Official sketches of Mazda's custom concepts for next Thursday's 2013 SEMA aftermarket show in Las Vegas have found their way on the web, unfortunately, without additional information on the tunes.
The photos include a pair of 2014 Mazda6 sedans, in what we assume to be regular gasoline and diesel versions, plus two more 2014 Mazda3s in saloon and hatchback forms.
All four cars look like they're combining custom paint jobs with mild aerodynamic components and bigger wheels. We'll know if they're hiding any performance bits under their shells as soon as Mazda shares the details with us.
