Build your own plug-in hybrid vehicle kit

Can't wait for a plug-in hybrid? Build it yourself

Robert Q. Riley Enterprises plans to sell plans and kits for a do-it-yourself plug-in hybrid vehicle, and the company will debut the XR-3 hybrid in June of this year. According to the company, this plug-in hybrid will be a three-wheeled, two-seater capable of 225 miles per gallon when in hybrid mode. The plug-in can also be powered only by its 3-cylinder diesel engine, or it can be powered by pure electric power, however, it achieves its greatest efficiency as a plug-in hybrid.

The XR-3 has been in the press for a few years now. Hopefully, this time it's for real. Unfortunately, pricing has not yet been set.
