"The particular Model S I flew to Los Angeles to sample last week was a Signature Performance model." I'm going to call Tesla's bluff. If you want to convince customers who live in climates with cold winters that the Model S is winter-capable (perhaps for taking the family road trip to somewhere warm from somewhere cold during the winter), then set up the journalist test drives in cold weather locations. Based on the Tesla Motors Club forum discussion of a recent review of the Model S http://www.teslamotorsclub.com/showthread.php/13633-NYT-article-Stalled-on-the-EV-Highway http://www.teslamotorsclub.com/showthread.php/13633-NYT-arti... (kindly shared here on HN by another participant), I'm gravely doubtful that the Model S will ever be a practical car for the parts of the United States that are generally called "the north," rather than just for California. The review submitted here is very detailed and well worth reading in full. The Model S has some interesting design trade-offs, and the writer is frank about what he likes and what he doesn't like about the car.
