Peugeot has unveiled a new performance version of its 508 upper-medium car, with a plug-in hybrid powertrain.

Badged the 508 Peugeot Sport Engineered, and heralding a new line of vehicles by that name, the new variant has a combined 360hp from a petrol engine and two electric motors, positioned at the front and rear to allow four-wheel drive.

Peugeot says the model, available as either a fastback or SW estate, is capable of driving for 26 miles on electric power alone on the WLTP cycle, and of combined fuel economy of 139mpg, and CO2 emissions of 46g/km.

The battery can be recharged in less than seven hours with a standard domestic socket, and in less than two hours with a 7kW wall box.

Peugeot says the Sport Engineered has the same interior space and load volume (above the floor) as the regular 508.

To enhance the driving experience compared with the regular car, the Sport Engineered features variable three-mode shock absorbers, a lower driving position, a widened front and rear track, 380mm diameter front brake discs with fixed four-piston callipers, and 20in alloy wheels with Michelin Pilot Sport 4S tyres.
