93 octane gas is $3.50 near me. So that $7.20 would buy me 2.05 gallons of gas. Over 240 miles that's 117 mpg, or 4.6 times more efficient than my E46.

I think super charger rates are more like $0.25 / kwh. I mean, mine will be free, but even if it weren't, who cares? 99% of my charging will be done at home.
You should account for losses during charging if you want to be super precise, but yeah, that's the thing about these cars--they are more efficient.
