Conceptually, the XL1 represents the third evolutionary stage of Volkswagen’s 1-litre car strategy. When the new millennium was ushered in, Prof. Dr. Ferdinand Piëch, who is today Chairman of the Supervisory Board of Volkswagen AG, formulated the visionary goal of bringing to market a production car that was practical in everyday use with fuel consumption of one litre per 100 km. In the two-seat XL1, this vision has become reality. Despite the tremendous efficiency of the XL1, developers successfully came up with a body concept, which delivers more everyday utility than in the two previous prototypes. While the driver and passenger sat in a tandem arrangement for optimal aerodynamics in the L1, the 1-litre car presented in 2002 and in 2009, in the XL1 two occupants sit slightly offset, side by side, nearly as in a conventional vehicle.
