The German based automaker Mercedes-Benz has just released some spy photos of the 2014 Unimog and Econic undergoing cold weather testing in Finland.

Mercedes-Benz Unimog and Econic in question are actually prototypes which have been heavily camouflaged. The main features will be for Unimog a prominent single bar grille, while the Econic adopts an upright front fascia.

The improved models will be launched this fall, and as the officials put it, the vehicle will feature "extensive design innovations to the interior and exterior."

Also, the trucks will be equipped with new BlueTec-6 diesel engines that meet Euro VI emissions standards.

The Mercedes-Benz Unimog and Econic, for the 2014 model year, have been tested icy roads, tackling mountains of snow and temperatures as low as -30° Celsius (-22° F).

Previously they have been tested in hot weather testing in Granada, Spain where they were subjected to temperatures in excess 45° Celsius (113° F) and attitudes of 2500 meters (8202 feet) in the Sierra Nevada mountains.

“Whereas the winter trials in Finland test the vehicles for their adaptability in extreme cold, in Spain we make sure that heat and different altitudes do not present a problem. This ensures that our customers can rely on our vehicles for all uses and at all times”, said Walter Eisele, the head of Production and Development for Mercedes-Benz Special Trucks.
