The LJ50 engine gained a cylinder to meet new kei car regulations regarding maximum displacement. With a 6.0:1 compression ratio, at 5500 rpm and at 3500 rpm, was first introduced in September 1975 for export market Suzuki Jimnys, which were usually marketed simply as the "Suzuki LJ50". In export market Carrys it has a somewhat lower compression ratio of 5.9:1 and this version develops at 4500 rpm and at 3000 rpm. It first appeared for the home market in June 1976 as the Jimny 55, subsequent to the changing of Kei car rules while also addressing stricter emission standards. The straight-three engine remained a two-stroke; while power remained at 4500 rpm more low-end torque was on offer - at 3000 rpm. Both figures were obtained at considerably lower engine speeds.
