As Germany’s largest automaker, Volkswagen had big news at the Frankfurt Auto Show today with numerous new models that boast impressive fuel-economy. But even the BlueMotion Polo has nothing on the fuel-economy of the L1 Concept, a tiny two seater that uses just 1.38 liters of diesel per 100 km – that’s 170 mpg. And for some reason it doesn’t look as dorky in real life as VW’s promo photos suggested.
The car is a two-seater, although the passenger sits behind the driver.
The engine is an 800cc diesel motor mated to a hybrid drivetrain and a seven-speed DSG transmission. It makes 27hp in ECO mode and 39hp in a more powerful mode. Torque is rated at 74 ft-lbs.
Along with this motor the L1 Concept gets a start-stop system, a light-weight carbon fiber body that is just 838 lbs and a drag coefficient of just 0.195.
Volkswagen calls the L1 Concept a “near production vehicle,” and says a production version is expected by 2013.

To the Point: Breakthrough for the 1-Litre Car
Volkswagen presents the most fuel-efficient automobile in the world
- L1 Concept is driven by new high-tech TDI and E-motor
- Carbon Fibre Reinforced Plastic body of the L1 weighs just 124 kilograms
- Maximum speed 160 km/h; L1 consumes just 1.38 litres diesel per 100 km
- CO2 emissions reduced to a new best value with just 36 g/km
Wolfsburg / Frankfurt, 15 September 2009 – Technological breakthrough for the 1-litre fuel consumption car: International Motor Show (IAA), Volkswagen is presenting the concept of the future L1 in a world premiere that points the way toward the production version. The full hybrid vehicle weighs just 380 kilograms thanks to its carbon-fibre reinforced body (CFRB). With a combined fuel consumption figure of 1.38 litres of diesel per 100 kilometres, this extremely aerodynamic (Cd 0.195!) Volkswagen suitable for everyday use is intended to become the most fuel-efficient automobile in the world. CO2 emissions of the 160 km/h L1 are similarly low at 36 g/km.
Retrospective: Seven years ago, Dr. Ferdinand Piëch, at that time Chairman of the Board of Management and today Chairman of the Supervisory Board of the Volkswagen Group, drove a prototype from Wolfsburg to Hamburg that was unlike any other car before it: the Volkswagen 1-Litre car – the world’s first car with fuel consumption of one litre fuel per 100 kilometres. The man and machine wrote automotive history. In April 2002, however, it was also clear that the time for a production version of the 1-Litre car lay far in the future. Production of the body itself – from carbon-fibre reinforced plastic (CFRP) – was not realistic due to cost considerations. Yet, in 2002 Dr. Ferdinand Piëch already prophesised that the time would soon come for the 1-Litre car and CFRP as a material for industrial applications. By 2009 the time had come: Volkswagen is making a clear statement at the IAA in Frankfurt (September 17 to 27) with the second generation of this ingenious car: The L1 represents a step forward into the future with completely new technology and a new design; revolutionary yet close to production readiness.
“It is an enormous challenge to control costs in producing the monocoque out of CFRP,” says Dr. Ulrich Hackenberg, member of the Board of Management for the Volkswagen Brand with responsibility for development. Both technically and visually, the CFRP body is already considered a significant achievement in car design. Unique on this car are the proportions of its dimensions. While the length of the L1 at 3,813 millimetres is still similar to that of a Volkswagen Fox, and its height of 1,143 millimetres nearly matches that of a Lamborghini Murciélago, the car’s aerodynamically optimised width (1,200 millimetres) has no comparisons in the world of today’s production cars.
L1 philosophy – defining a new type of automobile
In developing both prototype generations of the L1, Volkswagen simply questioned everything that typically characterised an automobile. The key starting point was body construction, and a core question was raised here: How would a car have to look and be built to consume as little energy as possible? The logical answer: extremely aerodynamic and lightweight. Yet these objectives had to be achieved under a non-negotiable precondition: a maximum of safety. The approach taken: a narrow two-seater with a CFRP body!
The seat layout fitting this design goal was dictated by the uncompromising aerodynamic form of a glider: One seat behind the other. Entry to the concept car is also similar to that of a glider; through a roof cover hinged at the side. On this second generation of the L1, the concept has been further honed; each component has been redesigned, a special chassis with aluminium components was developed, and above all the crucial CFRP technology from Formula-1 racing and airplane construction was transferred to automotive manufacturing. This has been combined with a unique form of hybrid drive to create a near-production vehicle. 2013 is the target year for this future dream to become a reality.
