The Mazda6, also known as the Mazda Atenza in China and Japan, is a large family car produced by the Japanese car manufacturer Mazda since 2002, now in its third generation. It replaced the long-serving Mazda 626 (sold in Japan as the Capella) which replaced the Mazda 616 (piston engined version of the RX-2) in 1977. The Mazda6 has sold over one million units worldwide since its introduction, hitting this sales milestone faster than all previous Mazdas, only for the Honda Fit to break it in later years.
