Nissan Bluebird advert from 1986

The Nissan Bluebird is a compact- to medium-sized car launched in 1957. The nameplate still exists today on the Nissan Pulsar-based Nissan Bluebird Sylphy in Japan, and on the U13-based Nissan Bluebird in mainland China.

The Bluebird’s traditional competitor was the Toyota Corona from almost the very beginning of the product line.

It is one of the longest-running nameplates from a Japanese automaker. It even spawned the S130 Fairlady Z/280ZX, which in turn spawned the Maxima (originally 910 Bluebird/S130 Fairlady Z based), the 160J/710/Violet/Auster/Stanza line, and the US-built Altima line.
T12/T72 series
Nissan Bluebird T12/T72 

The T12 and the later T72 Nissan Bluebird, is in fact a third generation Auster, rebadged and sold in Europe. However, its well known build quality and reliability and the influential role it had in what is now Europe’s most efficient car factory merits the T12/72 its Bluebird badge.

The T12 was introduced in Europe in 1985 as a replacement for the U11 Bluebird. From July 1986, the T12 was assembled from parts shipped in from Japan, at Washington, England. The saloon versions (four door) were available first and the hatchback (five door) became available in January 1987. Using the U11 platform, Bluebird Estates were also built at Washington.
Export and foreign-built model names
Export versions were sold variously as the Datsun 510, Datsun 180B (with 160B and 200B versions) and the Datsun Bluebird. The Nissan Bluebird nameplate began appearing around 1982 as the Datsun marque was phased out in favour of Nissan.

From 1981 to 1985, Australia followed the Japanese convention by calling its car the Bluebird, and had a unique, facelifted rear-wheel-drive version for 1984 and 1985. That car was replaced in 1986 by the Nissan Pintara. It would be replaced by the successive Bluebird, also called Pintara, until 1992; then the range was brought in line with the Japanese model, for the U13 series from 1993 to 1997.

In the United States, the Bluebird was eventually sold as the Nissan Stanza. In 1992, the Stanza became the Nissan Altima. Currently, the Bluebird is not sold in North America; in 1998, the Altima was completely redesigned, becoming a model unique to the North American market.

The Bluebird sold in Europe between 1986 and 1990 was in fact a rebadged Nissan Auster—this was replaced by the Primera in Nissan’s European line-up in 1990.

A six-cylinder version called the Maxima was released in the 1980s and became a separate model.
