2004 Toyota Prius: Higher Age, Lower Fuel Economy
September 14, 2010
Yep, we still have a 2004 Toyota Prius in our long-term fleet. It may not have as many miles as some out there, but we recently broke the 80,000-mile mark. We used this as an excuse to compare the first 10k of Prius fuel efficiency to the last 10k.
Our lifetime average in the Prius is still 40.4 mpg. But after roughly 5 years of ownership our average fuel economy is down about 5 mpg (for reference, our 65k-Flex shows no mpg degredation between similar intervals). Imagine this is your Prius. Would this trend concern you?
