The M5 Competition uses a 4.4 L twin-turbocharged V8 petrol engine that produces 617 hp and drives all four wheels.
The F10 M5 is generally reliable but can develop oil leaks. The E60 M5’s V10 suffers from rod-bearing wear and VANOS problems.
Having an engine replaced usually requires 12–18 hours of labour, so the job typically takes one to two days.
With proper maintenance and regular oil changes, a BMW M5 engine can last around 150,000 miles.
The amount a BMW M5 can cost to replace or rebuild depends on engine type and labour. A used or refurbished engine offers significant savings compared with buying new, and labour is usually the largest part of the bill.
If the timing chain fails, pistons can strike open valves, bending or breaking them and damaging pistons and cylinder walls.
Later M5 models improved reliability. The F10 M5’s V8 twin turbo resolved many rod-bearing and VANOS problems, though turbo wear and oil consumption can still occur.
Many enthusiasts consider the E39 M5 with the naturally aspirated S62 V8 to be the most reliable because it lacks complex turbocharging.
BMW has announced that the 2025 M5 will pair a 4.4 L V8 with an electric motor for a hybrid powertrain producing 727 hp and 1000 Nm of torque.
BMW recommends a 10W-60 full-synthetic oil, such as Shell M TwinPower Turbo 10W60, for the E60 M5’s S85 V10 engine.
Generations vary: the E39 uses a 4.9 L S62 V8, the E60 uses a 5.0 L S85 V10, the F10 and BMW F90 use 4.4 L twin-turbo V8 engines, and the 2025 M5 will feature a hybrid 4.4 L V8.
