Fuel efficiency has finally moved to the forefront of many consumers' minds after 2008's record fuel price spike and demand is higher than ever for miser-mobiles. Several vehicles have benefited from the green car movement, and the Inside Line crew corralled three hybrids, a diesel and a supersized go-kart in the ultimate test of fuel economy prowess.

The Toyota Prius, Mini Cooper, Honda Insight, Ford Fusion and VW Jetta TDI were assembled to compete for the best fuel economy in city, highway and back road driving. IL also measured the cost to fuel each vehicle and the amount of CO2 each emitted during the test. The five vehicles were prepped to do battle, but ultimately it wasn't much of a fight.

The Toyota Prius won every conceivable category by a significant margin with amazingly similar fuel economy between 47 and 48 mpg in all driving tests. The Prius also took on all comers in regards to carbon emissions as the symbol of green motoring spewed .08 fewer pounds of pollutants during the test than the second place Honda Insight.
