With almost two weeks to go until its on sale date, the new generation Toyota Prius has already scooped its first award, winning the title of WhatGreenCar Car of the Year 2009.

On sale from 1 August 2009, the new Toyota Prius was chosen from a short-list of 10 green car finalists which were test-driven at Imperial College, London, by six of the UK's leading green transport and environmental experts. The judging was completely independent and showcased the most innovative green cars available to drive in the UK during 2009.

The 10 cars up for contention for the 2009 Award included: the Citroen C1 ev'ie electric, Mitsubishi i-MiEV electric, Toyota iQ, Ford Fiesta ECOnetic, third-generation Toyota Prius hybrid, Volvo S40/V50 DRIVe start-stop, Honda Insight, VW Passat BlueMotion 2, BMW 318d saloon, and the Citroen C3 Picasso compact-MPV.

Dr Ben Lane, Managing Editor of WhatGreenCar said: "While this year's judges were rightly impressed by the range of green car technologies employed by the 10 car short-list, they were unanimous in their acclaim for the new Prius. In addition to the new model's best-in-class cradle-to-grave environmental credentials, the panel particularly commented on the way the car seamlessly integrates green features as part of its design. If Apple made a car, it would probably be the third generation Prius."

With a lighter and more compact powertrain, the latest Prius is greener than ever with a best-in-class WhatGreenCar environmental rating, official combined fuel economy of 72.4 mpg and CO2 emissions of only 89 g/km – a 14 per cent  improvement over the highly successful current model, itself the winner of many awards since its UK launch in 2004.

Miguel Fonseca, Managing Director of Toyota GB PLC said: "It is a great honour to receive this award for the next Prius, particularly as the judges recognise the car's low, whole life environmental impact. From materials procurement through production, to in use fuel saving and even end of life recyclability, Prius sets the benchmark for all other cars to match."
