Isuzu TX40 Truck

In the mid-1920s, the Japanese government was promoting the manufacture of domestically-produced vehicles. Isuzu and Kawasaki worked together to design the TX40, a 2-ton truck made solely from Japanese parts. First produced in 1933, the two-door truck was made from a wooden frame with steel sheets. The flat bed could be covered with a canvas top. In military service, it was known as the Type 97.

The truck has room for one driver and two passengers. The Type 97 burns 2.2 gallons of gasoline per hour at routine usage. A full tank of petrol costs $3.36.

Design Notes:

Design loaded weight (without cargo) was 6,186 lbs.; this was within 0.004% of the historical empty weight. Historical loaded weight was arrived by adding cargo capacity (2 tons) to historical empty weight (2,800 kg). No historical top speed could be found.



The Type 97 was also produced as a fuel tanker. Given a 2-ton capacity, the truck could carry 590 gallons of gasoline in a light fuel tank mounted to the rear bed.

The TX35 was a 1.5-ton version designed for civilian rural use.
