From about 1975 through 1987, federal standards prompted massive and surprisingly rapid improvements in fuel economy. Cars designers focused on nimbleness and efficiency over raw power, and the fuel savings were enormous.But since the late 1980s, most engineering advances have focused on making cars more muscular, and fuel efficiency has taken a b ...

Plug-in hybrids rule; PHEV Hypercars rule even more Let's go all the way	Gar Lipow	26 Jul 2007	Gristmill
When David pointed out that plug-in electric hybrids (PHEVs) can reduce carbon emissions in all possible futures, two main arguments were raised in opposition -- practicality, and the possibility that they will provide too low a reduction, while blocking the path to something better.
