When it comes to ultra-rare vehicles, the Koenigsegg CCXR Trevita stands above the rest. The Swedish boutique manufacturer only built two of these things, and one of them happens to be owned by boxer Floyd “Money” Mayweather, who made headlines in August 2015 by announcing he paid $4.8M for the privilege. The company describes the hypercar as a “diamond on wheels.” It’s not just hyperbole, either; the CCXR Trevita’s specially designed and coated carbon fibre body actually sparkles a silvery white under sunlight. The company originally planned to produce three copies of this car, but the process for manufacturing the white carbon fibre proved to be so difficult that the decision was made to limit production to just two.
The Trevita, which is a Swedish abbreviation meaning “three whites,” features a double carbon rear wing and a 4.8-litre V8 under the hood, pumping out 1,018 horsepower and 796 lb.-ft. of torque. It can hit 100 km/h from a standstill in a scant 2.9 seconds and has a top speed of over 410 km/h. Impressive, indeed
