Mercedes has announced the SLS AMG Roadster- the topless version of the SLS AMG Gullwing supercar will go on sale this fall to the public, or at least those that can afford its price tag. It features the same drivetrain as the hard top gullwing coupe, but has an automatic soft top that can be retracted or extended in 11 seconds, at speeds of up to 31 mph. It's also equipped with the AIRSCARF system which Mercedes say allows the car to be drive top down in any sort of weather.Source: carscoop
