Ovals are out on the 2010 Mercedes-Benz E-Class

EDMUNDS | Ed Hellwig, Senior Editor

When we first spotted prototypes of the 2010 Mercedes-Benz E-Class, it was pretty obvious the midsize sedan hasn't changed much. Even with heavy camouflage, its overall size and shape tell us that it barely differs from the current model. Unlike the smaller, extensively redesigned 2008 C-Class, the next-generation E-Class will continue on a more evolutionary track.

To see how the minor changes will affect the look of the 2010 E-Class, cues have been taken from the prototypes and combined with a little inside knowledge to create these photo illustrations of the E-Class sedan and wagon.

If there's anything about this luxury sedan that will get your attention, it will be the new design for the front end. It appears as though Mercedes-Benz is finished with oval headlights for awhile, as this E-Class will get a more squared-off front fascia. The headlights will adopt a shape that resembles that of the current S-Class, one that gives the E's nose a meaner, more angular look. Unlike the new C-Class with its choice of grille treatments depending on the trim level of the model, the E-Class is more likely to retain its traditional design with a three-pointed star perched atop the hood.

Apart from the obvious changes up front, the rest of the 2010 E-Class will remain classically conservative. No major changes to the belt line, no distinctive window shapes — nothing. None of this is necessarily a bad thing, as the E-Class is already one of the best-looking sedans and wagons around. Expect some revisions to the rear taillights and a few other minor detail upgrades, but nothing as dramatic as the front clip.

Look for the official debut of the 2010 Mercedes-Benz E-Class at the 2009 Frankfurt Auto Show.
