Difference in new 528i?

Greenkirby21 · 12-27-2010, 04:58 AM

Does anyone know what difference the new 528i has against the 128i that gives it the extra 10 hp?(it is rated at 240) I know its only 10 hp, but every bit counts I guess.

If you look at the specifications page of the BMW NA website it gives you some useful information. The 528i engine has a 3.3 inch bore and a 3.5 inch stroke. The 128i is 3.35 inch bore and 3.46 inch stroke. Longer stroke engines typically have higher torque. The 528i only goes up 10hp but 30 ft-lbs. Seems consistent with the displacement change plus some reprogramming. Doesn't seem like you could implement the change.
