CMR 57 set out to be a complete redesign of its predecessor, CMR 39. Nearly every system was polished and integrated more efficiently, leading to a much lighter and competitive car. After a long year of work and for the first time in several years, CMR finished endurance at competition! Now with a fully functioning vehicle many more tests can be completed to collect data for future design iterations.
