How can hypermiling save you gas?

Josh and Chuck dive into the surprisingly complex world of gas mileage calculations, exploring why the EPA's fuel efficiency ratings on car stickers rarely match what drivers actually experience on the road. They break down the testing methods used by automakers and the EPA, from laboratory dynamometers to tailpipe sensors, and explain how real-world factors like weather, traffic, and driving habits create such dramatic differences. The hosts also explore the fascinating world of "hypermiling" - techniques used by ultra-efficient drivers to squeeze every possible mile out of a gallon of gas.
