BMW has just unveiled the highly anticipated 2025 M5, and while the headlines are buzzing about its мощный twin-turbo V-8 hybrid powertrain churning out a staggering 717 horsepower, there’s another figure that’s grabbing attention – its weight. The new M5 tips the scales at a hefty 5,390 pounds. This figure isn’t just substantial for a sports sedan; it’s outright surprising, placing it in the weight category of some large SUVs and even pickup trucks.
To put this figure into perspective, the 2025 Bmw M5 Weight surpasses that of several notable vehicles, including:
- 2022 Chevrolet Tahoe 2WD (5,356 lbs)
- 2024 Ford F-150 Supercrew 4WD (4,941 lbs)
- 2024 Lucid Air Sapphire (5,336 lbs)
- 2023 Mercedes Maybach S-Class (5,346 lbs)
- 2024 Range Rover Sport (5,090 lbs)
This considerable curb weight marks a significant departure for the M5, a model traditionally celebrated for its agility and performance. Compared to its predecessor, the new M5 is not only heavier – it’s also, on paper, slightly slower. BMW states a 0-60 mph sprint time of 3.5 seconds for the 2025 model, a shade slower than the previous generation’s 3.2 seconds. Furthermore, the power-to-weight ratio has taken a hit, as the new car carries over 1,000 pounds more than the outgoing F90 M5.
Looking at the historical trend of BMW M5 weight across generations, the increase is even more striking. The evolution of the M5 has generally seen gradual weight increases. For instance, the E39 M5 was only marginally heavier than the E34. Remarkably, the F90 generation prior to this new model actually managed to shed 17 pounds compared to the F10. This historical context underscores just how jarring the sudden half-ton weight gain in the 2025 M5 truly is.

In a surprising turn of events, the BMW M5, once a benchmark for lighter and more nimble performance sedans, now finds itself out-weighed by vehicles it once outclassed in this metric. Competitors previously considered heavier, such as the Dodge Charger Hellcat, now appear comparatively lighter. The outgoing Dodge Charger Hellcat weighs in at 4,570 pounds, a substantial 820 pounds less than the new M5. Even the Cadillac CT5-V Blackwing, a direct American rival to the M5, boasts a significantly lower weight, being a staggering 1,267 pounds lighter. This weight disparity is particularly notable considering the CT5’s wheelbase is only about two inches different from the 5 Series, indicating that size alone isn’t the primary factor in this weight difference.
Adding to the intrigue, even BMW’s own fully electric i5 outperforms the new M5 in terms of weight. The BMW i5 M60, a dual-motor electric vehicle packed with over 80 kWh of battery capacity, is actually lighter than the M5 by 143 pounds. This comparison highlights the considerable weight added by the M5’s hybrid system, challenging the notion that electrification invariably leads to heavier vehicles.
The reasons behind this substantial weight increase in the 2025 BMW M5 likely stem from a combination of factors. European emissions regulations, BMW’s platform-sharing electrification strategy, and the complexity of integrating a hybrid powertrain into an existing platform all contribute to the added mass. However, from a technological standpoint, it’s clear that hybrid vehicles don’t inherently need to be this heavy.
The Corvette E-Ray, for example, demonstrates that performance hybrids can be lightweight, utilizing a smaller 1.9-kWh battery pack to achieve 160 horsepower while maintaining a weight close to the BMW M2. Furthermore, the M5’s plug-in hybrid nature, with its larger 18.6-kWh battery and onboard charger, adds further weight that might be unnecessary for a performance-focused vehicle, especially considering the limited electric range benefit in a car like the M5. While European regulations are indeed stringent, the question arises whether BMW’s flagship performance sedan should bear such a significant weight penalty in pursuit of compliance.
BMW’s chosen approach of integrating an electric motor into a conventional all-wheel-drive system, complete with an automatic transmission, transfer case, and front driveshaft, undoubtedly has advantages in terms of platform commonality and development efficiency. However, optimizing for weight savings doesn’t appear to have been a primary focus. The 2025 M5 essentially adds an electric motor and battery pack on top of an already complex and robust drivetrain, inevitably leading to increased weight.
While the engineering and regulatory pressures faced by BMW are complex, from a customer perspective, the bottom line is the tangible weight of the car. Regardless of its technological prowess and driving dynamics – which by all accounts seem impressive – the 2025 BMW M5 will always carry the asterisk of weighing more than a full-size Ford F-150. In a landscape increasingly populated by lighter electric performance cars boasting four-figure horsepower, the weight of the new M5 raises questions about the long-term viability of combustion engines, even in BMW’s revered M cars.
The automotive world once witnessed brands vying to dethrone the BMW 3 and 5 Series, particularly the iconic M3 and M5. Yet, none truly succeeded in consistently overshadowing the Bavarian benchmark. Ironically, it seems that the most significant challenge to the M5’s dominance may have come from within, with a substantial weight increase that alters its fundamental character and competitive positioning.
