<\/p>\nSome wild vehicles showed up at the\u00a0Supercar Owners Circle weekend in Spain. One of the more eye-catching machines was a\u00a0Koenigsegg One:1 with an exposed carbon-fiber body. Crowds flocked to take photos of it.<\/p>\n
The One:1 was a variant of the Agera, and the name referred to the weight-to-horsepower ratio. The twin-turbo 5.0-liter V8 pumps out 1,360 metric horsepower (1,341 horsepower), and the car weighs 1,360 kilograms (2,998 pounds). The powertrain hooks up to a seven-speed dual-clutch gearbox. It can reach 249 miles per hour in about 20 seconds. The estimated top speed of 273 mph puts the vehicle among the fastest automobiles in the world.<\/p>\n

The One:1 features an aggressive body that can make 1,345 pounds of downforce at 160 miles per hour. It rides on carbon-fiber wheels that measure 19 inches in front and 20 inches at the rear. The brakes feature 15.63-inch rotors in front and 14.96-inch discs at the back.<\/p>\n
At low speeds, the\u00a0One:1’s engine note is particularly raspy. The sound transitions to a wail as the revs increase.<\/p>\n
Koenigsegg made just six customer examples of the One:1, plus a prototype. The extreme rarity means that seeing one is special and partially explains why the crowds are giving this machine so much attention.<\/p>\n
The\u00a0One:1 debuted at the\u00a0Geneva Motor Show in February 2014. It premiered in the United States at The Quail, A Motorsports Gathering, during Monterey Car Week in 2015.<\/p>\n
In 2019,\u00a0Koenigsegg was upset when Bonhams put a\u00a0One:1 up for auction with a sale estimate between\u00a0$1.8 million and $2.4 million. The company believed the auction house was undervaluing the hypercar. “For some reason, not understood by us, Bonhams are uninterested in giving a correct starting point or accurate estimate for the One:1, as they have shown complete lack of interest in trustworthy facts and figures presented to them,” the automaker wrote in a blog post at the time.<\/p>\n
