ShellHouston, Texas – A student team from Quebec’s Laval University has won the Shell Eco-marathon Americas challenge for the second year in a row. The team overcame vehicle problems that plagued them throughout the weekend, finally turning in ten ultra-efficient laps that took them to first place.

Their vehicle achieved 0.095 L/100 km (2,487.5 mpgUS), taking both the Prototype category and the overall crown. Their winning vehicle in 2009 achieved 2,757.1 mpgUS. A team from Indiana took top prize in the Urban Concept category for the second year in a row, achieving 0.538 L/100 km (437.2 mpgUS).

Held for the first time on a street course instead of a racetrack, the event involved 48 vehicles, including six teams from Canada. The teams could use any conventionally available energy source, including diesel, gasoline, liquid petroleum gas, hydrogen, biomass or solar.

The Laval team, which used a combustion engine, took home a grand prize of US$5,000.
