The 2025 BMW M8 Gran Coupe delivers 617 horsepower from its twin-turbo V8, accelerates to 60 mph in just 2.7 seconds in testing, and offers four-door practicality wrapped in one of BMW's most striking designs[1]. Starting at $142,175, this four-door flagship combines the raw performance of the two-door M8 with usable rear seats and a larger trunk[2]. With the new M5 gaining significant weight from its hybrid system, the M8 Gran Coupe now offers a compelling alternative with a better power-to-weight ratio[1].
The BMW M8 Gran Coupe occupies a unique space in the performance sedan market. Despite its name suggesting a coupe, this is a proper four-door sedan with a sweeping fastback roofline that sacrifices some rear headroom for dramatic styling[3]. The result is a vehicle that turns heads more effectively than the traditional sedan silhouette of competitors.
Road and Track testing revealed an interesting dynamic: while the new G90 M5 produces more total power with its hybrid system, each horsepower in the M8 Gran Coupe moves just 7.9 pounds of car compared to 7.3 pounds in the heavier M5[1]. This weight advantage translates to the M8 Gran Coupe being three-tenths quicker to 60 mph than BMW's latest super sedan[1]. For buyers who prioritize a traditional powertrain without hybrid complexity, the M8 Gran Coupe offers significant appeal. If you are comparing within the BMW lineup, this represents the pinnacle of non-hybrid performance.

The M8 Gran Coupe presents one of BMW's most cohesive designs. The extended roofline flows seamlessly into the rear decklid, creating a silhouette that Road and Track describes as making most sedans look ugly by comparison[1]. Quad exhaust tips, aggressive front air intakes, and available carbon fiber exterior elements distinguish the M8 from the standard 8 Series Gran Coupe[3].
The design has aged gracefully since its 2020 introduction, avoiding the controversial styling choices that have divided opinion on newer BMW models. At 201 inches long, the M8 Gran Coupe commands attention without appearing overwrought[4].
Inside, the M8 Gran Coupe delivers impeccable materials and build quality that Edmunds rates among the best in the segment[2]. The cabin feels comfortable and quiet, isolating occupants from road noise while still allowing the V8's character to come through when desired[2].
Standard equipment includes:
Car and Driver notes one significant drawback: the squashed roofline compromises rear-seat headroom[3]. Taller passengers will find the back seats cramped despite adequate legroom. Edmunds echoes this concern, pointing out the button-heavy interior can appear cluttered compared to cleaner designs from competitors[2]. However, Road and Track praises the older interface as user-friendly compared to BMW's latest systems[1].
The trunk offers approximately 15 cubic feet of cargo space, which is competitive for this class and significantly more practical than the two-door M8 Coupe[4].
The heart of the M8 Gran Coupe is BMW's S63 twin-turbocharged 4.4-liter V8, producing 617 horsepower and 553 lb-ft of torque[2]. An eight-speed automatic transmission routes power to all four wheels through BMW's xDrive system, with a crucial feature: drivers can disengage the front axle, transforming the M8 into a rear-wheel-drive machine for spirited driving or controlled drifts[3].
Road and Track recorded a 2.7-second 0-60 mph time, making the M8 Gran Coupe three-tenths quicker than the new hybrid M5[1]. The powerplant delivers its thrust with what Road and Track describes as muscular, charismatic V8 character and huge performance[1].
The M8 Gran Coupe rewards a confident hand at the wheel. Road and Track notes the ride and handling improve with strong inputs rather than delicate ones[1]. Push hard, and grip is plentiful, with enough feedback when hustling to involve the driver in a way most new cars do not[1].
Car and Driver identifies absent steering feedback and irregular brake pedal feel as compromises[3]. Despite these criticisms, the overall verdict remains positive: the M8 Gran Coupe is fiercely fast, incredibly grippy, and ridiculously fun[3].
MotorTrend observes that in Competition guise set to RWD mode, the M8 can easily drift, demonstrating a quickness and agility that belies its considerable size and weight[6]. The AWD configuration provides more stability and neutrality, suitable for daily driving[6]. Understanding what fuel BMWs require is essential, as the M8 demands premium unleaded.
EPA estimates sit at 15 mpg city, 22 mpg highway, and 17 mpg combined[4]. However, real-world testing reveals better numbers are achievable with restraint. Edmunds recorded 21.8 mpg on their 115-mile mixed test route[2]. Independent testing by The Smoking Tire achieved 27 mpg on a highway-focused route at 70 mph[7].
Owner forums report typical averages of 14-16 mpg with spirited driving and 22+ mpg on highway journeys[8]. With the 20.1-gallon fuel tank, expect approximately 340-440 miles between fill-ups depending on driving style[4].
The 2025 M8 Gran Coupe Competition comes well-equipped. Standard features include:
Available upgrades include:
Driver-assistance technology includes forward-collision warning with automated emergency braking, side-mounted airbags, and curtain airbags for both rows[4]. Adaptive cruise control, blind-spot monitoring, and night vision are optional[4].
| Body Style | Starting MSRP |
|---|---|
| M8 Gran Coupe Competition | $142,175[3] |
| M8 Competition Coupe | $140,975[3] |
| M8 Competition Convertible | $150,000[3] |
Prices as of December 2025. Destination fee: $1,175. Gas guzzler tax: $1,000.
Edmunds reports buyers are paying approximately $5,800 below MSRP on average, with transactions starting around $136,400 before options[2]. However, inventory is extremely limited, with fewer than 100 units available nationwide[2]. High demand means vehicles average just 13 days on dealer lots[2].
Edmunds projects total 5-year ownership costs of approximately $161,762[9]:
| Category | 5-Year Cost |
|---|---|
| Fuel | $17,981[9] |
| Depreciation | ~$77,943[10] |
| Insurance | ~$22,000-25,000 |
| Maintenance | ~$5,500-6,000 |
BMW covers complimentary maintenance for 3 years or 36,000 miles, with a limited warranty spanning 4 years or 50,000 miles[3]. For context on BMW maintenance costs, expect premium pricing once warranty coverage expires.
The M8 Gran Coupe draws on BMW's established S63 V8 engine, which has proven generally reliable when properly maintained[11]. Common reported issues include:
Owners who maintain their vehicles according to BMW's schedule report positive experiences. The consensus from forums emphasizes using quality synthetic oil, being gentle on cold starts, and rotating tires every 5,000-7,000 miles[13].
Pros:
Cons:
| Vehicle | Starting MSRP | Power | 0-60 mph |
|---|---|---|---|
| 2025 BMW M8 Gran Coupe | $142,175[3] | 617 hp[2] | 2.7 sec[1] |
| 2025 Mercedes-AMG GT 63 | ~$185,000[14] | 577-831 hp[14] | 2.7-3.3 sec |
| 2025 Audi RS7 | ~$128,600[4] | 621 hp | ~3.4 sec |
| 2025 Porsche Panamera Turbo | ~$178,000 | 621 hp | ~3.0 sec |
The M8 Gran Coupe offers more style than the RS7, more power than base AMG GT 63 variants, and better value than the Porsche Panamera Turbo. For buyers prioritizing design and a traditional V8 character without hybrid intervention, the M8 Gran Coupe delivers a compelling package.
