Toyota has revealed its second generation Prius Plug-in. The new car can now achieve a higher maximum EV speed of 84mph, and can also cover twice the distance of its predecessor, more than 30 miles. The Prius Plug-in also debuts a world first range-extending solar roof delivering a 'pumping charge' to the main hybrid battery which, in itself has doubled in capacity. On-the-road prices start at £29,195 after the UK Government’s plug-in car grant.
