""Tesla's chief technology officer, J B Straubel, acknowledged that the two East Coast charging stations were at the mileage limit of the Model S's real-world range. Making matters worse, cold weather inflicts about a 10 percent range penalty, he said, and running the heater draws yet more energy. He added that some range-related software problems still needed to be sorted out.""
Bottom line, people still expect to get in their vehicles and drive. If there is a specific range that the particular vehicle can handle, then the driver understands this. But does not expect to have to keep track of battery temperature/range effects. The operation of accessories,(the heater in this case) and a decrease in range or higher highway speeds as opposed to running under 50MPH on some city navigated trip. Basically, do not make mileage estimates based on no accessory drain or uphill climbs. This is not the type of daily driving a majority of people will be doing. If the electric vehicle can go at highway speeds with 350 watts per mile, it might take 600 to 800 watts per mile If accessories are being used (like the heater). Now the 200 mile claim is more like a 75 mile actuality taking into account the entire power requirement of the vehicle along the trip route. For the 100K price range, most would prefer something like the BMW, Mercedes, Porsche or one of the many other luxury cars out there now.
