Panzer II Ausf. G from 1941 (manufactured until February 1942), also referred to as a VK9.01 (9 ton, 1st project), or Pz.Kpfw. II neuer Art, was an attempt to re-work and improve the Panzer II series in order to prolong their lifespan. It uses a different type of suspension with 5 overlapping roadwheels (in German "Schachtelaufwerk") and eventually led (over the Ausf. J) to the development of the Leopard. Several prototypes were built and subsequently around 12 vehicles were completed. Some sources claim they never saw combat, while other sources (H. Doyle) claim at least one was transferred to the eastern front and apparently used (as it was covered by a camouflage):
Panzer II Ausf. G was uparmored when compared to its predecessors and its frontal armor was cca 30mm thick (15mm on the sides). However, when it comes to armament and engine, different sources say different things (even though the performance is roughly equal): it was propelled by a 150hp engine (Maybach HL 45, or Maybach HL66) and armed with a 7,92mm anti-tank rifle, described in the Panzer I Ausf. C part. One development version was also armed with a stabilized 20mm KwK 38 autocannon.
Wiki states that its turrets were later used for fortification.
