LIKES

This gearbox is one of the most compact sequential gearboxes. It has in fact a 2 speed gearbox combined to a 4 speed gearbox. So there are 8 gears, but it's more compact.
Thanks to this conception, the gearbox itself is more compact, and the shift system, using the rotary changeover catches of the Bugatti Chiron is also pretty compact.

How does it work exactly?
When the changeover catch of the 4 speed gearbox makes one turn, it activates the one of the 2 speed gearbox. So to change the speeds from the lowest ratio to the highest, the 4 speed gearbox does 1; 2; 3; 4 while the 2 speed gearbox is in first gear; then the 4 speed gearbox activates the second speed of the 2 speed gearbox, and it does 1; 2; 3; 4 again.
