Even though we’ve finally gotten a look at the production-version of the 111 km/liter VW XL1, that aero-shaped two-seater was never intended for high-volume sales. Fortunately, it’s not the same for the revolutionary diesel plug-in hybrid powertrain, which could make its way under the hood of another VW model: the Up! mini car.
A potential Up! Hybrid would likely be able to return a similarly impressive fuel economy numbers as the XL1, but it would be a more realistic car with more passenger space and greater production capacity. As previously announced, the hand-built XL1 uses a 47-horsepower, two-cylinder 800cc engine paired to a seven-speed dual-clutch transmission, and the 27-hp electric motor and lithium-ion battery helps deliver an all-electric driving range of 50 km.
One of the core pillars of the XL1′s design is its lightweight construction with a 795 kg weight, and the Up! is a perfect recipient for using this powertrain since it weighs just 150 kg more. The Up! Hybrid is still in the developmental phase, so a production version isn’t expected for at least another 18 months.
