The B58 comes in middle output and high output variants.

you have the 321hp variant seen in the 340i, 440i, 740i
you have the 335hp variant in our M140i, M240i, 540i
you have the 382hp variant used in the Z4 M40i, new Supra

BMW states that the variant in the M240i produces 335-340hp, however this number in actual is higher. not only that, but the B58 is an engine built to handle significantly more power than what comes out the factory.

beast of an motor.
