with Nissan Motors. The appearance of the new Leone was influenced by the design efforts from Nissan, especially the long hood and short trunk appearance that Nissan was using at that time for their own products. The 1400 RX coupé was one of the first Japanese automobiles to be equipped with four-wheel disc brakes. A two-door hardtop coupé, with different bodywork than the two-door sedan or two-door coupé, was introduced in June 1973. The hardtop coupé received model names containing the letter F for "Formal" (FL, GF, GFT). A 4WD version with the sedan bodywork (model code A27) appeared in 1975. In the Japanese market, the sedan had to be equipped with the SEEC-T desmogged EA71 engine producing , whereas the station wagon was classified as a commercial vehicle and thus received a version of the same engine. The Leone was originally equipped with a 1.2- or a 1.4-litre flat-four, carbureted, OHV engine. The 1,100 cc engine from the earlier FF-1 G was carried over for the Leone 1100 van in the Japanese domestic market, but was only available in the first few years. In September 1975, as a response to tightening emissions regulations, the 1.2 was removed from the sedan lineup (although it continued to be available as a van-wagon version in the Japanese domestic market). To be able to offer as much power as the pre-smog 1.4 a bigger, 1.6-litre version was added for 1976. The Leone was available with a four-speed manual transmission, a five-speed manual transmission, and also a three-speed automatic transmission beginning in 1975. Some early models had duo-servo drum brakes at the front, however, later models were equipped with disc brakes. All models originally had rear drum brakes except the RX coupés. Unusually, the handbrake or emergency brake operated on the front wheels. In March 1977 an updated Leone range was released. All body panels were altered slightly and the overall look was 'smoother' and more contemporary in appearance. A completely new dashboard with altered interior were also part of the update. Despite these changes the overall effect was similar to the earlier version and it was mechanically identical, with the exception of the rear track which was widened by . The chassis codes were changed, with sedans now in the 30 series and estates in the 60 series. The little 1.2 continued to be available in the lowliest standard van model, with .
