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 km/h, but the tires limit the amount to 380 km/h.

Horsepower is variable dependent on turbo boost. On 0.85 bar boost the engine produces 1000 hp at 6300 rpm and 1000 Nm torque at 3400 rpm. 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.
