Koenigsegg CCXR Trevita ($4.8 million; 2 made in total) (5/10)

List item

Koenigsegg CCXR Trevita is the most expensive car in the world that can legally be driven on public roads. It is powered by a 4.8-liter double V8, with 1,004 hp and an estimated top speed of 254 mph.

But why does it cost this much? Koenigsegg created a white carbon fiber, the Koenigsegg Proprietary Diamond Weave, which is diamond-dust-coated carbon fiber. According to the company, the manufacturing process is extremely difficult and time-consuming, which is why only two of these cars will be manufactured.
