BMW vehicles give least amount of CO2 per BHP

In a recent study by website cleangreencars.co.uk, cars from manufacturer BMW have been shown to give the most power per amount of CO2 released into the atmosphere.

By using the average values of CO2 released per kilometre, and the average brake horsepower (bhp) of a vehicle, the study looked at a number of different car manufacturers/models to ascertain the most efficiently powerful vehicles, and the general environmental performance of each automaker.

BMW came top of the chart with 0.74 grams of CO2 being released per kilometre per bhp produced. They bettered their teutonic competitors Audi and Mercedes to the top by a minimum of 0.07 grams of CO2. Mercedes claimed the second place, releasing 0.81 grams of CO2 per kilometre per bhp on average, with Audi an extremely near third, with 0.83 grams of CO2 per kilometre per bhp on average.

These figures can help to show the payoff that recent investment by the car manufacturers in their fuel efficiency systems has made. Standing out are their diesel engines, which now feature super-efficiency whilst maintaining their power output. This brings BMW, Mercedes and Audi well ahead of other car makers that specialise in smaller, supposedly more efficient vehicles.

A spokesman for cleangreencars.co.uk, on the back of these results, has said "Buyers need to check carefully which engine to go for, even within the same model range."
