2014 Mercedes-Benz SLS AMG Electric DriveEnlarge Photo
Finally, though it won't qualify as anything remotely mass-market, the 2013 Mercedes-Benz SLS AMG Electric Drive will have the power to move a very select group of owners, starting in 2013. It's the pure electric version of the gullwing supercar, powered not by a big V-8 but instead by batteries and four electric motors for a total of 552 kilowatts of power and 737 pound-feet of torque. Mercedes pegs its 0-62 mph time in 3.9 seconds, and sets a top speed of 155 mph--roughly the kind of performance you'd find in other AMG models, if not quite up to the gas-powered SLS. Recharging takes 20 hours on a standard Level 2 charging station, or three hours on a quick-charge station. The base price would be the equivalent of a heart-fluttering $435,000, but it hasn't been confirmed yet for U.S. customers.
