Overview

BMW M3 G80/G81 -Overview

The G80 is the sixth generation of the BMW M3, a high-performance sports saloon unveiled in September 2020 and based on the G20 3 Series platform.

For the first time in M3 history, a Touring (estate) variant -the G81 -was introduced in June 2022. Both body styles are powered exclusively by the S58 3.0-litre twin-turbocharged inline-six engine, available in outputs ranging from 480 PS (473 bhp) to 530 PS (523 bhp), with a limited-run M3 CS producing 550 PS (543 bhp). Transmission options include a 6-speed manual (base model only) and an 8-speed M Steptronic automatic, with M xDrive all-wheel drive available on Competition models. A 2024 Life Cycle Impulse (LCI) facelift brought a power increase for xDrive models to 530 PS.

Best & Worst Engines

Thin-Data Summary

Thin-Data Fallback mode -exactly one paragraph: The S58 engine is a masterpiece of modern M engineering -robust, over-engineered for its stock outputs, and widely regarded as one of BMW's most reliable performance engines. The sweet spot in the range is the Competition xDrive with the LCI power bump to 530 PS -blistering performance (0–100 km/h in 3.5 seconds) with the security of all-wheel drive and the option of rear-wheel-drive-only drifting. The base manual M3 (480 PS) is the purist's choice, offering the last chance at a stick-shift M3 before electrification takes over. The M3 CS is a limited-run track weapon with 550 PS, but it commands a significant premium and is harder to find. The G81 Touring is the most practical M3 ever built, combining supercar performance with estate car utility -and it's only available in Competition xDrive guise. All S58 variants are reliable when properly maintained, though cooling system health and regular oil monitoring are essential.

The G80/G81 rule

A £10,000 S58 recon against a £50,000 M3 sits at 20% -well within our 70% BMW threshold. Even the M3 CS's £16,000 recon against a £80,000 car is just 20%. Unlike older M cars, the G80's high retained value means engine replacement is almost always financially viable. Value the car first -but on a modern M3, a recon is usually a repair decision, not a financial one.

Key Takeaways

  • Which G80/G81 Costs Least To Own?

    Base M3 (480 PS) -cheaper to buy, simpler manual transmission, but lower performance.

  • Which G80/G81 Costs Most To Own?

    M3 CS -limited production, track-focused components, higher replacement costs.

  • Which G80/G81 Is Best Value?

    M3 Competition xDrive -the sweet spot of performance, traction, and daily usability.
