MPG, running costs & CO2 Rating

4.0 out of 5

The latest Peugeot 508 follows in its predecessor's footsteps by vying for company fleet sales, but the French brand is keen for it to appeal to private buyers, too. A choice of fuel-efficient petrol and plug-in hybrid engines – the latter of which pack lots of power in PSE trim – look set to please both customer types, while other running costs should be well contained.

Peugeot 508 MPG & CO2

In the petrol camp, the PureTech 130 is said to return up to 50mpg, which would have been impressive even for a diesel a few years ago.

Officially, the 508 Hybrid can manage between 193.6mpg and 274.8mpg, but its real-world economy will depend entirely on how often you can charge the battery. Do so and you'll be able to make use of its 30 to 34-mile driving range at speeds of up to 84mph. Perhaps most importantly, its official 28-41g/km CO2 emissions figure means it qualifies for the lowest BiK payments of any version, costing company-car drivers less than half as much each year as the 1.5-litre BlueHDi diesel did.

The 12.4kWh battery pack takes under two hours to charge using a 7kW home wallbox, but it's worth noting that the 7.4kW on-board charger is a £400 option. Without this, the 508 PHEV will charge at a rate of 3.7kW. This is unlikely to be an issue if you plan to charge at home overnight, but will make a difference if you aim to top-up at public chargepoints.

The 508 PSE hybrid trades ultimate efficiency for performance but still offers a 34-mile electric range and a BiK rate that’s nearly a third as much as an Audi S4. You also get the 7.4kW on-board charger fitted as standard.

Those who cover more than around 12,000 miles per year might be best served by one of the diesel 508 models on the used market. Economy figures impress, with up to 64.1mpg possible for the 1.5-litre BlueHDi 130 diesel with the eight-speed automatic gearbox.

Petrol versions of the Peugeot 508 sit comfortably below the £40,000 mark, so won't cost more than the standard rate for annual VED (road tax). All PHEV models surpass that threshold and will cost almost £600 a year in the first five renewal years.

Insurance

The Association of British Insurers (ABI) has published official ratings for the latest Peugeot 508, with the entry-level PureTech 130 sitting in group 21. The plug-in hybrid is bumped up to group 29, while the range-topping 508 PSE sits in group 41 out of 50.

Servicing

Peugeot 508 owners will need to schedule a workshop visit at least annually, and Peugeot offers service packages to suit your specific circumstances. This will also help manage outgoing costs.

Warranty

Peugeot's warranty matches the three-year/unlimited-mileage policy offered by premium rivals, but still comes some way short of Kia’s seven-year/100,000-mile warranty or Hyundai’s five-year/unlimited-mile warranty.
