Time will tell whether these JDM changes make it in full to the (Smryna built?) USDM model. Key changes include: 10% more range, possibly by virtue of strengthened regenerative braking; optional leather upholstery and a Bose stereo; and, possibly most significantly, the substitution of a heat pump in place of a pure resistive heating element.

This last is important because the >1 coefficient of performance of a heat pump will halve or perhaps cut by two thirds heating loads and the resultant range loss.

In any case, the outside appearance isn't changed. Here's the outside, in case you've been living under a rock, as well as the new interior leather:





Other notable vehicles in terms of HVAC: The PHEV Prius prototypes (but not the production model) also employed a heat pump, and the Volvo C30 EV prototypes employ a small biodiesel burner for auxiliary heat, of all things. Finally, the series 200 Land Cruiser and its Lexus cousin boast of the following:
