The Mercedes-Benz SLS AMG Electric Drive coupe will offer 740 hp, all-wheel-drive and a body that looks like liquid metal. Mercedes had to go to extensive lengths to make sure the electric-powered SLS AMG would be one-up on its gas-powered peers. Powering the AMG Electric Drive Benz are lithium-ion batteries developed with the help of Mercedes Formula 1 engineers, packed into the tunnel where the drivelines and transmission used to reside. Using two electric motors on each axle, Mercedes was able to program the SLS AMG so that each wheel can be spun and braked independently, which provides better handling. Its 60 kWh of battery storage is the same as the mid-range version of the Tesla Model S, and Mercedes said the SLS can go about 155 miles on a single charge. The cost (in Germany) will be about $536,804, making it the most expensive vehicle Mercedes-Benz has sold since the demise of Maybach; it’s also double the price of a new Ferrari 458 Italia.
