Character

B37

"3-cylinder modular diesel. Shared architecture with B47/B57. Quiet for a 3-cyl. Limited production span. No major known issues — too few on road for long-term data. Timing chain is front-mounted (good)."

M57

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