I agree with Matt, comparing your S63 to a car that is 25+ years older is ridiculous, guess what your S63 is also faster than Nick Mason's $30Million Ferrari GTO..and your point is?
Lots of incorrect responses here regarding the original "Hammer" it is...
In a nutshell: A plain Jane 4 cylinder W124 that was bought brand new in late'85-'86 by AMG and completely dismantled and fitted with the 5.6L block from the 560SEC\SEL\SL and AMG's own (proprietary) quad cam 32V heads. It ran on CIS mechanical fuel injection and made 385-400hp.
"Hammer" was a perfect description that Road and Track casually used when they tested the car and it stuck.
If you want to really hit the nail on the head (to be chronologically correct), AMG built the very first variant of the "hammer" back in 1982/3 when they put the 5L from the W126 S-Class into a monochromatic candy apple red W123 Coupe with beautiful Recaro C's and Penta \ Ronal wheels. ITs a well known car for us '80s car and Benz \ AMG geeks
