vfx, I wouldn't throw in that bit about the power required increasing by a factor of eight when speed doubles, because the issue under discussion in the article is range, not power. The Model S has plenty of power...:wink:

Right, but you'd be overstating the effect of drag on range because the car will be covering the ground twice as fast. It's 8x per unit time, but only 4x per unit distance. Why confuse the issue?

It seems to me that the bottom line on all this is that Tesla needs to be a little more frank about what the actual capabilities of the car are in cold weather and they desperately need to fix their range estimation software.
I for one would really appreciate it if you'd post your experiences with highway driving in cold weather. I'm assuming that even in March, Chicago will be able to supply some cold temps. :smile:I agree. I'm still waiting for my Model S (vin 5476; expected delivery in two weeks), but I currently have a Volt and I notice dramatic changes in the range based on temperature. In the summer, I'd easily get around 45 miles on a charge. In the winter in Chicago, when the temperature is in the mid twenties, the range is more like 26 - 28 miles. This drop off in range is the main reason
I decided to get the 85kW hour battery on my Model S - I assumed that there would be a similar degradation. I'm looking forward to seeing what the actual range is, once I get the car.

.. While a good review from CR isn't going to help Tesla much, ....
Agreed... they also need so stop talking about 300 miles estimated range because it generates a climate of mistrust IMO.It seems to me that the bottom line on all this is that Tesla needs to be a little more frank about what the actual capabilities of the car are in cold weather and they desperately need to fix their range estimation software.

I don't agree with some of the comments here that winter driving should be done with a range charge. As the article points out, most people, myself certainly, will be doing range charges very rarely or not all because of the battery degradation warning.
It looks like the range estimator on the Tesla site must be assuming a range charge as well since they show over 210 miles for those conditions. It would be nice if the calculator covered lower temperatures and allowed specifying normal or range charge in addition to if the windows are rolled down and the lights on.
It would be interesting to know what the real range is on a standard charge, driving at 60-65, with the temps around 28-32.

No one is getting 300 miles unless their sole intention is to do so. 200 miles on a range charge would be my limit of comfort and that would be without going over 65MPH.
