Back in 2009 VW unvealed the L1 concept as the most fuel efficient no hybrid production car in the world, later after 2 years VW reintroduced the car under the name XL1 which will be it’s production name.
the XL1 is fitted with a 1.0 L 48 hp two cylinder TDI engine with only 24 g/km of CO2 gases and fuel economy figure of 0.9l/km (261 mpg US / 313 mpg UK) although It’s still unclear exactly what will power the production XL1, though the concept car featured a two-cylinder TDI diesel paired with an electric motor, lithium-ion battery pack and seven-speed dual-clutch transmission. It might look big and sleek, but the XL1 is about as long and wide as a Volkswagen Polo. It should be ultra-light, too – the concept version tipped the scales at just 1,753 pounds.
here is a video & some photos by WCF of the VW XL1.
