Regulations

Official Interpretations

Please submit all questions regarding the regulations to ascregs@americansolarchallenge.org. Official interpretation of the race regulations will be posted here.

Question: We have been told that composites above the occupants’ shoulder-line in the structural chassis cannot be included in our analysis of the impact load cases outlined in Regulations 10.3.A.8 as load bearing panels in the own right, or as mounting points for our metal roll cage. We are asking for an official interpretation of the regulations under 10.3.

ASC Response: Regulation 10.3.A.1 defines the roll cage as the structure that encompases the occupants from the shoulder up. Therefore, any structure above the shoulder is considered to be part of the roll cage and shall be metal, not composite, per regulation 10.3.A.4.
