Rather than starting with a concept, Mercedes is blasting straight into the market with the production E-Class coupe which is set make its debut alongside the redesigned E-Class sedan. After its North American debut at the New York auto show in April, it will go on sale in the U.S. in June of this year.
Not a great deal of technical information on the new E-Class coupe or sedan has been made public yet, but one number Benz is making a big deal of when it comes to the coupe is 0.24, its coefficient of drag number that Stuttgart says makes it the most aerodynamically efficient series production vehicle in the world. There are significant styling differences inside and out between the two cars. This is most likely due to the fact that the coupe is not only a variation on the E-Class, but a replacement for the CLK-Class, which is being discontinued.
Starting in the front, the E-Class coupe will stand out with its own grille, featuring fewer, beefier horizontal bars. Gone is the tri-star Mercedes-Benz hood ornament, replaced with a massive tri-star logo in the center of the grille. Down below, the radiator opening in the lower fascia has been slightly revised and is narrower and helps the front end look a bit more aggressive.
