 Toyoda Model G1 Truck

The founder of Toyota Motor Corporation, Kiichiro Toyoda, managing director and chief engineer of Toyoda Automatic Loom Works, decided to enter the automobile business with the aim of producing passenger cars for the masses that were suited to the conditions of the Japanese market, and he began research on small engines in 1930. In 1934, he completed a prototype of the Type A engine, which was modeled on the 1933 Chevrolet engine.
The first Model A1 prototype passenger car was completed in May, 1935, but priority was given to developing a truck, which would be easier to manufacture. In November of that year, the Model G1 truck was announced. It was powered by a Type A engine mounted on a chassis that was developed based on Ford trucks. Thanks to the chassis, the price was established at 2900 yen, 200 yen less than the Ford truck, on the assumption that the truck would be mass-produced.
Both the design and the manufacture were as yet not fully mature, and the quality of steel materials in those days was also inconsistent, which led to a series of problems. More than 800 individual points were revised, and the quality improved rapidly, along with the design and the manufacture.
Only 379 units of the Model G1 were produced, and in September, 1936, the improved Model GA truck was announced and went into production simultaneously with the Model AA passenger car.
