Used BMW i4 Rear Cross Member

The BMW i4 launched in 2021 on the G26 platform and received a facelift in 2024, bringing styling and equipment updates. The rear cross member is a structural body component, so the key question is whether pressing or mounting-point changes were introduced at the 2024 facelift boundary — this is something you should confirm with the breaker against your exact registration before ordering. Parts from within the same pre-facelift (2021–2023) or post-facelift (2024 on) period are the most straightforward like-for-like swap, but never assume fitment without the breaker verifying.

The 2024 model year marks the i4 facelift, which is a significant boundary — a 2022 part sits in the pre-facelift generation and a 2024 part sits in the post-facelift generation, both on the G26 platform. Whether the rear cross member changed at that boundary is not something that can be stated with certainty here, so you must confirm with the breaker using both your registration and the donor car's registration before purchasing. Do not assume a pre-facelift unit will drop straight into a facelifted car without that check.

Trim level does not affect rear cross member fitment — the structural rear bodywork on the i4 is consistent across eDrive35, eDrive40, xDrive40 and M50 variants built on the same G26 platform for a given model year. You may find cosmetic differences such as diffuser or undertray finishes vary between trims, but the cross member itself is not trim-dependent. Match on platform, body style and model year rather than trim designation.

Yes, body style is the first consideration for rear structural components, and the i4 is exclusively a five-door Gran Coupé on the G26 platform — there is no saloon, estate or hatchback variant to confuse it with in the UK market. This means any G26 i4 rear cross member from the same generation should share the same body structure, unlike brands where multiple body styles share a nameplate. Always confirm the donor vehicle is also a G26 i4 Gran Coupé and not a related model such as the 4 Series Gran Coupé (G26 combustion), and check with the breaker if you are unsure whether those share pressing dimensions.

The i4 and the combustion-engined 4 Series Gran Coupé share the G26 platform, and on the surface the body structures look closely related. However, whether the rear cross member is an identical pressing or differs due to battery-floor integration on the i4 is not something that can be confirmed here as fact — this is exactly the kind of same-platform cross-variant question you must route to the breaker, quoting both registrations. Do not assume interchangeability without explicit confirmation from a breaker who can physically compare the parts.

Drive configuration does not alter the rear cross member for fitment purposes — it is a body structure component, not a drivetrain component, and the G26 i4 bodyshell does not change between rear-wheel-drive and all-wheel-drive variants at this level. Engine and drivetrain differences are among the factors that do not affect this part category, so you can disregard whether a donor car is RWD or AWD when assessing the cross member. Focus instead on generation, facelift status and confirming the match with the breaker against your registration.
