What, you expected the "fastest muscle car ever" to help fleetwide fuel economy? Nope, don't think that's going to happen. That means Fiat Chrysler will likely to continue to languish at the bottom of the heap when it comes to fleetwide fuel economy among the largest automakers serving the US, especially as the automaker starts to sell its Dodge Challenger SRT Hellcat.

Zoom-Zoom, indeed. Toyota may be the world's biggest maker of hybrids and Nissan may be making big strides on the plug-in front with increased sales of its Nissan Leaf electric vehicle, but it's Japanese automaker Mazda that has once again topped the Environmental Protection Agency's (EPA) list of most fuel-efficient automakers selling vehicles in the US, increasing its Model Year 2012 average by half a mile per gallon compared to MY2011.
