The top four door coupe class contender’s next avatar, the 2011 Mercedes CLS was caught by the spy photographers testing in Germany. The spy mages reveal a bigger grille, a more prominent front bumper, LED daytime running lights and angular headlights. Interestingly, there is a third break light which finds its position in the bumper between the exhaust pipes. On the inside, the customary interior makes way for a more cost friendly E class type setup which is surely disappointing. Engine speculations for the 2011 model involve a number of petrol and diesel choices which includes a 3.5L V6 and a 5.5L V8. Also there could be a twin-turbo V8 powering the 2011 CLS with 544hp and hybrid version all of which shall be up for the grabs later this year. [via WCF]
