Even though we've finally gotten a look at the production version of the 261-mile per gallon Volkswagen XL1, this aero-shaped two-seater was never intended for high-volume sales. Fortunately, it sounds like the same isn't true for the car's diesel plug-in hybrid powertrain, which, according to a report from AutoCar, could make its way under the hood of another Volkswagen model: the Up. minicar (shown above). A potential Up! Hybrid would likely be able to return some of the same impressive fuel economy numbers as the XL1, but it would be a more realistic car with more passenger space and greater production capacity.
