The 2025 BMW M5 Is Now a 717-Horsepower, Plug-in Hybrid Beast

As you'd expect, it picks up quite a bit of heft with that big battery pack onboard

Meet the most powerful BMW M5 yet.

Following up the rest of the 5 Series range, here’s the most anticipated variant of them all: the new M5. Previous generations including the outgoing F90 were powerhouses among midsize sports sedans, and this latest G90 isn’t breaking with that tradition. What it is breaking with, though, is the notion of your next M car being powered by internal combustion alone. Enthusiasts can take a sigh of relief in that this new car isn’t completely electric — the twin-turbo V8 is still very much part of the equation — but there is an electrified plug-in hybrid piece to the equation this time around.

Specifically, the 2025 BMW M5 is still rocking a 4.4-liter S68 engine pumping out 577 horsepower all on its own. Coupe to that an electric motor integrated into the 8-speed automatic transmission, though, and total output jumps to a meaty 717 horsepower and 738 lb-ft of torque. If that sort of grunt sounds familiar, you’re not wrong: It’s a similar setup to the BMW XM Label, although this car puts out slightly less horsepower. That said, it’s still plenty to rocket this 5,390-pound leviathan of a sedan to 60 mph in just 3.4 seconds. Top speed? Well, that sits at a cool 190 mph, provided (as always) you spec the optional M Driver’s package. Peak torque for this new M5 comes on at just 1,800 RPM, and hangs in until 5,400 RPM, so you’ll definitely have plenty of shove when you put your foot down, even with this new M5’s half-ton weight gain over the last model.

On the electrified side of the powertrain, the 2025 BMW M5 gets a 14.8-kWh (usable capacity) battery. Beyond churning out heaps of torque, that obviously allows some degree of all-electric driving, and this new G90 model does have an Electric drive mode. However, the automaker is plainly focused on the PHEV setup aiding performance, as the company hypes up its new “Boost Control” function. Enabling that feature summons all the power the car’s computers can muster for a “nearly instantaneous burst of speed” anywhere between 20 and 90 mph. Pull the left-hand shift paddle for more than a second, and all the powertrain and chassis settings will go into their sportiest modes. From there, stamp your right foot, and the M5 “responds with immediate and truly ferocious acceleration.” In other words, all hell will break loose — and that does sound like fun.

The M5 is still a different animal above the rest of the 5 Series lineup.

Now that we’ve seen the other new 5 Series models, the 2025 BMW M5 does follow its siblings in terms of general layout, including the dual screens for the instrument cluster and infotainment system. There are still plenty of special M-only touches, though, like the center stripe on the flat-bottomed steering wheel and the continuation of the two M mode buttons. The M5 also gets some special aesthetic touches on the IP with the signature red and blue colors, as well as a red starter button on the center console and the M logo outline in the iDrive controller knob.

As you’d rightly expect for a sports sedan costing six figures, BMW’s engineers have factored in a host of M5-specfic changes as far as driving dynamics, beyond the powertrain itself. This new G90 generation gets its own suspension setup and tuning, as well as adaptive dampers and massive 285/40ZR20 wheels and tires up front, with 295/35ZR21s out back. You need a lot of rubber to corner with all that power and heft, after all, so it only makes sense that the new M5 also packs six-piston front brake calipers, while it uses single-piston floating calipers at the rear. They don’t come as standard equipment, but yes, you can get carbon ceramic brakes as an option.

2025 BMW M5 models start at $120,675 including destination, so you’ll have to have some serious cheddar to pick one up. If you have the means, though, they’ll go on sale in the fall.
