Since we're comparing apples and oranges we tried for simple metrics which consumers have been already given (excepting BSFC ).
Engineers work with Btus and all energy/power relationships can be related to Btus,making the transition between talking about BEVs and ICEs more transparent by the relationship to brake horsepower/road load,which all vehicles share.
The EPA has provided the MPGe already.We're just expanding upon it.
On a Btu-to-Btu basis,the LEAF and BOLT both share a 0.1397 lbs per bhp-hr BSFC.
If your ICE car's engine and drivetrain were as efficient as that of the Bolt's powerplant/powertrain ,you could expect 3-X mpg from what you experience today.
That's all we're saying.All the caveats are mentioned in the preamble to the guts of the article.
