Was the system you worked on on the same theme as the C.F. Zeroshift?
So then these systems are robust enough for F1?
There are a number of ways to control shifts in a layshaft gearbox the C.F Zeroshift was not available at that time.
Shift systems designed for F1 do not have to be as 'robust'(last as long) as those for road use.
This makes it debatable as to the reliable use of some shift systems in road cars.
To be honest I do not know if the Zeroshift system you mention is.
I would expect them to have undertaken a lot of tests.
You should ask them.
The work I undertook on single layshaft stepped boxes did not end up in a road car because of this issue.
The twin clutch/twin shaft types are in road car use because they rely on their shift control in a different way that is far more reliable and robust.
Unfortunately this results in a much heavier and more complex unit with much higher torque loss and oil windage.
F1 layshaft gearboxes now have little in common with road manual gearboxes.
Interestingly, for electric traction neither type is reliable enough.
Tesla as an example had a three speed gearbox in the first prototypes.
It lasted 2,000 miles so they removed it.
I am waiting for the opertunity to meet the gearbox requirement for hybrid and full electric vehicles as soon as the market becomes mature enough.
At present there is nothing out there to do the job efficiently enough.
