Peugeot 508 II (R8) (2018 – 2025)

Reliability score : 7.2/10

The Peugeot 508 II (Internal code: R8) marks a radical departure from its predecessor, transforming from a traditional three-box sedan into a striking, low-slung fastback (and SW estate) with frameless doors. Positioned as a premium-leaning D-segment contender, it boasts the futuristic i-Cockpit, exceptional chassis dynamics, and a bold design. A major facelift in 2023 introduced the new Peugeot shield logo, a wider grille integrating the matrix LED headlights, and an updated infotainment system (Peugeot i-Connect Advanced). While it sacrifices some rear headroom and trunk space for style, it remains one of the most engaging cars to drive in its class. This guide focuses heavily on the petrol (PureTech/THP) variants as requested, while exhaustively covering the diesel (BlueHDi) and Plug-in

✅ Strengths

Stunning exterior design and fastback silhouette
Exceptional chassis tuning: perfect balance of comfort and sharp handling
High-quality interior materials and futuristic i-Cockpit design
Excellent 1.6 PureTech and 2.0 BlueHDi engines
Practical hatchback tailgate (unlike the previous generation's trunk)

⚠️ Weaknesses

1.2 PureTech 130 engine reliability (wet belt issues)
1.5 BlueHDi camshaft chain and AdBlue system failures
Rear headroom and rear visibility are compromised by the sloping roofline
Infotainment system (pre-2023 facelift) is sluggish and visually dated
PHEV versions lose trunk space and add significant weight

🎯 Verdict

⚖️ Final Verdict The Peugeot 508 II is a triumph of design and driving dynamics, proving that mainstream brands can still build highly desirable D-segment cars. However, its reliability is heavily dependent on the engine choice. If you want Petrol: The 1.6 PureTech (180 or 225 hp) is the absolute sweet spot. It is robust, powerful, and perfectly matches the car's GT character. Avoid the 1.2 PureTech 130 at all costs due to its catastrophic timing belt design, unless you are buying a very late model or are prepared for meticulous, preventative maintenance. If you want Diesel: Seek out the 2.0 BlueHDi (160/180). It is a phenomenal highway cruiser. The 1.5 BlueHDi should be approached with caution due to the camshaft chain issue (ensure it has the 8mm update). If you want PHEV: It is a solid choice for tax purposes and daily commuting, but be prepared for potential electronic gremlins and ensure the vehicle is still under warranty if possible.
