It's not necessarily because of the quality of the cars that the '6 does not sell... first there are the number of dealerships, of which there are many many more Ford stores. I've also spoken with Mazda staff about this, and people walking into the Mazda stores often end up with a 3 rather than a 6 because it is as uch as they need at a better price... Advertising wise, i think we see more skyactiv being pushed than the 6 as a model, so it remains an outsider in the mid-size sedan consideration process...
there are many reasons beyond the car that affect sales, which does not mean necessarily that a comparison is invalid (just because the brand you like didn't win). and don't forget, we rate the Fusion extremely high, ahead of Camry, Accord and others in the larger comparison we ran last winter, but even in this rematch, the 6 just nudges ahead for so many little reasons. this comparison and so many awards won't be enough to sway the sales charts, though. Even the Malibu outsells the Mazda6 - are you going to argue that the Malibu is a better car?
