I thought we should have a little competition. Which is the most fuel efficient car in the world? Post your candidate and win!

The winner will be presented with the honor of maybe helping someone choosing a better car.

The rules are:

* The car must have been in production for quite some time. At least 5000 units have to have been built.

* The car must have 4 wheels and seat at least 4 people.

* Lowest mpg and CO2 emissions win.

* You must post a picture.



I'll begin. My candidate is the Audi A2 1,2 TDI 3L.



Fuel: diesel
Mileage: 95 miles per gallon (edit, this is US gallon. It gets 80 miles per Imperial gallon (sheesh, I didn't even know you insane people had two kinds of gallons, what the Hell is wrong with metric?!)).
CO2 emissions: 81 grams per km

175.000 units were produced between 2001 and 2005 when production was discontinued due to weak sales.

The original price in Sweden equaled $25.000, used cars cost approximately $15.000 at the present.

edit: I might add the abysmal acceleration.

0-60 mph in 15 seconds.

52 miles per gallon with no breakdowns, after 130,000 miles 3 cylinder.

exhaust doesn't smell and it starts in -20 degree temp without a plugin for those days when the grid is down.

Good acceleration, it is very light front wheel drive and travels on ica and snow very well indeed.

I'd go for the A2, also, but note that Audi doesn't advertise it as efficient as you mention.

I can't find it right now, but the specs they quote on their site are in the 60-70 mpg range (translated from the l/100km spec)

[Starvid]

It's 3,0 liters per 100 km mixed driving. Anyone interested can translate this to US miles and gallons. Hopefully it will end up 95 mpg.

[Starvid]

I crunched the umbers using a formula from this page and got 78 miles per US gallon or 94 miles per Imperial gallon. The earlier numbers were probably erroneuos due to a gallon variety mix up.

Still, 78 mpg is pretty impressive, no?

[Caoimhan]

Google has a handy units conversion function.

In the Google search bar, just type:

"3.0 l/100km to mpg"

This is REALLY handy. Let's do a torque conversion...

"150 newton meters to pound feet"

Cool, huh?

You've pretty much hit it spot on with the Audi as it is.

But if you changed your production criteria, I could have thrown in some midsize and luxury size pure electric cars, that well to wheels, get much better efficiency. If you changed your production criteria, I could have also thrown in prototypes like the GM Precept(90 miles per U.S. gallon, 0-60 mph in 11 seconds, full size car, .19 drag coefficient), or a Daihatsu concept that seats four, tops 100 mph, and gets over 150 mpg.
