Modern cars have an engine and a gearbox. What if we have a second gearbox in the car?
How It Works
Paddleshifters will be required. The gears will go (from shortest gear to longest gear)
1:1 —> 1:2 —> 1:3 —> 1:4 —> 1:5 —> 1:6 —> 2:1 —> 2:2 —> 2:3 —> 2:4 —> 2:5 —> 2:6 —> 3:1 —> 3:2 —> 3:3 —> 3:4 —> 3:5 —> 3:6
Effectively you have 18 gears, even though you really have 9. I remember a while back Ford tried to make an 11-speed gearbox, but we can have upwards of 30 gears simply. It could also work for an automatic, and if a gear is not needed, you could skip the gear altogether.
99% of drivetrains follow a simple path of
Engine, Transmission, (Differential), Wheels
My drivetrain would go:
Engine, Transmission, Transmission, (Differential), Wheels
This would increase efficiency in cars, make cars faster, and all by quadrupling the amount of usable gears. Sure, the car would be heavier, and sure, there would be less room, but I am sure manufacturers could solve those problems. Maybe we could put all the gears together, in the same box.
