Volkswagen XL1

Volkswagen has announced plans to build the most fuel-efficient production car in the world, with a European combined fuel consumption rating of just 0.9 L/100 km (261 mpg US).

Called the XL1 it is a sleek two-seat commuter car with an aerodynamic drag coefficient (Cd) of just 0.19 – which will also make it the most aerodynamic car in production.

Thanks to extensive use of carbon-fibre in its construction, it will tip the scales at just 888 kg (1953 lb).

With its light weight and exceptional aerodynamics, it will require just 8.3 hp to maintain 100 km/h on a level road, according to Volkswagen.

Its plug-in hybrid drive system comprises a 47-horsepower, two-cylinder diesel TDI engine, a 27-horsepower electric motor, a seven-speed DSG dual-clutch automatic transmission, and a lithium-ion battery pack.

VW says it can be driven up to 51 km on electric power alone, using just 0.1 kWh to cover more than a kilometre.

It is said to have a top speed of 159 km/h and to accelerate from 0-to-100 km/h in a leisurely 12.7 seconds.

The XL1 represents the third evolution of Volkswagen’s 1-litre car strategy, realizing supervisory board chairman, Prof. Dr. Ferdinand Piëch's long-time goal putting into production a practical car with fuel consumption of just 1L/100 km.

The car will be built at VW's plant in Osnabruck, Germany, the company says, although no timetable has been announced.
