The Complete Guide: Best & Worst Years of McLaren 720S
(Reliability, Issues & Buying Advice)
🔍 What is the McLaren 720S & Why Model Years Matter
The McLaren 720S is a British mid-engine supercar powered by the M840T 4.0L twin-turbo V8, delivering 710 bhp and 568 lb-ft torque. It features the revolutionary Proactive Chassis Control II hydraulic suspension and carbon fiber Monocage II. However, each production year brought running changes, meaning “best and worst years” directly affect ownership costs, reliability, and resale value. Early builds (2018) suffered teething problems; later iterations enjoy refined electronics and mechanical durability.
Why do years differ in quality? McLaren continuously updated software, hydraulic accumulators, steering components, and infotainment hardware post-2019. Knowledge of 720S model year weaknesses can save you thousands in out-of-warranty repairs.
📅 Types of McLaren 720S Model Years (Generations)
Though no official “Gen 1/Gen 2”, experts split into three phases: Early Build (2018–early 2019) – high risk; Transition Build (late 2019–2020) – partial improvements; Mature Build (2021–2022) – most dependable. Additionally, you have Coupé & Spider body styles, but the year remains the primary factor. The 2023+ 750S replaced the 720S.
🛠️ How to Evaluate a Used McLaren 720S (Checklist)
When shopping, how to avoid a troublesome 720S? Follow this expert protocol:
- ✔️ Verify VIN & production date (avoid VINs below 5000 for 2018/2019).
- ✔️ Request service history: check for hydraulic accumulator replacements, steering rack TSBs.
- ✔️ Perform a suspension leak-down test (early PCCM issues).
- ✔️ Scan for electronic gremlins (IRIS screen, HVAC).
- ✔️ Insist on a PPI (Pre-Purchase Inspection) by a McLaren specialist.
Is it safe? The carbon fiber tub provides FIA-level safety, but high-speed crashes demand structural integrity. Advantages include exceptional crash protection, while disadvantages involve exorbitant repair costs after minor incidents.
✅ Advantages of McLaren 720S
- 🔥 Mind-blowing performance (0-60 in 2.7s)
- 🚀 Advanced hydraulic suspension = ride/handling duality
- 🎨 Stunning dihedral doors & visceral drama
- 📈 Later years hold value better (2021+)
- 🏁 Track capability with daily usability
⚠️ Disadvantages & Risks
- 💸 High depreciation on early models (2018-2019)
- 🔧 Costly repairs: hydraulic suspension failure ≈ $12k+
- 📱 Unreliable infotainment (pre-2020)
- 🔋 Frequent battery drain issues
- 🛞 Limited service network compared to Porsche/Ferrari
⭐ Best Years for McLaren 720S (Recommended)
2021 McLaren 720S
Why it’s best: Resolved hydraulic suspension reliability, improved IRIS 2.0 touchscreen with faster response, upgraded turbo wastegate actuators, and revised engine mounts reduce vibration. Fewer electrical complaints. Also benefits from standard MSO Defined upgrades.
➕ Pros: Peak reliability, minimal TSBs, strong resale, mature software calibration.
2022 McLaren 720S
Final year before 750S: All known bug fixes implemented, includes latest steering rack revisions, recalibrated Proactive Chassis Control for better road feel, and most cars still under factory warranty. Low failure rate for major components.
2020 (Late Production)
Mid-cycle improvement: After chassis numbers from 2020.5, the 720S reliability significantly improved. Avoid very early 2020 build dates. Late 2020 features upgraded accumulators, better A/C compressor, and fewer errors.
⚠️ Worst Years for McLaren 720S (Avoid if possible)
2018 McLaren 720S
First production year nightmares: Frequent hydraulic suspension accumulator failures (leaks & knock), premature turbocharger issues, delaminated engine coolant pipes, unexplained limp mode, screen freezes, and steering rack clunking. Many 2018 units required multiple warranty repairs.
🔻 Common complaints: “Suspension fault” warnings, unreliable track mode.
Early 2019 (VIN under 10000)
Still problematic: While slightly better, early 2019s share hydraulic and electronics gremlins, including infotainment blackouts. Not all service campaigns completed. Only consider with full service history and recent accumulator replacement.
📊 Model Year Comparison: Reliability, Cost & Verdict
| Model Year | Reliability Score | Common Issues | Verdict |
|---|---|---|---|
| 2018 | 3/10 | Hydraulic suspension, turbo failures, electronics | AVOID unless deep discount + warranty |
| 2019 (early) | 4/10 | Accumulator leaks, steering rack, software glitches | Proceed with caution, PPI mandatory |
| 2019 (late) | 6/10 | Occasional coolant pipe issues, improved but not perfect | Fair, budget for extended warranty |
| 2020 (post-June) | 7.5/10 | Rare suspension failures, minor electronic freezes | Good value, recommended |
| 2021 | 9/10 | Very few systemic issues, stable IRIS, robust drivetrain | BEST YEAR – premium choice |
| 2022 | 9.2/10 | Isolated minor trim issues, overall peak maturity | Excellent, top reliability |
🏁 Use Cases: Daily Driving, Track & GT Cruising
Is McLaren 720S a good daily driver? Later years (2021+) can handle daily duties with adequate ground clearance (though speed bumps are tricky). Fuel economy averages 15 MPG, advantages include surprising comfort in Comfort mode, disadvantages include high tire/brake wear. For track use, all years perform exceptional, but early models risk overheating components. Best for weekend supercar touring and occasional track days if you have warranty backup.
🛡️ Is it Safe to Buy a Used High-Mileage 720S?
Safety wise, the carbon fiber monocoque is extremely strong, but maintenance history is key. A high-mileage 2021+ with full dealer records is safer than a low-mileage 2018 that sat with hydraulics aging. How to ensure a safe purchase? Always buy from a reputable dealer with a warranty. Avoid salvage titles (structural repairs compromise safety).
🔄 Advantages vs Disadvantages by Model Year
Best years (2021–2022): Advantages include reliability, resale value, modern refinement. Disadvantages: higher acquisition cost.
Worst years (2018–early 2019): Advantages: cheaper entry price (up to $30k less than 2021). Disadvantages: high likelihood of $5k–$15k repairs, unpredictable electronics, and frustrating ownership experiences.
