Hyundai to get half of MPG improvement from powertrains {Autoblog Green}
May 6th 2008 11:12AM Is the 50% of the improvement from powertrains BEFORE or AFTER the other end-use improvements (Aero, Lightweighting, Rolling Resistance - components of the actual road load equation)?
It's more efficient to reduce the engine loads in order to reduce the size of the engine. A smaller engine producing similar performance on a lighter, less draggier car will use less fuel [simple!].
U.S. Transportation Secretary wants to drop gas taxes in favor of tolls {Autoblog Green}

No, the gov't shouldn't tell us which cars to buy, but the Big 3 just don't know how to make a product that the mass public doesn't know to choose. Offering up a new more efficient model for the hell of it never was their style - I believe the case is clear that the gov't CAN help efficiency happen [at least quicker].
Also, 18 cents/gal => $2 to $4 per tank .... maybe a few hundred a year might make a difference (similar to savings with the prius).
