The E39 M5

Engine

The E39 M5 was the most powerful, most expensive, and most desirable model in the E39 lineup. Powered by the legendary S62B50, a 5.0-liter naturally aspirated V8, this was the first M5 to feature a V8 engine, marking a departure from the inline-six powerplants of previous generations.

The S62 was a high-performance evolution of the M62 engine, featuring individual throttle bodies (ITBs), double VANOS (on both intake and exhaust cams), and a higher redline of 7,000 rpm. These upgrades gave the E39 M5 a raw, high-revving character, setting it apart from any other E39.

It was paired exclusively with a 6-speed manual transmission, reinforcing its driver-focused nature. With aggressive styling, an M-tuned suspension, and a luxurious yet sporty interior, the E39 M5 was the definitive sports sedan of its time.


Performance – The Most Powerful E39

The S62B50 was the most powerful engine ever fitted to an E39, outclassing the 540i and every other model in the range.

  • Power Output: 400 hp (294 kW) @ 6,600 rpm
  • Torque: 500 Nm (369 lb-ft) @ 3,800 rpm
  • 0-100 km/h (0-62 mph): 4.8 seconds
  • Top Speed: 250 km/h (155 mph) (electronically limited) (Over 290 km/h with limiter removed)

The E39 M5's acceleration, power delivery, and high-speed capabilities made it one of the fastest sedans of its era, and it remains a benchmark for sports sedans today.

Reliability – Costs of a High-Performance Machine

The S62 engine was a masterpiece of engineering, but its complexity meant higher maintenance demands compared to the standard E39 models.

  • Rod bearings – Can wear prematurely, especially with aggressive driving.
  • VANOS issues – The double VANOS system is prone to seal failure, causing performance loss.
  • Throttle body actuators – The ITB system is complex, and failures can be costly.
  • Cooling system – Like other E39s, radiators, water pumps, and expansion tanks can fail.

The E39 M5 demands meticulous maintenance, but when properly cared for, it remains one of the greatest sports sedans ever built.


The Most Desirable E39 – A True Gem

The E39 M5 is widely regarded as one of BMW's best M cars ever made, thanks to its perfect balance of power, handling, and daily usability.

  • The most powerful and expensive E39 – It stood far above the 540i in both performance and price.
  • One of the best sports sedans of all time – Many enthusiasts and journalists still consider it the greatest M5 ever made.
  • A future classic – With prices rising rapidly, the E39 M5 is one of the most sought-after BMWs of its era.

For those who want the ultimate E39 experience, nothing comes close to the M5.
