Tesla Model S Driving Range Estimates Updated

Tesla 2
At the end of 2014, Tesla Motors updated its Model S driving range estimates for all variations of the car. Based on the EPA 5 cycle test, the numbers are as follows:
  • Model S 60 — 208 miles
  • Model S 85 — 265 miles
  • Model S 85D — 270 miles
  • Model S P85D — 253 miles
Tesla fans will note right away that the EPA numbers are significantly lower than what the company claims to be the maximum range for the various models on its website. It has an online range toolthat explains this discrepancy and offers insight into how ambient temperature and type of driving will affect range in real world driving. Apparently, wheel size and type of tires fitted both have a noticeable effect on range.
Interestingly enough, Elon Musk was recently caught deleting a few tweets as they related to an actual increase in range with the Dual Motor drive. And indeed, the 85D gained about 5 miles of range over the standard Model S, but the P85D loses at least 12 miles of range, and more with the 21-inch wheels.
One factor that may surprise drivers who have never owned an electric car before is how much outside temperature effects battery performance. In frigid climates, actual range will be substantially reduced, something you should be aware of if you are taking your Model S to the mountains on a ski trip this winter. While gas cars also lose range, filling them up is still much easier, unless you happen to be near a Supercharger.
