"easier to integrate hybrid technology"
This is the reason for all of these 'by wire' systems.
The object is to eventually remove the driver. Having a system
that is easily controlled by computers is the first step.
So why do it with a manual? Why not just straight to auto? Like, y'know, all the hybrids already out there?This is the reason for all of these 'by wire' systems.

Couldnt they then create a car, with a dual clutch gearbox where you can either choose to operate gears Normally or flick a switch and set it into an auto mode ?
Done right that could provide the interaction everyone likes when they feel like it and a full on auto mode for when you are stuck in traffic ?
Cant see a technical reason why that couldnt happen, but its possibly a bit of a niche market ?

Like almost everything with flappy paddles?Oh, right. With a pedal that you can use if you want.
I cant see it ever happening but I reckon it could work with the right feedback, to be honest a hydraulic clutch these days, with the delay valves and whatever isnt the last word in feedback anyway so doing it electornically doesnt seem that different, the gear shifter could be engineered however you want if it doesnt actually have to move cogs around, could even stick some kind of vibrating thing into the shaft so it feels like a 350Z, to be fair, Nissan engineered that in traditionally so its not really that much more contrived doing it with electronics.
Hackers are going to have so much fun with all these electronic gizmos in modern cars.
I agree we are down at the lowest common denominator and cars take very little effort to drive but also have very little character left.
Even Nissan are trumpeting the single pedal for throttle and brake on the new Leaf, reminds me of a scalectrix controller.

I don't see this as much of a benefit to a driver, if you can't competently use a clutch and don't really want to then autos are available.
I suspect like EPAS and the earlier electro hydraulic steering systems this will have sizeable benefits on the production line. Less hydraulics to route, just two ready made assemblies, no need to bleed the system, it can test itself after assembly.
I am sure such a system could report clutch wear though, which would be handy for used buyers, and it might stop clutch riding twits from burning one out every 30k miles!

Good post...basically it will save production costs. There are some nice features that you can offer the customer too, but saving money/time is the real reason.I suspect like EPAS and the earlier electro hydraulic steering systems this will have sizeable benefits on the production line.

You've forgotten Honda IMA! Both the first insight and the CRZ pull off a regular clutch operated manual by providing the hybrid boost to the output shaft, rather than directly to driven wheels.Not a hybrid engineer, but I imagine it's not as efficient / beneficial (No instant torque as it's hooked to the engine) as a direct drive motor - Though it does give you a knob to play with

You may get the odd benefit like the one above if a car's been abused, but I suspect the average clutch life will drop significantly vs an old-fashioned manual...

Instead of designing every set of ratios to give ideal 0-60 times (who f
king cares) and to pass nonsensical emissions programs, give us a 1st gear that creeps at tickover at 3mph. and 2nd at 5mph, and 3rd at 10. Like my old cars used to do before this ridiculous economy gearing was introduced.

My 1.4 Will happily lurch slowly onwards at 4mph in 1st, and 6mph in 2nd

But in the article it talks about facilitating creeping in traffic...AKA riding the clutch. Which probably isn't that dissimilar to what automated manuals do now.

They've been doing it in heavy trucks for a while now.You may get the odd benefit like the one above if a car's been abused, but I suspect the average clutch life will drop significantly vs an old-fashioned manual...
General feedback seems to be the electrickery does save wear, as it makes fewer mistakes than a driver might.
Case in point for us Honda users - they'll creep forward without touching the throttle and feathering the clutch, but try that in reverse and they invariably stall.
