The United States Environmental Protection Agency has revealed its fuel economy ratings for Bugatti’s latest supercar, the Chiron: the 1,479-hp coupe is rated at 9 mpg in city driving, and 14 on the highway, for a combined figure of 11 miles of driving on every U.S. gallon of premium gasoline.

Converted into the metric L/100 measurement Canada uses, that works out to 26.1 in the city and 16.8 on the highway. That’s a lot of fuel, for sure, but consider the Chiron’s combined rating is actually one mile-per-gallon better than that of the outgoing Bugatti Veyron, a car with “just” 1,183 horsepower in its most potent form.

For some perspective, you could drive a convoy of five Toyota Priuses – Prii? – rated at 4.4 L/100 km highway for about the same cost as one Chiron, accounting for the Bugatti’s need for pricier premium fuel.

And that’s assuming you’re obeying North America’s restrictive speed limits. On Europe’s faster highways, Chiron drivers can expect to empty the car’s 100-litre fuel tank much more quickly than the car’s highway driving estimate would suggest. I mean, if you hypermile it and try to stretch its range, at best you’ll get just over 350 km.

Just in case anyone who can afford the Chiron’s $3,000,000 US price tag is concerned about how much it costs to operate the car, the folks at the EPA figured that out, too: They say filling the tank will run you $3,800 per year (based on 15,000 miles of driving) and cost $12,250 more to run over five years than the average new car.

Earlier this year, Popular Mechanics magazine got an up-close look at the Chiron, which has a 381 km/h top speed but can be driven to 420 km/h with the use of a special key. At that velocity, the car is covering more than 1.5 km every ten seconds. Apparently, the car is technically capable of breaking the 300-mph mark (483 km/h!), but no tire currently exists that can handle that kind of speed.

And though the Chiron is rated more efficient than the Veyron, Top Gear estimates that at its top speed, the newer car would drain its tank in _nine minutes_—three minutes quicker than the Veyron. That means that at 420 km/h, the Chiron could travel just 81 km before running out of fuel.
