Mazda Xedos was a range of executive cars launched by Japanese manufacturer Mazda in 1992.

The original model was the Mazda Xedos 6, which was similar in size to the BMW 3 Series. The Xedos 6 was known as the Eunos 500 in Japan. This vehicle was not sold in the USA.

By 1994, there was a larger model called the Mazda Xedos 9, which was of a similar size to the BMW 5 Series. The Xedos 9 was known as the Eunos 800 in Japan, and the Mazda Millenia in the USA.

Unfortunately for Mazda, neither versions of the Xedos were popular, and a facelift in 1998 did little to improve matters, and production ceased in 2000.
