Character

M43

"Cast iron block workhorse. Timing chain not belt (unlike M40). Simple, cheap to maintain. 300k+ km common. Low power is the only complaint."

M50

"Cast iron block legend. One of BMW's most reliable ever. M50TU added single VANOS. Strong internals handle 300k+ km. Cooling plastics only weakness."
