Seamless Shift Gearbox's

Hi devs I was wondering if in 2013 we could unlock a Seamless Shift Gear box like the one used in the McLAREN 570S and 12C for our super and hypercars. If you can’t I understand as their is definitely a lack of cars with this type of gearbox in cars but I believe that in the future it will be the standard for supercars and hypercars.

-UMG-

Those are called dual clutch sequential gearboxes and we already have those.

Note that each manufacturer that makes these things seems to call them different things (due to different languages) but they are all in essence the same.

Sequential gearbox’s are similar but different in a few ways.

Seamless shift gearbox’s have both the gear you were in and the gear you are shifting into when you shift creating a seamless shift. Sequential gearbox’s disengage the gear you were in and then ingage the the gear you would like to go into. Therefore sg’s and ssg’s are similar but are NOT the same.

You’ve just pointed out the difference between a single clutch and a dual clutch sequential gearbox…

well how come dual cluch gearbox’s are banned in f1 if a ssg is the exact same thing but it is used in f1?

Here UM just read this. formula1-dictionary.net/seamless_gearbox.html

But the ahort answer is a seamless gear box would be something like a +10 single clutch if you wanted to recreate in game. I doubt a double geared transmission, one where unlike a dual clutch with has an odd gear clutch and a even gear clutch, these have two gear boxes joined to common input and output shafts one for even and one for odd gears, will ever be made as they are literally only is in modern hypercars, f1, and moto gp bikes.

okay sorry for wasting forum space and your time

Well, it wasn’t a waste of time. I did get to read a good article on new different gearboxes. Which does make it seem like at least in F1, seamless shift isn’t dual clutch because dual clutch is disallowed.

I opened this, expected to see someone wanted cvts…thankfully i was wrong, cvts are the bane of transmissions lol.

While I do agree that they are very boring, CVTs do have some advantages on things like fuel economy and many of us hope to see them added soon.

But they are a bit more complicated than normal gearboxes.

Also consequent reliability and servicing (replacement) costs… As a concept they’re funky but there’s a good reason they never took off.

Well they are very popular in some applications.

Snowmobiles use those pretty much exclusively and they are very popular in more utilitarian quad bikes.

Although the CVTs used in those are a bit simpler than those used in cars. :smiley:

CVTs have taken off. The traditional automatic is slowly being squeezed out of the market by robotized manuals and CVTs due to cost and fuel efficiency.

This is something I don’t seem to be up to date on. Is it that automatics are changing, or are they being replaced wholesale by CVTs? I still see the term automatic being used almost exclusively to mean that, so I’m not sure what you mean, or where you’re seeing this.

Nissan and Subaru have more CVT than traditional automatics, Toyota has some mostly the Prius but the corolla has one as an option. They are making a strong showing but are not yet more numerious than the old slusjbox. Here’s the full list en.m.wikipedia.org/wiki/List_of … nsmissions

Audi has stopped using their CVT gearbox.

But GM is gearing up(lol pun) to phase in cvts to many of its small and medium cars.

The biggest issue with CVT, as far as I know, and apart from the dullness, is the limited range of ratios possible in a CVT-box. The modern 8 and 9 speed units are capable of doing a wider range of ratios, therefore being capable of delivering lower RPM during cruising and faster acceleration due to shorter gearing. Also, their capacity to transfer torque is limited, so the use in high-performance vehicles is limited. (Williams’ planned F1 CVT is wizardry :stuck_out_tongue:)

The Audi CVT had/has a range on the variator chain of 2.40 - 0.40.
It had an additional 1.109 reduction in the gearbox. So the ratio should be 2.66 - 0.44.
The 6 speed Tremec T-56 gearbox used in the Viper has a ratio of 2.66 in first gear, 0.50 i 6:th gear.

Torque was limited to max 400nm. (The Viper has well over 740nm)
