Today’s Mercedes-Benz event at the Circuit de Catalunya in Spain was supposed to be all about the presentation of it’s new Formula 1 car during the first day of the 2012 season’s official tests.

Yet the 2012 F1 racer wasn’t the only Silver Arrow that was launched at the Barcelona track: as you can see in the video that follows, Michael Schumacher arrived on the pit lane driving the brand-new 2013 model year SL63 AMG.

Like the standard versions of Mercedes’ sixth-generation roadster, the AMG-tuned model uses a new chassis built of aluminum and magnesium which is lighter, yet much stiffer than its predecessor.

The SL63 AMG is set apart from the regular SL models by a more aggressive body kit. It includes a redesigned grille, a front bumper with bigger air intakes, specially designed LED daytime running lights, wider sills and a new rear bumper with an integrated diffuser and four exhaust pipes.

The hottest SL also sports “V8 Biturbo” badges on its sides, indicating that under its hood lies the new generation of Mercedes’ twin-turbocharged 5.5-liter V8 that also powers other AMG models like the 2012 ML63.

The force-fed V8 pumps out a generous 529bhp while at the same time it is 30 percent more fuel efficient than the previous generation SL63 AMG.
