The Mazda6 was designed as a replacement for the Mazda 626 in 2002. It is a four-door sedan that could also be ordered as a wagon or five-door "liftback."  The first-generation automobiles in the United States were equipped with a V6, with different engine options available in overseas markets. In 2006 the MazdaSpeed6 model variant was introduced as a "high-performance" package that featured AWD and a turbo four-cylinder engine. Updates to the model would come in 2007 (for the 2009 model year in the US) and the third generation in 2012. Mazda did perform mid-generation cosmetic and technology updates. The model would be phased out by 2021 in the US, but continued in production for other markets.
