While most of the cars we're hearing about in Frankfurt are of the fanciful supercar variety, Mercedes-Benz unveiled its most utilitarian of non-SUV models, the new E-Class wagon. The sedan and coupe versions of the E-Class were redesigned this year and are on sale now, but the new wagon won't make it stateside until later next year as a 2011 model. Because the new E-Class design — and Mercedes' design overall — has a lot more hard lines and creases than the competition, the wagon's wedge shape seems an easy transition for the designers. The profile is handsome and the front looks menacing; only the rear seems to be somewhat staid. It's a wagon — what are you expecting? Cargo volume is listed as 68 cubic feet, which would make it larger than the Audi A6 Avant (63.8 cubic feet) and the BMW 535i xDrive Sports Wagon (58.3 cubic feet).
