Such as Tesla Motors has been doing for years! http://www.youtube.com/watch?v=EXxOtgn8iGU Also, Tesla Roadsters have been for sale for a while now, despite the article denying the fact.

The other (Volt) has the same electric components that make it an electric vehicle in the first place with the added expense and problems that comes standard with an internal combustion engine.

The chevy volt is a good concept and in my opinion superior to something like the Toyota Prius. Pure BEV's have advantages that shouldn't be ignored either. One advantage is the life of the battery. The lower energy density cells in the Chevy Volt means the battery must be recharged more often than say Tesla's high energy pack. Batteries are only good for an X number of recharges before they degrade. Assuming the volt and tesla use the same battery type, their overall lifetime cost will be at least equal considering the Volt will need more frequent replacement though the Tesla pack costs more upfront. You see, its kind of a double edged sword. The electric vehicle business is getting pretty crazy haha. The chevy volt is a good concept and in my opinion superior to something like the Toyota Prius.

Yes, that's 1899! They have some very photos of it at Autobloggreen. Matt986: yes, the Volt concept is not new, check out the Lohner Porsche, from 1899.

I'm not doing the math but I'm pretty sure in-wheel motors hold there own on efficiency. Plus they are individually controllable so a more sophisticated traction control system can be realized. The PMLs even brake better than the disc brake friction set up. Not to mention their unsprung weight isn't really an issue.

Lotus' role was to provide some engineering analysis, ride & handling development, styling studio work and are assembling the vehicle as a contract manufacturer. Butters (#11) - Hub motors? think about unsprung mass, individual motor control, efficiency (one large motor is much more efficient than 2 (or 4) smaller ones). Dave G (#25) - The Roadster is codenamed Darkstar, not Redstar...

Still that is true of the Mailbu, too, and somehow USA Today got 3 for review that had significant problems, all different but, it seemed, all drivetrain related in some fashion. One feels that somehow what was new in the Mailbu did not get perfected by its engineers before production, i.e., nothing fundamentally wrong but in too much of a hurry to get it out the door, perhaps. I hope that does not happen with the Volt, but I once had a Chevrolet Citation --- highly praised, hurriedly constructed -- so it is easy for me to imagine. #38 Rashid,

Now that they are starting to jump in, Tesla is in a race against time to establish a foothold. I see them making the Roadster for a couple years and then getting bought out or folding. There is no way WhiteStar will compete in the marketplace with a Volt at 20K cheaper. The only way Tesla could succeed was for the automakers to continue to ignore their market.
