Test drive: DC to Boston in a Tesla Model S
Not really a surprise - I don't think there was really any doubt about the performance of the Tesla in normal weather. The NYC area right now is well above freezing, approaching +10C in the daytime, nowhere near the deep freeze that occurred during the NYT drive.<p>This still doesn't put to rest the expected (but somehow controversial) concerns about lithium battery performance in cold weather. This concern IMO needs to be put to rest if electrics want to break into the mainstream market. Early adopters may be willing to plan judiciously around range and expected weather, but I doubt mainstream consumers will be so forgiving.<p>Having a car of (somewhat) limited range lose a large chunk of its battery just sitting overnight in a parking lot, in weather that is cold but hardly unusual for the region, is a problem. That both on-board software and human advisers seem poorly prepared to compensate for this is hardly a nail in Tesla's coffin, but does need to be sorted out.
