The new Volkswagen XL1-1 Volkswagen announced their most fuel-efficient production car in the world in the form of the 1-Liter 2-cylinder XL1 TDI.

Volkswagen XL1 conceptualization

The new Volkswagen XL1

The Volkswagen XL1 is a 2-seater plug-in hybrid vehicle that covers up to 50km in electric mode and emits next to nothing. Its concept is based on sports car design principles: low weight (795 kg), perfect aerodynamics (Cd 0.189) and a low centre of gravity (1,153 mm high).

The initial Volkswagen L1,XL1 were initially meant to be a car that’s practical for daily use with fuel consumption of 1l per 100km. With ultimate efficiency being the central theme of the concept XL1, the VW developers came up with two prototypes. The first was the L1, a two-seater set for optimal aerodynamics in 2002. Next came the XL1 with its slightly offset seating arrangement, side by side, in 2009.

The eventual production-based XL1 variant measures 3,888 mm long, 1,665 mm wide and just 1,153 mm tall. By usual automotive standards these are extreme dimensions. According to VW, even a purebred sports car like today’s Porsche Boxster is 129 mm taller (1,282 mm).

The new Volkswagen XL1-2

The Volkswagen XL1, being the most fuel-efficient production car in the world, offers a fuel consumption value of 0.9 l/100 km. Its cruising speed is constant at 100km/h as the 2-cylinder powerplant churns 8.4 PS to achieve an overall 48 PS, while the E-motor adds a another 27 PS. The combination of the 7-speed dual clutch transmission (DSG) and lithium-ion battery provides a very low CO2 emissions of 21g/km. The hybrid car’s top speed still ventures up to 160km/h and a zero to hundred sprint in under 13 seconds.

Furthermore, the XL1 requires less than 0.1 kWh to cover a driving distance of over one kilometer when the hybrid is on full electric mode.
