Prius fuel economy is nearly as efficient a decade and 206K later
Prius batteries hold up pretty well afterall

One of the big questions that consumers have when shopping for a hybrid on the new or used car market is “How long will the batteries last”. That question is the one that at times keeps people previously interested in a hybrid from buying due to the thought of an expensive battery replacement years down the road.

Consumer Reports Car Blog has answered the question of how well a used Prius performs recently. The blog got its hands on a 2002 Prius that has 206,000 miles on the clock, put the car on the test instruments, and pitted it against a 2001 Prius that they tested back when the car was new with 2,000 miles on the clock.

The results are very impressive. The 206,000-mile Prius performed nearly identically to the 2001 Prius. When the editors tested the 2001 Prius with 2,000 miles on the odometer, it racked up highway mpg of 48.6 and city mpg of 30.5. The 206,000-mile 2002 Prius on the same instruments coughed up 46.3 mpg on the highway and 32.1 mpg in the city. This brought the overall combined fuel economy number to 40.4 mpg compared to the new 2001 Prius combined rating of 40.6 mpg.

The 2002 Prius with 206,000 miles on the clock is also reportedly still on the original battery, engine, and transmission. The performance tests show that the car is just almost exactly dead on with the performance when new despite all the miles driven.

The editors at Consumer Reports note that replacement costs for the Prius battery could be as much as $2,600. However, they point out that a Prius owner could likely get a unit from a junkyard for about $500.

Toyota unveiled the latest hybrid called the Prius V back in January.

Which car does not need maintenance ?

why just mocking Prius?

which car has 200K on the odo does not require basic stuff like water pumps, alternator, timing belt, etc etc at least ONCE ?

if the car has 200K miles and it still get the same amount of mpg as an almost brand new one I would say that is pretty impressive.

The point is that you could take ANY car and pick a single unit to test and get the same results. This is not specific to the 2002 Prius.

I'm sure you could find a 1965 Corvette that runs better today than it did when it was new too, that doesn't mean that the majority of 1965 Corvettes run better than they originally did.

Now if they said that 50% or Priuses run within 90% of their original specs that would really be saying something. Saying that ONE Prius, even a randomly chosen one, (which this one wasn't) wouldn't be saying much.

Simply picking a running Prius with an original battery pack may easily put this in the top 10% of Priuses. Or it may simply be average. The problem is we simply don't know because the study didn't attempt to find out.

I"m willing to bet that more than 50% of Priuses run within 90% of their original specifications as those NiMH battery packs are extremely durable especially with the load profile they put on those packs even in city driving conditions.

And you put a lot of research into it huh?

309k prius -

32 prius taxis in canada some with over 300k miles -

prius taxis in Denver with over 200k -

You can't even be bothered to do a simple google search yet you question the methods of the reporter? good job failing.

His point is valid. A single instance is meaningless.

It is impossible to draw any conclusions from any of your links. One of them was the self report of an enthusiast. The other two were taxi fleets. All they might signify is that Priuses work well as taxis. What is needed is analyses of cars driven under more typical driving conditions.
What I’d like to see is leased Priuses tested at the end of their leases. That data would be interesting.
