Historically, AMG models have been the hot rods from Mercedes but with the new SLC43, that is no longer the case. Under the hood is a twin-turbo 3.0-liter V-6 that makes a rather tepid 362 hp. Mercedes says it is just 0.1 second slower to 60 than the SLK55 it replaces, but it is also down by 53 hp and sure to run out of steam at higher speeds. The SLC43 has unique suspension tuning versus its SLC-class sibling, but from the exterior they look almost identical. How far the mighty have fallen.
