Our intrepid spy photographers not only caught the Estate version of the facelifted 2011 C-Class, but this time they also managed to snag some pictures of the car's redesigned dashboard, which will be the same for all body styles including the sedan and the new addition to the range, the coupe.

Taking styling cues from the larger E- and S-Class models, the prototype C-Class facelift pictured here gets a newly designed instrument panel that extends to include the display screen over the new center console, which has new controls and air-vents.

On the outside, the light camouflage hide a series of subtle design tweaks that include gently massaged front and rear bumpers, small changes to the design of the headlamps and tail lights plus a more contoured bonnet and front grille.

There's not much info going around about the engineering upgrades, but buyers should expect some mechanical tweaks to improve fuel economy and reduce CO2 emissions across the range.

The facelifted C-Class sedan and Estate models along with the all-new Coupe variant (see our most recent spy shots here) will go on sale next spring.
