I ahve a fairly decent idea of how an F-1 Sequential gearbox works but i would like to know how the clutch works. I'm pretty sure it is electronic but how long does it disengage for? Does the engine cut ignition while the clutch is disengaged? Why doesn't the car jerk when the clutch re-engages (maybe it does but clearly not enough to shake the rear tires loose)?

any information would be greatly apreciated. i did some searches but didnt find the info i was looking for.
