In a recent Telsa newsletter I received, it referred to an article http://www.insideline.com/tesla/model-s/tesla-moves-up-model-s-launch-to... that stated after EPA tested the 85kWh model, they rated it as having 265mile range NOT the 300 miles that Telsa has always stated. This may be due in part to the 5 cycle test that they utilized instead of the 2 cycle test used in the past which yielded 320miles! I do not understand what these tests are nor the difference. EPA’s new 265mi result is only 20mi further than the Roadster’s 245mi range which has been battery technology which has been out for years.
I do know that when I had made the decision to upgrade from the base 40kWh model to the 85kWh model and pay $20,000 additional to do this, it was for the sole purpose to obtain 300 miles at 55mph as Telsa has told everyone.
1. So if I take my fully charged 85kWh S model on the interstate at a constant 55mph no AC or other power drains flat terrain etc, will my range be 300miles or 265miles?
Are the 230 and 160mile versions also now less than stated per EPA testing?
2. I realize if I go 70mph, my range may be expected to be 70% of the official stated range of: 300 or is it now 265miles?
3. If it is now 265mi, will Telsa add a small supplemental trunk battery to compensate for the now EPA missing 35miles+265=300mi ? This would help deliver on the promise of a 300mile electric car.
I hope Telsa can clarify and reassure us about this battery range issue since delivery is ahead of schedule, now June 22, 2012! It should be noted that I am very proud of Telsa overall and all of it’s accomplishments and innovations that Elon Musk and his engineering team have given leadership to and have been creative in solving issues such as this. Thanks.
