Character

S65

"E90/E92 M3. High-revving 8,300rpm V8. Rod bearing failure is THE concern — can destroy engine without warning. Throttle actuators fail. Amazing driving experience but preventive rod bearings are mandatory."

B58

"Possibly BMWs best engine ever. Forged internals, insane tuning (600hp+). 300k+ km."
