The World’s Most Fuel Efficient Car: VW’s 261 MPG XL1 is Here

Volkswagen XL1

At 261 MPG, the production version Volkswagen’s high-efficiency XL1 is nothing less than a supercar. It may not be super-fast, but its task is not conquering LeMans – its mission is to change the automotive landscape and establish a new standard in high-mpg commuting. The new VW XL1 does that, and looks for all the world like a streamlined hyper-exotic at the same time it’s behaving like what it is: the world’s most fuel efficient car (in series production, anyway).

Volkswagen’s new XL1 should look exotic, because it is – with lightweight material, engine, and chassis technology that rivals the high-dollar, high-horsepower rarities coming out of the Porsche and Ferrari factories. It’s more than that, though, as its fuel-efficiency figures (more than double those of my old 50 cc Metropolitan) testify to.

In true supercar fashion, most of the Volkswagen XL1 will be built by hand in VW’s Osnabrück factory, while the carbon fiber monocoque comes courtesy of a supplier in Austria (KTM?). The 800 cc engine is derived from the company’s 1.6 L diesel, though modified for smoothness and even more efficiency, and is good for 47 horsepower and 89 foot pounds of torque, with an additional boost up to 68 horsepower and 103 ft-lb from the hybrid electric motor available – enough for a 100 mph top speed and 0-60 runs in the 12-13 second range. Not good, but not totally awful (and plenty fast enough, given enough road, to land its less fuel-conscious drivers in some seriously hot legal waters).

You can get a sense of the car’s layout in the cutaway graphic, below …

… and, while I’ve clipped a few of my favorite pictures from Volkswagen’s press release, you should head on over to Jalopnik for high-res versions of ALL the XL1 photos until the official reveal of the VW XL1 – the most fuel efficient car in the world – at Geneva next month (true to VW’s promises, it should be noted). No word, yet, on pricing, but tech like this ain’t gonna be cheap.

Start saving now.

About Jo Borras

I've been working in motorsports and tuning since 1997, with some the biggest names in the business. In 2008, the work we did on a hybrid/EV concept car attracted the attention of Gas 2 editors, and they invited me to join the team. I couldn't resist!

    It’s not going to get over 120MPG in real world driving. 261MPG is like saying the Volt will get 300MPGe (remember that?). 
    The XL1 uses a 0.8L engine with hybrid assistance. A 1.2L Polo Bluemotion gets way less than 100MPG on average (US gallons).

    I can’t imagine a car getting that many miles per gallon of fuel, real-world or otherwise. Unless part of that has to do with the fact that most of the driving is done using the electric motor during cruising.

    The XL1 is rated at 261MPG in the European test cycle. That
    would equate to 235MPG in US gallons. And since diesel contains about
    20% more energy per gallon than gasoline (E10?), if it burned gasoline
    that would be ~188MPG. Still, very impressive!

    I’ll take the ~31 miles of all-electric range – the total battery pack
    size is reported to be 5kWh and assuming (never a good thing?) that they
    are using 90-92% of that, that means the XL1 is about 145-150Wh/mile.
    Which not surprisingly is a little bit better than the EV1 – and almost
    entirely proportional to the Cd’s of each car. The EV1 in production
    had a Cd of ~0.20 and the Cd of the XL1 is just under 0.19.

    There is at least one report that VW will be using (a front wheel drive
    version of) the XL1 drivetrain in the Up! This would be a lot less
    expensive, and much more practical, and the Up! is only 300 pounds
    heavier than the XL1. The Cd would be the biggest change – the Up! is
    probably 50% higher Cd and probably close to 100% higher CdA.

    This is interesting:

    I hope that this is referring to the Up! Lite – but if it is the Up!, then that is okay, too.  Here’s the Up! Lite:
