4 Series → F32/F33/F36 → Gran Coupe
How this generation came about, what made it different and how the selected gran coupe fits into the family.
F32/F33/F36 established the 4 Series as the separately named two-door and fastback branch of the contemporary 3 Series family. F32 is the fixed-roof coupe, F33 the convertible with a three-piece retractable hardtop, and F36 the five-door Gran Coupe liftback; their shared badge must not hide the different roof structures, doors and luggage packaging.
BMW presented the F32 coupe in June 2013, followed by the F33 convertible in October 2013 and the F36 Gran Coupe in early 2014. The initial range combined four- and six-cylinder petrol and diesel engines, rear-wheel drive and selected xDrive derivatives, but exact availability and transmission pairings changed by body, market and model year.
A coordinated lifecycle update arrived for the three regular bodies in 2017, bringing revised lighting, chassis tuning, equipment and an already-renamed engine range. F82/F83 M4 models share the broad industrial family but remain separate BMW M generations; they must not be folded into ordinary F32/F33 specifications or production totals.
Dimensions can change with body, market and model year, so this page keeps them tied to the exact factory branch.
| Body | Code | Production | Doors / seats | Length | Luggage |
|---|---|---|---|---|---|
| Coupe | F32 | 2013–2021 | 2-door coupe / 4 | 4,638 mm | 445 L |
| Cabriolet | F33 | 2013–2021 | 2-door convertible / 4 | 4,638 mm | 220–370 L |
| Gran Coupe | F36 | 2013–2021 | 4-door fastback / 5 | 4,640 mm | 480–1,300 L |
The generation could span very different engines and drivetrains. The table keeps output, gearbox, market and production period together.
Documented gran coupe applications; output and availability remain market- and model-year-specific.

Inline and V engines are grouped by engine family, displacement, induction system and emissions specification.
Where diesels were offered, output, injection generation and emissions hardware are recorded market by market.
Mild- and plug-in hybrids are separate derivatives; combustion-engine output must not be substituted for total system output.
Gearboxes, driven wheels and final-drive hardware changed with engine, market and production date.
Gearbox type and unit code follow engine, market and production date. Gear count alone does not identify the transmission.
Catalog architecture: longitudinal layout · rear- or all-wheel drive. All-wheel-drive availability and hardware remain derivative-specific.
Ratio, differential type and electronic control belong to the exact derivative and can differ on performance models.
Suspension, brakes, safety systems and electronics evolved across the range, even when cars shared the same basic architecture.
The important launches, additions and updates did not always happen at the same time for every body or market.
BMW introduced F32 and made the 4 Series a distinct product line above the former 3 Series coupe position.
The second body retained a three-piece retractable hardtop and received body-specific reinforcement and packaging.
The longer-roof five-door liftback added rear doors and a large tailgate without becoming a sedan body.
Coupe, convertible and Gran Coupe were revised together, with dated changes to lighting, suspension and equipment.
The three F-generation bodies did not leave production on one common date as G22, G23 and G26 arrived in sequence.
Performance models, option packages and regional editions may look related, but their engineering and production identity can be very different.
4 Series F32 is a distinct F32/F33/F36 body branch. A lower-roof two-door body with longer doors and a more overtly sporting brief than the corresponding sedan. Engines/drive: N20/B48 petrol I4, N47/B47 diesel I4, N55/B58 petrol I6, N57/B57 diesel I6.
4 Series F33 is a distinct F32/F33/F36 body branch. An open body with a folding roof and generation-specific structural reinforcement, seating and luggage packaging. Engines/drive: N20/B48 petrol I4, N47/B47 diesel I4, N55/B58 petrol I6, N57/B57 diesel I6.
4 Series F36 is a distinct F32/F33/F36 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: N20/B48 petrol I4, N47/B47 diesel I4, N55/B58 petrol I6, N57/B57 diesel I6.
Cabin technology and standard equipment changed by country and year; a build sheet remains the best guide to one individual car.
A practical starting point for inspecting and maintaining a car from this generation — not a diagnosis of an individual example.
| 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. |
The badge and registration year tell only part of the story; production date, body code, engine and factory options complete it.
The story is mapped through English Wikipedia and its bibliography, then important dates and technical claims are checked against BMW material.
