===Asal-Muasal===
Sama seperti [[Panzer III]] Jenderal [[Heinz Guderian]] mendesain juga Panzer IV ini. Dalam desain awal-nya, Panzer IV ini digunakan untuk Tank Pendukung Infanteri bukan untuk Tank vs Tank. Ideal-nya, setiap battalion tank dalam divisi panzer pasti memiliki kompani tank medium [[Panzer III]] dan satu kompi panzer berat Panzer VI. Pada 11 Januari 1934 [[Wehrmacht]] menulis spesifikasi "TankTraktor MediumPendukung", yangkarena akanpembuatan nantinyatank digunakandilarang setiapoleh battalion.Perjanjian Guna menggantikan tugas Panzer III, yang mempunyai selomgsong senjata hanya 37-millimeter, untuk itu Panzer IV akan di buat menjadi 75-millimeter (2Versailles.95 in)melewati dibeberapa senjata utamanya, jadi total beratnya sekitar 24 ton.tahun Namaberganti proyeknyanama adalahdengan Begleitwagen ("accompanyingKendaraan vehiclePendukung"),[8] ordisingkat BW, toyang disguiseproposalnya itsdiberikan actualkepada purpose,3 givenperusahaan thatbesar GermanyMAN, wasKrupp, stilldan theoreticallyRheinmetal boundnamun byhasil thedesain TreatyKrupp ofyang Versaillesditerima bandan ondi tanks.[9]Produksi MAN,massal Krupp,pada andawal Rheinmetall-Borsig1936 eachsetelah developedHitler prototypes,[7]mengumumkan withpenghapusan Krupp'sPerjanjian being selected for further developmentVersailles.[10]
The chassis had originally been designed with a six-wheeled interleaved suspension, but the German Army amended this to a torsion bar system. Permitting greater vertical deflection of the roadwheels, this was intended to improve performance and crew comfort both on- and off-road.[10][11] However, due to the urgent requirement for the new tank, neither proposal was adopted, and Krupp instead equipped it with a simple leaf spring double-bogie suspension.
The prototype required a crew of five men; the hull contained the engine bay to the rear, with the driver and radio operator, who doubled as the hull machine gunner, seated at the front-left and front-right, respectively. In the turret, the tank commander sat beneath his roof hatch, while the gunner was situated to the left of the gun breech and the loader to the right. The turret was offset 66.5 mm (2.62 in) to the left of the chassis center line, while the engine was moved 152.4 mm (6.00 in) to the right. This allowed the torque shaft to clear the rotary base junction, which provided electrical power to turn the turret, while connecting to the transmission box mounted in the hull between the driver and radio operator. Due to the asymmetric layout, the right side of the tank contained the bulk of its stowage volume, which was taken up by ready-use ammunition lockers.[10]
Accepted into service as the Versuchskraftfahrzeug 622 (Vs.Kfz. 622),[9] production began in 1936 at Fried. Krupp Grusonwerk AG factory at Magdeburg.[12]
