The new M5 is heavier than a Chevrolet Tahoe. What is BMW doing?

BMW has just launched the new 2025 M5: a hybrid sports sedan with twin turbocharger, V8 and all-wheel drive developing 717 horsepower. It also weighs 5,390 pounds, making it heavier than some electric sedans, SUVs, and even a pickup truck.

This list includes:

  • 2022 Chevrolet Tahoe 2WD (5,356 lbs)
  • 2024 Ford F-150 Supercrew 4WD (4,941 lbs)
  • 2024 Lucid Air Sapphire (5,336 pounds)
  • 2023 Mercedes Maybach S-Class (5,346 lbs)
  • 2024 Range Rover Sport (5,090 pounds)

It’s an absolute monster in terms of curb weight, and compared to the previous generation it’s slightly Slow down on paper. BMW says its sprint to 60 miles per hour takes 3.5 seconds, compared to 3.2 seconds for the old car. Its power-to-weight ratio is also worse than the old car’s: It weighs more than 1,000 pounds more than the outgoing M5.

It’s telling to track this sudden increase in weight in the context of all other M5s. Referring to the chart below, you can see that the trend has been relatively gradual. The E39 M5, for example, weighed only 110 pounds more than the E34. The last generation before the new M5, the F90, actually lost 17 pounds compared to the old F10.

This makes the sudden addition of half a ton even more shocking.

The new M5 is heavier than a Chevrolet Tahoe.  What is BMW doing?

The roles have reversed in the face of American car competition. Vehicles derided for being heavier and lazier than the M5 are now welterweights in comparison. The outgoing Dodge Charger Hellcat weighed 4,570 pounds, or 820 pounds less. The latest CT5-V Blackwing, the M5’s direct American competitor, is lighter by a jaw-dropping 1,267 pounds. It’s not even like the M5 is a much bigger car. The CT5’s wheelbase is less than two inches from that of the 5 Series.

Unfortunately, even the new all-electric i5 comes out on top. The i5 M60, a dual-motor BEV with a battery capacity of more than 80.0 kilowatt hours, weighs 143 pounds less.

We could delve into European emissions regulations, BMW’s platform-sharing electrification strategy and other influences to find out exactly what contributed to this huge weight gain. However, the fact is that we know that it does not have to be this way from a technological point of view.

Hybrids don’t need to be heavy; You don’t need a raw 18.6 kWh battery to get 190 horsepower. The Corvette E-Ray uses a 1.9 kWh raw pack to get 160 hp (and it’s only slightly heavier than the latest BMW M2). Hybrids also don’t have to be plug-in. The added weight of an onboard charger doesn’t help the mass – and remind me again why 25+ miles of electric range is needed in an M5? European emissions regulations are stricter than their American counterparts, of course, but the latest car to take the hit in BMW’s lineup should be the company’s hallowed performance sedans.

A battery with high power density, not necessarily high energy density, is how you run a high-performance mild hybrid car. Porsche continues to prove it with the new 911 GTS. BMW has not taken this route. The company’s strategy of integrating an engine into an existing combustion drivetrain certainly has benefits across its lineup, but weight saving isn’t one of them. The M5 has a conventional all-wheel drive system with an automatic transmission, transfer case, front driveshaft and more. They simply installed an electric motor on top.

We do not know all of BMW’s technical and regulatory constraints. From the customer’s perspective, however, these elements are almost invisible. The M5, as competent as it is – and it appears to be very competent – ​​will never escape the fact that it weighs more than a full-size F-150. Compared to today’s lighter, high-performance electric cars boasting four-digit horsepower, one wonders how much longer BMW’s M cars will even have a combustion engine.

Remember when brands like Audi, Cadillac, Jaguar and Mercedes-Benz were all looking to demolish the 3 and 5 Series, especially the M3 and M5? None of them ever really did. Their respective competitors were almost always in the shadow of the Bavarian giant.

Turns out all they had to do was sit and wait.
