Fitment questions
Does the BMW i4 have a crankshaft?
No — the BMW i4 is a fully electric vehicle and has no internal combustion engine of any kind, so it has no crankshaft. The drive comes entirely from one or two electric motors depending on the variant (eDrive40 or M50), none of which use a crankshaft, camshaft, or any reciprocating engine components. If you're searching for a crankshaft, you may have the wrong vehicle, or you might be thinking of a different BMW model such as the 4 Series (G22/G26) which shares the i4's platform but uses petrol or diesel engines.
I need a crankshaft for my BMW i4 — what part should I actually be looking for?
Because the i4 is battery-electric, the rotating assembly you might be thinking of is most likely the electric motor rotor, a drive shaft (half shaft), or possibly a rear differential unit on M50 all-wheel-drive models — none of these are crankshafts. If your car has a fault related to vibration or drive, a breaker or EV specialist can help identify the correct electric drivetrain component. It's worth having your registration and VIN ready, as electric drivetrain parts on the i4 can vary between the eDrive40 (single motor, rear-wheel drive) and M50 (dual motor, all-wheel drive) variants.
Could the BMW i4 ever have had a crankshaft fitted as an option or on a special variant?
No — every variant of the BMW i4, across its entire production run from 2021 onwards, is fully electric with no combustion engine option whatsoever. There are no hybrid, mild-hybrid, or petrol variants of the i4; it is an EV-only model built on BMW's CLAR platform adapted for electric drive. No crankshaft was ever fitted to any i4 in any market, so no used or genuine crankshaft for an i4 exists.
I've seen a crankshaft listed online described as fitting a BMW i4 — is that correct?
That listing is almost certainly mislabelled or referring to a different BMW model, such as the G22 4 Series coupe or G26 4 Series Gran Coupe, which share body architecture with the i4 but use petrol or diesel engines that do have crankshafts. The BMW i4 (G26 EV) has no combustion engine and therefore no crankshaft exists for it. If you've found a listing, check the exact model code with the seller before purchasing — a G26 petrol crankshaft will not be relevant to an i4 in any way.
