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 diesel and petrol engines – the latter of which pack lots of power – look set to please both customer types, while other running costs should be well contained.

Peugeot 508 MPG & CO2

Those who cover more than around 12,000 miles per year might be best served by one of the 508's diesel engines. Economy figures range from 50.3mpg for the 2.0-litre BlueHDi 180, to 62mpg for the less powerful 1.5-litre BlueHDi 130 diesel with the eight-speed automatic gearbox option (six-speed manual cars manage up to 63.6mpg).

The BlueHDi range is very economical; especially the 1.5-litre found in the 130 version, while the BlueHDI 180 has higher emissions, but it's also RDE2 compliant, meaning its BiK rating is 4% lower than for an older diesel with the same CO2 emissions.

In the petrol camp, the PureTech 180 should be affordable for company-car drivers, thanks to a fairly low BiK bracket, while returning up to 44mpg. This figure – along with the 42.2mpg claimed for the range-topping PureTech 225 – is impressive for a car with such a strong turn of speed.

Officially, the 508 Hybrid can manage between 166.2mpg and 235.4mpg, 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 39-mile driving range at speeds of up to 84mph. Perhaps most importantly, its official 29g/km CO2 emissions figure means it qualifies for the lowest BiK payments of any version, costing company-car drivers in the 40% tax bracket virtually half as much each year as the 1.5-litre BlueHDi diesel. It's also exempt from the London Congestion Charge.

The 11.8kWh battery pack takes under two hours to charge using a 7kW home wallbox, but it's worth noting that the 7kW on-board charger is a £300 option. Without this the 508 PHEV will charge at a rate of 3.7kW.

Most versions of the Peugeot 508 sit comfortably below the £40,000 mark, so won't cost more than £150 for annual road tax. Those that surpass the threshold will cost £475 (£465 for the Hybrid) in the first five renewal years.


The Association of British Insurers (ABI) has published official ratings for the latest Peugeot 508, with the entry-level BlueHDi 130 sitting in groups 22-24. The range-topping BlueTech 225 models sit in group 32 out of 50.


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.


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