The E39 540i

Engine

The BMW E39 540i was powered by the M62B44 and later the M62TUB44, both 4.4-liter naturally aspirated V8s. These engines made the 540i the most powerful non-M model in the E39 lineup, offering a balance of luxury, refinement, and high-performance.

The pre-facelift 540i (1996–1998) featured the M62B44, a non-VANOS engine with a simpler design and strong reliability. The post-facelift (1998–2003) introduced the M62TUB44, which included single VANOS (on the intake cam) for better low-end torque and improved efficiency.

Paired with either a 6-speed manual (rare and desirable) or a 5-speed automatic, the 540i delivered a grand touring experience, often considered the best alternative to the M5.


Performance

Both versions of the M62B44 delivered strong performance, but the facelifted M62TUB44 had improved low-end response and efficiency due to the VANOS system.

Pre-Facelift (M62B44 – 1996-1998)

  • Power Output: 286 hp (210 kW) @ 5,700 rpm
  • Torque: 420 Nm (310 lb-ft) @ 3,900 rpm
  • 0-100 km/h (0-62 mph): ~6.2 seconds (manual) / ~6.4 seconds (automatic)
  • Top Speed: 250 km/h (155 mph)

Post-Facelift (M62TUB44 – 1998-2003)

  • Power Output: 286 hp (210 kW) @ 5,400 rpm
  • Torque: 440 Nm (325 lb-ft) @ 3,600 rpm
  • 0-100 km/h (0-62 mph): ~6.0 seconds (manual) / ~6.2 seconds (automatic)
  • Top Speed: 250 km/h (155 mph)

Fuel Efficiency

While the 540i was a performance-oriented V8, it still maintained reasonable fuel economy for its class. However, its power and weight meant higher fuel consumption compared to inline-six models. But, after all, this car really embodies the smiles per galon principle.

Fuel Consumption:

  • Combined: ~11.0–12.5 liters per 100 km (19–22 mpg)
  • Urban: ~15.0–16.0 liters per 100 km (14–16 mpg)
  • Extra-Urban: ~8.0–9.5 liters per 100 km (25–29 mpg)
  • Fuel Tank Capacity: 70 liters (18.5 gallons)


Reliability

The M62 engine family was robust, but the post-facelift version had additional complexity due to VANOS. Common issues include:

  • Timing chain guides – A weak point that requires replacement around 200,000 km.
  • VANOS wear (1998+ models) – Fails over time, leading to power loss and rough idle.
  • Cooling system – Weak points include water pumps, radiators, and expansion tanks.
  • Oil leaks – Valve cover gaskets, timing covers, and rear main seals are prone to leaks.
