Spyshots: Mercedes E63 AMG testing new SLS brakes at Grossglockner?

While the new Mercedes E63 AMG was released to the public two months ago at the New York Motorshow, this E63 AMG was caugth testing the AMG brakes at the Grossglockner pass. The upcoming SLR successor, the Mercedes SLS, was also seen in the area of the Grossglockner. Speculation suggests that AMG uses the E63 AMG to test different brakes and brake settings for their SLS Gullwing.

It’s no secret AMG used similar brakes on the Mercedes SLS mule that was caught testing before.
