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.
