What is your feelings about the range-extender concept of the Chevy Volt and why have you not considered it it any of your products?We looked closely at a range extender architecture for Model S. It ends up costing about the same in vehicle unit cost, a lot more in R&D and a lot more in servicing. Also, although performance is ok when both battery and engine are active at the same time, it turns really bad when the battery runs out and an undersized engine is carrying all the dead weight of the pack. Essentially, a REV is neither fish nor fowl and ends up being worse (in our opinion) than either a gasoline or pure electric vehicle.
