The Little Battery that Could

I drove the Prime 215 miles today, mostly with A/C on during a 90F day

150 mpg ! My cost: $4 of petrol
6.2+6.2+4.2+4.6 = 21.2 kWh from the meter. My cost: 30 cents of electricity
Total cost per mile: 2 cents

That is just crazy good efficiency. If I figure 4.7 miles/kWh from the meter then
158 MPGe for the EV miles and
77 MPG for the HV miles

I started out with a full charge;
Next town over I took a break to stretch and catch on on emails while I plugged in
At noon I stopped to eat and charge
At home I recharged during the 3 hours I had before heading out again
