TheCarConnection.com's spies caught the redesigned Mazda 6 running on a secluded side street, within spitting distance of Ford's Detroit engineering operations. This is the most complete, most revealing Mazda 6 prototype spotted to date. This new Mazda 6 appears larger than the current model, confirming earlier sightings of cobbled-up test mules which hinted at added length and width for the second-generation model.
