See 113 and 116. The mounts and this link oppose forces caused by accelerating the mass (G loads) on a horizontal plane on the longitudinal axis. The link handles excessive loads including frontal impact also on one plane. See video for the functioning of the 4 MR mounts. Ignore SKANKS comments. The Ferrari's gearbox mount also takes vertical loads. .

I'm glad you didn't flunk your class. Congratulations !

While I suppose it could do that, I'm not buying it.

The entire powertrain for the 918 Spyder hangs from the car's carbon structure. There are no mounts underneath it, at all. ZF co-developed the PDK with Porsche. To date, the only non-Porsche car they've used it in is the new Continental GT, which shares the VW MSB platform with the new Porsche Panamera. They're keeping it in the family, so to speak. This particular variant, was developed specifically for Porsche's ultimate flagship. The mounting system in particular is unique to the 918. I am extremely skeptical that this tightly held piece of high end engineering is suddenly going to show up, nearly unchanged, in a GM product. I could almost buy it if it only had two traditional powertrain mounts under the engine block. The 458/488 uses that arrangement. Two under the engine, one on top of the transaxle. But four under the powertrain, with a fifth on top? That's extremely odd. It's also notable that the Tremec model doesn't seem to have that fifth mount.

So not only is GM is going to get this unicorn transmission that nobody outside of the VW family has previously had access to, but they're then going use that very unique Porsche mounting system for a completely different purpose?

Something about this just doesn't smell right.

1. There is nothing inherent to the ME design that requires a massive price increase.
2. The C8's cargo space will be superior to that of the C7.

There's no need for a FE Corvette now since the Camaro has already slid into the market segment previously inhabited by earlier generation Corvettes with models like the 2SS 1LE and the ZL1. We'll soon see a greater emphasis on the Camaro, with a new generation that embodies some of the classic FE Corvette character.

Say members, how do you suggest I respond to this post? Why is he talking about a P918? Should I be rude. Should I be kind? Am I missing something?
What's this got to do with a C8? Is he acting stupid. Is he stupid? I don't know what to do.. Help. Help me.

Of course it will because the C8 will actually be Dr. Who's new TARDIS!

From Wikipedia "while the exterior is of limited size, the TARDIS is much "bigger on the inside," containing an apparently infinite number of rooms, corridors and storage spaces within".

Now that we've established that the same ZF DCT/Transaxle that's shown on the Zerv leaked CAD views in Post #97 and Post #120 is indeed the same unit that's on the Porsche 918. I have also verified that with a member of the Porsche 918 development team( I can PM his information to anyone if needed). I discussed this DCT at length with him and he verified that the 918 engine and DCT/Transaxle was hung on 3 locations of the tub. The round mount on top of the ZF DCT is only a standard rubber composition mount. In fact all three mounts are only standard rubber composition mounts. The Zerv Leaked views clearly show four magnetorheological engine mounts under the C8 engine and DCT/Transaxle which is a far more advanced system than used on the 918. MR engine mounts control position of engine and vibration control far better than any traditional engine mounts. We discussed the possibility that ZF would develop that DCT with a new case design reconfigured eliminating that unnecessary DCT mount and adding two new locations under the DCT to match the MR mount locationss. He said that would be likely the best solution.

Ltomn, most likely the ZF's will only be on the DOHC engines and not the base engine which could have the manual transmission that's been purported. By the way Porsche has this ZF transmission replacement cost as $69,239.00. Look at the screen shots of the price lists.

I was under the impression that the C8 DCT will be built by Tremec (possibly under license from ZF).

So in a nutshell, there's a strong possibility that this CAD leak was a very, very early iteration. Coarse packaging geometry rather than fine grained production-intent math. That vertical mount not only is not a "longitudinal damper", but it's just a simple rubber powertrain mount. One that was meant specifically for the 918, and it'll be exorcised as ZF and GM adapt create a modified housing specific to the GM ME chassis.

I still find it odd that a direct competitor to the 911 will be the first vehicle outside the Porsche/VW family to get this transaxle, but that's a lot more believable than some of the other bullshit that's been posted around here.

I could be wrong but I think besides the 4+3 Doug Nash trans for the Corvette, the first six speed manual was in a '89 Corvette made by ZF of Germany. I think the first Porsche that had a six speed was the 993 of '94 but I could be wrong about the year.
