In November 1977 a new top model arrived, the Leone Grand Am-T, which adopted the federalized safety bumpers and had an interior "inspired by American tastes." The Leone entered Australia and New Zealand in 1973, with cars imported fully assembled from Japan. The 4WD Wagon entered the Australian market in 1975, and remained the only vehicle in its class until the early 1980s. Many versions - sedan, wagon and Brumby (BRAT) coupe utility, were also assembled from CKD kits, from 1978, in New Zealand by then-importer Motor Holdings' Waitara plant near New Plymouth. Local assembly ceased when the Legacy range replaced the Leone in 1993. North America The Leone was first introduced to the United States in 1972. In 1976 the EA63 engine was replaced with the 1.6 liter EA71 engine. The EA71 engine was originally installed in cars equipped with automatic transmission but eventually supplanted the EA63 across the entire range of vehicles in the US and Australia. Using Subaru's new SEEC-T technology meant that a catalytic converter was not necessary, lowering cost and enabling the use of leaded fuel. Power in 49-state (US) trim was at 5200 rpm (two horsepower less in California), although drivability and gas mileage suffered distinctly from the emissions equipment. The Wagon was also available with four-wheel drive, beginning with the 1977 model year. A print ad for the 1973 Subaru GL coupé referred to the engine as "quadrozontal" The large bumpers required in the United States sat on hydraulic units; these were not a part of the original design and thus intruded considerably into the luggage compartment. Late in 1977 saw the introduction of the Subaru BRAT as a 1978 model. This was a two-seater body with a pickup truck bed, with two seats welded into the bed to evade the so-called chicken tax on light commercial vehicles. It brought the U.S. lineup to eight models in three trim levels. Most were in the volume DL trim except a base two-door, and the GF hardtop and 4WD models which shared a higher specification. For 1979, a decontented DL 4WD wagon and Brat were added along with fancier GL four-door sedan and 2WD wagon models bringing the total to twelve, the original fully equipped 4WDs also getting the DL designation. The original Brat was updated for 1981 with a dual-range 4WD transmission and the 1.8-litre EA81 engine. This was sold alongside the second generation
