BMW M5 E60 V10

The BMW E60 M5 was the most audacious M car ever conceived. While every previous M5 had used variations of inline-six or V8 engines, BMW M Division made the extraordinary decision to install a V10 — derived from the engine that powered their Formula 1 cars — into the fifth-generation 5 Series. The result was a sedan that could rev to 8,250 rpm, produce 507 horsepower, and sound like no other production car on the road.

The S85 engine was a masterwork of engineering extravagance. Its 5.0-liter capacity was spread across ten cylinders, each with four valves, giving the engine forty valves in total. Individual throttle bodies — one per cylinder — ensured instantaneous response to driver inputs. The block was cast aluminum with a bedplate construction for rigidity, and the crankshaft used a 72-degree V-angle optimized for smoothness. BMW claimed the engine shared significant DNA with the P84 V10 that powered their Formula 1 cars, and while the specifics were debated, the character was unmistakably race-bred.

The engine's personality was defined by its top end. Below 4,000 rpm, the S85 was unremarkable — smooth and refined but not exceptionally powerful. Above 4,000 rpm, a transformation occurred. The exhaust note hardened, the engine note rose in pitch, and the power delivery became increasingly urgent as the tachometer swept toward the 8,250 rpm redline. This top-end rush, accompanied by one of the most spine-tingling exhaust notes in automotive history, was addictive — drivers found themselves shifting later and later, chasing the visceral thrill of a V10 at full cry.

The M Button on the steering wheel offered three engine maps: P400 (limited to 400 hp for daily driving), P500 (full 507 hp), and a sport setting that sharpened throttle response. This programmable power delivery acknowledged that 507 horsepower in a rear-wheel-drive sedan required some discretion for everyday use.

The E60 M5 was primarily offered with the SMG III automated manual gearbox — a single-clutch automated system that BMW claimed offered the convenience of an automatic with the performance of a manual. In practice, the SMG was controversial: brilliant in aggressive driving modes where its brutal shift speed was genuinely impressive, but jerky and unrefined at low speeds and in traffic. A six-speed manual was eventually offered for the North American market and remains the transmission overwhelmingly preferred by enthusiasts today.

The chassis was comprehensively engineered for the task. Double-wishbone front suspension, integral multi-link rear, adaptive dampers, dynamic stability control with M Dynamic Mode, and a variable-ratio steering rack created a car that could handle the V10's output with composure. The brakes — massive cross-drilled discs with six-piston front calipers — provided stopping power commensurate with the acceleration.

The E60 M5 was always a car of extremes — extreme power, extreme complexity, extreme running costs. The S85 engine, while magnificent when healthy, proved expensive to maintain and could suffer significant failures. But for those who accepted the costs and compromises, the E60 M5 offered a driving experience that was genuinely unique — no other sedan has ever used a naturally aspirated V10, and almost certainly none ever will again.
