They've been available since 2007, unchanged.
Actually they have released second generation in 2010.
What's this, from when, powered by what?
This photo can be found on Factory Five webpages. Are you sure it isn't just a standard GTM, used to picture something based on GTM?
EDIT: I believe you we're looking for Capstone Turbine CMT-380? Build in 2009 by Capstone Turbine and Electronic Arts for Los Angeles Motor Show. But then the picture is wrong...
Yes, that is the right car.
I got the picture from a 'site where it was captioned as the Capstone but since it looks exactly like a standard Factory Five on all sites about this car I didn't think twice about it...
Below are some other pictures, some of them from the Capstone site itself, and for the life of me I can't tell any difference from the standard car apart perhaps from some different bonnet louvres and what looks like a rear-view periscope...
Anyway, this is solved and the point is yours, as you correctly say it's the Capstone CMT-380 hybrid, with a jet turbine engine charging the batteries to drive the electric motor - rather like that Jaguar concept recently. The information on the Capstone website is actually 3 or 4 years old so I wonder what became of it?
