Character

S63

"F10/F90 M5 engine. Hot-V turbo layout. More reliable than N63 base engine due to stronger internals. Rod bearing concern on early units. Oil consumption. Expensive maintenance but less catastrophic than N63."

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."
