M4 F82/F83: history, design and engineering
How this generation came about, what made it different and how the selected cabriolet fits into the family.
F82/F83 created the M4 name for the coupé and convertible successors to the E9x M3 two-door cars. Both use the S55 twin-turbo inline-six and share the F80 engineering family, but the F83 retractable hardtop has different structure, roof mechanism, luggage capacity and mass.
The range grew from standard cars to Competition and highly distinct limited derivatives: GTS with water injection, DTM Champion Edition, CS and edition packages. GTS and CS require their own output, aerodynamics, suspension and production records; cosmetic editions should inherit the correct underlying mechanical row.
Manual and M DCT availability, rated output and equipment vary by market. The M4 GT4 and GT3 are racing cars, while the M4 GTS road car is a homologated production derivative; the catalog must make that boundary visible.

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 cabriolet applications; output and availability remain market- and model-year-specific.
| Model | Years | Engine | Output | Transmission | Drive | Market | Source |
|---|---|---|---|---|---|---|---|
| M4 Coupé / Cabriolet | 2014–2020 | S55B30T0 twin-turbo inline-six | 431 PS / 425 hp US | 6MT / 7DCT | RWD | Global range | BMW M3 F80 and BMW M4 F82 |
| M4 Competition | 2016–2020 | S55B30T0 twin-turbo inline-six | 450 PS / 444 hp US | 6MT / 7DCT | RWD | Global range | BMW M3 F80 and BMW M4 F82 |
Factory designations

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
- F82: 4,671 mm × 1,870 mm × 1,383 mm
- F83: 4,671 mm × 1,870 mm × 1,386 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.
First M4
F82 Coupé and F83 Convertible launched the renamed two-door M family.
Competition and GTS
The regular performance package and water-injected limited coupé expanded the range.
Lifecycle update and CS
Lighting and equipment changes arrived alongside the focused CS derivative.
First M4 generation ends
F82/F83 production concluded before the G82/G83 successor.
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.
Coupe
F82M4 F82 is a distinct F82/F83 body branch. A lower-roof two-door body with longer doors and a more overtly sporting brief than the corresponding sedan. Engines/drive: S55B30T0.
Cabriolet
F83M4 F83 is a distinct F82/F83 body branch. An open body with a folding roof and generation-specific structural reinforcement, seating and luggage packaging. Engines/drive: S55B30T0.
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
- F82 — Coupe; F83 — Cabriolet
- Range designations
- M4, M4 Competition, M4 CS, M4 GTS
- Powertrain families
- S55B30T0
- 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.
Where the information comes from
The story is mapped through English Wikipedia and its bibliography, then important dates and technical claims are checked against BMW material.

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.
- F82 Coupé and F83 Convertible must have separate mass, dimensions and body records.
- Road GTS/CS and competition-only GT4/GT3 cars belong to different catalog layers.
- 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.
