Suzuki Alto is a kei car built by Suzuki. Its selling points have long included a low price and good fuel economy. The Suzuki Alto was first introduced in 1979 and has been built in many countries worldwide. The Alto badge has often been used on different cars in Japan and in export markets, where it is considered a city car. The eighth generation Alto was introduced in December 2014 in Japan, and has a more retro style. The new Alto was designed to have a very low fuel consumption, and is 60 kg lighter than the outgoing model. This was achieved using "Suzuki Green Technology" for the body and the engine, and resulted in the car having a claimed fuel consumption of 37 km/L. The new Alto is available with either a naturally-aspirated 658 cc inline-three engine, or a turbocharged version of the same power unit. It is available with either a 5-speed manual transmission, 5-speed semi-automatic transmission or a CVT automatic transmission. A Turbo RS variant started production in March 2015 which was followed by a performance-tuned Works edition by the end of the year.
