The 2009 MAZDA6 sedan has been redesigned for the new model year and is available in "s" Value, as well as "s" or "i" trims in Sport, Touring and Grand Touring models. With new powertrains, the "i" models feature a 2.5L four cylinder engine, while the "s" trims come equipped with a 3.7L V6. The new design features greater overall dimensions (the vehicle is 6.1 inches longer and 2.3 inches wider) and increased trunk space. Dynamic stability control is standard across the model line. Touring models feature an advanced keyless entry system which automatically unlocks the doors when the driver approaches and grips the door handle. The top-of-the-line Grand Touring comes with dual automatic climate control and Bluetooth wireless compatibility.
