Judges will test drive the ten final cars at technological innovation specialist, Imperial College London, and the winner will be announced WhatGreenCar Car of the Year 2010.
Electric and hybrid cars dominate the shortlist, but the new 99g/km Seat Leon 1.6 TDI Ecomotive is included, as it the Vauxhall Corsa 1.3 CDTi ecoFLEX.
Only two models without specific ‘eco’ branding or alternative powertrains were included in the list; the new Citroen DS3 with 1.6 HDi engine and the Kia Venga 1.4 CRDi.
The Citroen DS3 has one of the lowest CO2 emissions in the top ten with 99g/km while the Kia Venga emits 117g/km.
However, judges will not base the final decision on tailpipe emissions alone. Emissions in the manufacture of the vehicles and production of the fuel will be taken into account as well.
All of the vehicles, which are eligible because they are available as a production model to buy, will be tested by judges including the Environment Deputy Editor from The Guardian, green campaigners, automotive journalists and the Managing Editor of WhatGreenCar.
Despite not featuring a car in the top ten this year, the Ford’s Fiesta ECOnetic was highly commended in the 2009 award and was labelled the ‘greenest supermini in the UK’.
In 2008, the Ford Focus 1.6 TDCi ECOnetic was voted at Green Car of the Year in the awards thanks to the lowest emissions in its class and high fuel economy.
