The 2025 M5 packs a reworked 4.4-liter twin-turbo V8 engine that, by itself, puts out 600 horsepower at 6,000 rpm and 750 Nm from 1,800 to 5,600 rpm. This is mated to an 8-speed M automatic transmission driving all four wheels via the M xDrive all-wheel drive system. Specifically, for the G90 M5 though, there’s also an integrated electric motor that puts out 197 horsepower and 280 Nm for a grand total of 727 horsepower and 1,000 Nm of torque. An underfloor 22.1-kWh (18.6 kWh net) lithium-ion battery provides up to 69 kilometers of all-electric range at speeds of up to 140 km/h and this one can be charged via an AC input (7.4 kW maximum).

Stopping the all-new M5 are beefy M Compound brakes with 410 mm discs and six-piston fixed calipers at the front and 398 mm single-piston floating calipers out back. M Carbon ceramic brakes are also available as an option.

Sadly, despite the bonkers numbers, the G90 is slower than the F90 that it replaces. The all-new M5 now takes 3.5 seconds to reach 100 km/h—a tenth slower than the previous M5 (two-tenths versus the M5 Competition). This is down to a less-than-ideal power-to-weight ratio. The electric motor, batteries, and related hardware means the G90 M5 has put on some weight. But no one expected it to weigh in at 2,510 kilograms—about 570 kilograms heavier than the previous F90 M5. This puts this sports sedan in the same league as the Chevrolet Tahoe, Range Rover Sport, and even Ford F-150. The all-new M5 makes around 294 horsepower per ton versus 312 horsepower per ton in the non-Competition F90 M5 and 330 horsepower per ton in the F90 M5 Competition.

Design-wise, the M5 looks the part with its aggressive-looking wheel arches that bump up the width by 75 mm at the front and 48 mm at the back. The front clip is like the regular 5 Series with its partially closed-off kidney grille, but here, it’s finished in high-gloss black. That said, it does sport larger air intakes similar to its M Hybrid V8 racing car. Over to the sides, it rides on staggered wheels measuring 20 inches at the front and 21 inches at the back. The M5 logo also replaces the “5” logo on the C-pillar. At the back, there’s a rear spoiler, a two-section diffuser, and tailpipes finished in black chrome.

Inside, the M5 sticks to the regular 5 Series’ dashboard layout, but gets dressed up in appropriate M wear including a new steering wheel (with red center marker) and dedicated M buttons for personalized drive modes. The Curved Display with its 12.3-inch digital instrument cluster and 14.9-inch central touchscreen also gets M-specific touches, as does the expansive Interaction Bar ambient lighting system and head-up display.

The all-new M5 will start production in July with global sales starting in November. A Touring (wagon) version will also be introduced towards the end of this year.
