3. Lotec Sirius
Lotec Sirius is one of the most obscure European supercars and it was produced by Lotec Company in the early 2000s. The prototype caused much attention when it was first shown in 2001 but ever since the news about this crazy supercar was pretty scarce. Some say that only 2 examples were made and some say that Sirius never progressed beyond the prototype stage.
However, Sirius is still one of the most powerful and interesting machines out there. The heart is a twin-turbo Mercedes derived V12 engine which develops around 1300 HP. With a 5-speed manual transmission and just 2800 pounds of curb weight, the Sirius is unbelievably fast. The 0 to 60 mph sprint takes less than 3.7 seconds and the top speed is amazing 285 mph!
