After dozens of spy photos and speculative artist renders since 2010, Mercedes-Benz has finally revealed the all-new Mercedes-Benz SL63 AMG in conjuntion with the launch of the Mercedes AMG Petronas F1 W03 race car in Spain today. The announcement comes less than two months since the 2013 SL-Class made its world premiere at the North American International Auto Show in Detroit.

The Mercedes-Benz SL63 AMG features the familiar M157 twin-turbocharged 5.5-liter V8 engine that produces 530bhp (395 kW / 537 PS). Thanks to the all-aluminum bodyshell and assorted magnesium components the SL's body now weighs 242 pounds (110 kg) lighter than its steel bodied predecessor. The result is a vehicle that achieves greater performance running 0-62mph in 4.3 seconds (4.2 seconds with the AMG Performance Pack) and 30 percent combined fuel consumption savings with 28.5mpg and CO2 emissions at 231g/km compared to 328g/km for the previous generation.

In the videos, the SL63's appearance is brief but comes as no surprise as its front end looks quite similar although just slightly more aggressive than the standard 2013 SL-Class. Its front bumper fascia has larger air intake pockets with LED daytime running lights sitting inside and the grille features an all-new split-wing design. Side skirts are the same as the SL-Class while the rear end with its diffuser and four trapezoidal exhaust tips were revealed in previous spy photos.

Stay tuned as an official media release with more details and photos are expected tomorrow.
