⚠️ The M4 rule - the coupe premium: an S55 recon at £7,000–£10,000+ against a £30,000–£40,000 F82 is 18–33% - ✅ safe on most examples. Against a £60,000 G82, an S58 recon at £7,000–£10,000+ is 12–17% - ✅ safe. The M4's values are strong enough to justify engine work.
★★★★☆ - the S55 is proven but the crank hub is the Achilles heel; the S58 is widely regarded as BMW's most reliable modern performance engine
S58B30 (G82) - the latest M engine is proving exceptionally robust
S55B30 (F82) - crank hub spin (especially on tuned cars)
F82 M4 Competition with S55 - 444 bhp, proven engine, depreciated, and the sweet spot in the range
G82 M4 Competition with S58 - 503 bhp, xDrive available, the most reliable M engine
£7,000–£10,000+ reconditioned, supply only [BMW-QUOTE]

🏆 The Performance Coupe - the M3's two-door sibling with the same engine DNA
One-line verdict:
The M4 is the M3's coupe sibling - the same engines, the same risks, and the same rewards. The S55 is proven but the crank hub is the Achilles heel; the S58 is widely regarded as BMW's most reliable modern performance engine. Buy the newest S58 you can afford, or hunt for a well-maintained F82 Competition - and on any S55, budget for a crank hub fix.

The six most common failure patterns across the M4 range - symptoms, costs and urgency.
01The defining F82 M4 issue - the crank hub is not keyed to the crankshaft and relies on friction alone. Under high load (especially on tuned cars), it can spin, causing piston-to-valve contact. Affects F82/F83 M4 (2014–2020). £7,000–£10,000+ recon. Preventative fix: £1,500–£3,000.
Learn more
02The S55's timing chain tensioner can wear, causing rattling on cold start. Skipping oil changes or using the wrong oil accelerates wear. Affects F82/F83 M4.
Learn more
03The rocker cover, oil filter housing and sump gaskets can perish, leading to oil drips. Affects F82/F83 M4. Check for oil drips on any used example.
Learn more
04The S58 engine in the G82 has been reported to consume oil at a higher rate than expected. Some owners require more frequent oil top-ups. Regular oil level monitoring is essential.
Learn more
05The S58's turbochargers and cooling system can experience issues under sustained high-load use. Turbo lag or failure has been reported; overheating can lead to severe engine damage. Regular maintenance is essential.
Learn more
06Not an engine failure - but common non-engine M4 enquiries. The F83's folding roof drain tubes can block and leak; the air conditioning condenser can corrode. Check both on any F83.

Interesting insight: The M4 generates a different kind of enquiry than the rest of the BMW range - owners are enthusiasts doing due diligence on specific known issues (S55 crank hub) rather than families facing unexpected failures. The M4 buyer knows what they're getting into - they just want to know which generation and which engine to choose. (Editorial synthesis - specialist sense-check before publishing.)
The F82 M4 Competition is the sweet spot in the used market - 444 bhp, the S55 engine, and depreciated into sensible territory (£25,000–£35,000). The crank hub is the only caveat - budget for a hub fix (£1,500–£3,000) or buy one that's already been done. A 2017+ facelift car with the Competition package is the one to buy. (Editorial synthesis.)
The G82 M4 with the S58 is the future - 473–503 bhp, the most reliable modern M engine, and available with M xDrive. Too new for volume reliability data, but the S58 is proving exceptionally robust in the M3/M4. The G82 is the M4 for buyers who want the latest technology and the most dependable engine. (Editorial synthesis.)
Editorial Pull-Quote
“If you buy one M4 based on this page, buy a 2017+ F82 M4 Competition with the S55 - it's the sweet spot in the range: 444 bhp, the LCI updates, and depreciated into sensible territory. Just budget for a crank hub fix (£1,500–£3,000) or buy one that's already been done. If your budget stretches, the G82 with the S58 is the most reliable M4 ever made - and the M xDrive version is devastatingly fast.”

Fitting a BMW M4 engine typically takes 16–20 hours at £65–£95/hr (independent) or £110–£160/hr (London/SE dealer) [BMW-QUOTE]. The M4 rule - pay to play: A £7,000–£10,000+ S55 recon against a £30,000 F82 sits at 23–33% - ✅ safe. Against a £60,000 G82, the same recon is 12–17% - ✅ safe. The M4's values are strong enough to justify engine work - but factor in preventative maintenance (crank hub fix £1,500–£3,000) as part of the purchase cost. Our 70% BMW threshold is the line: below 70% is safe; above it, run the maths carefully.

From the original M10 to today's advanced B-series, explore how engineering, emissions and performance shaped every generation of 3 Series engines.
BMW launched the M4 as the coupe sibling to the F80 M3, replacing the E92 M3. The S55 was a development of the N55 with closed-deck block, forged internals, and twin turbos.
The S55 is proven and powerful (425–444 bhp), but the crank hub is the Achilles heel. The Competition (444 bhp) is the sweet spot; the GTS (493 bhp) is the ultimate F82.
The second-generation M4 arrived on the CLAR platform - bigger, more powerful, and with the S58 engine from the G80 M3. The S58 is widely regarded as BMW's most reliable modern performance engine.
The S58 is the most reliable M engine ever made. The G82 is available with rear-wheel drive (473 bhp manual) or M xDrive (503 bhp auto). The G82 is the M4 for the modern era - buy it with confidence.
All engine reliability insights and failure patterns are based on 826+ verified enquiries in 2025. Data covers the UK market. [BMW-VERIFIED]
Different buyers, different priorities. Here is our verdict on who the BMW M4 is perfect for - and who should think twice.
The M4 is built for this - 425–503 bhp, rear-wheel-drive (or xDrive), and one of the finest coupe chassis in the world. The F82 Competition is the used sweet spot (£25,000–£35,000); the G82 is the future. Buy the newest S58 you can afford, or hunt for a well-maintained F82 Competition with the crank hub done.
The F82 M4 GTS is a future classic - 493 bhp, water injection, and just 803 produced worldwide. The F82 Competition is the modern classic - 444 bhp, proven engine, and the last of the purely rear-wheel-drive M4s (before xDrive arrived).
The M4 is a daily-drivable performance coupe - the F82 is surprisingly practical with a large boot and usable rear seats; the G82 is more refined and comfortable. The F82 is the better weekend car; the G82 is the better daily driver.
The M4 is one of the best track-day cars you can buy - the F82's S55 is proven on track; the G82's S58 with xDrive is devastatingly fast. Budget for cooling upgrades and crank hub prevention on the F82.
The F82 M4 is a modern classic - the Competition is the sweet spot, the GTS is the investment. Both are worth proper investment; values are holding strong. The G82 is the future classic - buy it now and enjoy it.
