What better place than the Motor City – Detroit, USA – for more than 1,000 students from Toronto to São Paulo, and many places in between, to roll up for the 10th Shell Eco-marathon Americas?

Running from April 22 to April 24, the event is a chance for nearly 130 teams of high school and college students across the Americas to showcase their own extra-energy-efficient, custom-built cars designed as much to captivate as to innovate.

All are pulling out all the stops to push the limits and innovate solutions to the world's most pressing mobility challenges, and win awards on and off the track. They still have an event best of 3,587 miles per gallon (1,525 km/l) as inspiration, set by Quebec's Université Laval in 2013.
