One of Floyd Mayweather’s most prized possessions, his Koenigsegg CCXR Trevita, is up for auction during the Monterey sale this August, 16 through 19, from Mecum Auctions.

As one of only two built and the only example completed to U.S. market specification, this 2010 Koenigsegg CCXR Trevita from the Ash Crest Collection is one of the most exclusive cars on Earth.

The five division world champion fought off several parties that were interested in purchasing the vehicle - and paid a whopping $4.8 million for the car. With only 1,947 miles on the odometer, the CCXR Trevita is fairly lightly used.

The collectible car is powered by a 4.8-litre V8 twin-supercharged DOHC aluminum engine that churns out 1018 hp and 1080 Nm of peak torque and is mated to a transversal paddle-shift automatic gearbox.

The car is completely made of Koenigsegg Proprietary Diamond Weave carbon fiber. The car can go from 0-100 km/h in 2.9 seconds and 0-200 km/h in 8.7 seconds.

Koenigsegg initially planned only three CCXR Trevitas for production, but because of the complexity of the Diamond Weave production process, that number was reduced to two, making this one of the rarest of Koenigsegg’s creations.

Both cars feature the shimmering Koenigsegg Diamond Weave bodywork, double carbon rear wing, carbon-ceramic brakes with ABS, Airbags, paddle shifters, Chrono Dial control cluster, infotainment system, tire-monitoring system and a hydraulic lifting system to protect their undercarriages.

The Trevita’s power-assisted carbon-ceramic disc brakes follow modern supercar convention, combining ventilated 1.34-inch wide, 14.9-inch diameter discs and 8-piston light alloy Brembo monoblock calipers up front with 1.26-inch wide, 14.25-inch diameter discs and light alloy AP Racing calipers at the rear.

Mayweather will return to the ring next month as well, fighting UFC champion Conor McGregor in a boxing match on August 26th at the T-Mobile Arena in Las Vegas.
