The facelifted CLS has been fitted with aggressive bumpers, which could mean that this particular prototype is wearing an AMG package. There is also a revised grille and modified headlights and taillights on the new CLS.
Spy photos of the interior show a similar layout to the current CLS but with a new steering wheel with metallic accents. The 2015 model will also feature a freestanding COMAND display that is significantly larger than its predecessor.
Under the hood, engine options will carryover from the current CLS with a range of petrol and diesel options.
