Several years ago, Mercedes produced a prototype electric sports car called the SLS E-Cell that pretty much came and went. But, recently, at Nürburgring, a version of that car was spotted with all sorts of gadgets attached to it, presumably in the midst of testing. Perhaps the SLS E-Cell still lives?

Probably not! But Michael de Jong, who shot the video, has theories, though.

One possibility is that Mercedes is working on an electric version of the AMG GT and the company decided to use an old SLS AMG Electric Drive as a mule.

Mercedes’ high-performance division, AMG, has already committed to electrification with the AMG GT “coupaloon,” a four-door sports coupe with EQ Power+ boosting the 4.0-liter petrol V8 with hybrid electric power.

Could it also be preparing an all-electric successor to the electric SLS? Despite this sighting of this SLS E-Cell, no electric GT is on the cards.

Less than 100 SLS E-Cells were ever produced. I’m hoping that whatever car comes out of this test has a more sustained run.
