OK, these ridiculous mpg claims are starting to get out of hand. Earlier this week, General Motors announced an via Twitter) that its could do better:for the upcoming Volt extended-range EV--a claim that was later . No doubt attempting to steal a bit of GM's thunder, Nissan claimed (
"Nissan Leaf = 367 mpg, no tailpipe, and no gas required. Oh yeah, and it'll be affordable too!"
At first, we thought this was an odd claim to make, seeing that the Leaf is fully electric and (as stated in the same tweet) doesn't actually use gasoline or diesel fuel. Nissan, followed up later with another tweet stating that they were using a DOE formula to estimate the 367 mpg equivalency for the electric LEAF, but doesn't that just confuse prospective customers further with obtuse conversions?
What do you think, wise and noble reader? In a world where vehicles run on gasoline, diesel, hydrogen, ethanol, alcohol, natural gas, and electricity (to name a few), is it time for a new efficiency metric or should we stick with old faithful (if not sometimes inapplicable) miles per gallon?
