Anyone know when MB will be introducing the 9speed tranny in the e63s?

thanks

i havent heard anything, if i had to guess i dont think they will do that until the body change, as they just refreshed the E class

ManhattanSpin

I would guess in 3 years they do the major changes

looks like MY 2015.

never saw this, but after reading it said Europe gets it first in the E, then for the CLS over in europe. I havent heard anything for the AMG's, i dont think they will be putting a 9 speed in the AMG, this will probably be for the 550

I would expect the next generation of E63 to receive a DCT rather than a 9 speed autobox.

Having a DCT would also mean the end to those interested in tuning since a DCT would not be able to handle anything higher than the upper 500's lb-ft of twisting force. DCT is a plus to lighter cars but a negative to heavier cars like the E.

HPMan

I disagree. Just look at the GTR scene and there are many examples of DCTs handling well in excess of 600 lb-ft of torque.

otakki

True, but at the expense of reliability to the DCT units when exposed to that level of torque. I only go for oem tune and I don't plan on keeping these types of cars outside of warranty so I'm not worrying about it. As a result, I also wish for a DCT on the next model change.

all 2015 US Model eclass to get the 9 speed tranny.

It can handle 1000 Nm of torque....

Likewise, the MCT is able to handle a lot since it is based on the same transmission but with a clutch pack.

I guess car transmission is like bicycle with more and more rear cogs added over the years and the whole thing eventually looking like a pine cone.

HPMan

There is little to no chance that an E350 will have the same tranny as an E63. From where did you receive such intelligence?

impex4

the e350 and e63 have the same transmission except
the e350 uses a torque converter and the e63 uses 2 clutch packs instead

Not sure it will get the same transmission or not, but the 9g-tronic is rated to handle 738 ft/lbs of torque. Exactly the same output as the 6.0 V12 biturbo. Coincidence? My spidey sense says probably not. It seems to have been designed with AMG in mind. They'll probably call it the 9g-tronic speedshift or something like that as they did with the 5 speed and the original 7g-tronic.

HPMan

Hmmm, I didn't know that. As long as they speed up shift times, I suppose a 9 speed autobox would be ok. I still think DCT would be the better route for AMG.

benyl

More of the same. Slow shifting. Who cares if it has 5,7 or 9 speeds. It isn't like AMG owners care about fuel economy. We just want fast shifts.

I would rather have a 6-speeds and DCT shift speeds than 10 speed that gets me 5% better economy.

Get me the 6 speed or 8 speed ZF and forget the MCT / DCT bull****.

There goes the resale on 14's if there will b a 9speed In the 15

HPMan

I disagree. More gears is not necessarily better. Given the torque curve of the E63, I don't think I would want 9 gears.

dr. ss

What us performance guys know and what the market does are two entirely diff things

Unless case is identical, I'd be surprised of they'd put 9G in end of cycle car. Certainly without it being in other AMG's too that are younger in cycle, or just MB's, new S, new C, mainline C. Plus it seems they're throttling M157 back some, so blowing 7G vs. 9G on street just requires bigger dustpan.
Maybe A727 would fit?
