And here I thought 1,902.7 mpg was a lot. That was the winning rating at last year's Shell Eco-Marathon Americas coutresy of Cal Poly, San Luis Obispo. This year, three teams had a higher mpg score in the event this weekend, and it was the students from Mater Dei High School from Evansville, Indiana who coasted away winners with a mpg rating of 2,843.4 in their #22 vehicle (on the right side in the image above). Mater Dei's second vehicle (#21, on the left) came in third overall. Teams from both universities and high schools competed and Mater Dei took home the $10,000 grand prize.
As you can see in the list of teams that competed in the event, combustion engines far outnumbered other powerplants (six fuel cell, one LPG, one diesel, and two solar cars also competed) and, indeed, Mater Dei's #22 was a combustion-engine prototype vehicle. Details on the top results from the alternative powerplants are available after the jump, but here are the numbers: diesel got 304.5 mpg, LPG made 163.5 mpg, fuel cell/hydrogen made 1,668.3 mpg and solar got 2,861.8 mpg. That higher mpg number wasn't enough to win the competition because fuel economy wasn't the only category that counted toward the final score.

Student-Built Prototype Vehicle Breaks Mileage Record at 2008 Shell Eco-Marathon(TM) Americas
Mater Dei's 2,843.4 mpg achievement stretches boundaries of fuel efficiency
HOUSTON, April 13 /PRNewswire/ -- "Ladies and gentlemen, start your fuel-efficient engines" were the words that kicked off the 2008 Shell Eco-marathon(TM) Americas; and that's exactly what more than 300 students from Canada, Mexico, and the United States did today. Mater Dei High School of Evansville, Ind., set a new mileage record at the 2008 Shell Eco-marathon Americas, a challenge to design, build and test fuel-efficient prototype vehicles that travel the farthest distance using the least amount of fuel.
The team's combustion-engine prototype vehicle achieved an astonishing 2,843.4 miles per gallon, equivalent to 1,208.6 kilometers per liter. Despite wind gusts of up to 50 miles per hour and various teams' mechanical issues, competition was steep this year with three teams breaking the 2007 mileage record set by Cal Poly, San Luis Obispo.
"When we first arrived, I wasn't sure a small high school like Mater Dei could compete with all these elite colleges," said Justin Stute, Mater Dei High School team captain. "But our first run broke the record and then our second car did even better. That really motivated both of our teams to go all the way."
Mark Singer, global project manager for the Shell Eco-marathon said, "Students participating in this competition are the brains of the future, stretching the boundaries of fuel efficiency and providing solutions to the global energy challenge. Throughout the two-day competition, teams are constantly making improvements to their vehicles, exchanging ideas and inspiring one another to pay attention to their own energy footprint."
The 2008 Shell Eco-marathon Americas welcomed 32 teams from four high schools and 23 universities from Canada, Mexico and the U.S. The entries include 25 vehicles powered by combustion engines, four by fuel cell/hydrogen technology, one by diesel fuel, one by LPG (liquid petroleum gas) and two by solar power.
Category winners for the 2008 Shell Eco-marathon Americas include:
Grand Prize
With mileage of 2,843.4 mpg (1,208.6 kilometers per liter) the Supermileage Team from Mater Dei High School in Evansville, Ind. won a $10,000 grand prize with their vehicle, 6th Gen.
Combustion Engine
The 6th Gen vehicle from Mater Dei High School in Evansville, Ind., took first place in this category with its 2,843.4 mpg (1,208.6 kilometers per liter) run.
Diesel
Eureka, Calif., based Diesel Corsair team placed first. The College of the Redwoods team achieved 304.5 mpg (129.4 kilometers per liter).
LPG (Liquid Petroleum Gasoline)
The Spartans from Schurr High School in Montebello, Calif., achieved 163.5 mpg (69.5 kilometers per liter) in their Mach 1 prototype vehicle.
Fuel Cell/Hydrogen
Penn State's HFV Team from University Park, Pa., achieved 1,668.3 mpg (709.1 kilometers per liter) in its Blood, Sweat and Gears vehicle.
Solar
The Purdue Solar Racing team from West Lafayette, Ind., took first place with its solar vehicle Pulsar, which achieved 2,861.8 mpg (1,216.4 kilometers per liter).
Mileage wasn't the only challenge
Achieving the best fuel economy in a category isn't the only win. Addressing challenges on and off the track and turning them into successes through teamwork and innovation is also a victory for student teams. Months of planning helped teams stretch the boundaries of fuel efficiency.
The weather conditions created challenges for students and required one team to switch to a heavier driver, which resulted in a vehicle redesign.
"We designed a car for a special driver but when we entered into the track at first, we had to change drivers," explained Eugenio Martin, a student from the Universidad Nacional Autonoma De Mexico (UNAM). "Once the car was modified for the other driver, we had transmission problems. It is the biggest success for us, and it's the greatest feeling because we fixed the transmission problem in one and a half hours."
While the team from Mexico was working through their technical issues, the 17-member team from Universite Laval was on hold for two days waiting for their vehicle to clear U.S. customs. With only one day left to compete, the Canadian team worked well into the night to fully assemble their car and clear inspection within 12 hours. In their first attempt, the team from Quebec moved into fifth place.
"It was a nice outcome that we got the car," Raphael Desiletes-Aube said. "We used the spare time to organize the fastest way to reassemble the vehicle. Once the car got here, it really motivated my team members to push harder so we could get the car out on the track."
Real World Experience
The event also allowed students to gain practical experience by applying concepts taught in the classroom. While designing and financing the vehicle is done before students get to track, teams are constantly making modifications to improve vehicle performance.
Students like Shane Stoterau, a student from Northern Arizona University, said "At NAU, we don't have a lot of hands-on engineering where you actually take something from paper and put it into implementation. So it's actually nice to see where we take a design, fabricate it, and actually run it."
Grand Rapids Technical School student Hillary Ropponen agrees, "I think Shell hosting this event is awesome. For one thing, it helps kids like us from high school learn about engineering, learn how to design things. And then it promotes a lot of the eco-friendly stuff that people care a lot about these days."
Shell Oil Company, including its consolidated companies and its share in equity companies, is one of America's leading oil and natural gas producers, natural gas marketers, gasoline marketers and petrochemical manufacturers. Shell, a leading oil and gas producer in the deepwater Gulf of Mexico, is a recognized pioneer in oil and gas exploration and production technology. Shell Oil Company is an affiliate of the Shell Group, a global group of energy and petrochemical companies, employing approximately 112,000 people and operating in more than 130 countries and territories.

As outlandish as these vehicles look, they probably will have more in common with tomorrow's cars than will an F1 racer.

How can you measure solar cars in MPG?

The solar cars use joule meters that measure the energy consumed by the motor during a run. This is then converted to the equivalent mpg.

Just skimming the article, I didn't see numbers for speed or duration of runs. That's a huge factor for real world application.
Still, impressive.

‘ Breaks mileage record’ ?? what utter nonsense.
The current world record for fuel economy was set on July 9, 2003. by a french team called Microjoule with 10,705 miles per gallon (approx. 9,020 miles per US gallon)
I have been involved in these vehicles in the UK over the past 25 years and we were achieving ~2,500mpg back in the early '80's without fuel injection.
This shows how america is 25 years behind Europe with environmental issues.
Not to mention really bad reporting and ignorance of anything outside of 'the states'

The cars has to complete 7 laps around a 1.4 mile road course in 38min 50sec, which works out to an average speeed of about 15mph.
The record the article referrs to is the US record set by CalPoly in last year's Eco-marathon; the press release doesn't really clarify that.

"As outlandish as these vehicles look, they probably will have more in common with tomorrow's cars than will an F1 racer."
I.e., Aptera. :) Compare an Aptera:
http://www.fuel-efficient-vehicles.org/energy-news/wp-content/uploads/aptera-230mpg-hybrid-car-3.jpg
With this eco-racer:
http://www-static.shell.com/static/at-de/images/at_de_2005/PAC_CarII_2005.jpg
Of course, you see the problems with commercializing these eco-racers as-is. They're not stable enough for high speeds (hence Aptera's need to broaden the front wheelbase, increasing the drag coeff, as well as wider tires for better handling), there's too much ground turbulence at high speeds (hence the higher body), they're not comfortable for passengers (hence the larger cross section), and they're not streetlegal (hence things like the truncated, not-completely-tapered tail). Also, there's the fact that by their very nature, things like "normal driving cycles" and "highway speeds" greatly increase drag. And all of this adds weight, too. Hence, "thousands of miles per gallon" turns into "130 miles per gallon" (in the Typ-1h). Still impressive, mind you.

Why can't this technology be passed along to some degree to the market for production so that the consumer can get a car that does better then 33mpg that so many automakers brag about. Why is it that we still have to drive cars who's MPG has barely increased in the last 30 years? Is it because the Big Oil and Gas companies are afraide we won't be so dependent on gas anymore? Pure supply and demand. If the demand decreases, the supply increases, and the price decreases. Therein lies the answer.

Daniel, America is well aware that we are behind Europe and Asia in eco development, as evident by the grassroots efforts showcased in this story. You are not providing groundbreaking information, so you can stop patting yourself on the back. Your arrogance and ethnocentrism don't help matters, either.

That is an amazing achievement, not to mention that it was designed by high school kids. Kudos to the Mater Dei High School speed-racing & eco-saving vehicle design team.

These prototypes really don't matter. When they can tout a sufficient mileage carrying a weight of 2000 pounds or more then I'll be impressed.
Not to say what they've done isn't note-worthy. However, these tests are a long way from creating a viable transporter that can carry a family of 5 any distance that is required for today's needs.

By the time you hang all the stuff on it to make it legal - bumpers, safety glass, real tires, lights, etc., you will have a 1 person vehicle with no room for groceries, a little better mileage than a regular car, and a top speed that will leave little old ladies passing them on their bicycles. Might as well buy a motorized wheelchair & plug it in overnight. Is this how Shell justifies their tax credits?

How can you carpool when your car can only fit one? Where's the Satelite radio, air conditioning, a place to plug in the I-Pod, all those things we have grown accustom to. Instead of wasting time with go-carts that will never see the road, try building a family car that will fit everything the average family needs to bring with them and then see in you can get 2-3000 mpg. If I stripped my car down to the frame, I would be getting a lot better gas mileage too. Also build your go-cart to the federal highway safety regulations as well!

It is extremely exciting to see these young people work together to produce such results. It really goes to show that we have a great number of young people who are able and ready to take on the challenges of this universe.I now feel a real ray of hope for the next generation.
Congratulations to all involved, especially the sponsors,teachers,parents and all others involved.
My hat off to all the young drivers and mechanics. As a psychiatrist, this feels wonderfully refreshing to see such progress by young people.
Great job,
DrMarion Dunn

I can see daniel billinton's point of view. But on the other hand i also can see the amazing acheivement of the Mater Dei High School students. we have to remember that these aren't fully grown people. for 16-19 year old minors to be pumping out this kind of eco-friendly methods of transportation is incredible. Just imagine what these kids will be doing in the future. Congratulations to all the young people who participated in this event. And i thank all of the parents, sponsers, and all of their supporters for helping these kids go through with this.

thats the info in the team microjoule's shell eco marathon euro winner... man we(the us) need to get on the ball! but then again if we were paying the $5+ they pay over there there would be more pressure to build more fuel efficient cars... 35 mpg is what old non fuel injected 80's cars would get. our technology should have more cars in the 40-50 range by now...
