SPANISH energy giant Endesa is to test two prototype electric cars provided by vehicle manufacturer SEAT.

In the year-long trial, Endesa employees will drive a minimum number of kilometres each day in order to collect performance data to be analysed before the cars go into full production.

The pilot scheme, in Cataluna, will use an all-electric Altea XL Electric Ecomotive and a plug-in hybrid Leon TwinDrive.

The TwinDrive has a range of 52km and can travel at 120km/h when in electric mode, while the Altea has a Smartphone app allowing the driver to recharge the battery.
