Gallery: TRANSPORTATION TUESDAY: The XR3 Do-it-yourself Hybrid


Robert Riley’s XR3 is an incredible machine that is able to achieve over 125mpg on biodiesel and a whoping 225mpg in hybrid mode. With its sleek composite shell and ultra-efficient engine we were expecting to see a stratospheric price tag, however we were stunned to hear that the you can build it yourself for around $25,000! (assembly and parts not included).

    The question has to be asked, why does this individual not sell this car as is? If we the people can make the car for 25 k then surely the inventor can mass produce it for much less and resell it to dealers or to the public directly. I would love to hear an answer to this question via email and would be happy to assist in building a company if financing is the issue.

    There is a reason that folks sell this type of product as a kit. Usually, the most common is it didn’t meet transportation safety guidelines. Before anyone purchases something like this, they had better check into whether or not they will be able to license it for street use. Where I live (Alaska), a three wheeled vehicle is classified as a motorcycle. In order to register a motorcycle, the frame must have a USDOT certified marque permanently attached (I know this because I tried and was unable to register a custom built motorcycle). Unless this company provides such a certification (which most companies will not do if they are not the ones assembling the vehicle), the purchaser may be unable to register this vehicle.

    Preventive Auto Parts thinks this concept car is very cool. I am sure over time these cars will become more and more familiar to the public. I would like to see a sales lot full of these XR3\\\’s with builder/mechanics available to create as requested.

    Wow… This is a very atractive price for me, when I’m going to buy my first car.. Just make the design better, or I’ll buy a Lotus and put in my own electric engine..
