Mercedes' successor to the Mercedes-McLaren SLR spotted in the arctic snow. The new super car is expected in 2010 and will come with a twin-turbo V8 producing somewhere around 600 hp.

Here are some recent spy shots of the Mercedes Gullwing as it begins it's cold weather testing in temperatures as low as -26° C (-14.8° F).

The Gullwing will be Mercedes' own version of the successor to the Mercedes-McLaren SLR after its divorce from McLaren on that project. McLaren are working on their own version too.

Details are not definite on this model so all we can say is that it is expected in 2010 and will have a twin-turbo V8, connected to Mercedes' 7-tronic automatic gearbox, with somewhere in the neighborhood of 600 horsepower (441 kW).

The new Gullwing is expected to carry the label SLC and it will become the first model in the Mercedes line-up to be produced exclusively by the AMG tuning arm.

Take a peek at the pics. Enjoy.
