The BMW M52 is a straight-6 DOHC piston engine which replaced the M50. The M52 was produced from 1994-2001. Compared with its M50 predecessor, the M52 uses an aluminium block. However, North American models used iron blocks instead (except in the Z3), therefore the North American M52 is more akin to the M50TU. In 1999, the M52TU ("technical update") was released, upgrading the variable valve timing to also adjust the exhaust camshafts (called "dual VANOS" by BMW), adding electronic throttle control (which uses a throttle cable as backup)[1] and a dual length intake manifold (called "DISA" by BMW). urmatorul motor M54B... este EURO4.
