seat. Front suspension comprised coils struts, with leaf springs at the back. The steering was of the recirculating ball type, and four-wheel drums were used. On introduction, the Alto received the T5B two-stroke (SS30) three-cylinder engine, producing at 5500 rpm. The Alto was a "micro sensation" when introduced, largely due to its rock bottom price of ¥470,000 (circa $1,900 in 1979, at a time when the cheapest Ford Pinto cost $4,999 in the US). This low price was made possible by a number of Japanese special concessions for commercial vehicles: most notably, the engine was subject to less stringent emissions rules and did not require expensive twin catalysts. Two fewer doors provided another saving, as did the exemption from commodity tax. The Alto's success changed the kei-car market, and other producers such as Subaru (with the "Family Rex") quickly followed suit with cut-price "commercial" vehicles that were really intended for private use. Suzuki was unable to keep up with demand the first few years, particularly in the home market. The Alto helped Suzuki move into seventh place in Japanese production for cars and trucks. In the last full year of production for this generation, it was still by far the best selling Kei car, with the Alto outselling the Fronte at a rate of about five to two. In May 1980, a fully automatic two-speed option was added to the Alto SS30. In January 1981, the F5A four-stroke from the Fronte was also made available for the Alto; although it only had a single-barrel carburettor, it too put out but at 6,000 rpm. Torque was considerably lower, however, down from . 1981 was also when it became available in the United Kingdom, as Suzuki began selling cars there that year. In export markets, the Alto name was used for the passenger car versions (chassis codes with trailing letter "S") as well as on commercials (ending in "V"), while the van was marketed as the "Suzuki Hatch" in Australia. The four-doors were not proper hatchbacks, only featuring an opening rear window. Export cars were also available with twelve-inch wheels, unlike the domestic versions which only used ten-inch units until the introduction of the 4WD version in October 1983. The 4WD "Snow Liner" thus gained an extra of ground clearance. Most export Altos were passenger car versions (which used the "Fronte" badge in the Japanese domestic markets), and usually received the F8B
