Part of an article i copied from Drivetribe about the Bugatti ChironIt's big, heavy, has a W16 engine with four turbos, and can do a walloping 1,500 HP. We knew this wasn't going to end well as far as the EPA rating was concerned, right? It's not like you're buying the Chiron for its excellent mileage; in fact, it's quite the opposite. You might as well be in a contest to see which car can get the lowest mileage.
According to the Environmental Protection Agency, the Bugatti Chiron returns, wait for it, 9 MPG in the city and 14 MPG on the highway for a combined rating of just 11 MPG.
Using this combined figure, the EPA estimates that the Chiron's fuel tank is good for only
100 miles at best on the 9.1-gallon fuel tank. That assuming you hypermile the crap out of this car, and who wants to do that? Not a Chiron owner, that's for sure.
