# French MicroJoule concept car gets 8,923 miles per gallon

Lennergy, How do you compress the air? This in itself is not a very efficient process.

This is fantastic but, why not use cars only driven by Compressed Air? This car´s exist, www.AirCar... The best Leo Mac Ender

The Microjoule is your answer, getting over 3,794 kilometers per liter, or approximately 8,923 miles per gallon! Looking less like a car than an amoeba-on-wheels, the Microjoule is the design of students from the French Technical School, St. Joseph La Joliverie, who are set to compete in the Eco-Marathon 2008 to be held in Europe this coming May.

The site really appeals to me! I have to register!

Hey Guys!, we plucked the number from the Microjoule's page, which says that "Le record du monde battu à 6 reprises dont le dernier à 3794km parcourus avec 1 litre d'essence." Using my rather rudimentary skills of french, this translates to "Six-time world record holder, the last time achieving 3794km per 1 litre of fuel" Being an architect, thus terrible at math, I say that: 3794 km/l * 0.62m/km/l (approx) = 2353mi/l * 3.792/gallon= 8923 mi/gallon (approx) So obviously Wired got it from the Shell Eco Marathon results of last year, while we got their figures, so they are different... but, as stins says, much better than 25mpg Thanks for keeping us honest though :)

I read on a couple other posts that it got closer to 7,000 MPG: http://www.ecogeek.org/content/view/1446/69/ http://www.treehugger.com/files/2008/03/french_car_gets_7150_mpg.php Either way...it sure beats my 25 MPG car...

I've read other posts about it that report numbers closer to 7,000: http://www.ecogeek.org/content/view/1446/69/ http://ecomodder.com/blog/2008/03/15/super-mileage-competition-nets-7148-mpg/ http://www.treehugger.com/files/2008/03/french_car_gets_7150_mpg.php Either way...it's sure better than my 25 MPG car...

Ummm.... someone has the maths wrong. One story says the "mileage" was 7150 miles/gallon, and another one says it was 3794 km/litre. These two values aren't the same, though. 3794 km/l = 2357 mi/l = 8924 mi/gallon 7150 mi/gallon = 1889 mi/l = 3040 km/l There seems to be a discontinuity in the maths (or in the reporting).
