In 1935 a Hungarian-born British engineer comissioned a Hungarian company to build a one-off oil tanker for the Anglo-Iranian Oil Company. The AP1 was the result
Nicholas Straussler (born Miklós Straussler) (1891-1966) was born in Hungary. Before the WW1 he went to England. During the War he worked as a consultant for a military company. In the 1920s he came up with numerous patents for amphibian, folding vehicles, which attracted the attention of the British military.
Beginning in 1933 Straussler contracted the Hungarian Weiss Manfréd company to build military prototypes based on his designs. The automobile department of WM, led by János Korbuly developed a small car in 1926-1927, which failed to sell so they welcomed this new opportunity.
The Anglo-Persian Oil Company comissioned Straussler in 1935 to develop an oil tanker to be used in Iran, where road conditions were poor and the oil pipe network was under-developed. Straussler worked with Korbuly and his team on the prototype, which was called AP1 (Anglo-Persian 1st prototype, while other sources claim Autrotruck Petrol 1)
The chassis was 7,5 meter long. Power came from a 6-litre V8 engine, capable of 200 hp. Due to the two big coolers at the front, some believe the truck had two engines, but that’s not the case. The first two axles were driven. The lack of power steering made life difficult for the driver. Steering a 7-ton truck was not easy.
Viktor Szmick drove the car to Iran, which then featured a simple pickup truck bed. A photo survived in his collection about the trip.
This group picture was taken in Iran, when the truck was completed. On the right side stands Viktor Szmick.
The fate of the prototype is unknown, but it proved to be not-so-useful.
