Tesla Boosts Range Without Adding Battery Capacity

Tesla announced a 10-percent increase in range for both the Model S fastback and Model X crossover. The improvements were achieved without adding battery capacity but through a revamp of the power systems. A permanent magnet motor in the front and an induction motor at the rear wheels were changes that improved efficiency. Silicon carbide power electronics and improvements in lubrication, cooling, bearings and gear design also had an impact. The new estimated ranges are 523 km for the Model X and 595 km for the Model S, the highest EPA-rated range for an electric vehicle to date.

The upgraded models can now be charged with Tesla’s V3 200-kW and V2 145-kW Superchargers reducing charge time by up to 50%. Standard Range models have also made a return with improved range and increased speed.
