I am not one to spread rumors... however a source that I have spoken to before and that has always been right has told me that the SL63 will be here much sooner than anticpated... maybe by the end of the year. He also swears the car will be turbo, giving the SL the most power of the 63 series.

Dont know if its BS, but it sure sounds good.

SL BRABUS

wow.....If it is come true......it will pump out anywhere around 600 to 700 HP.........

For new productions, AMG will limit its engine models into two: 6.3L n/a and 6.0 biturbo. If SL63 is rumored to have turbocharger, then it must be the 6.0 biturbo. So I'm curious how is it gonna be any different performance-wise than the current SL65? Maybe they'll upgrade the whole headers/exhaust system? air intake?

amgme

is this 63 turbo limited to only sl and s classes? how about the e class?

360_iti

E63 has the 6.3L n/a version, the same goes for CLK, CLS, R, ML. Most likely the 6.0 biturbo will be for S, SL and CL only. But I'm not sure.

I don't see this happening. The new V8 is going to be n/a in everything for a few years.

Wouldnt make sense not to turbo the SL since its considered to be their flagship model. Having the same motor in the SL as the other 63 models doesnt make it stand above them.

360_iti

That's what I believe too.. the new V8 isn't due for steroids yet.
It's interesting to see what AMG is planning to do with their SL series. I have a feeling that SL63 is replacing SL55, just like the CLK, CLS and E class.. so the 6.3L n/a will be replacing 5.5L kompressor. In the meantime the SL65 will still be there with its 6.0 biturbo.

I said this before: It is unlikely the SL will keep the 55 badge much longer due to the trend in lower priced models.

The R230 SL was just "facelifted" and will likely not see any engine or transmission changes (55 or 65) until a new SL is released.

I'm of the understanding that MB is currently developing two new high HP FI engines which may find their way into the R230. However, neither is a turbo charged version of the 6.3L, rather the new N/A 5.5L that's powering the 550's. I beleive I read that both SL69 and SL73 are trademarked by MB.

The SL63 is definitely NOT going to be turbo, at least until the new body style comes out. You're looking at 515-520 ponies out of the V8 and that's about it people.

I've heard we got another 3 years or so with the current R230 SL. I seriously doubt that they would go with the new 63 engine (especially a turbocharged version) on the same current R230. On top of this, they just upgraded the SL55 to have over 500hp and they updated the exterior and interior of the SL. IMO we will see an SL63 in about 3 years (hopefully turbocharged). I also don't see why the new CL63 would be n/a 6.2 V8 while an SL63 would be turbo. When the turbo 63 engine comes out, I think we'll see it in both the CL and SL and probably S, just like the most powerful 5.5 Kompressors were on the SL, CL, and S.

But if you're right, then an SL63 Turbo would blow the new M6 (and pretty much everything else) right out of the water...in acceleration of course.

NdnMbLova

all i can say is, the 65 engine is here to stay for a while

Germancar1

Yeah there is no SL63 Turbo coming until about 2010 or whenever the SL model is totally redesigned which could be 2010 or longer since the SL tends to run a little longer than the typical 7 year cycle MB has now. The SL I would imagine isn't an easy car to redesign like the CL/S-Classes so it is going to be a while I think. No way the SL63 is going to keep the "SL55" badge either, thats silly.

This is the same thing as before, the S-Class/CL came out for 2000 and then for 2003 the S/CL got a facelift and a new SL also came along for 2003 and they ALL got the new turbo V12 and Supercharged AMG V8, same thing will happen this time around. When the S-Class gets a facelift for model year 2010, their will be a new SL that year also, and they'll all get the turbo 6.2L V8 and a brand new V12 for the "600" models. The 6L V12 in the "65" models might die at that time if the turbo V8 approaches 600hp which according to various sources it will at 571hp and 707 hp for a all-out turbo version, but the 707hp version is for the sports car AMG is supposedly coming up with to replace the SLR.

If Mercedes was going to do a SL63 they wouldn't have spent the money and effort on the old 55 engine in the 07' SL55, they would have just dropped in the same 525hp version of the new AMG V8 that the S63 and CL63 are getting, to be shown at the end of this month in Paris. Then again who knows maybe the 08' SL will be a SL63 with 525hp and much less torque, but that would be a mistake IMO. Either way ain't no turbos coming until 2010.

the current issue of Angelino magazine (an LA lifestyle magazine) has an ad in the current issue from Beverly Hills MBZ showing both a 2007 sl55 and a 2007 sl63.

now the picture of the sl63 looks like a sl65 so i'm wondering if its a typo or saying there will be an 07 sl63.

sprins

Typo.

If NdnMbLova is right, which I think he might be, the (new 2010+ model) SL will be in 63 and 65 flavours.

I think he's right because the AMG development of the 6.0 turbo verison of the new 6,2 (63) engine was cancelled some months ago as was confirmed by some well informed people (like Wolfgang and others).

I emphasized well informed as people here tend to take words from e.g. MBUSA 'sales/marketing manager' Rob Allan for 100% truth whereas he just seems to talk/spread rumours like the next guy.

I’ve seen recent interviews with Volker Mornhinweg, the new head of AMG, in Edmunds, one of the British magazines – I think it was Car – and one other place I can’t recall. He was pretty forthcoming and spoke about turbo V8s representing the ‘intermediate term’ future for AMG, implying that the engine isn’t ready yet. He mentioned two versions with about 550 and about 700 HP. He seemed careful not to say that the turbo V8 was based on the 63, and his comment that it will have direct injection makes me think that it’s not.

In one interview he said a twin-clutch direct-shift gearbox was being developed and will be offered in multiple AMG models.

I go along with the theory that the turbo V8 and new gearbox will show up when the R230’s replacement does.

AMG 17GT

I agree silly Imo the 55's exposed the need for more tractible power and the trend is now toward transfer of power to the asphault, and not just brute torque.

//AMG55lover

The '63' engine with TT is canceled and they have given the engine in the S 63 and CL 63 525 HP. They keep on producing the SL 55 with the supercharger until the new model line!

rdk

2007 will be the final model year for the SL55. It will be replaced in 08 by the SL63 with the N/A 525hp 6.3.

//AMG55lover

I don't think so, otherwise they did it already, together with the facelift!

What my dealer told me was the current SL55 will go on sale for the next 2 years or so. Same applies to the G55.

Re New SL, the 129 went through 3 changes in its 12 year life. the R230 has only been around since early 2002 with one change

I think that the new CGI engine (stratified charged gasoline) will be fitted at some stage to the SL. this engine churns out 350nw at 2400rpm, at 75mph it is only turning at 2200 rpm, it does not use much gas. No doubt that AMG have got one, we will see what happens.

I doubt it will be turbo.

I have the 63 in an ML, and it delivers a much more consistant acceleration then the 55 COMP. Drop that 63 motor in a little car like the SL and that car is going to be QUICK regardless. I cant wait to get one.

My dealer said the SL will not be out until the end of 08 (09 model).
