Apparently Mercedes-Benz innovators weren't satisfied with the 563-BHP output from the SLS AMG coupe. Road and Track caught a new Black Edition of the super-performance driving machine as it made a trip to the Nürburgring for testing purposes. The new release is expected to stay with the same 6.2-liter V-8 and dual-clutch 7-speed transmission but should have horsepower closer to 600.  If you have a cool $300,000 sitting around under your mattress and want to move to Europe, this could be just the car for you!
