The Tesla Model S could see a slew of significant updates that 
include an extended driving range, streamlined interior design, and new 
drive motors. Much of this fresh content could be cribbed from the more 
contemporary Model 3 according to speculation in a report by CNBC.
The last time Tesla overhauled the Model S was back in 2016 when it received a more expressionless face and improved range.
 Apparently, this re-refreshed version will retain the existing 
sheetmetal but adopt a simpler dashboard design similar to the 
simplistic aesthetics found on the Model 3. Inside, the smaller Tesla 
relies on a large 15.0-inch touchscreen that is horizontally mounted in 
the center of the dash and controls most of the car's functions. The 
current Model S boasts a more complex dashboard with a fully digital 
gauge cluster and a vertical touchscreen that measures 17.0 inches. The 
refreshed Model S could also add the same seats found on the fanciest 
Model 3. However, it's unclear whether these new chairs would be limited
 to the front seat or spread to the three-person bench in the back of 
the S. Although switching to the 3's streamlined setup as seen below 
could be considered less luxurious, it would likely help cut down on 
production costs.

Perhaps most important, the updated Model S is said to offer an even longer driving range than the rangiest Long Range model, which currently has an EPA-estimated driving range of up to 370 miles. According to reports, the latest Model S will feature a battery capable of driving 400 miles on a single charge. The largest Tesla could also get new drive units courtesy of the Model 3.
While the CNBC report cites "several current and and former employees," Tesla hasn't confirmed these reports, so this information remains mostly speculative. Likewise, the polarizing startup company is reportedly retooling its factory in Fremont, California, in preparation to begin building the upcoming Tesla Model Y crossover as well as the refreshed Model S. Again, nothing has been officially announced by Tesla or its embattled CEO, Elon Musk.
