The Tesla Roadster and the company’s upcoming Model S are both pure electric-vehicles. That’s because Tesla Motors CEO Elon Musk doesn’t like E-REVs like the 2011 Chevrolet Volt.
When asked by GM-Volt why Tesla hasn’t considered the range-extender concept of the Chevrolet Volt, Musk said:
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.
Of course, there is a more technical hatered for Musk towards REVs. You can read more over at GM-Volt.
