Just when you thought you couldn't see any more of the new 2010 Mercedes-Benz E-Class prior to its upcoming debut at the Geneva Motor Show, a healthy portion of the model's brochure has made its way onto the Web, revealing completely both the model's exterior and interior styling as well as key technical specifications. This, of course, comes after a prior series of leaked official photos, meaning Mercedes' viral marketing team has either been working overtime or the new E-Class is one of the worst kept secrets in automotive history. Either way, the European market now knows exactly what to expect from the model, starting with the fact that there will be by our count a total of ten engine variants (not including an AMG model). There's three CGI BlueEFFICIENCY variants the E 200 CGI BlueEFFICIENCY, the E 250 CGI BlueEFFICIENCY and the E 350 CGI BlueEFFICIENCY and there's four CDI BlueEFFICIENCY variants the E 200 CDI BlueEFFICIENCY, the E 220 CDI BlueEFFICIENCY, the E 250 CDI BlueEFFICIENCY and the E 350 CDI BlueEFFICIENCY. Rounding out the lot, an E350 BlueTEC, a traditional E 350 4MATIC, and the stalwart E 500 will all be available as well.
