Mazda6

The Mazda6 or Mazda 6 (known as the Mazda Atenza in Japan) is powered by one of two engines -- a 2.5-liter four-cylinder generating 170 horsepower and 167 pound-feet of torque or a 3.7-liter V6 that cranks out 272 hp and 269 lb-ft. The four is paired with either a six-speed manual transmission or a five-speed automatic, while the V6 is only available with a six-speed automatic.

The 6 is available in seven trim levels: i SV, i Sport, i Touring, i Touring Plus, i Grand Touring, s Touring Plus and s Grand Touring. Models with the "i" prefix come with the four-cylinder engine, while models with the "s" prefix come with the V6. Base models are respectably equipped, while higher trim levels come with such niceties as alloy wheels, xenon headlights, Bluetooth connectivity, dual-zone automatic climate control and an audible blind-spot monitoring system. Major options include a sunroof, an in-dash six-CD changer, satellite radio and a navigation system.
