Character
S68
"Latest M V8. XM/M5 G70. Cross-plane crank, 48V mild hybrid on some variants. Too new for long-term data but BMW learned from N63/S63 mistakes. Front-accessible turbos. Early data positive."
M57
"Legendary diesel six. Powered E46 330d to E90 335d. Smooth, torquey, reliable. Swirl flaps and turbo actuator at high mileage."
