Dawn Treader (1997)

Dawn Treader is the team’s fifth generation car and was built to compete in four races. The World Solar Challenge 1996 was the main competition for Dawn Treader and its design was optimized for this race. The car was based on the proven design of Quest, the team’s fourth car. All of the major systems were modified or redesigned in hopes of making an already successful design better. This resulted in an eleventh place finish in Australia, the top North American showing and highest Canadian finish ever at this event. Following this success with a tenth place finish at Sunrayce ’97, despite a sub-par array, established the team as one of the top in North America.
