The 2024 BMW M8 Gran Coupe delivers 617 horsepower from its twin-turbo V8, accelerates to 60 mph in just 2.7 seconds, and offers four-door practicality wrapped in striking fastback styling[1]. Starting at $138,800, buyers are paying an average of $137,189 after negotiation, making this flagship more accessible than its sticker suggests[2]. For 2024, the M8 Gran Coupe carries forward unchanged from previous years, continuing as a compelling alternative to the Mercedes-AMG GT 63.
The BMW M8 Gran Coupe occupies a unique space in the high-performance four-door segment. Despite its coupe designation, this is a proper sedan with a dramatically swept roofline that sacrifices some rear headroom for visual impact[1]. The result turns more heads than conventional sedan silhouettes while maintaining genuine everyday usability.
Unchanged since its 2020 debut, the M8 Gran Coupe has aged gracefully while avoiding the controversial design choices BMW has adopted on newer models[3]. Edmunds testing confirms the car remains competitive, recording 2.7-second 0-60 mph times and 21.8 mpg on their mixed driving loop[4]. For buyers exploring the BMW lineup, this represents the pinnacle of non-hybrid performance sedans.

The M8 Gran Coupe presents one of BMW's most cohesive designs, with a sweeping fastback roofline flowing into a short rear deck[4]. Quad exhaust tips, aggressive front air intakes, and available carbon fiber exterior elements distinguish the M8 from the standard 8 Series Gran Coupe[4]. The M Carbon Fiber Exterior Package adds approximately $5,400 but significantly enhances the aggressive appearance[6].
At 201 inches long and 77 inches wide, the M8 Gran Coupe commands presence without appearing overwrought[5]. The design has aged well since its 2020 introduction, predating BMW's larger kidney grille designs.
Inside, the M8 Gran Coupe delivers what Edmunds calls impeccable materials and build quality[4]. The cabin feels comfortable and quiet, isolating occupants from road noise while allowing the V8's character to emerge on demand[4].
Standard equipment includes:
Car and Driver notes the main drawback: the squashed roofline compromises rear headroom[1]. Taller passengers will find the back seats cramped. Edmunds adds that the button-heavy interior appears cluttered compared to cleaner designs from competitors[4]. However, many reviewers consider this older iDrive interface more intuitive than BMW's latest systems.
The trunk offers approximately 15 cubic feet of cargo space, competitive for this class and notably more practical than the two-door M8 Coupe[5].
The 2024 M8 Gran Coupe's twin-turbocharged 4.4-liter V8 produces 617 horsepower and 553 lb-ft of torque[1]. An eight-speed automatic transmission routes power to all four wheels through BMW's xDrive system. Crucially, a selectable rear-wheel-drive mode enables tail-out antics when desired[1].
Car and Driver recorded a 2.7-second 0-60 mph time and a 10.8-second quarter-mile at 129 mph[1]. These numbers impress for any performance car, let alone one weighing over 4,300 pounds with four doors. The M8 Gran Coupe also delivers more than 1.0 g of cornering grip[1].
The M8 Gran Coupe delivers rapid, effortless acceleration at all speeds[4]. Edmunds praises the excellent blend of power, size, and handling[4]. The steering provides better feedback than the competing Mercedes-AMG GT 63, creating a more connected driving experience[3].
However, Car and Driver identifies inconsistent brake-pedal feel and a sometimes-too-sporty ride as compromises[1]. Edmunds concurs, noting the car lacks the raw performance thrills of some rivals[4]. That said, the overall verdict remains positive: the M8 Gran Coupe is furiously quick and incredibly grippy[1].
Understanding what fuel BMWs require is essential. The M8 demands premium unleaded, and the gas guzzler tax adds $1,000 to the purchase price[6].
EPA estimates sit at 15 mpg city, 22 mpg highway, and 17 mpg combined[5]. However, real-world testing reveals better numbers are achievable. Edmunds recorded an exceptional 21.8 mpg on their 115-mile mixed driving loop[4]. Car and Driver observed 16 mpg during their testing[1].
Owner forums report typical averages of 14-16 mpg with spirited driving and 22+ mpg on highway journeys[7]. With the 20.1-gallon fuel tank, expect approximately 340-440 miles between fill-ups depending on driving style.
The 2024 M8 Gran Coupe Competition comes well-equipped. Standard features include:

BMW covers complimentary maintenance for 3 years or 36,000 miles, with a limited warranty spanning 4 years or 50,000 miles[1]. For context on BMW maintenance costs, expect premium pricing once warranty coverage expires.
Ownership considerations include:
The M8 Gran Coupe draws on BMW's established S63 V8 engine, which has proven generally reliable when properly maintained[9]. Common reported issues include:
The 2024 model year has benefited from fixes implemented in earlier years. Owners who maintain vehicles according to BMW's schedule report positive experiences[8].
| Vehicle | Starting MSRP | Power | 0-60 mph |
|---|---|---|---|
| 2024 BMW M8 Gran Coupe | $138,800[4] | 617 hp[1] | 2.7 sec[1] |
| 2024 Mercedes-AMG GT 63 | ~$184,900[3] | 577 hp[10] | 3.1 sec[3] |
| 2024 Audi RS7 | ~$128,600 | 621 hp | ~3.4 sec |
| 2024 Porsche Panamera Turbo | ~$178,000 | 621 hp | ~3.0 sec |
The M8 Gran Coupe offers more power and quicker acceleration than the Mercedes-AMG GT 63 while costing approximately $46,000 less[3][10]. However, the AMG GT 63 provides slightly more torque (590 lb-ft vs 553 lb-ft) and marginally better skidpad performance (1.08 g vs 1.02 g)[3][10]. Edmunds testing found the M8's steering offers better feedback and a more connected feel than the Mercedes[3].
For buyers comparing within BMW, the M8 Coupe offers the same powertrain in a two-door package, while the [M5] provides a more traditional sedan shape.
