At some point everyone has probably heard the phrase "Tell me which side of the argument you are on and I will give you the statistics to prove you are right!" That is certainly true when applied to comments made by Ferrari CEO Amedeo Felisa at the Paris Motor Show this week. While speaking to reporters, Felisa claimed that Ferraris as a group produce fewer total emissions than Toyota Priuses. Now anyone who has ever seen a Ferrari fly by would surely have to question this claim, there is certainly some validity to it. But as usual Felisa comes by the statement by cherry picking certain useful facts and leaving everything else behind. The argument is based on the total number of vehicles times the miles driven times the emissions per mile. The keys are the first two data points. Toyota has at least two to three times as many Priuses in the past decade than the total number of cars to come from Maranello in the Italian company's 61 year history. A large proportion of those Toyota hybrids are still on the road while many of the Ferraris are in Museums and other collections. Also Ferrari drivers who put more than just a few thousand miles on their cars annually are comparatively rare. So fewer cars and fewer miles means greener right? Well technically yes, but as usual the devil is in the details. In the grand scheme of things, the high cost of a Ferrari means the brand's overall environmental impact is fairly negligible compared to mainstream cars. It's probably all right to exempt low volume makers like Ferrari from some fuel efficiency standards. Still, making such an argument in general does come off looking rather silly.
