Not content to let General Motors grab all the shiny happy tree-huggy headlines today with its 230 mpg claim for the Chevy Volt in city operation, the gang manning the NissanEVs Twitter account needled GM's range-extended EV messiah, tweeting:
Given that the methodology of how the feds will ultimately arrive at the official mileage numbers (or mileage equivalents) for many of these next-gen greenmobiles is not yet finalized, we'll take all the hype and scoreboard pointing with a grain of salt until we see actual, final numbers posted at FuelEconomy.gov. (Nissan says its 367 mpg figure was derived by using the Department of Energy formula.)
In any case, a Twitter spitball fight between GMBlogs and NissanEVs over this stuff would be kind of entertaining to watch. Sorta like the nerdy opposite of the ZR1 vs. GT-R debate.
