No harm, no foul.
The "artificial price" of the Tzero is surprisingly NOT inflated. The three cars they've sold, have been at cost: About $120k. There are LOTS Of fixed costs that need to be spread over thousands of cars before any vehicle like this can be economically viable. There are only a handful of "off the shelf" parts in the Tzero.
Yeah, the Tango is dorky looking. But you have to admit that it is unique in a time when most other "normal" cars all start to look the same.
Now, if we had a real battery industry, mfg's could design their cars around current, available battery technology. Sadly, that is not the case, and cars are designed around 8-year-old technology out of necessity. For car makers to hope for any kind of battery R&D that would offer high capacity, low cost batteries would be foolish at this point.
As far as I'm concerned, both of these vehicles (Tango and Tzero) could see similar price/margins. It is all about scale. The Tango is hoping for mass production while the Tzero has always been considered a technology car. Did I mention that the Li-ion Tzero is just weeks away from completion? They're buiding it on contract for a buyer. Can't wait to see the real specs. They are fully expecting 0-6 in 3.something seconds. And it will have the capability for quick-charge in just 10 minutes (like they all do).
