The Nissan Sunny is a midsize sedan 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 a rebadged version of the Nissan Latio.
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.
