Used BMW i7 Rear Cross Member

The BMW i7 (G70 platform) launched in the UK in 2022 and remains in production as of 2025, so all current i7s share the same generation and platform. The rear cross member is a structural body component tied directly to the G70 platform, meaning parts from anywhere within that 2022-onwards production run are broadly from the same family. Always confirm the exact part number with the breaker against your registration before purchasing, as minor pressing or specification changes can occur mid-production without a formal facelift announcement.

Both the 2023 and 2024 BMW i7 sit on the same G70 platform within the same generation, so they are in principle the same body architecture. However, mid-generation pressing or specification changes can happen without a publicised facelift, and the i7's rear structure can carry additional reinforcements depending on configuration. Confirm the part against your specific registration with the breaker before committing to a purchase.

The BMW i7 is offered in both standard wheelbase and extended long-wheelbase (xL) body variants, and these have meaningfully different rear underbody dimensions and structural geometry. A rear cross member from a standard i7 is very unlikely to be a straight swap onto an xL car, even though both share the G70 platform. Always tell the breaker exactly which wheelbase variant your car is — confirm against your registration — before they source a part.

Trim level and drivetrain designation (such as xDrive60, xDrive50, or M70) do not affect the rear cross member, as this is a structural platform component rather than a trim-specific panel. You may find cosmetic differences in surrounding components depending on specification, but the cross member itself is common across trim levels on the same wheelbase variant. Just make sure the wheelbase and body configuration match between donor and recipient car.

The i7 shares the G70 platform with the combustion-engined 7 Series (i740, 760 etc.), and in many cases structural underbody components are shared across the range. However, the i7's battery pack and its mounting provisions can influence rear underbody pressing specifications, so a part that looks identical may have subtle differences. This is exactly the kind of cross-variant question to route to your breaker with both registration numbers so they can compare part numbers directly.

Give the breaker your full registration number so they can identify your exact wheelbase, body configuration, and build date — these factors matter far more than engine or trim for a structural rear component like this. Ask them to cross-reference the part number from their donor vehicle against the one listed for your car, as mid-production changes can catch buyers out. Never rely on year alone; always verify through the breaker against your specific VIN or registration.
