The guide, which highlights the best and the worst cars in terms of their impact on the environment, is published today online at www.eta.co.uk by the Environmental Transport Association (ETA), the breakdown service.
Second on the list was the Toyota Prius 1.5 Hybrid, which is the most efficient mass produced car on the market, with 66mpg and CO2 emissions making it the lowest of all cars at 104g/km.
The guide also highlight’s the worst offenders in terms of damage to the environment. Top of the list for highest emissions – again for the second year running is the Lamborghini Diablo. This is closely followed by the Bentley Arnage R and two Aston Martin models: the Vanquish V12 and the DB9.
