Mazda's midsize sedan enters a crowded market, and doesn't do much to distinguish itself. Beyond a couple of cool features, the Mazda6 generally stays behind the tech curve. Navigation is only available at the highest trim level, and real iPod integration isn't available at all. There's a little bit of Zoom in the tuning, but not the full Zoom Zoom promised by Mazda. The company is going to have to try harder to beat the likes of Nissan, Honda, and Toyota.
