The unveiling of Mercedes-Benz' 2012 SLK is expected to take place in the coming months, but the German carmaker is missing no opportunity to build anticipation for the new model.

Following the leak of a promotional video that featured the new and unmasked SLK in all its glory, Mercedes-Benz has released a short video of Mercedes GP F1 driver Nico Rosberg behind the wheel of the new coupe convertible.

While not the most polished video around, the new footage offers one of the first impressions of the new SLK's sound, along with its Magic Sky Touch polarised roof.

Power for the2011 Mercedes-Benz SLK is expected to come from the company's 2.2-litre BlueEfficiency four-cylinder twin-turbo diesel, developing 152kW and 500Nm of torque.

Petrol engines are also expected, with talk of a twin-turbo version of the company's new 225kW 3.5 litre V6 on the cards for a AMG version of the new SLK, developing around 260kW.

Exactly when Mercedes will reveal its hand is unknown, although January's Detroit Auto Show - where BMW will show its new 1 Series M Coupe - seems a strong chance.
