Since the early nineties, big German car-makers DaimlerChrysler,
Group have had an informal agreement in place to limit the top speed of their cars to 250 km/h (155 mph). Of course, that electronically limited, artificial cap has done nothing to thwart the horsepower wars among these three companies. Every successive generation of their cars has gotten faster, particularly the
S /RS and
models. Of course, in order to make these prodigious power figures, more fuel and air have to be combined in the combustion chambers, and that means more carbon dioxide emissions.
Recently, a German environmental group Deutsche Umwelthilfe filed suit against DCX, demanding that it publish the fuel consumption figures in their ads for these high power models, as a way of indicating their carbon emissions. Last week a Stuttgart court agreed, and according to a DCX spokesman "We will respect the court's ruling." No word was offered as to why DCX was singled out among the German automakers, but for now it will have to
its fuel mileage along with its miles per hour.
