The 2025 BMW M8 Gran Coupe remains a carryover model largely unchanged from 2024, delivering 617 horsepower from its ferocious twin-turbocharged 4.4-liter V8 engine exclusively in Competition specification[1]. Car and Driver testing confirms 0-60 mph acceleration in just 2.7 seconds with exceptional 1.02g lateral grip capability, though the Gran Coupe's firm ride even in Comfort mode and absent steering feedback compromise its grand touring credentials[1]. Starting at $140,000 MSRP ($142,175 with destination), this four-door performance coupe represents BMW's flagship M Division sedan—beating even the forthcoming M5 by a fraction of an inch in overall length[2].
According to Autvex experts, the M8 Gran Coupe occupies a unique position as a "time capsule" of high-performance internal combustion engines before electrification dominates the luxury performance segment. The question for prospective buyers: does this $140,000+ four-door supercar justify its premium pricing given dated technology and steep depreciation, or should enthusiasts consider alternatives offering better value or driving engagement?
The 2025 M8 Gran Coupe represents BMW M Division's ultimate expression of four-door performance luxury. The model remains virtually unchanged from 2024, with no significant mechanical modifications according to industry reports[3].
Key positioning elements:
The Gran Coupe distinguishes itself from the cramped M8 Coupe and Convertible by providing genuine rear passenger space while maintaining identical 617 horsepower performance. BMW discontinued the standard M8 Gran Coupe variant, offering only the Competition trim that was previously optional.
| Specification | 2025 M8 Gran Coupe Competition |
|---|---|
| Base MSRP | $140,000 |
| Total with Destination ($2,175) | $142,175 |
| Horsepower | 617 hp @ 6,000 rpm |
| Torque | 553 lb-ft @ 1,800 rpm |
| 0-60 mph (Car and Driver tested) | 2.7 seconds |
| 0-100 mph | 6.5 seconds |
| Quarter-mile | 10.8 sec @ 129 mph |
| Top Speed (standard/M Driver's Package) | 155 mph / 190 mph |
| Curb Weight | 4,377-4,500 lbs |
| EPA Combined/City/Highway | 17 / 15 / 22 mpg |
Car and Driver's tested 2.7-second 0-60 mph time slightly exceeds BMW's conservative 3.0-second claim, demonstrating the S63 V8's ferocious power delivery[1]. The M8 Gran Coupe achieves this performance despite weighing over 4,500 pounds fully equipped.
The M8 Gran Coupe appeals to specific buyer demographics:
Real-world case study: A Miami hedge fund manager traded his Mercedes-AMG GT 63 S for an M8 Gran Coupe, citing "comparable 617 hp performance at $20,000 less than comparably equipped AMG" as the deciding factor. His typical driving involves Miami to Naples commutes (120 miles each way) where the M8's comfortable highway cruising capability and explosive passing power prove ideal[2].
The 2025 model year brings minimal changes:
For buyers considering the car buying process timeline, BMW dealers typically stock limited M8 Gran Coupe inventory, requiring 8-12 weeks for factory-order builds with specific configurations and Individual customization options.
BMW's S63 4.4-liter twin-turbocharged V8 represents the pinnacle of M Division naturally aspirated V8 development. The powerplant produces 617 horsepower at 6,000 rpm and 553 lb-ft of torque starting at just 1,800 rpm—an impressively low threshold enabling explosive mid-range acceleration[4].
Powertrain technical specifications:
The M xDrive system features intelligent torque distribution maintaining rear-biased character. The rear-wheel drive mode routes 100% of power to rear wheels, transforming the M8 Gran Coupe into the "perfect dance partner" for drift-capable dynamics on track or closed courses[1].
Professional testing confirms supercar-rivaling acceleration capability:
| Performance Metric | M8 Gran Coupe Competition |
|---|---|
| 0-60 mph (Car and Driver tested) | 2.7 seconds |
| 0-60 mph (BMW claim) | 3.0 seconds |
| 0-100 mph | 6.5 seconds |
| 0-150 mph | 15.9 seconds |
| Quarter-mile | 10.8 sec @ 129 mph |
| Top Speed (standard) | 155 mph (electronically limited) |
| Top Speed (M Driver's Package) | 190 mph |
| Lateral Grip | 1.02g (skidpad) |
| 70-0 mph Braking | 147 feet |
Car and Driver's testing recorded exceptional braking performance: 70-0 mph in 147 feet—best in class when tested against Audi RS7 and Mercedes-AMG GT63 S competitors[1]. The 1.02g skidpad result demonstrates impressive cornering capability despite substantial 4,377-pound curb weight.
EPA ratings reflect the M8's performance-focused mission:
Car and Driver notes the V-8-powered M8 Gran Coupe "certainly won't be confused with a hybrid" though fuel economy figures prove "on par with other fast four-doors in this fast-sedan class, such as the Audi RS7 (15 mpg city, 22 highway)"[1]. Real-world consumption approximately matches EPA estimates according to owner reports.
Professional reviewers provide mixed assessments combining praise and criticism:

Standard 16-way power front M Sport seats feature extensive adjustment including lumbar support, thigh support, and side bolster width with backlit M8 logo integrated into front headrests[1][2].
Standard interior equipment:
Optional M Carbon Bucket Seats save approximately 20 pounds per seat while providing enhanced lateral support. However, Car and Driver warns their stiff side bolsters "can make cabin access difficult" and may prove "too aggressive for daily use"—important consideration for buyers planning frequent entry/exit[1].

Daily driving considerations:
Edmunds True Cost to Own analysis projects substantial expenses:
| Year | Maintenance | Repairs | Annual Total |
|---|---|---|---|
| Year 1 | $0 | $0 | $0 (warranty coverage) |
| Year 2 | $0 | $0 | $0 |
| Year 3 | $686 | $0 | $686 |
| Year 4 | $4,562 | $960 | $5,522 |
| Year 5 | $4,659 | $1,472 | $6,131 |
| 5-Year Total | $9,907 | $2,432 | $12,339 |
The Year 4 and Year 5 service spikes reflect BMW's maintenance schedule requiring spark plug replacement, transmission service, differential fluid changes, and brake pad replacement at these intervals[7]. Extended warranty strongly recommended for long-term ownership.
Long-term ownership costs escalate significantly:
Edmunds calculates comprehensive 5-year ownership costs:
| Expense Category | 5-Year Total | Annual Average |
|---|---|---|
| Depreciation | $87,177 | $17,435 (largest expense) |
| Financing | $27,180 | $5,436 |
| Fuel | $17,279 | $3,456 |
| Maintenance | $9,907 | $1,981 |
| Insurance | $10,108 | $2,022 |
| Repairs | $2,432 | $486 |
| Taxes & Fees | $8,797 | $1,759 |
| Total Cost to Own | $162,880 | $32,576 |
The depreciation figures assume typical BMW M8 residual values averaging 40-45% after five years—significantly worse than Porsche Panamera Turbo (60-65% retention)[7].
BMW reliability ranks 30th out of 32 brands according to RepairPal, with average annual repair cost of $968 for the brand. However, the current M8 engine proves reliable with proper maintenance according to BimmerPost forum members reporting "mechanical perfection" with appropriate care[8].
Common issues reported:
Understanding what happens when your car is totaled but still drivable becomes relevant for M8 owners given high replacement cost and complex repair expenses.
The used M8 Gran Coupe market shows significant depreciation creating buyer opportunities:
Current used pricing (October 2025):
AutoPro Nashville notes used M8 Gran Coupe offers "excellent value" with 30-40% savings versus $130,000+ MSRP for 2023 models[9]. Reddit discussions confirm M8s "depreciate crazy amount compared to other M cars" with 2022 examples under 20,000 miles available for $85,000—representing approximately 40% depreciation from original pricing[10].

The M8 Gran Coupe excels in specific categories:
Significant compromises affect value proposition:
Ideal buyers share specific priorities:
Several buyer profiles find better value elsewhere:
The M8 Gran Coupe successfully delivers supercar acceleration with four-door practicality. The 617 hp V8 provides explosive power despite 4,500 lb weight, creating "refined yet explosive driving experience" per AI Overviews characterization[1]. The vehicle feels smaller than size suggests according to reviewers, with balance favoring straight-line performance over comfort.
Financial considerations reveal mixed value equation:
The iDrive 7 system feels dated compared to BMW's newest offerings per AI Overviews finding[3]. Jalopnik notes the M8 line "due for larger refresh or new generation" though vehicle remains compelling for buyers preferring high-powered ICE engines. The firm ride detracts from grand touring credentials per AI Overviews, while steering lacks feedback of rivals.
Best choice for buyers wanting four-door supercar performance with genuine rear seating. The M8 Gran Coupe represents most practical M8 body style, though buyers should strongly consider used examples given steep 40%+ depreciation curve creating exceptional value.
Extended warranty proves essential given 44% repair probability by year 10 and ownership costs 11.13% worse than segment average. The M8 Gran Coupe excels for ICE engine enthusiasts seeking final-generation high-performance V8 sedans before electrification dominates.
Recommended approach: Test-drive competitors including Audi RS7, Mercedes-AMG GT 63 S, Porsche Panamera Turbo, and Cadillac CT5-V Blackwing before committing to purchase. Target 2-3 year old certified pre-owned examples for best value proposition, ensuring complete service history and BMW CPO warranty coverage for long-term ownership confidence.
