Following its divorce from Ford, Mazda realized (for at least the third time) that they can't sell enough cars based on driving enjoyment alone. There simply aren't enough car buyers who care. So, they've added a second focus, on class-leading fuel economy, and they've developed an array of new "SKYACTIV" technologies to achieve it. The new 2013 CX-5 compact crossover is the first car to employ the full array. Does the CX-5 deliver on both foci, old and new?
