Spy-photos of the upcoming 2012 R172 SLK55 AMG
Mercedes has been testing the upcoming 2012 SLK55 AMG on the ring and photographers have captured the newest test model. The sideskirts and front fascia are more aggressive as expected along with the typical oval shaped quad exhaust. The question remains, what motor will it have? The current rumor is that it will have an M157 twin turbo based variant just without the turbos. We find that a bit disappointing as if going the naturally aspirated route at least give it the M156 out of the C63 AMG. This little car has a lot of potential but Mercedes holds the SLK back to prevent it from stepping on the toes of its big brother AMG's.
