THE ONLY CANADIAN CAR IN THE RUNNING, ESTEBAN VI CROSSES THE FINISH LINE OF THE AMERICAN SOLAR CHALLENGE
Eight-day, 2,575-km race across eight American states, and a unique adventure to share!
For the first time in its history, the Esteban prototype, a solar-powered vehicle entirely designed and built by
Polytechnique Montréal students alongside their engineering studies, qualified at the Formula Sun Grand Prix. This allowed it
to then take part in the American Solar Challenge, the solar-powered vehicle race with the most stringent selection criteria in
the world. Esteban VI ranked in 9th position of the 11 vehicles that qualified for the race, ahead of MIT and New Paltz.
Sixteen university teams took part.
Led by Laurence Lebel, the Polytechnique team drove more than 2,575 kilometres on board its solar race car, from Rochester,
N.Y. to Saint Paul, Minn., over the eight days of the competition, which ran from July 14 to 21 across eight American states.
The Canadian delegation also won the award for best teamwork and the award for strongest solar panel power, in a tie with the
winning team from the University of Michigan. On July 12, the Polytechnique team notched a major success in the qualifying
round, completing 109 laps (105 were mandatory).
The students had to demonstrate great ingenuity during the competition, as they were facing American teams with much larger
budgets than their own. The delegation hit several snags along the route. First, the end of a wheel axle broke during the
qualifying rounds, because of wear and tear. The team was able to replace it using equipment provided by four other
universities, which were very generous with their materials and time! The fairings for the front wheels – the envelopes
in which the wheels are located – were also damaged, which greatly reduced the car's aerodynamic capacity.
“We dealt with a lot of bad weather. The clouds forced us to slow down so we wouldn't drain the battery, and rain caused
us to come to a full halt for a few hours in order not to risk skidding or losing control,” said Gabriel Brassard,
Finance Manager, upon his return from the competition. Also, the car was much heavier than those of the other top teams, and so
had to be revisited. The battery safety system was too sensitive, and cut the current when it was well below overheating
temperature. A few all-nighters later, and the problem was solved.
The team is now evaluating the possibility of competing in the Green Global Challenge in fall 2013 in Australia. With the
announcement of a number of changes in construction standards, the solar vehicle will require several modifications. The
engine, which dates to 1998, is clearly a priority, since it has lost a significant percentage of its efficiency with time,
which explains in good part the difference in performance with the race winners, despite having more efficient solar panels.
The construction of the next prototype will get underway starting late next month.
