Character

N63

"Hot-V design cooks turbos and injectors between cylinder banks. Oil consumption, coolant leaks, injector failure. N63TU (2012+) improved but still problematic. Called 'hot vee from hell' by BMW techs."

M57

"Legendary diesel six. Powered E46 330d to E90 335d. Smooth, torquey, reliable. Swirl flaps and turbo actuator at high mileage."
