In the 2012 Mazda6 sedan, you'll find a family 4-door that melds the best attributes of a
luxury car with the spirit of a sport coupe to...
... create a very un-family-like sedan. The 2.5-liter engine that's standard on i trims (Sport, Touring and Grand Touring) is responsive with one or two people on board, but becomes sluggish with a full complement of passengers. The 2.5-liter's performance cannot match that of the newer, more powerful 4-cylinder engines, such as in the Kia Optima and Hyundai Sonata. If you value performance, the best choice for the 2012 Mazda6 remains the 3.7-liter V6. Coupled to a 6-speed automatic with a manual mode and Mazda's well-tuned suspension, the V6 has the power to motivate the Mazda6 while still returning decent, but not best-in-class, fuel economy. This, in the final appraisal, is a
mid-size sedan with sporting ambitions, although its size and engine/transmission lineup fall decidedly on the side of comfort over performance.
