looks like we'll have some competition from the non-AMG CLK550 :v
if the engine is a 5.5 liter one, as the numbers imply and i'm guessing similar to ours, anyone care to speculate as to how it'll make more hp than us?

TopGun32

it okay... for the CLK55 members. They will be able to jump into a CLK63. This is confirmed by the AMG Director.

As far the E, CLK 550, I think it is a very good move. BWM has now the 4.8L 360hp, Lexus 4.6L 380, Infiniti will come about the same. But the advantage for the MB will be the 7 speed.

Lexus has developed an 8 speed for the flagship LS, not sure if the GS will get this transmission.

For us the C-class AMG, we don't know what AMG will do?

will it be a C55 with a 400+ 7 speed engine?

or

C63 with a detuned engine and 7 speed?

hm cars are definitely getting faster these days. the 7-speed tranny should be a huge aid in acceleration. i definitely need to get some pulleys and ecu now. pretty soon i will have to do headers, ignition, then port the heads and go with big valves, custom camshafts, and have a customized intake manifold and throttle body design just to keep up! lol j/k. i really do wonder what is feasible for the c32's motor though in street trim without going overboard. 500hp maybe?

i belive benz's new philosophy of higher-revving n/a motors coupled with 7-speed transmissions will manifest itself in greater improvements in acceleration compared to current 55's than pure numbers would seem to indicate.

ProjectC55

Do I hear a watchout E60 V10 M5?

PS it would be nice if there was rm to twin turbo the low compression V6 in your car! Now that would be a monster. Would be able to hurt the CL and SL65 in the 1/4 mile and perhaps even farther to a point!

KompressorKev

haha i was just kidding. i would love to do that but as usual i don't have the funds to. the nice thing about the c32 motor is the compression is 9:1 and has some forged internals, definitely set up for FI. i think without going turbo, off pure speculation, the supercharged c32 motor could make 500hp i would like to think. people are already putting out circa 450hp/450trq with easy stage II bolt-ons, head work and valves, custom intake manifold/throttle body and some cooling mods could be deadly! realistically, with pulley/ecu, i'd love to trap around 110mph, maybe slightly higher if i get likely.

i read somewhere that the C32 pistons are cast and not forged. can anybody sehd some light on this?

TopGun32

I just saw the AMG Speed Channel special..

They drove practically all the AMG cars except the C class, ML and G.

The driver Tommy Kendall drove a race ready CLK63 with paddle shifters. The car was bright orange and he raved about the direction of AMG.

I feel that the 55k engine is great for immediate thrust and awsome torque, but its down fall is heat and top end.

The 63 will loose a bit on the thrust at lower speeds, but will not suffer from heat soak and will gain top end due to the 7spd trans.

Either way, I will end up buying an E55 and wait a few years until I can afford a E63 or CLS63.

ClayJ

I'm pretty sure that they are cast.....

MKB had forged's made for their SHO C32 mod package, if I remember right.

AMG_55

the new engines have 4 valves per cylinder not 3 like the current ones

KompressorKev

not sure, i just remember reading it from road and track early on:

"The forged crankshaft and pistons, the connecting rods, the hollow camshafts (one per bank), the valve springs, the oil pump, the balance shaft and, of course, the engine-management system are all new to ensure reliability and higher performance."

im so happy my lease runs out in october

PC Valkyrie

The current 5.4L V8 in our C55 is based on the old 3 valve per cylinder 5.0L V8 from Mercedes Benz. Of course, AMG did its typical bore out job and heavily modified it to transform it into the beast we have in the C55, CLK55, and SLK55.

The new 5.5L V8 from Mercedes Benz is a brand new design with 4 valves per cylinder and variable valve timing. This new engine is going to make its debut in the new generation S class. In time, every "500" series car (CLK, CLS, E, S, ML, R, G, etc) will get the new 5.5L V8 which makes 382HP in North American trim.

This new 5.5L V8 makes more peak HP and peak torque than our beloved
AMG 5.4L V8.

ProjectC55

It's such a sin! Compared to...... Because it will still destroy most cars on the hwy!

P.S. The SLR enjoys the same motor

I also posted this many times many months ago.

The real impact is really for those got the 2005's SOHC 306hp on SL500 and the new ML500, R500. At least, I got the offical news that 2006 SL500 will get the DOHC 388hp but not sure about what M500 and R500 will get in 2006?

A good guess, yes, the DOHC 388hp will later go to the 'higher-end' models E, CLS, CLK. If the 388hp CLK500 priced same as the current model, it will be 20% cheaper than C55 and 40% cheaper than CLK55 in my country.

(Yes, we all know, CLK500 is not a AMG, and no standard Benz can replace a AMG. So, I hope no one is trying to argu on this )

C55 is still a 'unique' case, in a view point assuming that , there will be no 388hp C500 W203 to compete with it (historically there is no C500) and W203 is outgoing anyway. However, current model CLK is still at its mid age of generation and it is still 'luxury'; so it is logical to assume CLK will get the 388hp treat.

Now, who will buy a CLK55 with less power than the CLK500 and 40% cheaper (in my country)? This brings up an interesting point. Yes, the answer is , by all good guesses, the 2007 CLK W209 AMG will get the 6.3 litre 420-450hp AMG DOHC powerplant or a sushi treat of 6.3 litre 500hp BiTurbo just like what the E63 AMG will get next year. It comes with a 7G of course. :p

The CLK500, CLK63 will hit C55. I am keeping my C55 for another 3 years anyway.

TopGun32

this year will be the year for AMG...

it will counter punch all the jabs from BMW M and Audi RS...

first with the ML63, S63, CLK63, E63, CLS63 and we hope C63!!

FrankW

I'll be happy with W211 E550...LOL

ProjectC55

There is no 500hp bi turbo 6.3L. N/A the 6.3L will make 500hp.

cntlaw

Good catch
Another good guess is CLK63 gets a detuned 6.3 litre , say 420hp. This makes sense as it seems SL, E and CLS always get the more powerful AMG engine. If the CLK/C gets 420hp, that will be another performance war with M3 E90's 420hp V8 and the RS4's. We will see Improvize coming back soon. :p

ProjectC55

Folks will also figure out how to free up the engine in the CLK63 to produce the same 500 hp as in the other AMG's.Mark my wrd!

cntlaw

actually.....i really dont mind to take a CLS550 (40% cheaper than CLS55 here) , CLS550 probably does better than S550's 5.4s.

derrick_lui

so........time to sell our C55's?

I wouldn't be happy when a CLK550 points a finger at me and says "look its an AMG...but im faster!"

TopGun32

The E550 will be a heavier car... so performance would be about equal..

The E will have more power and 7 speeds, and the C55 will have less power and less weight..

I say, if you plan to stay with the C55, pulleys, headers and ECU will become a necessary mod...

I say the new E550 will hit low 5's and perhaps a few 4.9's and 1/4 13.2 to 13.4.... trap speed however could be better due to shorter gearing..

Capt Nemo o2

Hmm, I would have thought that the CLK would get the 4.6L 32V V8 with 335 HP, as would the ML until they each get completely redone. Its the base engine in the new GL.

TopGun32

the BMW 650i will have 360hp, therefore it won't be a benefit for MB to place the smaller engine on the CLK.

The 4.6 could be offered in othe models such as the ML, R as an entry level v8.

The GL needs the 5.5 engine to compete against the Escalade.

Capt Nemo o2

I dont know, I see the 6 series more of a competitor to the SL. The 3 series convertibles are more of a match for the CLK.

As far as the GL, I would have put in the 5.5, but MB decided on the GL450 instead.
