2023 Peugeot 308 — UK Buyer’s Guide
Scope: 2023 UK retail year in UK. These figures are not automatically transferable to other countries or trims.
What the 2023 vehicle actually was
The UK’s third-generation Peugeot 308 offers a particularly wide set of ownership propositions under one nameplate. The smaller petrol and diesel cars appeal to conventional mileages, while 180- and 225-hp plug-in hybrids are designed for drivers who can actually charge. A 2023 308 advert needs the precise powertrain, not just the badge or “GT” trim label.
Peugeot’s launch specifications list 1.2-litre PureTech 130 petrol and 1.5-litre BlueHDi 130 diesel alternatives, alongside 1.6-litre-based PHEV models with an electric motor and 12.4-kWh battery. The plug-in ratings are WLTP claims from the relevant launch period; they cannot be used as an EPA distance or as a guarantee that a three-year-old vehicle will deliver that range.

Model-year distinction: Third-generation 308 hatchbacks remained in UK retail sales during 2023 with petrol, diesel and plug-in hybrid choices; the 308 SW estate is a separate body-style research record.
Strengths and ownership compromises
The driver-facing instrument position above Peugeot’s small steering wheel is an ergonomic feature that should be tried in person. The sloping hatchback rear and i-Cockpit layout may suit some drivers brilliantly and others not at all. For households with daily local journeys and home electricity, PHEV fuel savings depend on regular charging, not merely owning a plug.
Used buyer checks in 2026
On a used 308, document timing and service requirements for the exact petrol or diesel unit, check hybrid charging and battery health where applicable, and test the infotainment interface and driver-aid cameras. Avoid transplanting 308 SW estate load-space figures into this hatchback body record.
Alternatives and who should consider it
A Volkswagen Golf or Toyota Corolla Hybrid are sensible alternatives. The question is not which has an invented reliability score; it is which transmission, charging routine, seat position and regional specification meet the owner’s needs.
Factory specifications, test-cycle figures and original equipment are region- and grade-specific; verify the individual vehicle and official service eligibility using its VIN. This editorial is a buying framework, not a road test or an assertion of long-term failure rates.
