Mazda's US sales are down a little bit but the company's fuel economy is almost assuredly up. That's because its fuel-saving Skyactiv drivetrain technology is essentially taking over US vehicles sales. To the tune of about five out of every six vehicles sold, at least.
Mazda3 sales in the US were down about 15 percent last year to a total of 104,713 units. According to a report from Automotive News, though, the slowdown in sales has been due more to production constraints than demand.
