Character

N63TU (N63B44O1/O2/T3)

"The updated hot-V V8 (from 2012-2013) with Valvetronic, forged internals, new valve stem seals and a second coolant pump: 550i F10 from July 2013, 750i, 650i, X5/X6 50i, then M550i, 750i G11, M850i and X5/X7 M50i. Clearly better than the original N63, but it still burns oil (its own US settlement) and chains and injectors are not immune. Budget accordingly."

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."
