Price: $12.5 Million

With a price tag of $12.5 million and a selling price of $18.7 million after taxes, the one-off Bugatti La Voiture Noire is officially most expensive new car ever. And understandably. A modern interpretation of Jean Bugatti's personal Type 57 SC Atlantic, the La Voiture Noire uses the same quad-turbo 8.0-liter W16 engine as the Chiron, producing 1,479 horsepower (1,102 kilowatts) and 1,600 Newton-meters (1,180 pound-feet) of torque. It has six – that's right, six exhaust tips, radical new wheels, an aggressive, bespoke fascia, and a gigantic light-up badge out back that spells out the name of the brand. Of course, this one-of-one Bugatti already has a home.
