VIDEO: Shhh... It's the Mercedes-Benz SLS AMG E-CELL in Action

Here are two new videos of the Mercedes-Benz SLS AMG E-Cell, both shot in Norway, where the German firm presented the prototype model to the press. In the first clip you can see the all-electric 'Gullwing' E-Cell along with the new S63 AMG, which packs a new, twin-turbo, 5.5-liter V8, running up and down an airstrip at Kristiansund, while the second video shows the SLS AMG E-Cell on the 'Atlantic Road' on the west coast of Norway.

We remind you the bright-colored SLS AMG E-Cell is a prototype model fitted with four-electric motors located near the wheels that produce the equivalent of 526HP and a continuous 880 Nm / 649 lb-ft. The car is still in development, but according to sources, Mercedes could have it ready for a limited production run by 2013.
