The history of Suzuki four-wheel drive cars began in the latter half of the 1960s, when Suzuki bought a Steyr-Puch Haflinger to study with the intent of building a kei class off-road vehicle. A better opportunity presented itself in 1968, when Suzuki was able to buy bankrupt Japanese automaker Hope Motor Company, which had introduced a small off-road vehicle called the HopeStar ON360. The tiny Hope company had been unable to enter series production and only about 45 were manufactured. The first Suzuki-branded four-wheel drive, the LJ10 (Light Jeep 10), was introduced in 1970. The LJ10 had a 359-cc, air-cooled, two-stroke, in-line two-cylinder engine. The liquid-cooled LJ20 was introduced in 1972 with the cooling changed due to newly enacted emission regulations, and it gained 3 hp. In 1975, Suzuki complemented the LJ20 with the LJ50, which had a larger 539-cc, two-stroke, in-line three-cylinder engine and bigger differentials. This was originally targeted at the Australian market, but more exports soon followed.
