The vehicle was powered by Maybach 'HL42TUKRM' petrol powerplant producing 100 HP which could drive the vehicle on roads at up to 38 mph with a range of about 200 miles before refuelling. Its cross country performance was good providing a max speed of about 19 mph and a range of about 100 miles.
It was armed with 1 light machine gun , a 7.92mm MG 34. Its main armament consisted of a 2.0cm Kwk 38 L/55 which could penetrate 6 mm of flat plate at 800 metres

Hit probability is based on a static 2 x 2.4 metre panel at 0 degrees(vertical) at the range specified.
The data that has been used to create these records has come from Wikipedia, The Lone Sentry, The Bundes Archive
and numerous books and websites that have provided the detailed information that has not been available anywhere else. The
information we use to calculate the penetration tables, flight times and the hit probability comes from the Gun Calibre,
the Shell Mass(Kg) and the muzzle velocity, plus range reductions to allow for gravity and wind resistance. This calculation
originally came from a pre-war Krupp calculation which has been modified, and seems to fit the actual test results.
