Motor of battery pack + motor + lader ?
Groot verschil.

Tesla mod S/X had toen 2 asynchrone motoren, nu hebben ze de synchrone motor van het model 3 vooraan gekregen en verder nog geoptimaliseerd op mekaar voor meer range, zou tot 10% meer range geven (wslk bij hoge snelheden):

Motor technology from Model 3 helps Tesla boost Model S range 10%
New motor design helps Model S to drive 370 miles on a charge.

The dual-motor versions of the Model 3 have an induction motor in the front and a permanent magnet synchronous reluctance motor in the back. The Model S and Model X switch this around, putting an induction motor in the back and a PMSRM in the front.
Combining an induction motor with a PMSRM makes sense because the two motor types have different performance characteristics. As Elon Musk put it last year, "one is optimized for power & one for range." Induction motors offer high torque at low speeds, but they're less energy-efficient overall. So dual-motor vehicles can send power to the induction motor when immediate, rapid acceleration is called for, then shift power to the PMSRM as the vehicle gets up to speed.
Tesla says that the Model S and X efficiency gains haven't come at the expense of reduced torque. To the contrary, the company says the latest versions have improved 0-60 times compared to earlier iterations.
