CLS 63 U.S. Release date
After the anouncement of the ML63 AMG, my sales person decided to inquire on the CLS 63. He just wrote me an e-mail 2 days ago and said that the general manager of the dealership confirmed April 2006. I have to make sure if it means official ordering or delivery....no matter what, it should mean a CLS63 for summer 2006.....
I'm kinda pumped about this new engine and now that they might be releasing it around mid 06. You think it would be coming out as an 07 model?
Next question is if you had a Dec-Jan delivery date for a 55 would you wait just a bit longer for this 63?
I already have a CLS 55, but I am on the list for another one -- I want the Performance Package (and the Designo Mystic White). However, the one thing that might cause me to cancel my order would be if the 5.5 supercharged engine is no longer available.
If I had wanted the performance characteristics of an M5, I would have ordered one!

Anyways, there has been alot of talk about the 63 engine being less torque than the 55K. But, lets take the 7 speed into consideration. After I did a simple math,(which I don't know if its acurate), the 7 speed will put more torque to the ground in 1st gear than the 55K and its 5 speed. Now I have the E55 right now. Its impossible to get all 519lbs down until you are past around 20mph. So the first 20-30 mph, you are only even with an 540i, but then after that, its lights out. The traction is very bad with the 55K motors. But I think, the 63 engine will put out even more torque based on the gears.
Just my 2 cents.

Possibly the shortest production run in history! If they are really moving this engine up to production that quickly, it's bound to wreak havoc on 55 models.
But, yes, the CLS55 production run will likely be one of the shorter ones in recent MB history.
[/QUOTE]new model will always affect the old model in a not-so-positive way but at least i'm enjoying the car now. life is too short to worry so much.

Just saw a review of the ML63 (which I think will be the first 63 out) and Mercedes claims the engine as the "world's most powerful naturally aspirated production eight-cylinder." Doesnt sound good for the K55.
This version his a few horses more, but has less lb-ft of torque. So what's the big story behind this engine?

Seems to be that the real equalizer is the 7-speed transmission. However, there's a reason the 5-speed is still on the V12 models and that is because it can handle more power. If you are into modding your cars, the 55K engine seems to be the better option due to the robustness of its components. If I wanted a high revving engine I'd lean towards BMW. I like the musclecar torque and power the 55K engine provides on demand. A higher revving engine may seem "sexier", but I love torque. As for the lack of 2 more gears, I dont think its that big of a deal. Some of the fastest drag racers run 2-speed powerglides. Personally, I'll wait until they drop a twin turbo 63 engine in the E or CLS.

well at least we can just spend a few more grand to have more hp than the 63 engine and the extra torque would be bonuS! hehe
