Northview High School student Alex Montgomery answers questions about Indiana's Super Mileage Challenge high school competition. Last year, the NHS students achieved 391 miles per gallon, moving no faster than 35 mph at Indianapolis Raceway Park. Again, this year, they will enter two vehicles, modified and unmodified versions. Their goal is to get 500 mpg. The vehicles are powered by pull-start 3.5 horsepower Briggs & Stratton gas engines. The driver has to start and stop the engine as the vehicle moves around the track. Students need donations to build the vehicles. Montgomery addressed the Brazil Rotary Club at Smokin' Charlie's Come and Get it Diner, Knightsville, Wednesday.
