First official images of the Mercedes-Benz CLA have surfaced the Internet, ahead of its January public debut in Detroit.

After months of preliminary info, rumors, spy photos and videos, we finally get to see the CLA before its arrival at 2013 NAIAS. Looking fairly attractive, the baby CLS has inherited a lot of its design cues from the Style Concept Coupe, including the "floating dots" front grille.

Based on the new A-Class, the CLA is about 4.60 meters (181.1 inches) long and will be offered at first with three gasoline engines and a diesel: CLA 180 with 122 HP (90 kW), CLA 200 with 156 HP (115 kW), CLA 250 with 211 HP (155 kW) and the more frugal CLA 220 CDI with 170 HP (125 kW). In September next year, Mercedes-Benz will reveal the range-topping CLA45 AMG which is rumored to offer 335 HP (246 kW).

The German carmaker has already confirmed a new type of 4MATIC all-wheel drive system for the CLA.
