VW started working on the one-liter car concept back in 2002. In 2014, the production of the 200 units of the XL1 had begun. According to the manufacturer, fuel consumption is less than 1 liter per 100 km, to which the low overall mass of the model contributes significantly.
The history of cars with bodies made of glass-fibre-reinforced plastic (GFRP) dates back to the 1950s. Paving the way for mass-produced cars with plastic bodies, the Corvette C1 appeared in 1953 and was the first stage in the Corvette success story.
