MINI Cabrio III (F57) (2015 – 2023)

Reliability score : 8.6/10

The MINI Cabrio Generation III (F57), introduced in late 2015 for the 2016 model year, represents a monumental shift for the brand. Built on BMW's UKL1 front-wheel-drive architecture, it grew in size, refinement, and most importantly, reliability. Leaving behind the problematic 'Prince' engines of the R57 generation, the F57 adopted BMW's modular B-series engines (B38 3-cylinder and B48 4-cylinder). This generation received two major updates: LCI 1 in 2018 (Union Jack taillights, dual-clutch transmissions replacing torque converters on some models, upgraded infotainment) and LCI 2 in 2021 (revised front fascia, digital instrument cluster). The F57 is widely considered the most dependable MINI convertible ever built, offering premium build quality, excellent driving dynamics ('go-kart feel'

✅ Strengths

Massive reliability improvement over the previous R57 generation (thanks to BMW B-series engines).
High-quality interior materials and excellent infotainment system (iDrive based).
Outstanding driving dynamics, precise steering, and strong chassis rigidity for a convertible.
Unique soft-top design with a built-in sliding sunroof function.
Strong resale value and timeless design.

⚠️ Weaknesses

Upper engine mounts are a known weak point across the entire UKL platform.
Rear visibility is extremely poor when the roof is folded down.
Trunk space is minimal (160-215 liters) and access is restricted.
Firm ride quality, especially on Cooper S/JCW models with 17 or 18-inch wheels.
Soft-top fabric can show wear marks/creases at the folding points over time.

🎯 Verdict

The MINI Cabrio F57 is a highly recommended purchase, provided you opt for the petrol engines (B38 or B48). BMW finally cured the chronic engine issues that plagued the previous generation, making the F57 a genuinely reliable premium convertible. The Cooper (1.5L) is the sweet spot for daily driving, while the Cooper S (2.0L) offers genuine hot-hatch thrills with the roof down. When buying used, your primary focus should be on the condition of the soft-top fabric and mechanism, and verifying that the notorious upper engine mount has been replaced. Avoid the diesels unless you do extensive highway driving, as they are prone to EGR and DPF issues.
