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.
Weight and drag coefficient play a big role. Tesla has really taken care to optimize their cars structure to reduce weight where possible. Thats why the battery box is a structural part of the car. This results in having to move less mass, which means there is not as great a need for a large battery, which in turn reduces mass. Add on top a “slippery” car and efficient power train and you get a result of managing to drive further with less.
Although it is prudent to point out that the WLTP claims are not always very accurate and can be nudged by manufacturers quite a bit. Take the Porche Taycan for example which generally gets more than the WLTP vs any Tesla which usually get less even if you drive them past 0 unless it is really perfect weather conditions.
