Fastest Car: Mazda6
Output: 250 Horsepower / 310 Pound-Feet
Top Speed: 149 Miles Per Hour
0-60 Time: 6.7 Seconds (est.)
The Miata may be the sportiest Mazda, and can hit 60 in just 5.7 seconds, but the 6 sedan with its relatively new turbocharged 2.5-liter engine is technically the fastest car the brand sells. With 250 horsepower and 310 pound-feet, the four-door can sprint to 60 miles per hour in an estimated 6.7 seconds and on to a top speed of 149 mph. But the Mazda6 is no sports sedan, as we learned, and it starts at a relatively reasonable $29,800 with the optional turbo engine.
