When a Formula 1 champion is testing a future car we know to expect something big. This is the case with the next generation Mercedes E63 AMG lately being caught testing by Mika Häkkinen. The official debut will be made in 2009 at the Frankfurt Auto Show.

The 2010 E63 AMG will be powered by a 6.2-liter V8 under the hood, good for an output of 514 hp. Thus the RS6 is still the fastest car in the segment. But maybe we will see a Black Series version from AMG with output somewhere around 600 hp.
