Volkswagen Formula XL1 Concept – Click above for high-res image gallery

Volkswagen has taken another step towards making the one-liter car a reality, and this 200 mile-per-gallon dream could be on the roads within the next few years.

The Formula XL1 Concept combines a two cylinder TDI engine, electric motor, lithium-ion battery pack and a seven-speed dual-clutch transmission to achieve an astonishing 0.9L/100 km – just over 260 mpg to us Yanks. The included plug-in system, along with the XL1's low drag and extensive use of lightweight materials has the potential to make the concept the most efficient vehicle to ever grace public roads.

The XL1 is making its debut at the Qatar Motor Show this week, and while it might look familiar to previous iterations, this latest version is more production read than its predecessors. Check it out from every angle in the gallery below and click past the jump for the full details.

Vision becomes reality – Volkswagen's "Formula XL1": Volkswagen XL1 prototype consumes just 0.9 l/100 km!
XL1's world debut at the Qatar Motor Show (26 - 29 January)

Two-seat XL1 brings vision of the 1-litre car close to production maturity
Wolfsburg / Doha, 25 January 2011 - Future mobility is one of the most stimulating topics of our time. The key question here: Just how much could the energy consumption of cars be reduced if all the stops were pulled out for efficiency? There is now an answer to this question, and Volkswagen is delivering it in the form of the new XL1. Combined fuel consumption: 0.9 l/100 km. No other hybrid car powered by an electric motor / internal combustion engine combination is more fuel efficient. The prototype will be unveiled in a world debut at the Qatar Motor Show (26 - 29 January).

To the point
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 the market a production car that was practical for everyday use with a fuel consumption of 1.0 litre per 100 km. In the new XL1, Volkswagen is demonstrating that this goal is now within reach.

The new Volkswagen XL1 attains a CO2 emissions value of 24 g/km, thanks to a combination of lightweight construction (monocoque and add-on parts made of carbon fibre), very low aerodynamic drag (Cd 0.186) 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 transmission (DSG) and lithium-ion battery. The results: with fuel consumption of 0.9 l/100 km, the new Volkswagen XL1 only emits 24 g/km CO2. Since it is designed as a plug-in hybrid, the XL1 prototype can also be driven for up to 35 kilometres in pure electric mode, i.e. with zero emissions at point of use. The battery can be charged from a conventional household electric outlet. Naturally, battery regeneration is also employed to recover energy while slowing down and store as much of it as possible in the battery for re-use. In this case, the electric motor acts as an electric generator.

Despite the very high levels of efficiency, developers were able to design a body layout that offers greater everyday practicality, incorporating side by side seating rather than the tandem arrangement seen in both the first 1-litre car presented in 2002 and the L1 presented in 2009. In the new XL1, wing doors make it easier to enter and exit the car. Further progress has been made by manufacturing body parts from carbon fibre reinforced polymer parts (CFRP), a technique used in Formula 1 car construction. Once again, Volkswagen has successfully achieved significant reductions in production costs– an important step forward to make viable a limited production run of the XL1. Background: together with suppliers, Volkswagen has developed and patented a new system for CFRP production in what is known as the aRTM process (advanced Resin Transfer Moulding).

      i would drive it, looks cool!
        • 4 Years Ago
        Interesting, at least.
        • 4 Years Ago
        There's some Volvo-esque elements in here. I love it!
        • 4 Years Ago
        Leo, I was thinking the same thing. It looks like a concept car from 1989 predicting what cars in the year 2000 would look like.
        • 4 Years Ago
        Sorry but any wheel covering body panels is a major fail in my mind. I could care less about mpg, efficiency, etc, it just looks lame.
        • 4 Years Ago
        looks like something from the Demolition Man movie from 15 years ago

      i like the development of the horizontal VW corporate 'face' and headlights. The wy they incorporated them in to a single wraparound unit works really well. I think the way they flared the rear wheel opening and then covered it with a fender skirt is awkward. I think that's what contributes mightily to it's "otherworldly" appearance. Fender skirts when fared in smoothly can be a very elegant solution to the quest for great aero numbers, but when they're awkward, as here, they don't work at all.

      The styling is great, but a 2-cylinder TDI? Come on...
      I miss the 2000s...

      But VW has my appraise for the 260mpg, as a concept is astonishing.
      • 4 Years Ago
      I don't belive its possibel to go 100 km on 1 liter of gas, with a 2.0 tdi engine even if it's mated to an electric motor, maybe with a 0,7-1.0 l. engine with 2 or 3 cylinders, then maybe you can reach that number, but not with the 2.0 tdi 4 cylinder diesel, i just don't belive that.

      Honestly I think that this is a fantastic looking car but it is gonna be spendy.Hybrid is expensive, TDI is expensive, rear view cameras are expensive. I do love the simple interior. I am sure it will change inside a lot as all concept cars do. But I think this is one if the best looking cars The Vee Dub has ever shown. I have always considered their styling very conservative and well, boring. Very good, boring looking cars.

      I like this.... Honda Insight 2.0... or what it should have been.
      • 4 Years Ago
      this car is awesome looking! one major question: why is the rear window virtually eliminated (and notice NO side mirrors on the concept vehicle). its about time the auto industry took a major leap toward weaning the world off fossil fuels. add the gullwings, cool!
      • 4 Years Ago
      So how fast does it accelerate? 260mpg is nice, but if it goes 0-60 in 10 minutes, it's a deathtrap.
      • 4 Years Ago
      I registered for this site specifically to post this comment in case anyone from VW is prowling the boards.

      Build this and I will buy two for my family.
      • 4 Years Ago
      Nice. It looks a lot more practical than their other 1-liter concepts.
      While rather too exotic to make a dent in overall global emissions, it's great that a company is working on this visionary goal.
      • 4 Years Ago
      Do it. If VW builds this I will buy one for each of my family members.
      • 4 Years Ago
      I know it's easy to say this when the car isn't actually available, but I'd buy one in a heartbeat if I could. I like the thought of refueling once every 10 weeks or so.
