CLS55 AMG
Question for CL65 owners:
In this thread on the E55 forum, a fellow posted the results page for a shootout between the Ferrari 612, the CL65, and an Aston Martin (presumably DB12). In straight acceleration, the CL65 cleaned the 612's clock as expected, but the in-gear acceleration test gave an edge to the Ferrari.
However, this test is odd, claiming to show max times from 80km/h (50 mph) up in fourth and fifth gears. What is odd about it is that I know for a fact that in my CLK55, if I manually shift into fourth at, say, 60 mph and stomp it, the car will simply act as in full auto mode and drop down into second gear.
I'm wondering if this also holds true for the CL65; if so, it would basically explain the discrepancy, as the driver of the CL would have been forced to use less than full throttle. I maintain that this is the case, whereas the fellow who posted the test results dismisses this possibility and maintains that it is the 612's gearing...which I would think if true would allow it to win from a start as well, so I'm convinced that the downshifting is probably an issue.
Any CL65 owner(s) care to test this?

My CL55 has a selectable manual mode for the transmission. I believe the CL65 is the same.
I have not verified this specifically (4th @ 50mph), but in manual mode I'm very sure you could drive the car at 50 mph in 4th, put the pedal to the floor and the tranny will not downshift. At redline it will upshift.
Again, I haven't specifically looked, but at 50mph in 4th the rpm's would be low, therefore requiring some time for the heavy car to increase rpm's. The effect should be similar in the CL65.

Yes it true that they don't have same transmissions, but the gears are just the same, its just that the 55K has very much stiffened and strengthened gearbox and a different final ratio.
Anyways, what Improviz has said is essentially correct, but some AMG Mercs are coming with the Manual Mode which will not upshift at redline or downshift under heavy throttle. If this is applicable to the CL65 then the theory is invalid and elasticity acceleration in higher gears can be measured. But if the Speedshift "Hold" function is not available on the CL65, then the car should rocket away after downshifting automatically, and therefor gain a better time.
Suprising, a number of CL55/S55 owners here, yet none of them has tried this maneouver.....what the hell do you guys use your cars power for?

4th gear and floor it @50 and see what happens?
My girl-friend bought one 3 months ago and I drive it sometimes and this thing is stupid fast, and I mean it in a good way!
I will try this test next week 4th and floor it @50 and see what happens? I have a feeling it will kick down?
I'll let you know?
And pretty soon I'm going to take it to the drag strip and see if I can really get an high eleven second pass? On stock street tires. I'll let you guys know.

Bilal:
First off the CL's in manual mode upshift at redline. Read the manual or try if you can get your hands on one.
I can tell you what I don't do with my car. In a vehicle that will do eighty in second gear, I don't lug it down to 1700 rpm's in fourth (50 mph) and then punch just to see what happens. In manual mode I know that it will not downshift.

J.edwards, I am in no way saying I have experience with these cars, look at my profile to see what car I drive, but I must say, you have posted two conflicting statements.
For clarification, earlier AMG 55K models had a Manual Mode which allows you to change gear with the buttons. If in Manual mode, you are in too high a gear, and you floor it, the car will automatically downshift to a better gear. And if in Manual mode you were to pull any gear, it would upshift at the redline.
Now later AMG cars, have an Absolute Manual Mode feature. The C55/SLK55 and CLS55 of which I know have this function, in manual mode with these cars, regardless of whatever gear you're in, the car will not upshift at redline or downshift when in too high a gear.
The question remains, does the CL55/65 have either the earlier manual mode function or the latter? IF it has the latter, then it is possible to do an elasticity test. If the former, then the car should rocket away. I (think) that this is the gearshift logic of the earlier AMG models with regards to the CL55, however, you seem to disagree, regardless, with an abundance of torque throughout the rev range, acceleration is instant in all AMG's, I think we can agree on that?

Sorry, Bilal. Guess I just took offence at the question about what we use our cars for.
I don't see where my statements conflict, but let me try to clarify.
I have an '03 CL55 and I am reasonably certain that the CL65's function in much the same way.
To be honest I don't think I've driven the car in Comfort mode (This is indicated with a "C" and is similar to the "W" mode in my daughter's C32.), but in Sport mode or Manual mode the trans can be shifted with the steering wheel buttons or the gear shift. In Sport mode with the trans in 4th and doing 50 mph, if you put the accelerator to the floor the car will down shift, accelerate to red line and upshift. Except for the slight delay for the downshift, acceleration is fairly instantaneous.
In Manual mode (which has to be deliberately selected and is indicated in the instrument cluster with an "M" in front of the gear number) the car will not down shift except at the very lowest rpm's, i.e. when you stop at a light. The car upshifts at redline always ( My manual transmission GTI had a rev limiter to keep you from blowing the engine. Mercedes appears to have opted to control over-rev with the transmission). With the trans in 4th gear, Manual Mode and going 50mph (approx.1700 rpms), the acceleration is not as "instantaneous" as it would be if the trans were in optimal gear. I believe this is a result of the heavier car not being in its maximum torque range.
