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....
