year, the station wagon continued to be built until 1990. The six-cylinder Maxima also continued to be built (without the "Bluebird" portion of the name from May 1987) until October 1988, when an all-new Maxima appeared. Most of the wagons sold in Japan were to commercial vehicle specifications, but a plusher Wagon was also offered. The "Bluebird Wagon SSS Turbo Wingroad" had a 1.8-liter inline-four. It was the first car to receive the "Wingroad" name, in September 1987. The wagons/vans were built until May 1990, when they were replaced by the Nissan Avenir (Primera wagon in most export markets). The range was available with 1.6, 1.8 and 2.0 L petrol engines, with the 1.8-litre four available with an optional turbocharger. The VG20ET V6 was offered for the first time in Japan in 1984, in a model with an extended front end, called the Bluebird Maxima. This 2-litre V6 was available naturally aspirated or as an intercooled turbo. The U11 Maxima featured a larger 3.0 L VG30E. There were also naturally aspirated or turbocharged 2-litre diesels. Counterintuitively, the turbodiesel had better gas mileage in standardized test cycles, presumably due to it being less stressed – as long as one did not take full advantage of its better performance. Australia continued with the 910 series, which was facelifted in 1985. New Zealand marketing for the U11 proclaimed the vehicle as the 'Widetrack Bluebird', to differentiate it from its very similar-looking predecessor. Several Wiri-assembled models including a wagon were offered with 1.6 (base) or two-litre carburettor engines. The alloy head castings all had an unused location for a second spark plug per cylinder, as twin-plug, fuel-injected versions of the same engines were used in certain markets (US, Japan, Scandinavia) with stricter emission laws. In the United Kingdom, the following versions were offered: 1.8 DX (1984–86) 2.0 GL/GL estate/SGL (1984–86) 1.8 Turbo ZX (1984–86) The U11 was sold as the Yue Loong Bluebird 921 / 923 in Taiwan. T12/T72 series The T12 and the later T72 Nissan Bluebird, is a third-generation Auster, rebadged and sold in Europe. 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. U12 series Nissan replaced the boxy U11 in September 1987
