Mazda3 concept car SEMA

Mazda6 skyactiv-d concept car SEMAWhile the cars to look forward to at this year's SEMA show in Las Vegas are starting to stack up pretty high – Ford alone is bringing 57 vehicles – we hadn't gotten word about what Mazda was up to before now. A shadowy digital figure has reached out to the Autoblog staff, providing us with four tantalizing images of SEMA showcar renderings, though without any substantive information to go with them.

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.
