Now this is one futuristic ride that we won’t mind using to get about town – the XR3 plug-in 3-wheeled hybrid that was specially constructed to be as light as possible. It is now ready to enter the production phase, and we look forward to the finished product that could potentially make way for stunning mileage figures of up to 200mpg. When it reverts to its 23 hp diesel engine, the trike will achieve 125 mpg – which is more than stunning already. Should you even run out of fuel altogether, the li-ion battery pack can bring you around for another 40 miles. No idea where to seat the chick you picked up when you ride this to nightclubs though.
