It was commonly called a Hanomag. The vehicle was powered by Maybach 'HL-42' petrol powerplant producing 100 HP which could drive the vehicle on roads at up to 33 mph with a range of about 188 miles before refuelling. Its cross country performance was good providing a max speed of about 16 mph and a range of about 94 miles. It was armed with 1 light machine gun. Its main armament consisted of a 3.7cm PaK 35/36 L/45 which could penetrate 38 mm of flat plate at 400 metres The vehicles could carry 10 panzer grenadiers in a small arms and shrapnel protected space. The model D superceeded the A,B and C models by simplifying the vehicle to speed up production.

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.
