Tesla's Model S and Model X get new motors with more range
Unlike most automakers, Tesla has refreshed the designs of its existing cars on rather sporadic schedules, and the latest tweaks for its Model S and Model X are here. Confirming earlier rumors, the flagship sedan and SUV are getting a redesigned powertrain that uses the same "permanent magnet synchronous reluctance motor" and associated technology we first saw in the Model 3. It uses a permanent magnet motor up front to either power the car or regenerate energy under braking, with an induction electric motor in the back that engages when extra power is needed. Production on the updated versions will start this week at its Fremont factory and buyers can start ordering them online today.
