Best & Worst Engines
Thin-Data Summary
“The S85B50 5.0‑litre V10 -BMW's only production V10 and a motorsport‑derived masterpiece -produces 507 hp at 7,750 rpm with an 8,250 rpm redline. It is one of the greatest naturally aspirated engines ever built, but reliability is a significant concern. Rod bearing wear is the defining weakness -premature wear can lead to catastrophic bottom‑end failure. Throttle actuator failure is also common. The engine is fundamentally robust for a high‑performance V10, but owners must budget for preventative rod bearing replacement (typically £1,200–£2,500). Buyers should prioritise a well‑maintained example with documented rod bearing history.”
Who it's for:
BMW M6 E63/E64 -Ownership Economics
The M6 E63/E64 rule
A £8,000–£15,000 S85 recon against a £15,000–£60,000 M6 sits at 13–100% of the car's value. On a sub‑£20,000 M6, that approaches our 70% BMW threshold -we'll honestly tell you to walk away. Against a well‑kept £40,000+ example, the same recon drops to a routine 20–40% -a repair decision, not a financial one. Value the car first. The rod bearing is the single biggest risk -budget for preventative work (£1,200–£2,500) on any car.
