I’m assuming this could be why Tesla’s are so cheap compared with similar electric cars.

Let’s take the model y LR and the Kia Ev9 Earth.

The model y LR has a range of 533km with a 75kwh battery

The ev9 earth has a range of 512km with a 99.8kwh battery.

That’s 14.8kwh more than the Tesla and 21km LESS range than the Tesla.

Is Tesla’s cars just more efficient? And by that much??

There’s no way Tesla can be that much more efficient with it’s motor, aerodynamics and electronics. (What am I missing?)

Other brands should be able to do somewhat the same. An electric motor isn’t a complex machine and aerodynamics can be easily improved upon. Same for electronics.
