The fourth-generation M5 remains the only V10-powered M5 and the world's first production saloon with a V10 engine — a Formula 1-inspired unit conceived when BMW was deep in grand prix.

Europe also got an E61 Touring; North America uniquely got a six-speed manual. Its high-revving character and analogue-adjacent drama have made it a modern-classic favourite despite a fearsome running-cost reputation.
The only V10 M5 and the first V10 production saloon — a clear historical hook underwriting its modern-classic status.
