Sahimo Hydrogen Vehicle Gets Over 1,300 mpg

Mike writes "Students from Turkey's Sakarya University have unveiled a remarkable attempt at creating Europe's most fuel-efficient vehicle. Dubbed the Sahimo, their pint-sized hydrogen car is cable of eking out an incredible 568 km on 1 liter of fuel (about 1,336 miles per gallon). An aerodynamic carbon-fiber construction keeps the vehicle's weight down to less than 110 kg (243 lbs), and the designers hope to push the Sahimo's performance even further to a full 1,000 km per 1 liter of fuel before participating in the Global Green Challenge in October."

1,336 MPG

Still 1 short from being leet!

No, it's all good - true leet hackers start indexing at 0.

The real question

[AntiOrganic]

At 110 kilograms, how far will it fly when it gets T-boned by a Hummer?

Re:The real question

If you are referring to the first column in that table, it's a bogus comparison. Americans drive many more miles per year on average than Europeans, hence more chances to get killed. Second column "Road fatalities per 1 billion vehicle-km" is a better comparison and US figure very much in line with west European averages. An even better comparison would take into account the average speeds involved in the accidents as I bet US average speeds are higher (much wider roads on average and more highway driving as trips are generally over greater distances). Yes, I know about autobahns but still in general I think that's true.

Note: I live in the US and drive a small fuel efficient car so don't mistake me for an SUV lover, I just hate misleading statistics

Per liter, why is that hard?

[Rakishi]

I'm sure you can find some nice radioactive thermal generators that have under a liter of fuel in them. That will get you a hundred thousand miles per liter easily.

Gases are compressible. Gallon is a measure of volume. Theoretically, highly compressed hydrogen would give you liquid hydrogen. Hydrogen compressed occupies 3 times more volume than gasoline for the same energy. http://www.planetforlife.com/h2/h2swiss.html

Shell Eco Marathon, 1246 km on 1 liter

[skeffstone]

I'm surprised. Why does this 3rd place winner get this attention? If the numbers are anything to impress with, take a closer look at the winner, the Norwegian contribution, clocking in at 1246 km per 1 liter of fuel equivalents.

Re:Not a good measure

[skeffstone]

Again, for all participants in Shell Eco Marathon, including the Norwegian contribution, and the Turkish one, they are allowed to use the amount of energy in 1 liter of petroleum. The unit is not 1 liter of hydrogen, but 1 liter of gas. They use hydrogen which is consumed in fuel cells, but the amount of energy in that xxx volume hydrogen equals the amount of energy in 1 liter of gas. The efficiency of the whole system is reflected directly by how far they get with the fuel they are allowed to take on board the vehicle.

110 kilograms

[Futurepower(R)]

From the article: "The SAHMO is truly a lightweight carbon fiber vehicle, weighting less than 110 kilograms."

The entire car weighs less than an overweight American.

Re:110 kilograms

[Simon Brooke]

you're modded funny but what that means is that the incredible mileage of that car will be cut in half with one overweight passenger, and two people on it will make short of the mpg promises

The solution is easy. Make the land-whale run behind. Then you get incredible mileage and he loses weight!
