From launch, the fleet is available from Heathrow and Stansted airports and at locations in central London, but the Yaris Hybrid will eventually be offered across a region spanning from Gatwick to Luton Airport.

Jane Goodwin, Avis UK fleet procurement manager, said: “Yaris scores highly in many respects against our requirements for an inner city hire car; it is easy to drive and reliable. The ultra-low emissions secured by its hybrid system make it a unique proposition in its class in achieving exemption from the London congestion charge.

Stuart Ferma, Toyota national fleet sales manager, added: “We’re confident that the special qualities of Yaris Hybrid – unmatched by any other vehicle in its class – will make it a popular choice with Avis’s customers and prove ideal for London driving.”
