| This technological masterpiece does not only sport the same number of cylinders as its Formula 1 BMW WilliamsF1 racing counterpart, but also shares its high-revving concept. As is the case with all high-performance normally aspirated engines made by BMW M, this power unit generates enormous pulling force over the entire speed range. |

| A masterpiece in engine construction BMW, one of the leaders in engine construction, has made a name for itself primarily as a manufacturer of inline engines. The two five-cylinder banks of the V10 are arranged at an angle of 90กใ to achieve a mass balance of the crankshaft drive, which is optimized for low vibration and increased comfort. For reasons of stiffness, that is due to the high loads resulting from combustion pressure, engine speed and vibrations, a bedplate design has been chosen for the crankcase. For an optimum alignment of the crankshaft, grey-cast iron inserts have been integrated into the aluminium bedplate, which also serve to enhance acoustics, increase vibrational comfort and ensure a high oil supply rate. The extremely stiff crankshaft is supported by six bearings. In the new M5, it is the first time that BMW has used a bedplate design for a production V engine. |
