It took one fat growl of AMG's latest 6.2-liter V8 to make us converts to the Merc speed-shop's naturally aspirations. It's such a well-balanced puller in the CLK63 that we'd consider getting "there's no replacement for displacement" upside-down on our lower lip, just to be reminded. If we were, say, a famous photographer who had to get his cameras, lighting hardware and assorted strobes from, say, Monaco to Geneva in an afternoon, we'd have taken a knee-jerk lunge at the Audi RS4. But our fictional decisionmaking will be far less crystalline when the next C-Class hot wagon emerges from the AMG shop. The new C63 wagon, spies say, will be tuned for about 420 hp, though the big-block has been known to breach 500. Look for it at the Frankfurt show.
