The 2025 BMW M5 has been making headlines not just for its impressive 717-horsepower rating from its twin-turbo 4.4-liter V-8 hybrid powertrain but also for its substantial curb weight of 5390 pounds. In a recent interview with Top Gear, Frank van Meel, the head of BMW’s M division, revealed that the hybrid system accounts for a significant portion of that weight, with the 14.8-kWh lithium-ion battery alone weighing 882 pounds.
While some may question the decision to add such a heavy battery to the M5, BMW defended the move by emphasizing the performance gains that come with a plug-in hybrid system. Van Meel pointed out that a standard hybrid system would already add between 330 and 440 pounds, so opting for a plug-in system offers even better performance benefits.
One of the key advantages of the plug-in hybrid approach is the ability for the M5 to travel an estimated 25 miles in all-electric mode. This feature not only aligns with the growing trend of zero-emissions zones in major cities but also showcases BMW’s commitment to embracing electrification while delivering a high-performance driving experience.
Despite the weight increase, van Meel explained that BMW strategically placed the battery in the floor of the car to optimize the vehicle’s balance and handling. By lowering the center of gravity, the M5 aims to maintain its agility and dynamic driving characteristics, even with the added weight of the battery.
In response to questions about the possibility of an all-electric M5 or downsizing the engine, van Meel emphasized the importance of preserving the V-8 engine for its emotional appeal and compact design. While other manufacturers may be exploring alternative powertrains, BMW believes that the V-8 engine remains the best choice for delivering both performance and character in the M5.
Overall, the decision to incorporate a plug-in hybrid system in the 2025 BMW M5 represents a strategic move by BMW to leverage electrification technology for enhanced performance capabilities. While the weight increase may raise concerns among enthusiasts, the M division is confident that the M5 will continue to deliver a thrilling driving experience that blends power, efficiency, and innovation. As we anticipate the opportunity to test drive the latest M5, it will be interesting to see how the added weight influences the car’s overall performance on the road.
