The Panzer I Ausf. F, was as different from the Ausf. C as it was from the Ausf. A and B.[28] Intended as an infantry support tank, the Panzer I Ausf. F had a maximum armor thickness of 80 millimeters (3.15 in) and weighed between 18 and 21 tonnes.[29] The Ausf. F was armed with two 7.92 mm MG-34s.[30] Thirty were produced in 1940, and a second order of 100 was later canceled. In order to compensate for the increased weight, a new 150 horsepower (110 kW) Maybach HL45 Otto engine was used, allowing a maximum road speed of 25 kilometers per hour (15.5 mph) and used five overlapping road wheels per side, dropping the Ausf. C's interleaved units.
The Tiger II was the successor to the Tiger I, combining the latter's thick armour with the armour sloping used on the Panther medium tank. Contemporaneous Allied soldiers often called it the King Tiger or Royal Tiger. It was the costliest German tank to produce at the time. The tank weighed almost 70 tonnes and was protected by 100 to 185 mm (3.9 to 7.3 in) of armour to the front. It was armed with the long barrelled (71 calibres) 8.8 cm KwK 43 anti-tank cannon. The chassis was also the basis for the Jagdtiger turretless Jagdpanzer anti-tank vehicle.

The Pz.BeobWg V Ausf.A, also known as the Panther IV artillery observation tank, was developed as a successor to the Panther IV. It was based on the A-type hull and equipped with a swivel turret and a dummy barrel. By the end of the war, about 40 vehicles had been completed, and some were said to have been deployed in combat.
