Mercedes-Benz has announced earlier that it will develop an electric version of the Mercedes-Benz SLS gull-wing supercar. Well, Mercedes-Benz just debuted its first prototype SLS E-Cell in luminous yellow paint. The Mercedes-Benz SLS E-Cell is powered by four electric motors with two motors at each axle, which are synchronized with a reduction gearbox for an all four-wheel drive setup.

The four motors are rated with maximum of 12,000 rpm, that is more rpm than any combustion engine can dish out. The combined power of four motors churn out a total of 526 horsepower and 649 pound-feet of torque to the wheels, which enables the Mercedes-Benz SLS E-Cell to sprint from 0 – 60 mph in just four seconds.

Behind the energy source are the lithium polymer batteries, which split between the center tunnel and a box mounted behind the cockpit to give an even weight distribution. The lithium batteries have enough juice to crank out 480 kilowatts on the fly, and that is an equivalent to 643 horsepower.

With so much juice flowing, two separate cooling circuits are needed to manage the temperature of the battery packs and related power electronics. These circuits help warm up the battery during cold start and cool it down during driving. Since the Mercedes-Benz SLS E-Cell is lighter than the standard gasoline version, to keep it on track, an extendable front splitter and a rear diffuser are used to provide extra downforce.

With pure battery power and high performance, expect to see the Mercedes-Benz SLS E-Cell to come with a hefty price at around $270,000. The SLS E-Cell prototype is currently a fully drivable version, and we can expect it to arrive by early of 2013.
