The SLS AMG from Mercedes-Benz is one of the most popular supercars available today. With its gullwing doors, exotic design and brutal V8 power, the SLS AMG is perhaps the most sought-after AMG model in recent years. What automotive enthusiasts may not know is that Mercedes-AMG GmbH has developed an electric version of this supercar called the SLS AMG E-Cell. Unlike the standard SLS AMG, the E-Cell has such features as all-wheel-drive and zero-emission technology. In short, it's a glimpse at the possible future of the supercar.

Thankfully, that future still includes impressive speed because the SLS AMG E-Cell accelerates from 0 to 100 km/h in a respectably quick four seconds. That figure is nearly identical to the 3.8 second acceleration time achieved by the conventionally-powered SLS AMG, which makes use of a 6.3-litre, 571 horsepower V8 engine.

The SLS AMG E-Cell generates 525 horsepower and 649 pound-feet of torque from a rather unique powertrain: Instead of a centrally located motor, the E-Cell uses four synchronous electric motors mounted near each of the four wheels. The layout provides all-wheel-drive and a torque vectoring feature which allows each wheel to be selectively powered and braked depending on the driving conditions. When the time comes to slow down or stop altogether, the E-Cell relies on ceramic brake discs that are 40 percent lighter than conventional, grey cast iron brake discs. The brakes also includes anti-lock braking and electronic stability technologies adapted to the all-wheel-drive configuration.

In addition to its four-motor powertrain, the SLS AMG E-Cell incorporates a liquid-cooled high-voltage lithium-ion battery that's comprised of 864 cells and has an energy content of 48 kWh. The high-voltage battery also has a maximum electric load potential of 480 kW, which Mercedes-Benz says is "an absolute best value in the automotive sector."

Carbon-fibre has been used to form the E-Cell's transmission tunnel and is structurally integrated into the vehicle's aluminum bodyshell. When compared to aluminum, Mercedes-Benz claims the weight savings afforded by carbon-fibre is approximately 30 percent, while also being thinner. In fact, the fibres are supposedly ten times thinner than a human hair and a line of this fibre stretching from Earth to the moon would weigh just 25 grams according to Mercedes-Benz.

Mercedes-Benz will introduce a limited series-production of the SLS AMG E-Cell in 2013. The future of the supercar is approximately one year away.
