M8 F91/F92/F93: history, design and engineering
How this generation came about, what made it different and how the selected gran coupe fits into the family.
F91/F92/F93 brought the M8 name to series production after the E31 prototype had remained experimental. Convertible, Coupé and Gran Coupé use the S63 twin-turbo V8, eight-speed M Steptronic and configurable M xDrive, but their roof, wheelbase, seating, luggage and mass require distinct body specifications.
Launch ranges included regular and Competition models in some markets; later programmes concentrated on Competition. Rated output and standard equipment therefore depend on market and date, while the M8 Competition's 2WD mode remains part of its M xDrive system.
The M8 Gran Coupé is not an M6 or M5 derivative despite shared components. M8 GTE was a purpose-built racing programme that preceded the road launch and must not supply road-car dimensions or engine output.

Engines and powertrains
The generation could span very different engines and drivetrains. The table keeps output, gearbox, market and production period together.
Factory modification matrix
Documented gran coupe applications; output and availability remain market- and model-year-specific.
| Model | Years | Engine | Output | Transmission | Drive | Market | Source |
|---|---|---|---|---|---|---|---|
| M8 | 2019–2022 | S63B44T4 twin-turbo V8 | 600 PS / 591 hp US | 8AT | M xDrive | Global range | BMW M8 Coupé and BMW M8 Competition Coupé |
| M8 Competition | 2019–present | S63B44T4 twin-turbo V8 | 625 PS / 617 hp US | 8AT | M xDrive | Global range | BMW M8 Coupé and BMW M8 Competition Coupé |

High-performance powertrain
Engine, cooling, exhaust, software and transmission form a distinct M or ALPINA specification rather than an option package on the base model.
Diesel derivatives
Where diesels were offered, output, injection generation and emissions hardware are recorded market by market.
Electrification
Mild- and plug-in hybrids are separate derivatives; combustion-engine output must not be substituted for total system output.
How power reaches the road
Gearboxes, driven wheels and final-drive hardware changed with engine, market and production date.
Transmissions
Gearbox type and unit code follow engine, market and production date. Gear count alone does not identify the transmission.
Driven wheels
Catalog architecture: BMW M · longitudinal layout · rear-wheel drive. All-wheel-drive availability and hardware remain derivative-specific.
Final drive
Ratio, differential type and electronic control belong to the exact derivative and can differ on performance models.
What changed underneath
Suspension, brakes, safety systems and electronics evolved across the range, even when cars shared the same basic architecture.
Body-branch dimensions
- F91: 4,867 mm × 1,907 mm × 1,353 mm
- F92: 4,867 mm × 1,907 mm × 1,362 mm
- F93: 5,098 mm × 1,943 mm × 1,420 mm
Body & suspension
- Mounting points and geometry follow the body branch
- Springs and dampers follow axle load and chassis package
- Wheels and permitted loads follow the factory label
Brakes & steering
- Brake size follows engine and equipment
- Assistance type and steering ratio can change
- ABS/DSC generation follows model year
Passive safety
- Airbag count varies by market and year
- SRS parts are VIN-specific
- Structural repairs require factory procedures
Electronics
- Vehicle-bus generations changed during production
- Control-unit software levels must remain compatible
- Retrofits are recorded separately from factory equipment
How the generation evolved
The important launches, additions and updates did not always happen at the same time for every body or market.
M8 competition programme
M8 GTE raced before the series road car but remained a separate competition design.
Coupé and Convertible
F92 and F91 launched the first production M8 family.
Gran Coupé
F93 added the long-wheelbase four-door body.
Lifecycle update
Design, displays and equipment changed as the range centred on Competition.
The versions that stood apart
Performance models, option packages and regional editions may look related, but their engineering and production identity can be very different.
Cabriolet
F91M8 F91 is a distinct F91/F92/F93 body branch. An open body with a folding roof and generation-specific structural reinforcement, seating and luggage packaging. Engines/drive: S63B44T4 V8.
Coupe
F92M8 F92 is a distinct F91/F92/F93 body branch. A lower-roof two-door body with longer doors and a more overtly sporting brief than the corresponding sedan. Engines/drive: S63B44T4 V8.
Gran Coupe
F93M8 F93 is a distinct F91/F92/F93 body branch. A four-door fastback combining a coupe-like roofline with easier rear access and a large tailgate or sedan-style luggage opening. Engines/drive: S63B44T4 V8.
Inside the car
Cabin technology and standard equipment changed by country and year; a build sheet remains the best guide to one individual car.
Cabin & comfort
- Trim and seats follow option codes
- Climate systems vary by market
- Audio and navigation changed by model year
Lighting & assistance
- Lamp technology and modules follow production date
- Driver assistance cannot be inferred from buttons alone
- Regional rules affect lighting and warnings
What to check today
A practical starting point for inspecting and maintaining a car from this generation — not a diagnosis of an individual example.
Identify first
- Match VIN on body and documents
- Obtain the factory option list
- Confirm market and production date
Inspect the structure
- Check repairs and corrosion
- Assess suspension, brakes and tyres
- Compare fitted parts with factory specification
Mechanical history
- Read faults with compatible diagnostics
- Verify engine and transmission maintenance
- Separate invoices from unsupported verbal history
| Item | Interval / trigger | Catalog note |
|---|---|---|
| Engine oil & filter | CBS/factory schedule; time and mileage for historic cars | Oil approval follows the exact engine and market. |
| Brake fluid | Time-based factory schedule | ABS/DSC-compatible bleeding procedure is required after hydraulic work. |
| Coolant | Factory schedule and condition | Fluid specification and bleeding method are generation-specific. |
| Transmission & final drives | Unit type and operating conditions | Use the exact approved fluid; no one interval fits every derivative. |
How to identify the exact car
The badge and registration year tell only part of the story; production date, body code, engine and factory options complete it.
- Factory body codes
- F91 — Cabriolet; F92 — Coupe; F93 — Gran Coupe
- Range designations
- M8, M8 Competition, M8 Gran Coupe, M8 Cabriolet
- Powertrain families
- S63B44T4 V8
- VIN
- Identifies model, plant and production branch and keys the parts catalog and factory equipment record.
- Production date
- More useful than first-registration year when choosing parts and locating technical revisions.
- Type code
- Refines engine, body, market and transmission combination.
- Option codes
- Confirm factory equipment; later retrofits are recorded separately.
- Unit number
- Supports engine or gearbox originality checks and component applicability.

Notes and limitations
- Research revision dated 2026-08-10: English Wikipedia was used as a subject and bibliography map; key claims were checked against the listed primary BMW Group material.
- F91, F92 and F93 require independent body records; Competition availability is market/date scoped.
- M8 GTE and the E31 M8 prototype are historical links, not F9x production modifications.
- Tree years describe the worldwide generation lifecycle; individual market dates may be narrower.
- Exact dimensions, power, weight and emissions belong at body, engine, market and model-year level.
- Known-issue guidance is editorial context and never replaces inspection of the individual vehicle.
