2028 BMW M5 Exhaust Sound Will Surprise You

The next evolution of the BMW M5 is shaping up to be good news for performance enthusiasts. While the refreshed 2028 model is expected to receive updated styling and new technology, the heart of the car is expected to remain the same. That means the familiar 4.4 liter twin turbocharged V8 engine will continue to work alongside a powerful electric motor, creating one of the most capable performance sedans BMW has ever produced.

The current system delivers an impressive 717 horsepower and 738 pound feet of torque, and there is no strong evidence that BMW plans to make major power increases for the facelift. Instead, engineers are expected to focus on refining how the power is delivered. Improvements to the software, transmission calibration, and electric motor response could make the car feel even quicker in everyday driving while maintaining its explosive acceleration.

One area many enthusiasts are watching closely is the exhaust sound. As emissions regulations become stricter around the world, manufacturers continue searching for ways to preserve the emotional character of their performance cars. Early prototype videos suggest the refreshed M5 still produces the deep, aggressive rumble expected from a twin turbocharged V8. Under hard acceleration, the engine delivers a rich growl that builds into a powerful roar, reminding drivers that this is still a true M car despite its hybrid technology.

The electric motor adds instant torque from a standstill, helping the M5 launch with remarkable force before the V8 takes over with a relentless surge of power. The combination creates smooth yet thrilling acceleration that makes highway passing and spirited driving feel effortless. It is a balance of traditional performance and modern electrification that few competitors can currently match.

Although the facelift will likely focus more on styling than mechanical changes, the engine remains the star of the show. For many enthusiasts, hearing a twin turbocharged V8 continue into the next chapter of the M5 story is just as exciting as seeing the updated exterior. If this truly becomes one of the final V8 powered M5 models, it could also become one of the most memorable.
