“Buff my tank!” – Panzer I series

Hello and welcome to “Buff my tank!

The “Buff my tank!” articles are meant as an historical way to look at some tanks considered underpowered in game and ways to improve their combat abilities discussed by the original German engineers.
Beware that while being sometimes ironic in tone, the article treats about both costs and benefits of every choice and it most likely will never be listened by WG as suggestion.

Often forgotten and underestimated in the shadow of its mightier successors, the humble Panzer I was mainly meant to be a training tank but ended up being a pretty important part of the early Polish and French blitzkrieg campaigns.

During its service history several modifications and evolutions were developed and proposed, sometimes greatly changing the tank’s role far away from the puny vehicle that didn’t exactly shine during the Spanish civil war and versus later opponents.
For this article we will use “Panzers I and II and their variants by Spielberger, “Panzer Tracts 1-1” and “Panzer Tracts 1-2” by Jentz & Doyle


The staring projected armament of two MG13 clearly designated the tank to be used mainly against infantry and soft skinned vehicles as their penetration was too lackluster against most armored vehicles.

During the Spanish civil war the 20mm Breda auto-cannon was installed, giving it some punch against similar light tanks.
The VK 6.01(ausf C) upgrade brought the EW 141 MG that allowed better penetration, although using precious Tungsten.


A measly 13mm all-around protection was enough to protect against SMK, but anything heavier would pierce it easily. Bolt-on 15mm plates were often added, giving it decent protection against weaker auto-cannons and AT rifles.

Panzer I ausf C brought frontal armor to 30mm (at the price of bringing weight to 8 tons), although it was the VK 18.01 (ausf F) that in December 1939 brought a serious upgrade to 80mm frontal and 60mm side armor, though at the price of bringing the weight to 18-19 tons with evident effects on mobility (a top speed of 25 KM/H was planned):


The Krupp M 305 engine at 60HP was nothing to write home about although at 11 HP/ton it still allowed a maximum speed of 40KM/H for the ausf A on roads.
One of the very first proposed upgrades was the 80HP Krupp V-8 engines during design phase in 1932, while also of note is the 85HP air-cooled Krawa engine tested in 1934/35.

In 1935 the Maybach NL 38 was added, which at 100HP was a definite improvement in mobility.
In September 1939 the 150HP Maybach HL 45p was to be installed in the ausf C, giving the vehicle a top speed of 65km/h (18,75 HP/ton) although the drive train was rated for an extreme 81 KM/H.

An even more extreme upgrade was planned in 1942 for the VK 6.02, installing a 200HP Maybach HL 50 engine which would have given an amazing speed of 80 KM/H with a power to weight ratio of around 25 HP/ton.


Although a viable design in 1939, Panzer I was always quite under-gunned and modifications given to keep it in par with competition never brought it above decent.
WOT already shows most upgrades (aside from the Ausf F/ VK 18.01-02 which could be an interesting tier IV if used with limited match making).

All in all: No further buffs possible unless using a pretty much new design

      • I see. And ingame what weapon would it use? The one from Pz. I. C.? It would have some problems with it on tier IV and V.

        • Would have to be unhistorically buffed to EW 141 or 2 cm FlaK.

          The real thing only had two MG 34s. It was never intended to fight tanks or even other armoured vehicles.

            • Yeah, it wouldn’t be good as historical premium but it could work at tier III-IV similar to Panzer II J if upgradeable the same way as Panzer I C.

              200 HP engine would propel it semi-steadily at 25 km/h, making it the fat, though brother of Panzer I C.

  1. You forgot to mention why the Pz I in game even has the 2cm gun.

    The 2cm cannon (2cm cannon of the AA model) was planned for the Pz I but there were delays with implementing it so the plans were pushed back 2 years on the orders of the army even though a wooden mock up was fitted to a hull and tested for fitting and ease of movement with the 2cm gun. Circa ~1932.

    MG.13, 33 and the Rheinmetall E.M.G. (MG. 34) are all options.

    Pz Tract 1-1.

  2. PzI one of the shittiest low tier tanks in the game and they still nerfed it recently. Iirc they nerfed pretty hard turret traverse and made it even shittier. Turret traverse on low tiers means a lot because of the fast paced gameplay, BUT it was so OP that they had to nerf it. Sometimes WG seems like they have no idea what are they doing.

      • EDIT: I stand corrected. They did nerf the turret traverse (although they buffed the 2 cm gun).

        Then again, a lot of the lower tiers got their turret traverse nerfed.

        • Nah, they didn’t touched PzIc…i remember that it was PzI because i wrote back then that that nerf was stupid because the tank itself was already UP….don’t remember what they buffed on the 2cm gun, but the turret traverse nerf was pretty hard…
