Peugeot 508 plug-in-hybrids revealed

New plug-in-hybrid Peugeot 508s get 225hp, 30 miles of pure-electric driving and CO2 emissions as low as 29g/km

Peugeot has unveiled plug-in-hybrid versions of its 508 saloon and SW estate that will go on sale later this year. Power comes from a 180hp 1.6-litre turbocharged petrol engine and an electric motor at the front providing 110hp for a total power output of 225hp.

Both models use the same 11.8kWh battery and take two hours to fully charge with a 7kW on board charger. The official figures show that the 508 hybrid returns 217mpg and produces 29g/km of CO2 emissions, with 30g/km for the SW estate and the same fuel economy.

For company-car drivers, both models sit in the 10% Benefit-in-Kind (BIK) tax band from April 2020. The 508 hybrid has four driving modes: Zero-emissions provides 100% electric drive for a maximum range of 33 miles for the saloon and 32 miles for the estate.

Sport combines the power from both the petrol engine and the electric motor to give maximum performance. Hybrid switches between the two while Comfort combines Hybrid mode with softer suspension for improved ride comfort.

Peugeot says it has engineered the battery packs so that they don’t take up any more space in the boot, so the saloon still retains 487 litres of boot space and the estate 530 litres. The 508 hybrid will be available in three trim levels: Allure, GT Line and GT. Top-spec GT cars get leather seats and a premium stereo. All versions get adaptive cruise control, a lane positioning aid and night vision.

Earlier in the year we drove a prototype of the 508 hybrid and found that the engine and electric motor “interact neatly to give quiet and punchy progress”. However, we did find the eight-speed automatic gearbox holds on to gears for too long and makes the engine sound thrashy – something we hope has since been resolved.
