The Mazda 6 sport sedan replaces the Mazda 626 and the Mazda millenia in the Mazda USA model line. It replaces the Mazda 626 in Austrailia (thanks simonc). With the Mazda 6, the company wants to introduce the idea of "Emotion in Motion" where cars appear athletic and well-performing. Driver pleasure, occupant comfort, safety, solid craftmanship and packaging flexibility are priorities. Their aim is to be a cheaper version of the BMW 3-series.
This vehicle was designed as an entirely new car on a new platform with a new family of engines. A wagon and hatchback version should be coming to the US. The Mazda 6 is produced in Flat Rock, Michigan and went on sale in fall 2002. It's market competitors are the Honda Accord, Toyota Camry and the VW Passat.
