Overview
BMW M4 G82/G83 -Overview
The G82 is the second generation of the BMW M4 Coupé, unveiled in September 2020 and produced from November 2020.
It succeeded the F82 M4 (2014–2020) with a more powerful S58 engine, a larger vertically-oriented grille, and a chassis that shares its CLAR platform with the G80 M3. The G83 Convertible followed in summer 2021, featuring a folding fabric roof and additional body strengthening that adds approximately 145 kg over the Coupé. A 2024 Life Cycle Impulse (LCI) facelift brought a 20 PS power increase for Competition models, taking output to 530 PS.

Best & Worst Engines
Best Petrol Overall
S58B30T0 (3.0-litre twin-turbo, 480–530 PS)
“The S58 is widely regarded as one of the strongest inline-six turbocharged units BMW has ever produced. With a closed-deck design, forged crankshaft, and lessons learned from the S55 and B58, it delivers brutal power with surprising tractability. The 530 PS LCI Competition is the sweet spot -more power than the base car, but without the CSL's track-focused compromises.”
Who it's for: buyers who want the definitive modern M4 experience with the best balance of performance and reliability.
Best Value
M4 Competition (S58B30T0, 510–530 PS)
“The Competition is the M4 most buyers should choose -510 PS (pre-LCI) or 530 PS (LCI) is more than enough for road and track. It's available with either rear-wheel drive or the rear-biased M xDrive system, giving you the choice of purist driving or all-weather usability. The CSL's extra 20–40 PS isn't worth the significant price premium for most buyers.”
Who it's for: buyers who want the best all-round M4 without the CSL's track-focused compromises or price tag.
Most Expensive Failure
S58B30T0 (CSL, 550 PS)
“The CSL's 550 PS calibration pushes the S58 harder than any other variant, with boost pressure increased from 1.7 bar to 2.1 bar. The higher output places additional stress on the turbochargers, fuel system, and cooling system. A full engine replacement on a CSL can exceed £12,000 -the most expensive S58 to repair.”
Who it's for: collectors who want the ultimate G82 M4 and have the budget to maintain it.
Highest Risk
S58 (early production, 2020–2021)
“The S58 is generally reliable, but early production cars (2020–2021) may have higher rates of oil consumption between service intervals. Some owners have reported fuel pump and injector issues. The crank hub design was a concern on the S55 but appears less problematic on the S58. However, aftermarket sources suggest excessive kickdowns and high torque loads can still increase the risk.”
Who it's for: buyers who understand that early production cars may require closer monitoring.
Most Overlooked
G83 Convertible with M xDrive
“The G83 Convertible is often overlooked in favour of the Coupé, but it offers a unique experience -open-air motoring with 530 PS and xDrive traction. The folding fabric roof adds 145 kg and some structural compromise, but the S58's torque means you won't notice the weight penalty in everyday driving. It's the M4 for buyers who want both performance and the wind-in-the-hair experience.”
Who it's for: buyers who want the M4 experience with the roof down.
BMW M4 G82/G83 -Ownership Economics
The G82/G83 rule
A £6,000–£10,000 S58 recon against a £50,000–£90,000 M4 sits at 7–20% of the car's value -a repair decision, not a financial one. The 70% BMW threshold doesn't apply to cars of this value. However, the S58's oil consumption and potential fuel system issues mean that running costs can be significant -budget for regular oil top-ups and specialist servicing. The CSL's higher boost pressure (2.1 bar vs 1.7 bar) adds additional stress to the engine.
Key Takeaways
Which G82/G83 Costs Least To Own?
Base M4 (480 PS) -lowest state of tune, least stress on components.
Which G82/G83 Costs Most To Own?
M4 CSL (550 PS) -higher boost pressure, track-focused calibration, expensive parts.
Which G82/G83 Is Best Value?
M4 Competition (510–530 PS) -the sweet spot in the range, strongest residuals, the one enthusiasts want.
