The first LD1 diesel truck was completed in November 1939. But it was the test drive shortly after that really got people talking. The majority of Japan’s roads at the time were unpaved and the country was full of narrow roads and bridges that were barely wide enough to fit a horse and cart. The course selected for the test drive was riddled with steep slopes and curves traversing perilous mountain passes. With the entire journey clocking in at a distance of 3,000km, or 1.5 times the length of the Japanese archipelago, it marked an endurance test the likes of which the nation had never seen. Some people were of the opinion that the test could easily be conducted in urban areas instead of going to such extremes. President Adachi had other ideas.
“What we want is a truck that can handle any road, no questions asked. If the truck doesn’t clear this test, we can’t expect our customers to feel confident in it. I know everyone has put a lot of hard work into this first model, but it’s crucial that we test the truck out in trying conditions, even if that means it gets wrecked.”
