The team from Cal Poly in San Luis Obispo, California, won the 2007 Shell Eco-Marathon. The team's vehicle (shown above) recorded a best of 1,902.7 mpg to win the Grand Prize and the first in the Combustion Engine Group. Next was Rose-Hulman Institute of Technology from Terre Haute, Indiana, with a reading of 1,637.2 mpg followed by Mater Dei High School of Evansville, Indiana, at 1,596 mpg. In the Hydrogen Group, Los Altos Academy of Engineering from Hacienda Heights, California, came in a 1,038 mpg.

The event was held at a windy and noisy (gas-guzzling stock cars were also testing on the main track) California Speedway in Fontana, California, on Saturday. Teams from across the U.S. were comprised of about eight students to build prototype vehicles with three or four wheels. There were 18 conventional-fuel fuels and one each in the hydrogen and solar categories.

AutoblogGreen was at the track Saturday for a technology seminar sponsored by Shell. We dropped by the Eco-Marathon pits and track for a few photos that can be viewed in the gallery. We'll have stories and interviews from the tech briefings later in the week.
