Calling it a car does not make it a car. 3 wheels and space for one passenger makes it closer to a Can-Am Spyder Motorcycle.

Correct me if I'm wrong, but isn't moving the same distance using less fuel cleaner?

#23This is pretty cool. But at what speed did the car travel that many miles?

#24A nice engineering project, sure. But it has nothing to do with cars. They only thing that their results show is that you can get vastly different results for vastly different constraints and requirements.

These types of articles gloss over what the researchers are trying to perform. To say its a "car" is an exaggeration. They are basically piston engine prototype vehicles. They are testing the limits of piston engine fuel efficiency and that is their main and only objective.
The driving strategy is very different to normal car driving. They do a lot of pulse throttle acceleration where they tap the gas and then coast for as long as possible. They also drive very, very slowly to minimize wind resistance. The idea is to test conditions to optimize fuel efficiency and not for practical every day driving.
That said there is a lot of benefit to the research. They are testing which conditions work best for fuel efficiency in all sorts of designs from engine performance to vehicle body.
Here is a great site to look at DIY improvements to help with fuel efficiency. http://www.ecomodder.com

#26Very cool car, very poor quality article. It reads like it was written by a syndication algorithm that throws in weirdly subjective statements at the end of every paragraph. Here's a slightly better one with a video: http://wonderfulengineering.com/new-car-designed-by-french-s...
I assumed it was written by someone not using their first language and found it endearing as a result. Have to admit that wondering if it's written by an algorithm gives me an opposite reaction.
Definitely a translation, or written by a non-native English speaker. Things like using a comma as a decimal (0,03 liters) are a pretty big giveaway.
I think what threw me the most was how SI and US units were mixed right in the title (liters and miles).
Flipping through the rest of the site, it does unfortunately read like they're just churning out content to draw search traffic primarily for advertising.

Your too generous, its not a car. It is a rolling science project, a trike, something no one could drive to work or play. I want to see work done with existing vehicles, full safety and comfort features, where through inexpensive aerodynamic changes and propulsion tricks improve on what manufacturers offer now.
Thanks for posting this. My own first thoughts on seeing the project were: looks like a soapbox racer (and I laughed watching a video where they gave it a manual push down a slope to get it going), does France not have speed bumps or steep driveways or road litter, what's its top speed, and how survivable is a collision? This competition is just pure PR for Shell and other companies, engineering constraints for an ac…
Speed bumps would be prohibitive for F1 too. Yet, many technologies perfected in F1 made their ways into every day cars.
This is a race car. The purpose of the race is not to be the fastest but to consume the least amount of petrol.

> And why describe fuel economy in miles per liter? err, why not?
The most common fuel efficiency ratios are expressed either in miles per gallon or kilometers per liter (or liters per 100 km). Mixing imperial and metric units is pretty unusual.
This is a bit of clue that the article is written by a non-technical writer, or the editor is also sloppy.

Ha. Its not even a car - it's a tricycle[1] ! The distinctin may sound pedantic but legally speaking they are quite distinct: It’s lack of a four wheel, and low production volume, exempt the Morgan from most safety and emissions regulations. At least in the US...Quite Ironic.

Depends. If you have to build a new car to do it, the answer is almost certainly no.
