When you say "gearboxes" as in traditional multi ratio transmissions? If so, are you 100% sure about that?

When you say "gearboxes" as in traditional multi ratio transmissions? If so, are you 100% sure about that?
- pcl 4y agoIIRC the Tesla Roadster had a 2-speed transmission initially, due to engineering challenges with high-rpm bearings. But they struggled with the engineering challenges of high-torque transmissions, and eventually sorted out the bearing issues and went back to 1-speed.
- elihu 4y agoMost EVs have a single-speed gearbox. A few have multiple gear ratios, but it's not common. (It's not unusually for ICE vehicles converted to EV to retain a manual transmission, but conversions aren't being done in large numbers.)
- dogma1138 4y agoFor conversions you usually find an optimal reduction ratio for your motor and whilst you can reuse the transmission it’s fairly rare that you continue to operate it.
- dogma1138 4y agoThey have gearboxes with a fixed ratio that is optimal for the vehicle, some have variable speed gear boxes 2-3. The motor isn’t just connected to the drive train in 1:1 that won’t end up well for neither the drive train or the motor.
