2010 Mercedes-Benz E-class Wagon

We've seen the latest E-class coupe and sedan, but Mercedes-Benz hasn't revealed the latest iteration of its E-class wagon. No matter -- thanks to our fast-acting West Coast editor and his Blackberry, we have some photos of the latest Benz wagon.

Engineers applied some light camouflage to this test car, but to no avail. There's no mistaking that Mercedes-Benz grille, although we're more interested in what lies underneath those padded hind quarters. It may be slightly obscured, but the disguise doesn't hide the rising rocker trim and the curvaceous rear fenders, both cues first shown on the Concept Fascination from the 2008 Paris motor show.

That show car, however, was designed more as a shooting brake than a familial mode of transport. We're not surprised that the Fascination's racy roofline has been nixed in favor of a more traditional profile, creating more room for kids, pets, and other cargo.

Likewise, the Concept Fascination's powertrain - a 2.2-liter turbo-diesel I-4 also used in the E250 Bluetec concept shown in New York - won't appear in production cars destined for North America. Mercedes-Benz plans on offering the next E-class wagon only as an E350, meaning a 268-hp, 3.5-liter V-6 will lurk underhood. While we wouldn't be surprised if a 4Matic model followed soon after, don't expect to see a diesel or AMG variant in the model mix.

Although we should see the final product in all its glory this fall (it's expected to debut at the 2009 Frankfurt motor show), the 2010 E350 wagon won't arrive stateside until the summer of 2010.
