No gearing is bad for performance and inelegant. Tesla's cars should have a top speed over 220 given their power and acceleration. They're all limited to ~140 because no gearing.

The motors start to get inefficient even around 80mph. Telsa's have amazing 0-60 performance but get beaten by many cars on a highway roll because of no gearing.




Mid 160’s actually


Maybe, but that's above their rated specs. P100d starts out with 500 hp but also weighs nearly 5000 lbs. By 80mph back EMF has probably taken power down to about 300hp.

Essentially, at highway speeds, telsas are slower than the average pickup truck. Not as impressive as the 0-60 times
