Spyshots: 2012 Mercedes GL Undergoing Winter Testing

The 2012 Mercedes GL SUV, which has been spotted a number of times, has now popped up in chilly Sweden, where it is undergoing some serious winter testing on snow and ice. The front of the vehicle is more easily seen than before, allowing us to get a much better look at the new headlights and the revised R-Klasse-inspired grille that looks a bit wider.

However, the rear is still heavily disguised leaving us guessing on what the back end will look like. It seems the GL, Merc’s wagon/SUV creation, will get front end styling attributes from the current E-Klasse sedan. According to the most reports, it will be underpinned by a stretched-out version of the next generation ML platform. The 2012 GL will feature LED daytime running lights on the bumper.

Meanwhile, the compact light clusters for the rear taillights will likely be part of the next-generation GL's look. The exterior revision might also include a friendlier face for the thuggish-looking GL, emphasized by a wider grill and a more aerodynamic nose.

Engines will likely still be shared with the ML model, such as the 3.0- and 4.0-liter diesels and the 5.5-liter petrol V8, all coupled to the brand's 7G-Tronic (7-speed) transmission. Options are likely to include a twin-turbo 4.6-liter V8 with 429 hp, while the AMG version could come with a twin-turbo 5.5-liter V8 with around 540 hp and 800 Nm (590 lb-ft) of torque.

While there is no official launch date scheduled, the GL is widely expected to be unveiled late next year.
