Come qualcuno aveva sniffato nell'aria tempo fa, la Model 3 ha cambiato tecnologia di motori, non piu gli AC ad induzione.
Nessuno si aspettava invece la frenatura rigenerativa su tutte e 4 le ruote.
Efficienza totale EPA di 126/128 MPGe di gran lunga migliore di Model S che a stento arriva sotto i 110 MPGe, anche se ancora sotto lo straordinario valore di Hyundai Ioniq EV a 136 MPGe (ma il motore è DC brushless)
Ottimo lavoro....

Other interesting information from the filing includes the confirmation that Model 3 is using a 3 phase permanent magnet electric motors, which is a departure from Model S and Model X’s induction motor.
The AC induction motor was invented by Nikola Tesla and it was a big part of the heritage of the namesake company. Most electric vehicles today, cars or otherwise, use permanent magnet motors – so it’s a natural shift that a car aimed at the mass market would also use the proven technology.
We also learn that the Model 3’s rear-wheel-drive motor is rated at 258 horsepower, according to the document. As expected, it’s less powerful than the standard Model S/X RWD motor, but a more powerful version is expected to be released for the performance version of the car, as well as a dual motor version next year.
Another interesting tidbit of information from the same document is that Tesla is listing regenerative braking from both axles instead of just the rear, like it does on RWD Model S vehicles.
During my short test drive of the long range RWD Model 3, I found that the regenerative braking was a lot smoother than what I am used to in my Model S P85, which is also rear-wheel-drive.
Furthermore, they released some dyno tests for city and highway driving:
Those are tests performed on a dynamometer and not the final EPA ratings based on their driving cycles, but they are promising.
The Model 3 will easily be one of the most efficient production cars ever made based on those test.
