Get used to the aesthetics of the Mazda CX-5 – you're going to be seeing a lot more of it. Yes, the automaker's new Kodo design language will be rapidly spreading across the entire lineup, and that's clearly evident in these spy shots of the next-generation Mazda6 wagon. Friendly as the Nagare styling may have been, we're happy that Mazdas won't be smiling at us anymore.Here, we can clearly see the automaker's new corporate face with prominent details like a larger, more upright grille with a strong character line that extends into the headlamp surrounds. Around back, there's a rakish rump design with taillamps that appear to have been pulled straight off of the larger CX-5 crossover.Under that shapely new skin, expect a full suite of Skyactiv technologies to be employed – everything from lightweight materials to more efficient powertrains. Expect Mazda's 2.2-liter Skyactiv-D diesel engine to be the breadwinner elsewhere in the world. Here in the U.S., it's unclear if we'll even get the wagon variant, let alone the diesel. Mazda has confirmed that the Skyactiv-D engine will be coming to the States at some point, though what vehicle it will reside in is still unknown.The Mazda6 wagon will reportedly debut at the Moscow Motor Show at the end of August with the sedan to show up sometime thereafter.
