BMW G80 Buyer Guide: M3 (2020-present)
The G80 M3 is the current-generation BMW M3 saloon, sold in the UK from 2020. S58 twin-turbo I6 (evolution of B58 / S55 architecture). Manual or 8-speed M Steptronic auto. RWD only at launch; xDrive added 2022 on Competition variants. The first M3 Touring (G81) launched 2022. Phase 1 record: too new for mature failure consensus.
Quick verdict
The G80 M3 is the modern M3 buy if you want the latest hardware. Standard at £50,000-£60,000; Competition at £55,000-£67,000; xDrive Competition at £62,000-£75,000; CS at £95,000-£130,000. S58 engine has the B58 reliability story behind it but is too new for definitive long-term verdict. Charge pipe upgrade and oil filter housing gasket inspection are the early preventative items.
What is the BMW G80?
Most G80 M3 cars in UK classifieds in 2026 are 2020 to 2023 Competition examples with 15,000 to 50,000 miles, mostly ex-PCP. Manual transmission is rarer and commands a small premium. xDrive Competition is the modal daily-driver spec. M3 CS is firmly investment-grade. G81 M3 Touring (2022+) is the first-ever M3 estate and emerging on the used market.
Current-generation M3 saloon. S58 twin-turbo I6 evolved from the F80 / F82 S55. Manual or 8-speed M Steptronic auto. xDrive added from 2022. The first M3 Touring (G81) launched 2022, extending the M3 line into estate form for the first time. Controversial large-grille front-end design.

Pre-LCI vs LCI: what changed
BMW launched the G80 M3 in 2020 (saloon-only initially), with G82 M4 Coupe and G83 M4 Convertible launching the same year. xDrive added on Competition variants in 2022. G81 M3 Touring (first ever) launched July 2022. M3 CS limited edition launched 2023. No formal LCI yet. Latest engine: S58 twin-turbo I6 (480 standard, 510 Competition, 550 CS bhp). All on iDrive 8 platform.
Engines and which to choose
Only one engine: S58 twin-turbo I6 in three states of tune (480 / 510 / 550 bhp). Choice is about trim, transmission, and drivetrain (RWD vs xDrive). Phase 1 reliability: charge pipe upgrade is the early preventative.

| Brake wear (track-use compounded) | Moderate | Common | 20 to 50k mi | £800 to £1,500 |
| Note: G80 uses 8-speed M Steptronic auto, not DCT | Mild | Rare | 80 to 200k mi | £180 to £400 |
OEM plastic charge pipe (carried over pattern)
- Sudden boost loss
- Limp mode
- P0299
What to do about it: Aluminium aftermarket upgrade is standard early modification. £150-£300.
If ignored: Limp mode under boost.
UK repair exposure: £150 to £400.
Additional notes: Universal M-car upgrade. S58 inherits the pattern from B58 / S55.
Oil filter housing gasket leak
- Oil weep around oil filter housing
- Burning oil smell
What to do about it: Replace gasket at first sign. Same B58 / S58 pattern.
If ignored: Oil consumption rises.
UK repair exposure: £220 to £480.
Additional notes: Modular B-series wear pattern.
iDrive 8 software bugs
- Screen freezing or rebooting
- Apple CarPlay dropping
- Voice control unresponsive
What to do about it: BMW Remote Software Upgrade (RSU) addresses many bugs. Verify latest update applied.
If ignored: Cosmetic; car drives normally.
UK repair exposure: Up to £200 (free under recall if applicable).
Recall / TSB: BMW software updates 2021-2024.
Additional notes: Curved-glass twin display platform. Phase 1 reliability.
Brake wear (track-use compounded)
- Brake pad wear warning
- Reduced stopping performance
- Vibration through pedal under heavy braking
What to do about it: Replace pads and discs together; M-spec pads £800-£1,400 per axle.
If ignored: MOT failure; safety risk.

Additional notes: Track-used M3s wear brakes much faster. Carbon ceramics double the cost but last longer.
Note: G80 uses 8-speed M Steptronic auto, not DCT
- Standard M Steptronic auto service items
What to do about it: ZF 8HP M Steptronic service at 60,000 miles; fluid + filter £180-£300.
If ignored: Eventual transmission wear.
UK repair exposure: £180 to £400.
Additional notes: G80 dropped the F80's DCT in favour of ZF 8-speed M Steptronic; simpler long-term ownership.
MOT advisory patterns
Typical MOT advisories aggregated across UK F30 records. Not all will be present on any given car, but at 80,000+ miles you should expect at least two from this list:
- Brake disc and pad wear (M-car brakes wear fast)
- Tyre tread (staggered, performance compounds)
- Most G80s still under 6 years old; MOT data thin

Pre-purchase checklist (G80-specific)
Add these G80-specific checks on top of our generic UK used-BMW inspection checklist:
- Verify warranty status. Most G80 M3s are still under BMW manufacturer warranty or BMW Approved Used scheme.
- Confirm aluminium charge pipe upgrade fitted (standard M-car community early modification).
- Test all iDrive 8 functions. Curved-glass display can be fiddly. Software should be latest version (via BMW My app or BMW dealer).
- Verify M Drive memory modes work cleanly.
- Inspect carbon ceramic brake wear if fitted; £4,000+ premium when working, £800-£1,500 sensor or ceramic disc replacement is the long-tail.
- On manual cars: confirm clutch wear and gearbox engaging cleanly.
- On xDrive: test selectable RWD mode works correctly.
- On M3 CS: verify CFRP roof, bonnet, splitter all original. Semi-slick Cup 2 tyres should be present and within wear limits.
Buy, negotiate, or walk away
Buy
Full BMW service history, aluminium charge pipe fitted, all open campaigns completed, warranty status confirmed, no evidence of track use, M3 CS with full originality.
Negotiate
Original plastic charge pipe still fitted (£150-£300). Outstanding BMW campaign work. Oil filter housing gasket weeping. Brake pads near end of life.
Walk away
Modified car (stage 2+) without supporting service. M3 CS with no documented service. Track-day evidence without supporting service. Salvage or write-off.
Long-term ownership verdict
Too early to give a confident verdict; most G80 M3s are under 6 years old. Based on B58 / S58 architecture, 200,000+ miles is reasonable expectation. Main early preventatives: charge pipe upgrade, oil filter housing gasket inspection, ZF 8-speed M Steptronic service at 60,000 miles (simpler than F80 DCT). Phase 1 record.

Is the BMW G80 M3 reliable?
Early signals are positive. S58 engine is evolution of well-proven B58 with M-specific internals. No catastrophic systemic failures documented in the UK market to date. Phase 1: the reliability picture will sharpen over 2026-2028 as the fleet ages.
F80 M3 or G80 M3?
F80 (2014-2018) for value, the analog M-car character, and the option of a more conservative front-end design. G80 (2020+) for the latest hardware, xDrive option, more power, simpler M Steptronic transmission (vs F80 DCT). F80 in 2026: £22,000-£85,000. G80: £50,000-£130,000.
Is the G80 M3 ULEZ-compliant?
Yes. S58 is Euro 6d from launch.
Standard, Competition or CS?
Standard for the purist (manual, RWD, lighter); Competition for the modern fast-and-refined pick; CS for the special-edition lover. M3 CS (2023, ~1,700 units globally) is appreciating slowly.
Manual or 8-speed auto G80?
Manual is rare and the enthusiast pick. 8-speed M Steptronic (ZF 8HP M-spec) is the everyday-driver choice. Simpler long-term than F80 DCT.
G80 RWD or xDrive?
Pure RWD for the analog feel and lower weight. xDrive for the daily-driver convenience and selectable RWD mode for fun. xDrive was added 2022.
What's the G81 M3 Touring?
First ever M3 estate. Launched 2022. xDrive Competition only. 510 bhp. Available as 5-door wagon body. Used 2026 prices: £85,000 to £105,000.
How long will a G80 M3 last?
Too early to answer with confidence. Based on B58 / S58 architecture, 200,000+ miles is reasonable. The 8-speed M Steptronic is simpler long-term than the F80 DCT.
