Rumor has it that Mercedes-Benz is planning a roadster version for the SLS AMG E-Cell electric supercar that debuted at the 2012 Detroit Auto Show.

Said an undisclosed Mercedes-Benz representative, “We will see how great the demand becomes. We currently have no idea how many people are actually interested.” Sounds like Mercedes-Benz will see how the fully-electric gullwing supercar sells first and then make a decision as to whether or not there will be a demand for a roadster version.

To recap, the SLS E-Cell uses four electric motors to generate a combined 526 horsepower and 649 pound feet of torque, achieving a 0-60 time of four seconds.
