After years of rumors, development and testing, the Volkswagen XL1 is finally about to become a reality. The project that began life as a daring 1-Liter concept car in 2002, will finally get its production-ready curtain call at the Geneva Motor Show in just a few weeks.

As soon as it hits the streets, the two-seat XL1 will instantly become the most fuel-efficient and most aerodynamic production car in the world. The car uses a plug-in hybrid system to achieve mind-blowing consumption of just 0.9 liters of diesel fuel consumed every 100 kilometers (and average of roughly 261 miles per gallon). Plus, the XL1 can go up to 50 kilometers on its battery power alone. Coefficient of drag is a miniscule 0.189, thanks to a tiny frontal area and an obviously slippery shape.

XL1 power comes from a 47-horsepower, two-cylinder diesel motor connected to a seven-speed dual-clutch gearbox, while the 20 kW (27 hp) electric motor is fed by a lithium-ion battery. Both combine to give the XL1 performance figures that are, while not stirring, not shabby considering its extreme frugality: 0-62 miles per hour comes up in 12.7 seconds and top speed is nearly 100 mph.

There's still no word as to how many examples of the XL1 Volkswagen plans to build, nor how much the company intends to charge for each. The press release does mention that the car will be constructed using "handcrafting-like production methods" though, so we're guessing that it won't be cheap or ubiquitous – not by a long shot. Early rumors had a six-figure price tag attached, suggesting the XL1 be viewed as more of a green halo supercar for VW than a volume proposition.

Launch of the 1-litre fuel economy car from Volkswagen

Volkswagen to produce XL1 by handcrafting-like production methods at its Osnabrück plant in Germany

XL1 is the most aerodynamic production car ever

0.9 litre combined fuel consumption was a vision – now it is a reality
Wolfsburg, 21 February 2013 - The XL1 from Volkswagen is the most fuel-efficient production car in the world, with a fuel consumption value of 0.9 l/100 km. Thanks to its plug-in hybrid system, the two-seater can also cover a distance of up to 50 km in all-electric mode and therefore with zero local emissions.

The XL1 is an automotive hero that follows pure sports car design principles: low weight (795 kg), perfect aerodynamics (Cd 0.189) and a low centre of gravity (1,153 mm high). This gives the efficient Volkswagen the ability to cruise on the road at a constant speed of 100 km/h using just 6.2 kW / 8.4 PS. In all-electric mode, the XL1 requires less than 0.1 kWh to cover a driving distance of over one kilometer.

High-tech lightweight design, perfect aerodynamics and a plug-in hybrid system – consisting of a two-cylinder TDI engine (35 kW / 48 PS), E-motor (20 kW / 27 PS), 7-speed dual clutch gearbox (DSG) and lithium-ion battery – all make it possible for the new Volkswagen XL1 to emit just 21 g/km of CO2. If necessary, the XL1, with a top speed of 160 km/h, can accelerate to 100 km/h in just 12,7 seconds. Clearly, 0.9 l/100 km fuel consumption is a record figure that has not been achieved by any other vehicle to date, and it illustrates how Volkswagen is redefining what is technically feasible in carmaking.

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.

The XL1 is 3,888 mm long, 1,665 mm wide and just 1,153 mm tall. By usual automotive standards these are extreme dimensions. For comparison: a Polo has a similar length (3,970 mm) and width (1,682 mm) but is significantly taller (1,462 mm). Even a purebred sports car like today's Porsche Boxster is 129 mm taller (1,282 mm). So, the XL1 will make a spectacular appearance – a car of the future, built for today.

      Umm... for those journalists that can't read... or do math... "the XL1, with a top speed of 160 km/h," 160km/h is 100 mph... not 146.
        • 2 Years Ago
        i always try to keep it under 100 anyway. lol.

        The car is electronically limited to 160km/h. Otherwise the top speed is said in German) to be 200 km/h.

      If a company wants to show its engineering skill, its harder to make a car more efficient than it is to make it faster. I think what VW is doing is pretty cool. If I was a real geek engineer, this would be the type of project I would like to work on.

      I wish they brought it here with the diesel intact and a price around $50k, that would seem reasonable considering engineering costs. But six figures? Sorry even for someone like me who is a diesel MPG freak thinks that's a bit ridiculous.

      Look at those motorcycle width tires! This thing must be light. I can't believe that they through so much tech into a one car: plug-in, diesel, super areo, dual-clutch, indirect mirrors, ect.

          Its easy to design optimize for Eco-marathon, but to make a consumer car that sells, than is a lot harder. For example: The XL1 will have a hard time sell because it has no cargo room. It also has a very slow (by today's US standards) 0-62 MPH time. The later is more of a spec creep, because who regularly accelerates 0-62 in

      \"Rated\" (European cycle) MPG 261, real world gas mileage (likely under 150 MPG if that).....

      If reasonably priced, I would be interested. Unfortunately, I fear it won\'t be reasonably priced.

      Yah but can this thing tow my imaginary boat or haul my 5 imaginary kids to soccer practice? This project is awesome since the whole VW group of cars will benefit from the technology from this car. Interestingly this thing looks a lot like what an update EV1 would have looked like.

      I"ve averaged 270 mpg over a year and 16,000 miles in my Chevy Volt. And it's a good sized car with creature comforts.

      Hand-built? They are clearly not serious and it is just a Halo car. Weird. If you go green for a Halo car it is generally a compliance car.

      looks like a supercar with the performance of an UP and the fuel consumption of a petrol lighter.

      Really cool.
      • 2 Years Ago
      Very cool.
