Second Hand BMW i7 Subframe

The BMW i7 is a single-generation model that launched in 2022, so all UK cars share the same G70 platform to date. Because the model is relatively new and mid-generation changes are still emerging, confirm with the breaker that the donor car's build date matches yours before buying.

Both fall within the current G70 generation (2022 onwards), so they share the same fundamental platform and subframe design. That said, BMW can introduce running changes during a production run, so always give the breaker your full registration so they can cross-reference the exact part number against their donor vehicle.

The i7 M70 xDrive is a significantly higher-output variant with a different powertrain and greater vehicle weight, which can mean uprated suspension and braking components including a different front or rear subframe specification compared with the xDrive60. Trim or badge level alone does not affect fitment for cosmetic reasons, but power and weight differences genuinely do, so confirm with the breaker that the donor car is the same variant as yours before purchasing.

Yes — the front and rear subframes are completely different parts with different mounting points and functions, so you must specify which one you need when contacting a breaker. The front subframe carries the steering and front suspension, while the rear subframe supports the rear suspension and, on the i7, rear motor components, so a mix-up would leave you with a part that cannot be fitted.

The i7 shares its G70 body generation with the combustion-engined 7 Series (also 2022 onwards), but the i7's rear subframe in particular is engineered around its electric motor and battery architecture, which differs substantially from petrol and diesel variants. It is possible some front subframe sections are shared, but this is something you must confirm with the breaker against both registrations rather than assume, as fitting the wrong variant could compromise safety.

The i7 only went on sale in the UK from 2022 and is a premium, low-volume vehicle, so breaker stock will be limited compared with mainstream models. Your best approach is to use a marketplace like Findapart to get quotes from multiple dismantlers simultaneously, and when you make contact, give them your registration and VIN so they can confirm the exact specification of their donor car matches yours.
