Spotted undergoing testing at the company's R&D center in Sindelfingen, Germany, this disguised prototype is likely packing many of the updates that were recently applied to the A-Class hatchback with which the CLA shares most of its underpinnings. As you can see, the front end is camouflaged to disguise the shape of a new grille, bumper, and headlights. Expect similar revisions to be applied to the back as well.
Don't expect any drastic mechanical changes in most of the models, which will surely cut the svelte model's fuel consumption and carbon emissions incrementally. We can likely look forward to the arrival of the new AMG version that will hopefully pack the revised 2.0-liter turbo four that produces 381 horsepower and 350 pound-feet of torque in the updated Mercedes-AMG A45 – a not-insignificant boost of 36 hp and 18 lb-ft over the existing version.
Mercedes won't pass up the opportunity to update the interior with new trim and equipment. That should mean a bigger infotainment screen, a new instrument cluster, and even more comfortable seats. Look for all this and more when the revised CLA arrives sometime next year, likely as a 2017 model.
