Commonly known as the "Iron Pig", the FJ55 was produced for model years 1967 to 1980 and was the first true station wagon in the Land Cruiser series. Although the FJ55 was classified as a commercial-use vehicle in Japan, it was positioned as a passenger vehicle in overseas markets where it was principally sold. The 4-door wagon was based on the 40 Series gasoline drivetrain (3-speed, F engine, 125 hp) and replaced the 4-door FJ45LV with a longer wheelbase. In 1975 it received a much needed upgrade to the Toyota 2F engine with better efficiency, power, and a 4-speed manual transmission.
