not surprised at those ****s going away with manuals. The S4 already don't come in manuals and i don't even know if Benz even makes a single model with a manual. The Volvo Polestars are also auto and don't believe have any plans for a manual. Alfa scratched the manual on the Giulia and the list goes on.

And importing a car is hard as **** unless it's like 15+ yrs old.

Approving a component for serial production is more than just beating on it a few times with a hammer.
If you were familiar with the car and others like it built by a highly respected member/members of this forum you would know that is just not just "one dyno run". There are several built on this forum in a small shop/business that are pushing 800-1000 and run like champs. Hell, they drive (not always trailered) all over the country for certain racing events. If they can do it, BMW could.

But at any rate, the post was in jest due to BMW's claims of max hp on manuals.

Yeah but you have to consider the quantity of transmissions. Having your goal as 6 sigma compliance to the spec makes for a really overbuilt transmission on average but the worst one still has to meet the requirement.

Hydraulics are part of the transmission system right? Rod bearings are part of the engine right?

Come on dude.

None of this has anything to do with the ability of a manual to handle the power output of the engine but instead has everything to do with the fact that the vast majority of Americans don't want a manual.

I hear you but if you think that if everyone boosted their engines to quintuple the power output the transmissions would have the same failure rate, that's delusional. You'd see a lot more widespread failures for sure. Glad those people are getting luck with their units but they are on borrowed time.

i have never seen data that shows what % of the market wants manuals and how it's changed overtime, but my understanding is that it's expensive to have manuals certified (probably not using the right word here) and be able to sell them so companies are just foregoing those costs.

What is the reason for so many short lived clutches on the E39 M5 then? that was a serious problem area, was it the flywheel weight/design? what?

Because that car is only 400HP and from what I understand, it shredded clutches for a living on a daily basis.

The certification cost is peanuts compared to the design effort, supply chain, sourcing, inventory, manufacturing process, testing, reliability, etc related to maintaining two different transmissions for a given product. Every one of those things effectively doubles the cost and if you can't amortize it across a high number of units sold...well that adds up pretty fast.

Oh I get it...... definitely not delusional. These guys building these high hp cars have money to do such and are fully aware it's not going to last 100K miles. Much like the guys that can afford to buy the new M5 at 600 something HP, you think they are going to keep them past warranty or over 100k.

The transmission issue had nothing to do with the torque going through it. That's the point.

It was just undersized I believe. Plenty of good aftermarket clutches had no such weakness.

Hello I am 20-something and have read plenty of articles and introductory textbooks pertaining to this matter. I've also passed many multiple-choice exams in my time. I am thus highly qualified to guide your perspective on this highly technical and strategic issue.

The hydraulics are part of the transmission so if they fail, the trans fails. The torque going through it has nothing to do with the sh1tty reliability but the transmissions as a whole were less than stellar in reliability.

But that's not the point. We're talking about manuals not being able to take the power. That Getrag transmission was more than strong enough. The hydraulics have zero to do with the transmission's strength and durability in regards to the topic at hand.

You're being difficult on purpose.
