BMW’s B58 3 litre straight 6 engine is an updated version of its predecessor the N55 engine. Both engines retain the same 500c per cylinder layout with a slightly under-square design, the B58 moves to an 82mm bore and a 94.6mm stroke while the N55 has an 84mm bore with an 89.6mm stroke. The B58 is design-wise identical to the B38 and B48 engine.

Turbo designs stay similar with a single twin-scroll turbocharger. However, some variants of the B58 feature a “mani head” design which incorporates the exhaust manifold in the head. TU models of this engine fitted to LCI models and the Z4M and A90 Supra featured an updated design including a higher flow fuel system. The B58 engine is a superb platform with great performance increases with relatively few supporting modifications needed. Over 470BHP can be achieved on a virtually standard engine.
