Clean Green Toyota
So who really leads the way when it comes to cleaner, greener motoring? According to an influential website Clean Green Cars, it's Toyota by a comfortable margin - and the site has done its maths with a unique 'Index of Efficiency'.
Clean Green Cars - an independent authority on the eco-friendly automotive market - has worked out the 'actual average' of C02 output based on each manufacturer's sales. It compared this with what the figure would be if the manufacturer's cars performed in line with the industry average for C02 emissions. It calls this figure the 'predicted average'. In this way we can see who's leading the way, or lagging behind, when it comes to lightening the load on the environment.
The site has high praise for Toyota, and not just because it tops the table with an impressively low actual average of 124.78g/km of C02. It also notes how the figure is nearly 15g per km lower than the predicted average. This, the site says, 'is a rare case of a company being best in both absolute and relative terms.'
Clean Green Cars points out that such strong performance is not just down to hybrid technology: 'The Optimal Drive system also means its petrol and diesels are better than average.'
Nissan, in contrast, has an actual C02 average of 146.02, which is 5.92g/km of C02 over the 140.10 average predicted by Clean Green Cars. Ford, meanwhile, has a 142.68 actual average, 1.16g/km above a predicted 141.52.
