Well, looks like we have confirmation of the SLK63 and it's coming next year. No word on power, but at least it's existence isn't a rumor anymore. This would be the fist mention of it on any documentation from Mercedes.

Ooooh...can't wait!

SLK55R

Thats from a long time ago actually and has been posted before on a forum. Don't remember if it was this one.

After that was released ... AMG was repeated questioned if the 6.3 would come to the SLK. They have said no repeatedly.

Of course if it does ... awesome!

You just had to go and rain on my parade....

I am sad also, but to get close to the rumoured 420-450hp on the 6.2litre engine I guess 55 owners need Valve Springs, cam's, headers and an ecu update.

or you can go for the 6.1 S Brabus upgrade for 445hp/

Acez

or kleemann supercharger for ~500-540hp

mbSLRwannabe

that was posted on the AMG owners forum a long long time ago, and was confirmed as bogus

Now that we have the hp numbers for the C63 AMG I'm betting that we'll see a SLK63 with the same 457hp or 450hp for the U.S. market SAE conversion.

I say 63 for the R172, this topic was debated before no space for the 6.2l V8.

silk32

any spy shots of the r172?

Ferri

I do not think that is entirely correct. The SLK and C (203) shared front ends with the current CLK, where the 6.3 was fitted with no problem. I believe the SLK will soon be endowed with the 6.2L V8, and get a black-series like styling makeover.

alroumi

Thank you for enlighting me, well we will see.

You are right on the money.

And for those who wants a little more power from the M113/M156, please contact EuroElites as EuroElites has now the capability of custom tuning (in house)

Cheers,

SLK 55 Kleemann

True!
My car delivers at the moment, 513 Hp and 700 Nm, and in August I will add Camshafts and ofcourse their Exhaustsystem -

The sad part is that C63 and SLK63 cost roughly the same, while C63 has 120hp more. Tell me if I'm crazy, but that does not sound fair to me

And with the new M3 coming out with 410hp, SLK55 needs to have 450hp minimum.

Do you have a dyno by any chance? How much hp at the wheels?

SLK55R

The SLK does NOT need 450 hp. Look at the weight differential with the C63. The reality is that at anything over 400hp at the wheel the biggest problem is traction already.

If the SLK does come with around 400hp RWHP stock they better make a serious changes to allow greater traction.

AdamG@NorCal

Don't worry, we can always beef her up to 450 hp , no problem....

mbSLRwannabe

if the SLK gets the 6.3 liter engine i'm sure MB would HAVE TO fit atleast 305+ rear tires for the traction.

Tuskir

Oh please... if C and CLK classes can handle it no problem, so can the SLK. The reality is that SLK is the only Mercedes AMG sports car not to recieve this upgraded engine... if C and CLK are getting it, so should the SLK. SLK is not getting any love from AMG


AdamG, its true you can upgrade it no problem... i just think that for $63,000 MSRP, it should have the 6.2L engine just like C63. Why should it get a lesser engine? That 5.5L V8 is like a decade old, c'mon...


P.S. I'm kinda tired of hearing the "6.2L engine was not meant for the SLK, it doesn't fit.. bla bla bla" R171 is an 2005 model, Mercedes should've thought about making the 6.2L engine fit during its development. Keep in mind that C and CLK bodies are much older, so there really isnt any excuse to be made here...

Tuskir

No they dont. CLK63 and C63 both have 255 rear tire. 265 would be more than adequate for the SLK63... which fits in the back no problem.

bfnnrgn

That's true, but they also weigh 3800-4000 lbs. The SLK is much much lighter.

Tuskir

300-400lbs lighter than CLK63 coupe is not a huge difference in weight really... with that 6.2L engine in place, the difference in weight would probably be even smaller.

Shinigami

I disagree, 300-400lb's is quite a lot of weight (10-15% lighter is a big deal in a car), and the 63 engine is lighter then the current 55.

ProjectC55

LOL! Ok you try bench pressing 300 to 400lbs and you tell me how light you feel it is. That's a BIG difference in weight especially ifthe cars are using the same motor and have the same HP more or less.

SLK 55 Kleemann

No its measured by Kleemann and its not at the wheels:
