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
