Summary

A high-performance plug-in hybrid, the Peugeot 508 PSE (Peugeot Sport Engineered) is the flagship version of the Peugeot 508, offered in both liftback and estate body styles.

As well as the car’s sportier bodywork that the manufacturer says improves aerodynamics, the Peugeot 508 PSE produces more than double the power of the standard 508 saloon, thanks to its 355hp plug-in hybrid powertrain which combines a petrol engine with two electric motors.

Peugeot says that the 508 PSE can complete a 0-60mph sprint in 5.2 seconds, and travel a maximum of 26 miles on just electric power.

This is the most expensive model that Peugeot has ever sold, and by current plug-in hybrid standards, that all-electric range is middling. The cheaper Volvo V60 Recharge comparatively has an electric range of 54 miles.

Despite its flaws, a number of outlets argue that the 508 PSE has some definite charms – Carwow explains that this sports saloon and estate is “extremely handsome, fast and comfortable”, while Auto Express says that this is “a versatile machine loaded with kit that also boasts strong efficiency”.

If you find this flagship performance model intriguing, you may be deterred by its price tag. Parkers comments that, “with a list price of more than £50,000, the 508 PSE is a tough sell for private buyers”.

A facelifted version of the 508 PSE arrived in the second half of 2023.

As of January 2025, the Peugeot 508 PSE holds a New Car Expert Rating of B, with a score of 66%. Being a plug-in hybrid, it has very low official CO2 emissions. Its safety rating is also good, but running costs are high and the 508 range has a poor reliability record.

Running costs for the Peugeot 508 PSE are a bit of a mixed bag, according to whole-life cost data provided exclusively to The Car Expert by our technical partner, Clear Vehicle Data.

Being a plug-in hybrid, fuel economy and CO2 emissions look great on paper, but that’s due to the woeful EU/UK goverment lab tests that are completely useless at measuring a plug-in hybrid…

Battery range also looks woeful, but it’s fairly average for a plug-in hybrid. A fully electric car of similar size, by comparison, will usually have about 250-300 miles of range.

Insurance costs are expensive compared to the regular 508 models, while servicing and maintenance costs over the first five years are merely average.
