The vehicle was powered by FIAT-SPA '15TB M42' petrol powerplant producing 192 HP which could drive the vehicle on roads at up to 20 mph with a range of about 143 miles before refuelling. Its cross country performance was good providing a max speed of about 11 mph and a range of about 57 miles. Its main armament consisted of an Cannone contracarro da 75/32 M37 which could penetrate 79 mm of flat plate at 800 metres Armour Details Turret Front n/a Side n/a Rear n/a Top n/a Superstructure Front 30mm @ 11° (31mm) Side 25mm @ 9° (25mm) Rear 25mm @ 0° (25mm) Top 15mm @ 90° (15mm) Hull Front 30mm @ 45° (42mm) Side 25mm @ 0° (25mm) Rear 25mm @ 9° (25mm) Top 15mm @ 90° (15mm) Armour (x)mm @ (y)° (Effective mm @ 0°) Effective Armour - Maximum 42 mm - Minimum 15 mm Weapon Details Cannone contracarro da 75/32 M37 Calibre 75mm   Ammunition Details Name/Id Calibre Weight MVelocity Explosive Content AP (AP Armor Piercing) 75mm 6.3Kg 600M/Sec Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.17 0.34 0.7 1.49 2.38 3.39 4.55 5.88 Penetration(mm@30°) 91 84 77 68 58 51 43 36 Penetration(mm@0°) 106 98 89 79 68 59 50 42 Hit Probability(%) 98 98 98 88 54 25 8 3

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.
