The Mazda6 is available in sedan and hatchback body styles for 2008, but the wagon has been discontinued. Buyers get a choice of two engines: a 2.3-liter four-cylinder or a 3.0-liter V-6. One of two automatics or a manual transmission can be installed. Competitors include the Honda Accord and Toyota Camry.

Other changes for 2008 include a newly standard tire pressure monitoring system, a Bose stereo for Touring trim levels, and 17-inch alloy wheels on the i Sport edition. The high-performance Mazdaspeed6 is no longer offered.
