Here are the final numbers: <p><img src="https://media.unpythonic.net/emergent-files/01420206916/mpg.jpg"> <p>For everyone not still suffering under the tyrrany of imperial measures, 44.4mpg is around 5.3l/100km and the distance driven is about 12000km. <p>That means ... <ul > <li >260 hours total driving time</li> <li >43 minutes driving time per day</li> <li >21 average miles a day (33km)</li> <li >170 gallons of fuel (640l)</li> <li >2/3 gallon per hour of driving (2.4l/hour)</li></ul> <p>Getting at 44.4mpg instead of the EPA combined fuel economy of 50mpg means using 20 extra gallons of fuel over the course of the year, 13% more than predicted. <p>Overall we're happy with the Prius. It's much roomier than the car it replaced and it has better fuel economy. However, I'm a bit sad we didn't get closer to the EPA fuel economy. <p>The main thing lowering the fuel economy is short winter drives. My drive to and from work is just 2.5 miles per direction, and I often drive a similar distance to and from lunch. In winter, that's too little distance for the car to warm up to the point that it enters the fuel-saving EV mode while stopped at lights. (this kind of driving is even classified as &quot;severe operating conditions&quot; by Toyota: &quot;Repeated trips of less than 5 miles in temperatures below 32 degrees Fahrenheit&quot;) <p>Our summertime fuel economy (also the time of year when we make long driving trips on the highway) is closer to 48mpg.
