Trunk dimensions BMW i4

The BMW i4 2022 offers a trunk with a volume of about 16.6 cu ft, increasing to approximately 45.6 cu ft when the rear seats are folded down.

The rear bench is split 40:20:40, allowing flexibility when transporting luggage. The interior is modernly designed, with high-quality materials and a clear arrangement of controls.

The trunk dimensions vary within the model range, with the trunk shape typically flat and spacious, facilitating loading. The loading edge is relatively low, simplifying access. Overall, the i4 offers good practicality typical for an electric sports car, combining functionality with appealing design.

Model Information

The BMW i4 is a fully electric hatchback model that is part of the BMW 4 Series. It combines sporty design with innovative electric mobility. The i4 offers an impressive range, advanced technology, and a comfortable interior.

With a focus on performance and efficiency, the i4 is an attractive option for environmentally conscious drivers who do not want to compromise on driving pleasure.

Variants of the Same Series

Within the BMW 4 Series, there are various variants including the coupe, convertible, and the i4 as a hatchback. It is important not to confuse these models as they have different body styles and characteristics.

While the coupe is sportier and the convertible more open, the i4 as a hatchback offers a combination of everyday usability and sporty flair.

Yearly Differences

The BMW i4 was introduced in 2021, and since then there have been no significant changes to the body or trunk dimensions. Future model years may see adjustments affecting the dimensions. However, current information on possible changes is not available.

Direct Competitors

Direct competitors of the BMW i4 include models such as the Tesla Model 3 and the Audi Q4 e-tron.

The Tesla Model 3 offers a trunk volume of about 15 cu ft, which is slightly less than the i4. The Audi Q4 e-tron, on the other hand, has a volume of around 18.4 cu ft, making it superior in this regard. These differences can be decisive for buyers who value cargo space.

More Affordable Alternatives

More affordable alternatives with similar trunk dimensions include the Hyundai Ioniq 5 and the Kia EV6. The Hyundai Ioniq 5 offers a trunk volume of about 18.6 cu ft, while the Kia EV6 has similar dimensions.

Both models are generally less expensive than the BMW i4 and still offer an appealing combination of space and features.

Trunk Volume

The BMW i4 Sedan 2025 offers different figures depending on the measurement method. Manufacturer specification: 16.6 cu ft, independent measurements: approx. 13.1 cu ft (up to the luggage compartment cover).

When the cover is removed, it is about 450–16.6 cu ft up to the rear window. Folding down the rear seat results in approx.

26.5 cu ft up to the window sill (independent) and up to 41 cu ft–45.6 cu ft roof-high (varied figures between measurement and manufacturer).

Under the trunk floor, there is an additional approx. 0.5 cu ft storage space for small items (e.g., charging cables). Practically, about seven standard beverage crates fit into the cargo area.

Everyday conclusion: Realistically, expect around 370–15.9 cu ft usable volume in normal operation. This is sufficient for shopping, suitcases for short trips, and daily use; those regularly needing large bulky volume benefit from folded seats (up to ~26.5 cu ft up to the window sill).

Vehicle Size and Parking Friendliness

Dimensions: 4.78 m length, 1.85 m width, 1.45 m height. Compared to an average car, the i4 is about 8.7 in longer and about 4.7 in lower. Compared to a standard parking space, the vehicle is and about 25.6 in narrower, so it usually fits into regular parking spots.

Everyday effect: The longer body requires a bit more caution when parking and maneuvering (underground garages, tight parking garages). The width is average, so parking spaces are generally sufficient. The lower height is an advantage for underground garages and drive-throughs.

Trunk Usability and Flexibility

- The tailgate is electric and in many trims can be combined with hands-free opening by foot sweep; the opening height is adjustable (practical for low garages).
- The loading edge is just under 28 in, which facilitates loading and unloading.

Inside, however, there is a step of about 4.3 in between the loading edge and floor, which makes sliding long, flat objects difficult.
- The rear seat backrest is split into three foldable sections and can be easily unlocked; folding down the backrests creates a largely flat loading floor.

Bag hooks, nets, and a small compartment under the floor are standard equipment. There is no frunk (storage compartment under the front hood).

Everyday effect: The i4 combines good everyday usability with aspects to be aware of: ergonomically usable loading edge and electric tailgate facilitate handling, the step in the cargo area and the sloping rear window limit the accommodation of very flat or very tall items.

For families and vacations with luggage, the flexibility provided by the three-part rear seat is useful.

General Model Information

Familiarity & Special Features: The BMW i4 is a fully electric sedan in the D-segment. Characteristic are the underfloor battery (which according to the fact sheet does not limit storage space), the sporty space concept, and the standard electric tailgate.

Another feature: good trunk lighting (two LEDs) and practical detail equipment (nets, storage compartment, bag hooks).

Particularities: The sloping rear limits the vertical usability of the trunk compared to a wagon. With certain key options (keyless), there are indications of security risks due to radio extension — this is a vulnerability to consider if you use keyless.

Price-Performance and Competition Assessment: Specific prices are not listed in the fact sheet.

Competitors in the segment include Tesla Model 3 and Polestar 2 (similar range/performance with sedan layout); depending on equipment, the i4 also competes with models from Mercedes‑EQ and Audi in the electric mid-size segment.

Decisive for price-performance ratio are equipment level, battery capacity, and optional comfort packages (e.g., keyless system, M Sport package).

In summary: The i4 offers practical trunk sizes for everyday use (realistically 370–15.9 cu ft), good flexibility through the three-part rear seat and electric tailgate.

Limitations are the sloping rear section and the interior step in the cargo area; with folded seats, the vehicle is also suitable for larger loads (up to ~26.5 cu ft/41 cu ft depending on measurement).
