A team of students from Mississippi State University (MSU) have placed first in the "Challenge X: Crossover to Sustainable Mobility" competition, in which 18 universities re-engineered a 2005 Chevrolet Equinox to increase its fuel economy while reducing its environmental impact. To win the competition, the Mississippi State team designed a hybrid electric system powered by a 1.9-liter direct-injection turbocharged diesel engine and fueled with B20, a blend of 20% biodiesel and 80% diesel fuel. The resulting vehicle achieved a 48% increase in fuel economy over the standard production vehicle. This was the third and final year for the Challenge X competition, for which DOE and General Motors Corporation were the lead sponsors.

Meanwhile, the Rose-Hulman Institute of Technology has won the collegiate division of the Supermileage competition, sponsored by the Society of Automotive Engineers. The competition involves the design and construction of a single-person, fuel-efficient vehicle using a four-cycle Briggs & Stratton engine. Rose-Hulman achieved 1,541 miles per gallon (mpg) with its vehicle, far short of the record 3,145 mpg for the competition, which was set last year by the University of British Columbia. Rose-Hulman also fell short of the 1,693 mpg achieved in the high school division by Mater Dei High School of Evansville, Indiana. Mater Dei has won its division for four years in a row.
