, 1,300 and 4,500 rpm
The N55 already makes those numbers as it is, BMW just underrates the motor in the 335i from the factory.
So my question then becomes, is BMW's listing of the 640i/740i cars making 315hp just a marketing ploy, and it's the same engine with no other changes? Is there a difference in the N55 engine between the 640i/740i and 335i?
Mercedes and other automakers have done this for years, underrating motors of the lesser models that use the same engine as the higher end models.
