BMW 4 Series

Core summary

BMW 4 Series current generation profile covering the G22, G23 and G26 body styles.

The BMW 4 Series is a compact executive model family built around distinct coupé, convertible and Gran Coupé body styles. The supplied material documents the first generation in detail and identifies current-generation G22, G23 and G26 vehicles through image filenames. The first generation used F32, F33 and F36 designations and was produced from 2013 to 2020. It followed the E92/E93 3 Series coupé and convertible models, while the Gran Coupé added a five-door fastback-style body.

For the current generation, the supplied images include G22 coupé, G23 convertible and G26 Gran Coupé examples, including 2024 G26 files. The reference extract does not specify the current generation's engines, transmissions, dimensions, seating arrangements, trim structure or production dates. Accordingly, this profile separates documented first-generation facts from current-generation identification and avoids treating earlier specifications as current.

History & generations

BMW announced updated 4 Series Coupe and Convertible models in January 2024, followed by the Gran Coupe update in April. These are updates to the G22/G23/G26 family, not the older F32/F33/F36 facelift.

Body, platform & design

The first-generation 4 Series established three related but visually distinct body formats. The F32 coupé was the two-door core model, while the F33 convertible retained a three-part retractable hardtop and added features such as a noise-absorbing headliner and air curtains. The F36 Gran Coupé combined coupé styling with a fastback rear, rear doors and a separate C-pillar behind them.

Relative to the E92 predecessor, the F32 had a 50 mm longer wheelbase, was 31 mm longer overall and 44 mm wider. Its front and rear track widths also increased. The 2017 facelift brought redesigned LED headlights, tail-lights and bumpers, along with new exterior colours and wheel choices. Current-generation image filenames identify G22, G23 and G26 body styles, but the supplied evidence does not support detailed current-generation design measurements or styling claims.

Engine & drivetrain

The documented first-generation range used turbocharged petrol and diesel engines. The extract identifies three-cylinder petrol engines, four-cylinder engines and six-cylinder engines across the F32/F33/F36 family. Launch examples included the petrol 428i and 435i and diesel 420d, with further 420i, 425d, 430d and 435d versions added during 2013. The 418d arrived in 2014, and the 440i and 430i replaced the 435i and 428i in the 2016 model-year changes.

Most first-generation models were available with xDrive. The F82/F83 M4 used the S55 twin-turbocharged straight-six, rated in the extract at 317 kW and 550 N⋅m, with either a six-speed manual or seven-speed dual-clutch transmission. These are first-generation facts and should not be applied to the current G22/G23/G26 range.

Trim differences

The reference extract names four first-generation package groupings: Premium, Luxury Line, Sport and M Sport. It also lists equipment such as a head-up display, an eight-speed automatic transmission and LED headlights. BMW M Performance Parts were offered with items including exhausts, power upgrades, bodywork, a limited-slip differential, steering wheels and interior trim.

The first-generation model-year changes included the 435i ZHP Coupé limited edition in the United States, the 440i replacing the 435i, the 430i replacing the 428i, and the introduction of the 425d. The M4 was treated as a high-performance derivative with F82 coupé and F83 convertible codes. No current-generation trim names, package availability or equipment specifications are provided by the supplied extract or filenames.

Interior & seating

The first-generation extract provides only selected interior and cabin-related information rather than a complete interior specification. The convertible could be equipped with a noise-absorbing headliner, while the range offered an optional head-up display. The 2017 facelift updated the iDrive system to version 6.0 and introduced further interior design changes. M Performance Parts included interior trim and steering-wheel upgrades.

The F36 Gran Coupé retained the same cargo volume as the F30 sedan according to the extract, with 1,300 litres available when its rear seats were folded. It also had 13 mm less rear headroom than the F30 sedan. These measurements apply to the first-generation Gran Coupé only. The supplied current-generation filenames do not confirm cabin design, materials, seating capacity, cargo volume or infotainment details.

Efficiency & range

It does establish that the first-generation range used both petrol and diesel turbocharged engines, with three-cylinder petrol, four-cylinder and six-cylinder engine applications across the family. Engine availability varied by body style and model year.

Because the current-generation G22/G23/G26 powertrain information is not included, no current efficiency comparison can be made from the supplied evidence. The presence of a 2024 filename identifies an image date or model reference, not an efficiency specification. Buyers comparing versions would need market-specific official ratings, which are outside this evidence package.

Safety & equipment

Assistance equipment should be compared using the model-year option list. A 4 Series or M Sport badge does not establish that every available driver-assistance package is installed. An independent safety rating must also match the relevant body and test specification; none is asserted here.

Strengths

The first-generation 4 Series offered unusual breadth within one model family: a dedicated coupé, a retractable-hardtop convertible and a five-door Gran Coupé. The F32 also increased wheelbase, length, width and track dimensions over the E92 predecessor. Turbocharged petrol and diesel engines, xDrive availability and distinct M4 derivatives broadened the range further.

The 2017 facelift brought revised lighting, bumpers, iDrive and suspension changes, while the F36 added a practical fastback body with 1,300 litres of stated cargo capacity when its rear seats were folded. The current-generation image set covers all three principal body-style designations, although the supplied text does not support a technical assessment of that newer generation.

Considerations

The evidence package is uneven between generations. The first-generation F32/F33/F36 is documented with engine families, model-year changes, body-style details and some dimensions, while the current G22/G23/G26 generation is identified mainly through filenames. Earlier engine, transmission, cargo and suspension information must not be assumed to describe current cars.

The 4 Series family also includes substantially different body formats and performance derivatives. A coupé, convertible, Gran Coupé and M4 should not be treated as interchangeable. Availability of xDrive, packages, equipment and engines varied by model and market in the first generation, and current-generation availability is not documented here.

Recommended use

Choose the body before the trim: Coupe prioritizes a two-door format, Convertible adds open-roof motoring, and Gran Coupe adds rear-door access. Those differences are more useful for an initial shortlist than treating the whole range as one body style.

FAQ

Q: Is this the F-generation range? A: No; it covers G22 Coupe, G23 Convertible and G26 Gran Coupe.

Q: Is the M4 specification interchangeable? A: No; it is a separate performance model.
