SLS AMG: Mercedes-Benz announces an all-electric version of its supercar

The SLS AMG is a supercar planned by Mercedes-Benz this year, copied from the classic Mercedes-Benz 300 SL in the 1950s, and its biggest feature is the design of the door with wings like a seagull, which also has the nickname "Gullwing". The car is powered by a 563-horsepower 6.3-liter V8 engine that can accelerate from 0 to 100 km in 3.8 seconds. The SLS AMG is expected to be officially unveiled at the Frankfurt Motor Show in September, with production going on sale in 2010 or 2011.
