Not a bad review, but
Not a bad review, but everyone here is making the same mistake regarding fuel mileage. The volt calculated lifetime fuel mileage is fictitious. They calculate the fuel mileage by dividing the number of miles you have driven by the amount of gasoline you have used. If the Volt were a pure gasoline engine vehicle or a gasoline only hybrid like the Prius the calculation would make sense. However, if you use that calculation you are ignoring the fact that the electricity is not free energy that somehow descends from heaven and infuses your car with its holiness. If you want to calculate your MPGe while in electric mode, divide the number of miles driven by the energy used (in kWh), and multiply that by 33.7kWh/1gallon (the energy contained in a gallon of gasoline). The EPA uses an estimate of 36kWh per 100 miles which yields the 94MPGe. The calculation is shown at this point in a youtube video http://www.youtube.com/watch?v=zYbQDHdgvdY&feature=player_detailpage#t=64s. On a recent trip I drove 51.8 miles on 12.5 kWh (had a partial charge which extended the range of electric only travel), which calculates 51.8/12.5*33.7=139.6MPGe for that 51.8 miles, followed by 103 miles on 2.77 gallons for 37.2MPG. This results in a combined MPGe of 49.3, not 55.9 which would be the calculation based on the gasoline only (12.5/33.7=0.37 gallon equivalent+2.77 Gal=3.14 gallon equivalent, 154.8m/3.14g=49.3MPGe)
