We don't have any idea what is under the hood or behind the wheels of this foursome of two Mazda6s and two Mazda3s (hatch and sedan), but we can say that we like the way the company's lauded styling for all models is wearing the amped up wheels and paint schemes.
The Mazda3 hatchback seen here seems to be making overt overtures to the world of motorsport, with a lowered front splitter, super low-profile tires on massive wheels, and a number 3 writ large on the bodyside. The Mazda3 sedan gets a similar treatment without the numeration.
Mazda clearly isn't done telling the performance story for its impending Mazda6 Skyactiv-D diesel, either. The gray over black sedan is wearing a "CS6 Diesel" marking on its door, and could perhaps be a toned down version of the company's Skyactiv-D racecar. Look for more information about the SEMA cars on the Mazda stand, when we have it.
