Another vehicle we may see in the future is the XR3. The XR3 is a three-wheeled vehicle shaped like a triangle . The point of the triangle rests over the single rear wheel. Its unique shape and shiny silver exterior give the car a futuristic style . What makes the XR3 so different is that it can be built at home, and you don’t have to be an automotive expert to build it. Clear instructions and materials can be bought from the designer. Known as a “personal transit vehicle,” the XR3 holds one person. It’s a hybrid car that runs on both electricity and gas and gets 125 miles (201 kilometers) per gallon (3.8 liters). The XR3 is designed for people who want to save fuel and build their own vehicle. For this reason, the designer is confident that the XR3 is the car of the future
