"The five-speed has a torque capacity of 796 lb-ft, while Mercedes' new seven-speed can only handle 542 lb-ft."

I hope they are working on a stronger 7-speed.

 

Lots of praises. Sounds very promising.

 

I want that CLK DTM.

 

WOW....SLK63 will be very scary

 

Am drooling in anticipation of E63 wagon -- please, MBNA, please!

Hey, it could happen...

 

Lemme ask you guys and be honest. With that motor (lower torque, but higher hp) BUT, 7 speed gear box and perhaps a little more stought rear end ratio.....you think we could still eek out mid to upper 12 sec 1/4's, or are we destined to be bumped back into the low to mid 13 range. I think if they get the right combo...we could be close?

 

No worries....Anything new AMG gives us want touch our K2 car for a long time.

 

Interesting article-based on preliminary data, the E63 is actually making MORE hp from approx 5000rpm up to the new peak hp of 6800. If they gear the new E's properly, right out of the gate. the new E63 has a chance to be quicker thru the 1/4mi. than the present model.

I'm thinking :

1st gear - approx 40mph at redline
2nd gear - approx 62mph at redline
3rd gear - approx 93mph at redline
4th gear - approx 125+mph at redline

Based on this hopeful example, the engine will be making a "MINIMUM" of
425 hp after each gear change climbing to the redline and the next gear. (These figures based on the HP/TQ graph supplied) Presently in our E55's the HP figure is in the 350-375 range at the 1-2 shift as well as the 2-3 shift. Hence the new E63 has some promise if geared properly!!
Any gearheads out there who will critique my archaic reasoning here??

 

I think in the long run, the E55 will be the more desireable. With enough torque, the gearing deficit can be overcome. Plus, its nice to know our E55 powertrain can handle 738ft/lbs of torque.

 

I hate to disappoint and stop anyone before they go modding crazy but the E55 5 speed transmission is not "exactly" the same as the ones found in the 65 cars, those cars have much stronger derivatives of this transmission and can handle the full 796lbft or so.

The engine should not disappoint IF geared correctly, but then this is another hurdle altogether. AMG have not made custom gear ratios, they simply modify the control logic, strength and the final drive. All AMG cars as far as I'm aware use the same ratios of the 5 speeder with varying degrees of strength and differing final drives with the exception of the SLK55. If this new V8 will use the same ratios as the SLK55 we may not have much progress over the current E55. The video review did say its not exactly a revver but builds power smoothly, mostly due to the displacement or possibly due to longer ratios which is definitely not a good thing as far as acceleration peformance is concerned

 

At peak rpms,the supercharger consumes almost 100hp in the 55 engine.
55K will have initial torque advantage at the take off but at speed and at higher rpms,the new 6.3 should dust the old one.

 

no cls??? so does anyone still think theyre doing a tt in this? and the c sounds interesting with a few hundred pounds lighter than the e. i got really pissed off at my car yesterday and am seriously thinking of putting it on ebay and just starting over.

 

Yup, it's already in testing, rumors of course, but more than one source.

It will be a special edition like the CL, SL and S65, but she's coming.

 

What we really need to keep up is an aftermarket twin-turbo setup for our E55.

 

Torque wins races, i'm sticking with my blower.

 

This article is not the gospel...notice the sl isn’t on the list either. Don’t forget that the 4-valve n/a 63 is to replace the s/c 55 and deliver similar performance for all kinds of benefits to MB. A c-class probably will not be on the list unless the marketing strategy changes.

A tt 63 is not that much of a stretch. It could replace the 3-valve 12 cylinder tt 65 and also be programmed to be stronger than the slr setup.

 

I am not an engineer, but just a simple minded person looking at the figures-to me the 6.3L NA engine is a detuned engine, vs. the E55 SC engine-despite all the fancy engineering and coated cylinder walls etc. I bet there will definitely be a boosted version in 5-7 years: just like what happened with the 5.5L in the E class. With Daimler Chrysler so hungry for profits, the cycle may even be shorter. What has been disappointing about this corporate strategy of profiteering is to sacrafice exclusivity. The cool factor was definitely much higher with the old W210 E55 when an AMG 5.5L actually was rare and mean something. Now, its in EVERYTHING!! I just hope that the brass at Daimler Chrysler will not go too much overboard and turn Japanese-short life cycles for the cars and deliver products with +++mass market appeal. A Mercedes product was never meant to be like that, at least not in the past. However, I do not hold out much hope, just look at the range of stuff coming out:

IWC CLS55-C'mon, its the "Eddie Bauer Lincoln" route

Maybach-Gangster chic:"hey look at me, lots of coins but no taste"

R class-nice car, but a Pacifica is much cheaper

SMART-who is the genius who decide to import that to NorthAmerica, land of the 4 lane cruzin bolouvards.

what about sensible products like the V class or the A class (I think that may be coming), or more CDi diesel products?? Or a real E class convertible? (I had a W124 cab and that is the best MB product I've ever owned)

Sorry about the rant.......

 

............I wanted to bring up a point I did in another post. The compression ratio of the 6.3L Na engine is 11.3:1. With such high compression, forced induction will be hazardous. In other to differenciate an SL63 from a C63, I doubt that MB is going to place the exact same engine in both cars and cause the C63 to be faster than the SL63. One year ago, I would have said that the SL63 will have its compression lowered and s/c or turbocharger addded, but now I hear that MB is giving up the entire forced induction business all together. So we shall see.

I don't think MB will give up Forced induction altogether. The twin-turbo V12 engines are the strongest in the world, any N/A attempt to replace their power outputs would require 8.0L or more displacement, in addition there is nothing wrong with them at all, they consume less fuel than their AMG V8K counterparts and are fully compliant with future emissions legislation. Moving away form supercharging I can understand for obvious reasons.

I do not see how this engine will ever make it into a C/CLK/SLK. For one thing the exclusivity appeal would go right out of the window. Secondly, even if a detuned version were to appear in the aforementioned cars, there would be no replacing the immense/adequate torque output. I suppose a torque limiter could be used but that's really stretching my imagination.

This engine produces around 80/81 hp per litre. If AMG were to implement this technology and self-produce a engine of similar mechanics and say 5.5-6.0L of displacement, you are still getting a 445hp - 485hp engine which is plenty for the next 5 years or so for the entry/mid range AMG's.

The only reason for the changing state of cars at such rapid pace is to keep up with market demand. Mercedes wants to captalise on every market segment, create new ones that never existed before (R-Class/CLS-Class) and be the number one in each. You cannot do all of these without continuously offering the best and up-to-date choice possible. FYI The SL's lifespan has been increased to 2012 (from 2010), the subtle facelift of 2006 will be the last major change (although this could easily change) and there are rumours of ending the F1-nose design era, the SLK/SLR were the last to have such designs. All in all, its is great for consumers to have so much choice nowadays than the 10-15 year lifespans of old Mercs. Rest assured, the products offered now (A/B/CLS/SLK/new S/ML are probably the best built Mercs of the past decade or so. The only down side is having to buy the best and newest now only to be outdated by the subsequent secret facelift which is unvelied 6 months later.

 

The one thing about that article that shed some light on a question I had with regards to the 7 speed trans. I had assumed that they would introduce a strengthened version of the trans with the next AMG engine released. However, the article made it sound like the designers of the 6.3 engine were limited in the amount of torque to suit the trans in it's present form. But, what about the brand new S 600? Does that fall under the torque celiling of the present trans, or will there be a new version to deal with that?

 

That sounds like good news to us 5.5 supercharged guys pushing out 550+ hp. That means that the 6.3 engines cannot be supercharged because the tranny's can't handle the torque.

 

600 will continue with 5 speed

 

The 6.3 will not hold a candle to the potential of the current 55K setup, sorry. I don't even want to talk about what it would take with the 6.3 to duplicate someone like DerekFSU's times. Remember, all he has is headers, chip, pulley, intake, cooling, and a small NOS shot. It's really VERY little but he makes INSANE power. His trap speed is only a few clicks off what the Carrera GT, McLaren F1, etc run. That is SERIOUS power.

Following with what Bilal was stating, I believe this motor is more accetpable for the cars currently bearing non-supercharged V8s. I think it's suicide to offer a C63 with the same motor as the S63...

Here's to hoping we see a blown or TTd version of the 6.3

 

I think that all of the drag-racing people on this forum will be very disappointed. Mercedes doesn't seem to want the 55/63 models to do that anymore, and I agree with them. This engine seems like it would be very good for the track, which is exactly what Mercedes needs right now. No car company can compete while still offering sub-par handling relative to competitors, and I feel that this engine is one of the parts to shifting Benz's focus more to performance/track vehicles. Perhaps everyone here will have to buy 65s now...
