Just imagine if it was a 10spd DCT, you could downshift like 9 times coming to a red light!
The ultra quick up/down shifts are quite entertaining in high revving motors

I did some more digging around on the deep web (check my new sub-handle) and found out more details of the new DCT. Images to follow.

Nah, with anything more than 7 speeds, the transmission becomes a purely auto only experience IMO. Can you imagine braking at the end of a long straight and downshifting 6-7 times? That's not something you want to be thinking about on track, rather it is would become an auto only transmission on track, in which case you would hope the transmission logic is smart enough i.e like Porsches PDK, though that hasn't been beaten yet for track intuition.

lmao go to a drag strip and you got 2 shifts knocked off before you hit your 60 foot :lol:
F1 cars gears are spaced out a lot farther than a road cars though, because they reach much higher speeds and can accelerate much faster, obviously
A 10 speed in a GT350 means you'd be shifting on average ever 20-21mph assuming the car could reach 186 mph (300kph)... that is way too much lol
Nice first post. Welcome to M6G

I thought extra gears on non-race cars were for economy not performance and DCTs are for faster Auto shifting transmissions.
On a track isn't there a case for too many gears?

Would you be so kind to actually provide the link R&T referenced here? I'm starting to think my tinfoil hat is preventing me from finding it. :shrug:Nice first post. Welcome to M6G
Your guess is as good as mine!

Yes sir you got it. Porsche had actually stated that the gearing in their PDK is actually longer than you would typically find in a DCT gearbox (relative to the cars power level) as they tested and found that the longer gearing resulted in faster acceleration. Even with a very fast shifting auto or DCT, every time the gears change, you lose time. Does the difference by adding gears improve acceleration enough to compensate for that? Who knows, but Porsche has said it actually works against it.
Definitely can be too many gears on track IMO. You want a very fast shifting gearbox, with 6-7 speeds tops. If it were advantageous to have more gears, Porsche, Ferrari, McLaren etc would have them in their cars. 7 speed DCT seems to be optimal for 6 drive gears with a single overdrive for fuel economy.
GM and Ford can wax all they want about how "fast" this new A10 is, but the reality is the last 3-4 gears are almost certainly overdrive for better fuel economy. And while they claim them to be "faster" than a PDK, it was a measurement taken from a single upshift during a 2-3 gear change. The autos paddle response is still far slower than a proper DCT in which the transmission changes gear instantly the monent you touch the paddles.
