Mater Dei High School Supermileage Team

Great success for the team. Team Cosmo finished in second place in the Prototype - Internal Combustion category. Team RUDI defended their winning streak for a 10th year with a new track record of 140.2 miles/kilowatt hour.

The team also won a spot to go to the World Championship in 2027. Details to come. Only four teams from this competition were selected.

Edit: 4 from 72 teams from 52 institutions!

RUDI has extended his lead with a new car record of 125.4 miles/Kilowatt hour. We believe this is also a new Shell Americas Urban Concept Battery Electric record.

RUDI has reclaimed first place in his category, but only by 2Kwh/mile. Meanwhile, Cosmo has broken the 2,000mpg for the first time since the mandated change to fuel injection over 9 years ago.

Our first round of competition runs didn’t go as hoped with the wind taking the hatch cover off Cosmo resulting in a DQ run and RUDI suffering a slow tire leak. RUDI is in second place currently with the hopes of taking the lead today. Check out this link for a nice local story on the event and a bit of an interview they did with our Team Cosmo student leader.
