If the makers of the fast cars are large manufacturers, these regulations should be pretty easy to overcome. Consider Ferrari, which just released the fastest road car in the company’s history, the 599 GTO Ferrari is owned by Fiat SpA, which luckily is already selling fuel efficient vehicles in the US. But brands that don’t sell cars besides luxury autos in the US are scrambling for ways to meet this regulation, like developing smaller, more fuel efficient cars (both Aston Martin and Jaguar are trying that route). Tiny (fewer than 5,000 vehicles sold per year) manufacturers are hoping that the EPA makes special allowances for them since the government agency has said these companies will get their own rules. Larger car makers (50-400k cars) are allowed to have 25,000 cars per year exceed mileage targets without being penalized.
