The 2025 BMW M8 delivers 617 horsepower from its twin-turbo V8, sprints to 60 mph in just 2.5 seconds (per Car and Driver testing), and combines supercar performance with genuine grand touring comfort Available as a coupe, convertible, or four-door Gran Coupe, the M8 starts at $140,975 and represents the pinnacle of BMW's 8 Series lineup This is the final year for the coupe variant, making it a collector's consideration for enthusiasts
Overview: Why the M8 Matters
The BMW M8 occupies a unique space in the performance car market, blending the comfort of a luxury grand tourer with acceleration that embarrasses many dedicated sports cars. Where the BMW M5 prioritizes practicality with four doors, the M8 focuses on style and presence while still offering usable back seats
Unlike mid-engine supercars, the M8 offers a front-engine layout that prioritizes stability at high speeds and provides trunk space for weekend getaways. The car feels milled from a single chunk of metal, with a solidity that explains its 4,251-pound curb weight but also contributes to its planted, confident road manners For those seeking a similar experience in a more practical package, the BMW 8 Series Gran Coupe offers four-door convenience with slightly less aggressive tuning.

Design and Practicality
Exterior
The M8's styling strikes a balance between understated elegance and muscular presence. Quad exhaust tips, flared fenders, and aggressive air intakes distinguish it from the standard 8 Series, while the overall silhouette remains classic GT proportions The convertible adds open-air appeal for approximately $10,000 more, while the Gran Coupe stretches the roofline for improved rear-seat access
Interior
Inside, the M8 delivers on its luxury promise with rich, beautifully stitched leather and elegant ornamental trim The optional Merino leather two-tone interiors elevate the cabin further. Standard equipment includes:
12.1-inch digital gauge cluster
12.3-inch central touchscreen with iDrive
Heated and ventilated front seats
Wireless charging
Soft-close doors
16-speaker Harman Kardon audio system
Rear seats are present but best reserved for toddlers and small packages. Legroom measures just 29.5 inches, making extended trips uncomfortable for adult passengers The trunk accommodates approximately five carry-on suitcases in the coupe variant
Performance and Efficiency
Powertrain
At the heart of the M8 sits BMW's S63 twin-turbocharged 4.4-liter V8, producing 617 horsepower and 553 lb-ft of torque An eight-speed automatic transmission routes power to all four wheels through BMW's xDrive all-wheel-drive system. Crucially, drivers can disengage the front axle in 2WD mode, sending all torque to the rear for a dramatically different driving experience
Car and Driver recorded a 0-60 mph time of 2.5 seconds and a quarter-mile of 10.7 seconds at 129 mph—matching a Chevrolet Corvette Z06 and outpacing a Ferrari F8 Tributo to 60 mph The car generates over 1.0 g of lateral grip in corners, defying its substantial weight
Driving Experience
The M8 excels as a high-speed cruiser. In Comfort mode, the ride remains firm but livable for daily driving. Track mode transforms the car into a focused machine with taut suspension and sharper responses Reviewers note some disappointments: the exhaust note is muted for a 617-hp V8, steering feedback is minimal through the thick wheel, and the brake pedal feels distant These compromises don't overshadow the M8's enormous grip, compliant ride, and astonishing nimbleness.
Fuel Economy
EPA estimates sit at 15 mpg city, 22 mpg highway, and 17 mpg combined With the 20.1-gallon fuel tank, expect approximately 342 miles of range between fill-ups Kelley Blue Book estimates monthly fuel costs at approximately $209 based on average driving patterns Premium unleaded fuel is required. If fuel costs concern you, understanding what gas BMWs take helps plan ownership expenses.
