After reading in the e55/e63 forum that the new 63 engine is not making anywhere near the power MB claims why would one not get the cl600 instead? It seems the price difference is marginal but the acceleration #'s will be substantially better in the 600. Especially in the heavier CL (than the E) with the loss of alot of torque with the 63 engine compared with the 55k .
I realize the suspension and braking should be better in the 63 but the engine sure seems lackluster!

 

You're right on the money, and to alleviate your concerns, the AMG brakes are not exactly the highest quality, so you're better off getting a set of Brembos if you really care about performance anyway. As for suspension, a pig is a pig, AMG versions are just stiffer pigs. 600 all the way. Sales for higher end 63's should be rather lackluster.

 

Sales for all the 63's in any model have been lack luster. They are sitting in dealers inventory all over the US.

 

I must say however the 63 looks AWESOME. I wonder if you get the cl600 with the sport package it will look anything like the 63??

 

It does look good though...

the hyundai tiburon has stepped up its game...looks sharp.

 

your original statement isn't acurate. it makes the hp it says, but not more like the 55 is suspected to do. in addition, there are several new technological improvements over the past model.

 

there were a couple of low dyno's for the 63 motors, and then there are some good ones....

here is an E63 making 408 rwhp and 363 rwtq....

http://www.dragtimes.com/Mercedes-Be...lip-10144.html

you might get similar HP to the outgoing 55k motors, but the torque could be 100 pounds less than the 55k motors....

 

isn't it generally agreed that the 63 has a higher hp rating than the 55? no?

 

Most the 55 engines were underrated when it came to the hp figure of 493hp.

Mine for instance produced close to 516 hp at the crank using a 18% drivetrain loss. (437.4 rwhp).

 

But why is the emphasis so much on HP, when its the torque that accelerates the car. So far, the HIGHEST torque figure I've seen for a stock 6.3 is 363 at the wheels. The LOWEST torque I've seen for a stock 5.5S is 440 at the wheels.

 

You can't seperate the two.

HP is gotten from torque.
I think... torque * 5250 / rpm = HP.
After you to all the translations from rotational force (what torque is) to (I think) linear power, you get HP. All the math/car nuts summed it up in that simple formula.

So -- HP is the rate at which torque is applied.

Also you want to look at when the hp and torque come in. You won't want to drive a luxury sedan like a Honda S2000 wringing it until redline, you want to be able to cruise at a thousand or two rpms, relaxed like.

 

Plus those new AMG 5 spoke wheels are reason enough.

 

Maybe we need to re-think some earlier '63 thoughts ?

The big Benz for the serious enthusiast
By Ken Gross Email
Date posted: 11-08-2006

Last year, Mercedes-Benz's stunning CLS "coupe-sedan" stunned the high-roller set with its racy good looks. If you've been wondering what this sexy saloon would look like with just one pair of doors, get out your checkbook. Here it is, the 2007 Mercedes-Benz CL63 AMG.

We've already delivered driving impressions of the delicious CL550 and decadent V12-powered CL600, but the AMG-tuned CL63 is a different animal all together. It's the sharpest knife in the CL's drawer. The big Benz for the serious enthusiast.

V8 power: taken to the max
Naturally, the wizards at AMG, Mercedes' in-house hot rod shop, couldn't wait to get their hands on the S-Class-based CL. But rather than breathing more fire into the CL550's 5.5-liter V8, AMG developed the CL63's all-aluminum, smooth-as-silk 514-horsepower 6.3-liter V8 in-house.

The AMG-exclusive four-cam alloy V8 features variable camshaft adjustment, a highly rigid closed-deck crankcase, revolutionary new friction-fighting cylinder coating and oversized bucket tappets to suit its high-revving valve train. Its electronically controlled fuel injection system borrows from Mercedes-Benz practice, but incorporates new components to match this engine's performance potential. (Need we remind you that this is a normally aspirated power plant?) If need be, forced induction can (and perhaps will some day?) loft its output to well over 600 hp. Meanwhile, we're not complaining.

A stock CL550 packs 382 hp and 391 pound-feet of torque. The CL63's 6,208cc V8 makes 514 hp and a whopping 465 lb-ft of deep-seated torque, which makes it the world's most powerful, normally aspirated, series production V8. In other words, the CL63 really doesn't care which gear it's in; it'll boogie whenever you stomp on it.

The precise Speedshift 7G-Tronic automatic gearbox lets you match moods and roads with paddle-shifted Comfort, Manual and hyper-quick Sport (our favorite) settings. The Manual setting shifts 50-percent faster than the Comfort mode, 30-percent faster than the Sport mode, and lets you stay in your chosen gear at wide-open throttle and at kick down, so you get every bit of that horsepower, when you want it.

Fast company
Fire it up and a basso-profundo, un-Merc-like rumble from a quartet of oversize exhausts hints of wickedness under its sharply raked hood. Although the CL63 AMG gives away 36 hp to the Bentley Continental GT W12, Mercedes says it trounces the heftier Brit GT to 60 mph by 0.4 second and is just as quick in that sprint as the lighter BMW M6. The last M6 we tested hit 60 mph in just 4.6 seconds. Even better, Benz says the CL63 AMG is nearly as swift to 100 mph as Ferrari's 612 Scaglietti, for about half the sticker.

Like many German high-liners, this car's top speed is electronically limited to 155 mph, but you can opt for a Porsche-chasing performance package with a 186-mph limit.

No options needed
As befitting Stuttgart's range-topper, every conceivable handling and stability aid is standard, starting with improved Active Body Control (ABC), combined with AMG's supple-but-sweetly-firm sport suspension. The steering is precise, spot-on center and very consistent. Toss this big baby into a long sweeper, as we did on *****in' Bavarian back roads and you'll be amazed. There's no sturm, no drang, and virtually no body roll or frantic tire squeal from the huge 20-inch Yokohamas — just great grip and plenty of it.

A special AMG-developed high-performance braking system uses unique twin sliding calipers for the front brakes, single sliding calipers for the rears. The CL63 AMG's massive, fade-resistant brake rotors (15.6-inch front, 14.6-inch rear) are made of lightweight, race-inspired composite material, yielding outstanding sensitivity and surprisingly short stopping distances, time after time. ABS, brake assist and adaptive braking are all included.

We hustled the new CL63 AMG through tortuous mountain passes from Kitzbuhl, Austria, to Munich, Germany, reveling in this big coupe's ability to accelerate smartly, shrink distances, and entertain us royally with its split-second shifting and deeply satisfying exhaust note.

Looks are everything
AMG's stylists ensured you won't mistake their CL for the tamer Stuttgart version. There's a big fishmouth air intake under the grille, smart-looking titanium-painted headlamp lenses, distinctive aerodynamic side skirts, unique taillamps and rear fascia wrapped in an eye-pleasing wedge shape that's reminiscent of M-B's delicious CLS sedan-coupe. Inside, swathed in Passion leather, whether you choose walnut or aluminum trim, you're enveloped in luxury.

On sale next June for an estimated $125,000, the limited-production 2007 Mercedes-Benz CL63 AMG will raise the supercoupe bar, for just a few hundred enthusiasts. Better get in line.

Edmunds attended a manufacturer-sponsored event, to which selected members of the press were invited, to facilitate this report.

 

Even better, Benz says the CL63 AMG is nearly as swift to 100 mph as Ferrari's 612 Scaglietti, for about half the sticker.

Wont belive it till i see a video of that happening!

 

Because you can't afford a CL600/65 and CL55 is not available.

 

So why's my M3 quicker than a NA Mercedes V12 and 5liter V8?

Not to mention Formula One cars with their puny, low-torque 2.4liters

 

the guys in AUTOMOBILE magazine just asked the same question as I did when I started the thread, WHY a CL63?
The 600 is a better car? If you want faster than 600 get 65? Seems funny that the AMG63 car will be noticeably slower (not the 65) than the 600. get the 600 and maybe renntech it for 6500 bucks to run with the 65. Only smoother thank the 65. hehehehe that ssounds like a plan to me.
but like I said the 63 LOOKS cool. it isnt that cool. the 600 is.

 

it seem s most carping about the 63's come from non-63 owners. i traded my modded 55 on a 63 and am delighted- a much more complete car and very fast. i wouldn't think of going back to my 55. i'll bet other 63 owners feel the same.

 

yes I see your point, in terms of the e class and all that bickering. but the CL class which is heavier and offers a larger engine than the 63 I am baffled at why there is the 63 at all offered in this line. or the S class for that matter.
If the so called AMG version is slower than the non AMG version what is the point?

 

your m3 is not quicker or faster than an SL600. My dad has one and walked me in my e55k. I have burried an m3 a month for the last 3 years.

 

That's impossible, M3's are faster than Veyron's

"NA" stands for "naturally aspirated." Last time I looked, the only SL600 that could beat an E55k was turbo'd.

While neither are slow, the R230 and R129 SL600s are hugely different propositions.

 

ahh your right sorry for missing the NA... I honestly thought it meant the "North american" versions.
I can remember back to the older sl600's that thing was pretty damn fast. but not like th TT ones
sorry for the confusion.
but to furhter my original point the new S class will not ever be available with a 63 engine. just 3 trims 550,600,65. that tells me right there that there is no reason to have the 63 in the CL lineup.

 

No probs at all. There's gonna be some great deals on the old CL65's when the new one comes out.

 

Actually, S63 will be available. And I agree 100%, 63 engine should only be offered on cars that don't have the V12 bi-turbo option. Who in their right mind would choose a NA V8 over Bi-turbo V12? Especially in such a heavy car....

P.S. And the M3 is faster than the old NA SL600 because its more than 1,000lbs lighter. If an M3 had the NA V12 from the old SL600, it would've been obviously faster than an M3 with its stock V6.
