( http://www.TFLcar.com ) Is this the new and upcoming Mercedes-Benz S-class scheduled to be launched in the 2013 calendar year? The 2014 S-class will come with a variety of engine choices including six-, eight- and twelve-cylinder powerplants plus a diesel and hybrid version. This car looks to be a test mule that's high altitude testing in the Colorado Mountains. Early reports suggest that the finished car will look very different from the current model. The new car will be available in both rear and all-wheel drive models so that it can compete head to head with cars like the Lexus LS and of course the new Audi A8.Check out the video as we go prototype hunting for more spy photos of the 2014 Mercedes-Benz S-Class.
