Robert Riley’s XR3 kit car is an amazing three-wheeled plug-in diesel hybrid. The trike gets a jaw dropping 225mpg on combined diesel-electric power and 125mpg when using only the 23hp diesel engine.

And hey, it kinda looks like that Back to the Future car!

Introduced back in June of 2008, the two-passenger car was designed so it can be assembled using readily available parts. Fully constructed, the car weighs in at 1480 pounds and has top speed of 80mph. And while you can only get 40 miles out of its li-ion battery pack, it can be plugged into any standard wall socket.



It’s an all-wheel-drive, ground-connected parallel hybrid, which means there’s no mechanical transmission between the two systems. It relies fully on the ground to provide the connection. The car can be ran in diesel-only, battery-electric-only, or hybrid modes.

Riley’s site says that anyone with moderate skill can build the bike:

Plans enable people with common building skills to build a duplicate of the XR3 Hybrid prototype or convert their own car into a significantly more fuel-efficient vehicle. Readers will understand the factors that influence fuel economy, and learn how to make any car achieve greater fuel economy. The XR3 Hybrid gives enthusiasts and experimenters the opportunity to significantly reduce their transportation expenses and have fun doing it.
