The Nissan Sunny, originally the Datsun Sunny, is a small car built by the Japanese automaker Nissan from 1966 to 2006. In the early 1980s, the brand changed from Datsun to Nissan in line with other models by the company. Although production of the Sunny in Japan ended in 2006, the name remains in use in the Chinese market for an unrelated vehicle.
In North America, the later models were known as the Nissan Sentra; in Mexico, the Sunny is known as the Nissan Tsuru, which is Japanese for the bird species "crane". The latest versions of the Sunny were larger than the early models, and may be considered compact cars. Earlier versions (through at least the B11 series) were subcompact cars. All Sunnys through the 1982 model year (except as noted below) used Nissan A engine motors. It was designed to compete with the Toyota Corolla.
Confusingly, the "Sunny" name has been used on other Nissan models, notably various export versions of the Nissan Pulsar model line. The Sunny has been imported and later manufactured worldwide under numerous names, and body styles, in economical, luxury and performance packages. Some configurations appear to be unique based on bodystyle appearances, but sharing a common platform. The Sunny was sold in Japan at a dedicated dealership sales channel called Nissan Satio Store, and rebadged versions later appeared at the other Japanese networks.
