The team's goals were to reduce friction and improve the vehicle performance.
Building upon previous iterations of aerodynamic, low friction BYU supermileage vehicles, the team designed, fabricated, and tested a new gasoline powered engine to be used in an existing supermileage chassis. They also built a portable dynamometer for tuning the engine at the competition.
The team customized a Briggs and Stratton Junior 206 engine block to have a displacement volume of 54 cc and a 17:1 compression ratio. The small displacement volume decreased the amount of fuel required per engine cycle, while the high compression ratio maintained adequate power output. The dynamometer was built using a DC motor with variable applied resistance. The vehicle wiring was replaced and color coded for improved reliability and ease of use.
