Recommended Posts



We need the max loaded weight and max speed of these early vehicles. Any know anything about them? We seem to be stumped on finding such info.


Leyland 3 Ton RAF




Benz-Gaggenau Type 5




1912 Crossley T5 Y 1616




Mercedes Kettenwagen 22




Just post here if you find anything. We're trying not to guess. In ROF such parameters weren't entered.

Leyland 3 Ton RAF


capacity 3 tons, speed .... I am still looking for.



      With the technological development of the internal combustion engines, the name was changed to Leyland Motors in 1907. Leyland supplied its first military vehicles, in the form of the X3, during the same year. During the dark years of WWI, the company supplied almost 6,000 examples of the 3-ton 4x2 S4X4 and S5X4 truck that was generally described as the ‘RAF-type Leyland’.

I'm not sure if this will be of use but it is from War Office Subsidy Trials, from April 1914.






Edit: A Leyland is mentioned and it seems like the vehicles weighed up to 4 tons 10 cwt (gross) with a load of 3 tons and could reach a speed of about 16 mph.
