Robert Q. Riley Enterprises, a product design firm in Glendale, Ariz., has released construction plans for anyone who wants to build its XR3, a two-passenger, plug-in hybrid that can travel up to 225 miles per gallon.
“During the two years it took to develop the XR3, we received more than 2,500 advanced order reservations for the plan set,” states Robert Q. Riley company president and author of “Alternative Cars in the 21st Century.”
In addition to conventional printed drawings and instructions, the do-it-yourself plans include electronic 3D models that can be viewed on an ordinary PC, computer files vendors can use to make parts, and a DVD that shows the car being built.
The plans cost $200.
“We’ve taken CAD technology used by today’s designers and put it in a form that anyone can use,” adds Riley, whose alternative vehicle designs have regularly appeared in how-to magazines. “Not only is there nothing like the XR3 coming from the world’s carmakers, there’s nothing in the DIY field that’s even close to the information technologies we’ve used in the XR3 plan set.”
The XR3’s Li-Ion battery pack can achieve 80 percent of its full charge in just 1.5 hours by plugging into an ordinary wall outlet, according to the company. Although 40-50 miles is possible on battery power alone, switching the car to diesel power and its three-cylinder engine can result in up to 375 miles on a mere three gallons of fuel.
