In a move sure to make shoulders slump and people ask "Why is this happening?", Mercedes will not produce a CLK63 AMG -- which would actually be an E Class Coupe AMG. The axing is due to the CLK moving from the C Class platform to the E Class, and Mercedes' view that a hotted up E Coupe with the 6.3-liter would be too close to the CLS 63 AMG "both in positioning and price."
A similarity in price is easy to digest, but the overlap in positioning sounds more like Mercedes is afraid sales of the E-Class Coupe AMG would cannibalize sales of the CLS63 AMG. Even if that's the case, it's a shame that Mercedes won't even consider a limited run, since such a car would be sure to sell just as well, if not better than the E63 AMG Wagon. The decision also vaporizes an E Coupe AMG Black series, and that would have been something special.
