While most of us can only dream of owning the fastest car in the world, some will do whatever it takes to possess the most powerful speed. So, how fast are the fastest cars in the world?

Here are the 10 fastest street legal cars available on the market (production models, as opposed to concept or modified cars) measured by tested top speed (theoretical speeds do not count).

Worlds Fastest Cars:

#2 is a tie at 260 mph!

2. Koenigsegg Agera R: 260 mph (418 km/h), 0-60 in 2.9 secs. 5.0-liter V8 Engine with twin turbo’s, housing 1099 hp. Base price is $1,600,000. If youre into snow sports, the Agera R can be fitted with a Ski Box as well as winter tires, not that I would take one on a ski trip or anything like that. While the Agera R has a massive theoretical top speed, the current tested top speed is 260 mph. Expect this snow car to be the Bugattis arch enemy for the next 5 years.
