In a word, brilliant! But that doesn't mean perfect! I bought my 2007 Prius when it was 2 yrs and 9 mths old, it now has 138,000 miles on the clock. In that time it has had 2 repairs, a broken suspension spring and a replacement tail light bulb. The average mpg over that 5 years is 58.3, and that is 100% accurate, I always fill up and note the miles. The on-board mpg indicator can be very inaccurate, but overall on average is about 2 mpg optimistic. The mpg figure has improved each year, the last year being average 62.8. Whether that’s because the engine gets looser with mileage or because my driving technique is improving I don’t know. A significant chunk of my driving is on motorways as I use the car for work. I knew very little about Priuses when I bought it, I just wanted an automatic that gave a good mpg. I just don’t understand why everyone doesn’t have one! I note that in most cities, including my city (Leeds), Pruis taxis are very commonplace. Here’s to the next 5 years!
