4. Lotec Sirius
The Sirius is one of the most obscure European supercars the Lotec Company produced in the early 2000s. However, the prototype caused much attention when they first showed it in 2001. But ever since, the news about this crazy supercar has been scarce. Some say they only made two of them. Yet others think the Sirius never progressed beyond the prototype stage.
However, the Sirius is still one of the most powerful and interesting machines out there. The heart is a twin-turbo Mercedes-derived V12 engine that develops around 1,300 HP. With a five-speed manual transmission and weighing just 2,800 pounds, the Sirius is unbelievably fast. In fact, a 0 to 60 mph sprint takes less than 3.7 seconds and the top speed is an amazing 285 mph.
