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.
The aerodynamics are better. Drag coefficient is .23 in the Model Y LR
Vs
.28 in the Kia EV9
Weight is lower: 4,555lb in the Tesla Model Y LR
Vs
5,873lbs in the Kia EV9 with the large battery pack and AWD
The RWD version might be a bit lighter, but it’s still over 750lbs more than the largest Model Y.
These are the two biggest factors of efficiency, but there may be some other little stuff that Tesla has done to improve it.
