Bugatti Veyron Super Sport
Hennessey Venom GT
260 mph, 0-60 in 2.5 seconds, has a 6.2-liter LS9 Turbocharged V8 Twin Turbo V8 Engine producing 1200 hp, has a price tag of $950,000. The Venom GT has yet to be tested and proven, but could possibly hit a top speed of 275 mph. This might just be the Veyron Super Sport's closest competitor!
Koenigsegg Agera R
260 mph, 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 you're 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 Bugatti's arch enemy for the next 5 years.
SSC Ultimate Aero
257 mph, 0-60 in 2.7 secs. Twin-Turbo V8 Engine with 1183 hp, base price is $654,400. Tested in March 2007 by Guinness World Records, The SSC Ultimate Aero was the fastest car in the world from March 2007 to July 2010. On March 2011, the Koenigsegg Agera R also surpassed it, forcing this American made car to the #3 spot. Shelby SuperCars will continue their quest to reclaim the fastest car title, and their new SSC Tuatura might do the job (we'll just have to wait).
Saleen S7 Twin-Turbo
248 mph, 0-60 in 2.8 secs. Twin Turbo All Aluminum V8 Engine with 750 hp, base price is $555,000. Smooth and bad-ass. It will make you want to show it off non-stop.
Koenigsegg CCX
245 mph, 0-60 in 3.2 secs. 90 Degree V8 Engine 806 hp, base price is $545,568. Made in Sweden, it is the older brother of the Agera R, only losing to 4 other supercars in the world.
240 mph, 0-60 in 3.2 secs. BMW S70/2 60 Degree V12 Engine with 627 hp, base price is $970,000. The fastest car in the 20th century with doors that looks like bat wings. Maybe Batman needs to order one and paint it black
