A NEW series of electrified models has been announced by Citroen with updates to the e-C4, the e-C4 X and the C5 Aircross.

The new models are called the e-Series line-up and include more style and technology plus the use of additional recycled materials.

All three models share key design elements such as a black bi-tone roof and black alloy wheels as well as e-Series exterior badging.

Sitting at the top of the range for both e-C4 and e-C4 X e-Series versions the vehicles come with the new My Citroen Drive Plus infotainment system and keyless start as well as heated front seats and an upgraded Citroen HiFi system.

E-Series variants will be available with the existing 136hp 50kWh powertrain with a range of up to 222 miles, as well as the new 156hp 54kWh version with a range of up to 260 miles.

The C5 Aircross e-Series editions now comes with Highway Driver Assist, an opening panoramic glass sunroof, and heated front seats.

The e-Series models will be available with the 225 Plug-in Hybrid powertrain, as well as the new Hybrid 136, which uses a 136hp PureTech petrol engine with 48V battery technology, alongside a new electrified dual-clutch e-DCS6 gearbox and a 21kW electric motor - reducing CO2emissions by up to 15 per cent.

E-Series versions also come with Citroën's Dark Chrome colour pack, which is applied to the front bumper inserts and the Airbump panels.

Prices for the e-Series e-C4 and e-C4 X start from £36,295 while the C5 Aircross e-Series PHEV costs from £38,375.

The prices of the other e-Series models are still to be confirmed and Citroen says the new cars will be available from July.
