Because they flat out said they didn’t build routing for the linkage into the chassis

Martinjlm sounds pretty certain, that's the best info I've got on it so far...

Porsche got back with the driving experience program and I believe you’ll see a 7 speed transaxle like this one in the C8.

We’ll see. Some folks in the know seem to think otherwise. It’s a road race car that will benefit from a manual trans.

I got a chuckle out of that. Why? From the article.... “In November 2017, Corvette Forum discovered a leaked document from auto industry analysts IHS Markit that broke down coming engine options for the Corvette and a Cadillac. ”

I’m an industry analyst at IHS Markit. I wasn’t there when that info was leaked, but I have, since I’ve been there, corrected the information that was there when I got there.

Anyway, I am not certain what in that article drops hints about an MT. There is theoretical speculation based on a patent for a “virtual, shift by wire” manual, but that is pure speculation at best.

Different companies, different vehicles, different architectures. Porsche took the MT out of an existing platform that had been using MT for years. Putting it back in was really simple.

GM designed a vehicle with the intent that it would never need nor accommodate an MT. Deciding after the fact to put one in is non-trivial.

Quoted again, just because....

Executive chief engineer Tadge Juechter told Car and Driver that part of the reason is the desire to not breach the mid-engine C8's central tunnel: "That tunnel is the backbone of the car, and if you break the backbone, you lose a lot of structural efficiency. With a shifter, you have to have a big hole in the tunnel for the linkage to go through."

Why do think a manual trans needs a linkage? Electrical actuation is common place and greatly simplifies a manual trans.

It’s not just me. It’s the guy who is totally responsible for the car that mentions the need for the linkage. But there would definitely need to be a physical linkage between the clutch pedal and the clutch, which in this instance would be behind the driver, not in front of the driver. Meaning the clutch linkage would have to pass through the tunnel. The patent I mentioned is for a virtual connection between the clutch pedal and the clutch. Combine that with a virtual shifter, which is already available for automatics and DCTs and you have a path to get there. All you’re really doing though is adding a pretend foot movement to the same technology that enables paddle shifters.

Passing the mic back to Mr. Juechter.

This is basically a DCT. You get to push a peddle but it’s no longer true engagement, you just Feel like it is.

Only ruling out a hard shift rod might not make a MT a complete impossibility.

If the demand is there for a MT then Corvette will put one in at some point, whether it makes sense or not. Just like spoilers on front wheel drive cars. I hope for a true MT on that Corvette, but I think the days of MT cars are almost over. I think we're heading for this:

Cars haven’t had clutch linkages for decades..... a 14” diameter hose connects the clutch master cylinder mounted to pedal to a slave cylinder at the clutch.

Clutch isn’t the routing issue, it’s the shifter.

Chevrolet will build it if there’s demand.

Also valves control the rate of clutch engagement, which was a launch issue for Gen5. But it feels like you are more involved than you are.

Also what demand? The reason there IS NO manual was lack of demand.
