http://www.economist.com/blogs/babbage/2012/04/electric-cars?fsrc=nlw|newe|4-20-2012|1447248|36350411| I've only skimmed this article but this author has a lot of his facts wrong and is mixing various random mileage tests and figures. Sigh... I think part of it is a side effect of the author not understanding CAFE mileage vs. Monroney sticker numbers and then falling into the trap of high sounding highway mileage numbers of various non-hybrids. The 27 mpg the UCS chose appears to based on combined EPA mileage. For him to make claims that "the average today is more like 35mpg" is bogus as per Fuel Economy, there are virtually no non-hybrids that achieve even 35+ mpg combined for the '12-'13 model years. Even the Smart ForTwo he mentions is rated at only 35-36 mpg combined and doesn't achieve 40 mpg on the EPA highway test. His claims about the Focus are wrong too: Per http://www.fueleconomy.gov/feg/sbs.htm, the '12 Focus is EPA rated at 31 mpg combined and the SFE version is rated at 33 mpg combined. It's funny how he claims the regular Focus "averages around 40mpg" (NOT) and mentions the Consumer Reports 44 mpg result for the Prius (which is a bit low). Well, the two Focuses that CR tested received 28 mpg overall per https://www.consumerreports.org/cro...-fuel-economy/best-and-worst-fuel-economy.htm. Feel free to chime in on the comments there and set this guy straight (hopefully).
