Created for and by Lotec owner Kurt Lotterschmid. He said “it always a dream to make a completely myself” and that’s what he did with the Sirius. It was made for top speed and could reach a theoretical 400 kph, but the tires limit the amount to 380 kph.

Horsepower is variable dependent on turbo boost. On .85 bar boost the engine produces 1000HP @ 6300 & 1000 NM @ 3400. Both figures go up to 1300 with 1.2 bar boost. This massive amount of power is aided by the twin KKK turbochargers.

This concept car took 3 years to complete. Lotec says they can sell a road going version of this car which would take 1 year to complete. However, no road going versions have been created or sold.
