CO2 emission numbers for cars from companies like Ferrari and Aston Martin are, to a Prius or clean diesel fan, pretty much a joke. Bentleys, for example, average over 400 grams of CO2 per kilometer. There are even some luxury vehicles that can put the supercars to shame, like the Mercedes-Benz S 500 Hybrid – with just 74 grams per km – shows. Still, if you start out ridiculously dirty, there’s a lot of room to clean up. This cleaning process is what JATO recently measured in a study of supercar company CO2 emission reductions. The average improvements are pretty big.
Ferrari came out on top by dropping 40.4 g/km, followed by Lamborghini with 39.1 g/km. When ranked by percentage difference, Alpina took top honors with 14.1 percent, with Porsche’s 10.6 percent improvement good enough for second place. Maserati decided to ignore the issue and actually increased average emissions by 20.9 g/km. We’re clear eyed enough to realize that the small volume and limited miles driven in these supercars means that, overall, their tailpipes don’t have much of an impact on the environment, but it’s good to see improvements being made anyway. Well, except for those Maserati’s. There’s a table with all the numbers after the jump.
