The G20 Saloon and G21 Touring have been on sale since 2019, with the LCI facelift in 2022. Both bodies share front seat shapes exactly - only the rear differs.
Fit facts at a glance
| Fact | Value |
|---|---|
| Bodies | Saloon (G20), Touring (G21) |
| Front seat | Bucket-style; Sport, M Sport, M Sport Pro cuts |

What to look for on the listing
- The listing must say “airbag-compatible” - non-negotiable for the 3 Series.
- Confirm the trim: M Sport bolsters are deeper than Sport, and covers are cut differently.
- Touring and Saloon share front covers; rear covers also cross-fit given the same 40/20/40 split.
- If your car has ventilated seats, look for perforated cover panels or skip covers on those seats entirely.
Frequently asked questions
Are M3 sports seats compatible with universal covers?
No. The M3 uses carbon-shelled buckets with integrated headrests. Universal covers cannot install; only specialist M3-specific covers exist and choice is limited.
Do 330e PHEV covers differ from petrol?
No. The plug-in loses boot space but the front and rear seats are identical to the pure-ICE cars. Same cover set fits.
