With all the ecological concerns we are facing lately, let’s watch a documentary made by the people who knows best about ecology: Top Gear. This episode will present the ‘one gallon fuel crisis race’: quite self explanatory, each Supercar will start with only one gallon fuel and will race around their track, the winner would be the last one able to drive. At the end of this episode, they made a fuel consumption comparison between a BMW M3 and a Toyota Prius, don’t skip that part: the result will surprise you.
