Car and Driver did the instrumented tests that resulted in the 7.2s time 0-60mph; however, they commented in that article that the reason the lateral acceleration was so mediocre was that the track was dusty and slippery. Perhaps their 0-60mph run was on the same slippery track, because they almost always get the quickest acceleration times, and MotorWeek just about the slowest, at least with manual transmissions.
And I agree with LH451: The 2.5L is ridiculously fast for what it's supposed to be. It's significantly faster than my slightly modified 2012 Focus was, and both are rated for the same fuel efficiency. I recently calculated averages for my last 2012 Focus Titanium hatchback with THP and my Mazda3. The Focus was 32.7mpg and the 2014 Mazda3 was 32.6mpg. It would probably have beaten the Focus if I could keep my finger off the Sport button and my hands off the paddle shifters.
