What is the engine model of the BMW M5?

[AlyssaLee]

The engine model of the BMW M5 is S63B44B. The function of the engine is to convert the thermal energy of gasoline or diesel into mechanical energy by burning the fuel in a sealed cylinder, causing the gas to expand and push the pistons to perform work. Taking the 2021 BMW M5 as an example, its body structure is a four-door, five-seater sedan with body dimensions of 4989mm in length, 1903mm in width, and 1502mm in height, with a wheelbase of 2982mm. The 2021 BMW M5 features a double-wishbone independent front suspension and a multi-link independent rear suspension. It is equipped with a twin-turbocharged engine, delivering a maximum horsepower of 600ps, a maximum power of 441kw, and a maximum torque of 750nm, paired with an 8-speed automatic transmission with manual shift mode.

As a car enthusiast, I'm fascinated by the evolution of the M5's engines. The first-generation E34 used the S38 inline-six 3.6L naturally aspirated engine, later replaced by the S62 5.0L V8 in the E39. What really excites me is the S85B50 from the E60 era - the roar of that 5.0L V10 is absolutely incredible! The current F90 M5 has switched to the S63B44T4, a 4.4L V8 twin-turbo that accelerates faster with 0-100km/h in just over 3 seconds, but somehow lacks the purity of the naturally aspirated era. Every time I hear the sound of that old V10, it still gives me goosebumps.

Recently disassembled the F90 M5's engine, codenamed S63B44T4, which is incredibly powerful. The 4.4-liter twin-turbo V8 features a cross-bank design for faster turbo response, with the Competition version pushing out 625 horsepower. This engine is equipped with high-pressure direct injection technology, paired with an 8-speed transmission and all-wheel drive system, making it comfortable even for daily driving. The exhaust crackles during cold starts, and a deep press of the throttle instantly pins you to the seat. Although the compact design makes maintenance a bit tricky, the performance is truly unmatched.

Having worked on cars for over a decade, I frequently encounter the S63 series engines in M5 models. This 4.4T V8 turbocharged engine tends to develop some minor issues: the turbo cooling pipes are prone to leaks, the high-pressure fuel pump may suddenly fail, and ignition coil problems can cause cylinder misfires and vibrations. Always remind owners to use fully synthetic 0W-40 oil and replace spark plugs every 20,000 kilometers. Just last week, I dealt with a case of abnormal water temperature – upon disassembly, we found the water pump seal had aged. These precision engines require diligent maintenance.
