With only a few pieces of tape covering the front and rear headlights, the E-Class Cabrio looks production ready.

Our spy photographers have managed to catch Mercedes' 2010 E-Class Cabrio undergoing high performance testing on Germany's Nurburgring.

With only a few pieces of tape covering the front and rear headlights, the E-Class Cabrio looks production ready. Styling follows the standard E-Class Coupe, but as we have previously reported, the drop top features a unique windscreen-mounted wind blocker that deploys when the roof is lowered. While it doesn't look terribly attractive, it should reduce turbulence inside the cabin.

Under the hood, expect Mercedes' typical assortment of gasoline and diesel engines. Reports have indicated that Mercedes has killed off AMG versions of the E-Class Coupe and Cabrio, so the most powerful engine will likely be the 5.5-liter V8 with 285 kW (382 hp).

Look for the new E-Class Cabrio to be officially unveiled at the Frankfurt Motor Show.
