1. SCC Ultimate Aero TT

They designed the Ultimate Aero to be the fastest, most powerful supercar on the market with engineering to represent a perfect blend of racing technology and streetcar design. The first Ultimate Aero models used a 6.2-liter Corvette racing engine with almost 800 HP that propelled this beast to 238 mph.

But they presented a real treat in 2009 with the release of the Ultimate Aero TT. It featured a turbocharged Corvette mill delivering 1,200 HP and an improved suspension, chassis, and aerodynamics. Soon, the Aero TT broke the production car speed record by achieving 256 mph, making it the fastest car in the world. With a price of close to $300,000, they only built 24 Aeros between 2006 and 2009.
