Now that the AMG versions of both the AMG versions of the C-class and the E/CLS-class have the same engine, it is likely that C-class will outperform the E/CLS-class due to lighter weight. Sure its only supposed to have 450hp VS 500hp in the E-class... but I'm willing to bet they will put down almost the same power (same thing with current E55 and SL55, while marketing hp #'s are different, dyno's are very close). And if it is detuned from factory, it will only require a minor ecu tweak to put down the same numbers as E63/CLS63. Now... do you guys think its right for Mercedes /AMG to put make C63 as fast as E63/CLS63? I would personally be very pissed off if my E63 or CLS63 gets smoked by a much-cheaper, "entry-level" C63. I can't imagine how I would feel if my top of the line $150,000 S63 gets smoked by C63! The performance difference between C55 and E55 was huge, now it looks to be miniscule between C63 and E63/CLS63/S63/CL63.

it'l be detuned..
so what you're saying..
a modded C63 "could" outperform a stock E/CLS63.. modded vs. stock
but then.. mod the E/CLS'.. different story different prospective..

Efivefive

I would have thought the detuning would be a bit more involved than just ecu???????..............exhaust system maybe?????

At the moment it is just speculation, on how easy it will be to get the power of the engine upto the same level as that of the E/CLS 63.

I suppose this would add more fuel to the Hammer 1 and Hammer 2 theory????
......perhaps the new E will be getting a blower????......or maybe 2????...wow!!!!!!

Blue Arrow

I believe its a good sign of things to come.
c32 vs e55
c55 vs e63
c63 vs ???

Ted Baldwin

......he is not really talking about a moded C63. The idea of factoory detuning is bs. The engine will be the same and output the same. That C63 will be as fast or probably faster than an E63 or CL63 is lilkelly and not unique. Afterall the W211 E55 is faster than the more expensive an up market SL55, CL55 and S55. Right?

Has anybody ever put a CLK63 on the dyno? That is supposed to be a detuned version of the 6.2liter (30 less hp or so) but I wouldn't be suprised if it puts down the same numbers as the E63, CL63, S63.

If they are around the same whp numbers then I wouldn't be suprised if the up and coming C63's engine is identical to its bigger brothers.

What transmission will the C have the 5S or 7S?

amgme

7s

Addicted2Speed

He is right. Factory detuning is indeed BS. E55 does not have less hp than SL55. The truth is that C63 will dyno almost exactly the same as all other 63... if not, a simple 500$ ecu tune will make it dyno the same.

DirtyVegasMB

You're paying for much more than just speed with bigger bodies. Plus, you shouldn't expect the bigger car to be the fastest one... having said that, I do think that big body 63s are underpowered compared to the current and past line up.

MOROSO55

Im sure the 7speed

CyE55

Exactly...different strokes for different folks. Why would anyone be upset?
Get the car you're like more and move on.

In '01, the CLK55 AMG was the fastest one in the lineup: it was slightly faster than the E55, and considerably quicker than both the S55 and CL55. Of course, once the supercharged models came out, this got turned on its head, but it was fun while it lasted!

TopGun32

the latest spy photos shows the C63 with quad tips, just like the CLS63 and C63.

therefore exhaust tuning should be the same (atleast the hardware is). Probably a bit smaller TB and a detuned ECU to round up to 475hp (like CLK63).

It would be a hard choice.. (used E63 or new C63).

I would be the C63 would have almost the same interior space as the W211 and about 400lbs less.

I say.. the C63 would be about equal to the E and CLS in performance.

AMG_55

i dont believe ive ever seen 208 amg's being faster than 210's. got a link or something?
i think its mostly due to the 245's on the 208 and the 275's on the 210



as for the c v. the rest, it should be just as fast detuned or faster with the full 500+hp
supposedly the cl and s are putting out 520, the e and cls are at 507

they are all different cars for different markets though, i dont think anyone would car, to them it would be "just a c class"

2MANYCARS

It would be interesting to see what magazines' reviews say about them. I strongly believe the C63 will have the exact same spec as the CLK63 and I'm expecting to see a MSRP to be in the low 70s.

Improviz

Perhaps I should have added a "when properly driven" disclaimer. The E55 was about 300 pounds heavier, but it did have a traction advantage. However, with practice, a CLK55 could be made to launch pretty agressively. And with a slightly better weight/hp, once rolling, physics took over.

Or you could throw a set of 275's on the CLK on a set of 210 E55 18's, as I finally ended up doing, and take care of it thataway.

But there was definitely a somewhat higher margin for error in the 210, although even with the 275's, it was no picnic to get out of the hole quickly (nor is the CLK!!).

AMG_55

you also have to consider that, at least claimed by mb, the clk had less hp and much less tq

Improviz

So, as claimed by MB, does the E55K vs. the S55K, SL55K, and CL55K, and we all know what a load of that is from the dyno runs.

And I personally don't regard 3 hp and 6 lb-ft of torque as "much less"; my owners' manual, which I have scanned and published in these forums before, lists horsepower as 346 and torque at 384 respectively. Benz revised their figures after the cars were released, but again: look at the dyno numbers for the 55K and compare them to the SL55 or CL55.

Oh, and MB also claimed that the 210 E55 ran 0-60 in 5.4 seconds, while for the CLK55 they claimed it in 5.2 seconds.

AMG_55

i though it was 342hp v. 355hp and 376lbfttq v. 391

i ran a 210 in my 209 and it was dead even, i also ran a 208 and evnthough it was NOT a perfect race (he started behind me etc..) i easily put 2 cars on him up to 70 or so

you never know with the mb marketing


for a rare car

Improviz

No, the 210 E55 was rated at 349/391:. And as I said before, Benz did modify the 208 HP/torque figures from what they were in my owners' manual (mine was an early build), but my owners' manual says 346 hp and 384 lb-ft of torque.

I ran a C55 from 80-140 and even though he jumped on it first, I hung right with him the whole way. Same rated hp as yours, right, and lighter, yes?

Anyway, look into "production tolerances", or read this article for an example of how ymmv when it comes to hp ratings. Or better still, look at both of the Car & Driver tests for the 210 55. The first car they tested ran a 4.9 0-60 and 13.5 @ 105, while the second car tested ran a 5.5 0-60 and a 13.9 @ 103. Some cars are hotter from the factory than others, known fact....

Wel, what I do know is what the dyno numbers say, and you are free to look at dyno plots for the "469 hp" E55 and CLS55 and compare them to dyno plots from the "493 hp" SL55, CL55, S55....two things quickly become apparant: 1) the cars all produce very, very similar levels of wheel hp, and 2) NONE of them are producing claimed hp; most are up in the 520+ crank vicinity, meaning that *all* of them have pretty dramatically underrated horsepower numbers.

And this is not something I pulled out of the air, or that is solely my opinion; it is widely known on these forums, and there have been plenty of threads discussing it, so I am hardly reporting something new and unknown here.

Thank you. Still love it, plan to hang onto it for awhile.

AMG_55

i agree with you, all (same) cars are a little different
i'm aware of the 55k's being underrated also (my mom has an e55 )

Improviz

It's entirely dependent upon how many Doppelbocks the assembler had over lunch!

Well, there you go, then!

I figure that the C63 will suffer the same problems as the CLK: T-R-A-C-T-I-O-N!! As long as these jerkwads at Mercedes continue refusing to do the same thing their competitors at BMW do, which is to give their flagship sports sedans/coupes limited slip diffs, these cars' off-the-line performance will suffer, along with their performance at the track.

One hopes that they will, at least, have the courtesy to make it a bloody option, although at these price points, it should be standard, full stop. GMs costing far less have this, and so should they, the tightasses (major pet peeve of mine, in case you can't tell! ).

Can Drive 55

Maybe our two cars should meet each other over a cup of coffee or something. Like maybe when it quits raining?

It's never going to stop raining here. My slk hasn't been outside the garage in so long I'm afraid it's going to forget how to move.
