TED-Ed: This is what happens when you hit the gas | Shannon Odell

In 2015, two men drove a Volkswagen across the US on just over 100 gallons of fuel. Their 81-mile-per-gallon performance doubled the car's estimated fuel rating, and set the record for the lowest fuel consumption ride of a diesel car. The duo were experts in techniques that maximize fuel efficiency. So, how did their strategy save fuel? Shannon Odell explores what's going on beneath a car's hood.
