Motorists looking for the car that is top of the league in terms of its greenness may want to hold out for another year to sample the Volkswagen Polo Bluemotion.
The vehicle goes on sale in May 2010 and reaches new heights in terms of its fuel consumption and the carbon dioxide it generates, according to a reviewer.
Writing for Car Magazine, Phil McNamara states that by focusing on aerodynamics and adding a 1.2-litre diesel engine to the Polo, it can return 85.6 miles to the gallon, while only generating 87g/km of CO2.
Other features of the vehicle that enable it to become more eco-friendly are the inclusion of start-stop technology, causing the engine to be turned off when the car is stationary, and low rolling resistance tyres.
Meanwhile, Mr McNamara adds that the Bluemotion also shares the other strengths synonymous with a Polo, including a brilliant chassis and a fluid ride.
Many of the vehicles under the Volkswagen Polo umbrella are available in both three and five-door forms, while motorists also have the choice from a range of petrol and diesel engines.
