Peugeot 308 III (P51) (2021 – 2025)

Reliability score : 7.2/10

The Peugeot 308 Generation III (Internal codes: P51 for hatchback, P52 for SW estate) represents a major upmarket shift for the French manufacturer. Introduced in 2021, it was the first model to feature Peugeot's new shield logo. Built on the heavily updated EMP2 V3 platform, it boasts a striking, aggressive design, a highly modernized 'i-Cockpit' interior with premium materials, and the new 'i-Connect Advanced' infotainment system. Positioned at the upper end of the mainstream C-segment, it aims to rival premium competitors. A major highlight of this generation is its multi-energy platform, allowing it to offer traditional internal combustion engines (ICE), plug-in hybrids (PHEV), mild hybrids (MHEV, introduced in 2023), and a fully electric version (e-308, introduced in 2023).

✅ Strengths

Stunning exterior design and strong road presence
High-quality interior materials, rivaling premium German brands
Excellent chassis tuning offering a great balance of comfort and agility
Wide variety of powertrains (Petrol, Diesel, MHEV, PHEV, EV)
Advanced and customizable 3D i-Cockpit display
Excellent fuel economy on PHEV and Diesel models

⚠️ Weaknesses

Rear legroom is cramped compared to class rivals (VW Golf, Honda Civic)
The i-Cockpit driving position (small steering wheel below dials) does not suit all body types
Infotainment system (i-Connect) can be laggy and prone to black screens on early 2021-2022 models
Lingering reliability concerns over the 1.2 PureTech (wet belt) and 1.5 BlueHDi engines
Intrusive lane-keeping assist that needs to be disabled every time the car starts

🎯 Verdict

The Peugeot 308 III is undeniably one of the most attractive and premium-feeling hatchbacks in its class. However, buying one requires careful powertrain selection. Avoid the standard 1.2 PureTech (110/130 hp) unless it has a flawless, documented service history with frequent oil changes, due to the wet timing belt design. Negotiate on the 1.5 BlueHDi, ensuring the camshaft chain has been upgraded to 8mm and the AdBlue system is functioning perfectly. Buy the newer 1.2 Hybrid 136 (MHEV) which features a much more reliable timing chain, or the 1.6 PHEV models which offer a solid engine and great efficiency, provided the software is fully up to date.
