Toyota has said only 20 of its Prius Plug-in Hybrids, a plug-in version of the third-generation Prius petrol-electric hybrid vehicle, will come to the UK.

The cars will be leased to public sector and business fleets as well as universities and research centres, for use in a demonstration programme aimed at collecting real-world driving data and helping in the development of a battery-charging infrastructure.

Toyota will analyse feedback from the fleet trials with the aim to beginning sales to the public in two years.

The details of the UK leases will be the announced closer to the cars' arrival in the middle of next year.
