In the previous Open Thread post for our 2004 Toyota Prius, commenter liquoredonlife asked what was the worst MPG it has ever gotten. We've just posted last month's fuel economy of our long-term test cars so you saw that the worst for the Prius was, gasp!, 18.5. But I was curious about how many times during its six years with us we've gotten its mpg below 20.
Turns out that 18.5 was a miscalculation that arose from a previous "short-fill" situation. Once we threw that one out, the correct value for lowest mpg ever is 26.7.
Head for the jump to see a breakdown of our Prius' fuel economy history ever since it first arrived in our fleet.
The last time we had that high 59.3 mpg was back in October 2004. And we haven't really gotten that close to that number since. Second best mpg was 54.8 that same month.
