Houston, Texas – For the third consecutive year, students at Quebec’s Universite Laval have won the Shell Eco-marathon Americas fuel economy challenge, defeating 62 teams from across the U.S. and Canada at the two-day street course challenge in Houston.

The challenge requires students to design, build and test fuel-efficient vehicles that travel the farthest distance using the least amount of energy.

The Universite Laval team won the Internal Combustion First Prize in the Prototype class, achieving a best run of 2,564.8 miles per gallon, an improvement of 77 mpg over last year’s mileage. In the Urban Concept class, a team from Louisiana Technical University in Ruston, Louisiana took the top prize by achieving a best rest of 646.7 mpg. A full list of winners is available at Eco-marathon.

The 2011 edition saw a record 62 student teams competing with 68 vehicles. The vehicles, which compete in either Prototype or Urban Concept classes, can be powered by a variety of fuels, including gasoline, diesel, biofuels, electricity, hydrogen or solar power.
