The 2010 Koenigsegg CCXR Trevita is one of the fastest rides on the planet, reaching speeds of 254 miles per hour. And only two were ever made.
But what was just as impressive when one recently rolled onto the auction block in Monterey, Calif., was the fact that the 1,018-horsepower hypercar was once owned by boxing champ Floyd "Money" Mayweather.
The knockout whip sold to the highest bidder for a cool $2.6 million.
CNBC's "Secret Lives of the Super Rich" got a look at the race-ready ride for an upcoming episode.
When Koenigsegg decided to make the Trevita, the company developed a unique coated fiber solution that transformed the usually black carbon fibers the body is made from into "a sparkling, silvery white," which "shines like millions of diamonds when the sun hits the car," according to the Koenigsegg website.
The company was going to produce three of the light-colored model ("trevita" translates from Swedish to "three whites"), but they hit a roadblock.
"Due to the extreme complexity of turning this darker carbon into a silvery white, they elected to only build two and make the two that exist even more collectible," says Kirk Fiechter, curator of Ash Crest Collection, a privately held collection of cars, including a variety of limited-production exotic models.
The pair were painstakingly handcrafted in a fighter-jet hangar that Koenigsegg transformed into the company's headquarters.
Only one of the Trevita models is in the US. Until recently, it had its home in the garage of "Pretty Boy" Floyd himself, who secured a 50-fight undefeated streak when he won against UFC champion Conor McGregor this past August.
"He loves all the extreme cars," says Fiechter. "It's so fitting. It's the champ's car."
