Avoe and fanch are right...the CLK 55 does
not have the supercharged V8 of the SL55, S55 and E55 AMG.
And I have to correct Avoe: AMG already dismissed all rumors that they plan a special edition of the CLK 55 with the supercharged V8.
But if you guys are interested in AMG:
a few days (or weeks
...I won't give details because I don't want to put some people into trouble) ago, I met several Mercedes engineers on a testdrive on the Autobahn. We talked about 10 minutes at a parking lot and they've been very nice to me because I was in my ML55 AMG.
To prove that I don't tell stories: the "convoy" of mules included a Maybach (surprisingly camouflaged) with license plate from RT-, a new E-class stationwagon (camouflaged too) and a CL 600 with the new 500 HP V12.
Well, first at all they told me that AMG plans a AMG version of the V12 engine with 500 HP. Nice suprise.
The other interesting thing: I told them that I own a 996 Turbo and one of these guys (older one) told me that Porsche has to dress warm in the next few years because AMG plans a few "extreme" cars to cope with ALL available Porsche models.
Excessive weight has been a problem but AMG already is integrated into new model development to make sure that the base of new AMG models will be good.
"We have the knowledge, we have the money and we have the best engineers, why shouldn't we be able to build better sportscars than Porsche" one younger guy told me. He seemed very proud of his job.
I also asked about a new ML 55 AMG with the supercharged V8 but they all just had a big grin on their face and one of them said "well, the Cayenne is nice but Mercedes won't allow Porsche to claim the fastest SUV on earth. We'll surely get this title back, it is just a matter of time".
