The Mitsubishi PX33 is a prototype passenger car built by Mitsubishi Heavy Industries, the company which would eventually sire Mitsubishi Motors. Commissioned for military use by the Japanese government in 1934, it was the first Japanese-built sedan to have full time four-wheel drive, a technology the company would return to fifty years later in pursuit of motorsport success. Four working prototypes were built, and a version was in development using Mitsubishi’s 6.7 litre, 70 PS (51 kW; 69 hp) 445AD powerplant, Japan’s first direct injection diesel engine.
