Three-wheeler kit car hails form US

Three-wheeler socket star is easy on pocket with 225mpg returns

Riley XR-3

27th August 2007

Here’s a plug-in hybrid that you can actually build yourself. Developed by US firm Riley Enterprises, the new three-wheeler kit car, badged XR-3, is capable of 225mpg and a top speed of 85mph. It’s powered by a diesel engine at the front, while a lithium-ion cell drives a motor at the rear – you can shift between the two at the flick of a switch. Its price remains a secret, but the first kits should be ready within the next three months.
