Spy Photographers have caught the 2012 Mercedes-Benz GL-Class testing with the Mercedes SLS AMG Roadster.
Though the Mercedes GL is heavily camouflaged, you are still able to see the larger grille, similar to that of the updated R-Class, bold front fascia and the overall larger design. The GL prototype shown in the spy photos is sporting AMG wheels and a high-performance braking system that may signify that it is a GL63 AMG but could just be a standard model with the AMG Performance Package.
Engine options are likely to include a twin-turbo 4.6-liter V8 with 435 PS (320 kW / 429 HP) and a 3.0-liter turbodiesel with up to 258 PS (190 kW / 255 HP). On the other hand, the GL63 AMG is expected to use a twin-turbo 5.5-liter V8 with 544 PS (400 kW / 537 HP) and 800 Nm (590 lb-ft) of torque.
As for the SLS AMG Roadster, it will feature a 6.3-liter (6,208cc) V8 with 571 PS (420 kW / 563 HP) and 650 Nm (479 lb-ft) of torque.
While the GL is does not have a scheduled unveiling, it is expected to be unveiled sometime next year with the SLS AMG Roadster is scheduled to debut at the Frankfurt Motor Show.
