Toyota Prius. We all know the story. This was the hybrid that changed the way we look at hybrids. While the original Honda Insight holds the honor of being the first U.S.-sold hybrid, the Toyota Prius was the first offered to consumers (in Japan). But the second-generation Prius holds another distinction. It's the hybrid that made the largest impact on the automotive community and it became the poster child for the "Hey, look at me; I'm green" crowd.
Which, as it turned out, is a sizable crowd. When the updated 2004 Toyota Prius hit the market, it brought the masses. Look in your neighbor's driveway. There's a Prius. Now glance at the car in the lane beside you. There's another Prius. They're everywhere. Heck, Tom Hanks has one. So does Cameron Diaz.
Well, we weren't about to stand idle as the world passed us by. Before our local Toyota dealership even stocked the new version of its hybrid sensation we were shopping for one. It wasn't long before we purchased a Seaside Blue Pearl second-gen Prius for our long-term test fleet.
Why We Bought It
We have to turn back the clock several years to unlock our reasons for buying the Prius. For 2004 Toyota completely redesigned its first-generation hybrid. Season two added Hybrid Synergy Drive, a full hybrid system with a more powerful 1.5-liter gas engine producing 76 horsepower and 82 pound-feet of torque. Gasoline power was backed by an electric motor generating 67 hp and 295 lb-ft of its own. Efficiency improvements earned the new Prius a bevy of marketing acronyms. It was a SULEV (super ultralow-emissions vehicle). It was a PZEV (partial zero-emissions vehicle). And it was environmentally BA (badass).
Toyota groomed the Prius to be king. When the 2004 model arrived, its popularity soared well above other existing hybrids like the Insight and Civic Hybrid. We'd like to say we predicted the Prius would become the Slug-Bug of the new millennium, and that's why we bought it. But our test began merely as an assessment of its emerging new technology. Nearly 400 new patents were issued for the 2004 Toyota Prius. This was a significant vehicle. Its hatchback versatility and top-ranking fuel economy made it a consumer must-have and secured the Prius an extended stay in our long-term test program.
Our early Prius questions remained. Are the HOV-access stickers worth the money? Would fuel economy decline as the batteries aged? How long until the batteries failed and how much would it cost to replace them? But as our Prius test grew in length, it also evolved. Why we bought it became more of a question as to why we kept it. And six years later we were finally ready to part with our benchmark, second-gen Prius.
Drive and Durability
There was a general consensus when it came to how the Prius drove. Senior Editor Erin Riches echoed our sentiment, "Ride quality is not a strength of the Prius. The suspension keeps the ride reasonably smooth on the highway, but it's about as forgiving as my mom's '93 Accord — tolerable by today's standards but not ideal. There's also quite a bit of road noise. Besides that, the driver seat gets uncomfortable on long hauls. The biggest problem is the minimal number of adjustments. The steering wheel is mounted close to the dash and it doesn't telescope. On a positive note, the second-gen Prius is acceptably quick for a hybrid. During one trip I drafted off the trucks on Highway 46 while waiting for an opportunity to pass. Full throttle was essential for passing but it was hardly a white-knuckle event."
Inside the cabin our Prius boasted an early-generation touchscreen media interface and a cassette player. It was bare-bones by today's standards. Even its cloth Ivory interior left something to be desired. Senior Photographer Scott Jacobs reflected on the last night he spent in the Prius. "My roommate in college had a denim couch that he absolutely loved, but the rest of us hated. It had a sickening dark sheen from pizza grease, cigarette ash and spilt beer. We nicknamed it 'Deal Breaker' because its vile presence would horrify any woman who came to our apartment. The Prius has become the new 'Deal Breaker.' The combination of dirt and sunscreen has made the driver side armrest akin to that damned couch. When I drove the Prius last night, I made sure my skin and clothing did not touch the armrest."
Our Prius was not without its problems. We averaged about $135 per visit for routine maintenance as recommended by the owner's manual. This average included a couple of $22 do-it-yourself oil changes. Other repairs were minimal. We replaced the brake pads ourselves at 86,000 miles for $64. New tires at 84,000 miles remedied a stability control warning issue. Mounted and balanced, these new Bridgestone Ecopias set us back $460 and performed equally as well as the OE Goodyear Integrity tires. Extreme curb rash enticed us to buy a new front wheel cover, which cost $380 and concluded routine out-of-pocket expenses.
Aside from the routine we had some notable non-warranty items during our test. One came in the form of an electrical short in the navigation unit. Another resulted from simultaneous failures of the air-conditioning compressor and inverter pump at the 71,000-mile mark. This was expensive and took days to fix, but Toyota recently began accepting refund applications for the inverter pump issue as part of a "customer satisfaction campaign." At the time of this wrap-up we've submitted our application and hope for a full repayment.

Performance and Fuel Economy
One thing was clear after 84,000 miles of testing the Prius. Performance is not an area where this vehicle was meant to excel. But we knew that going into the test.
The next morning I woke up and decided to buy the car myself.
Give the Prius a quarter-mile of asphalt and the hybrid will dispatch with it in 17.7 seconds at 78.0 mph. It needs 10.2 of those seconds (with 1 foot of rollout) to reach the 60-mph mark. And from 60 mph the Prius returns to a stop in 124 feet. Each of these tests ranks the Prius as average among the hybrid populace. Its slalom speed of 59.8 mph and 0.72g of lateral force around the skid pad are similarly bland.
Where performance ends, fuel economy begins. We averaged 40.9 mpg during our test. Admittedly, much of that mileage was accumulated with little concern as to our overall fuel efficiency. That didn't mean the Prius couldn't perform when asked. We found that even toward the end of our test the Toyota could attain 50-plus mpg with little effort.
Best Fuel Economy: 63.5 mpg
Worst Fuel Economy: 26.7 mpg
Average Fuel Economy: 40.9 mpg
Retained Value
When we purchased our Prius, there wasn't a dealership in town that would sell one without a markup. So we went to another town. We didn't need to go far before locating a dealership willing to sell at MSRP. We paid $26,053 to the Internet sales director at Carson Toyota for a Seaside Blue Pearl Prius with Ivory interior.
Six years later it was time to sell. After 84,000 miles Edmunds' TMV® Calculator valued the hybrid at $8,476 based on a private-party sale. This equaled 67 percent depreciation, a valuation directly reflective of its length of service. Senior Consumer Advice Editor Phil Reed then took the keys, as he usually does when we sell long-term testers. This time was different, however.
Reed discussed the process. "I was preparing to put the Prius up for sale, so I drove it home one Thursday afternoon. I left the office a little late and when I hit the 405 freeway it was locked up solid with traffic. I swung into the carpool lanes and cruised along at 50 mph past miles of stopped traffic. The next morning I woke up and decided to buy it myself. I've really been enjoying driving it — it's the perfect commuter car."
True Market Value at service end: $8,476
What it sold for: $8,476
Depreciation: $17,577 or 67% of original paid price
Final Odometer Reading: 84,033
Summing Up
Our test of the Prius began just like any other long-term test. We bought the car to drive around for a year and reflect on its emerging technology. As time passed, the focus of our test changed.
Toyota built this hybrid to stand out among its peers. It set the benchmark for 2004 and beyond. During our extended test we watched the popularity of the Prius soar. Buy it for status. Buy it to save the environment. Buy it for the HOV stickers. It didn't matter why, but people were buying the Prius and doing so in droves. All the while automakers did their best to copy the mold cast by the second-gen Prius.
Today much of the same excitement surrounds the Toyota. This is easily among the most significant vehicles of the past decade. It arguably sits atop that list. When judging its popularity we need look no further than our own ranks. We drove a 2004 Toyota Prius for six years and racked up some 84,000 miles. Then we sold the car, to ourselves. We can't give the Prius much more of an endorsement than our own, hard-earned cash.
Edmunds purchased this vehicle for the purposes of evaluation.

I too have a 2004 and I love it! No major repairs except routine maintenance. Best car I've ever owned. I have to laugh at the imbecile that loves CNG. I feel sorry when he/she runs out and ends up having the car towed. LOL!! What a POS!!

I have a 2004 Prius just like this one. I have the Nav, etc... LOVE THIS CAR. I now have 138,000 miles on it. I have driven it in the mountains of SW Virginia, the plains of beach areas, and the rolling hills of the Piedmont. I have passed other vehicles on the interstate with ease, and laughed as they pulled off for gasoline. 80 MPH is easy. Curvy roads are easy. Mountains are easy. The only place I haven't been able to drive her is up a very steep dirt road - and that was because the car has an automatic function that stops the front wheels if they start to spin.
I will drive this car until she dies completely. And about maintenance - I haven't done any other than oil and tire changes, windshield wipers. NOthing else. No need for brakes, no need for anything. Oh - I think my husband did change the air filters once.
The interactive screen was replaced under warranty at one point, and a couple of other service bulletins I can't recall.... but she's been out of commission only 3 days in the last 7 years. The interior is dirty, as I'm not a dainty female driver. I love my tools and use them hard, including my cars. But she is awesome, and I look forward to another several years before treating myself to a new one. (Or maybe I'll look at a HyCam, but that's to be decided.)
This car has transported babies, toddlers, and now a 6 year old. There are probably still cheerios under the seats. It has been packed floor to ceiling with various pythons, boas, lizards, and frogs (I operate a reptile rescue). It has transported furniture and tools - it is quite large with the seats down. It has helped power a house when the electricity was out. And, the one thing it did that nothing else has ever done - it made me look "cool".
I love Sipper. 'nuf said.

Bought a Prius few months ago as I am expecting the oil price to reach $5 in the next 2 years.
Originally wanted a Golf TDI, went to test drive, loved how VW drive and feel, disliked the colors and too little options, not totally excited about the new look. The deal breaker was the crappy dealers knew nothing about their cars but tried to sale me over MSRP (25k for a 4dr DSG, I am a family man...). The Toyota dealer on the other hand, offered me 3k below MSRP (around 20k) and I bought one. The Prius is smooth and I averged 47 mpg on rush hour freeway, no complain so far. Although I won't want to drive it fast on twisty roads.
Can't beat that $5k I saved over TDI, which is good for a fairly new Ducati or Triumph if I need some fun.

Phil,
Glad that you had the option of buying strictly a commuter car, but some of us don't. I have the family mobile and my commuter car. I could choose boring, or I could have a little fun on the way to work (and on the weekends).
So I have a Mazdaspeed3 GT. Can still load the family (and a bunch of other stuff). Commuting I get 25-27 MPG. Got it for 22,5 out the door (much less than a Prius with most of the same stuff, maybe more options on the 3, but it doesn't have a handy dandy graphic display of brake to battery power transfer, so we will call it even). :-)
So for the reality of the up-front cost difference, it mostly makes up for the gas cost. But what price can you put on the smile on my face.
Now granted, occasionally in rush hour I feel my sore clutch knee and look over at all the boring clutchless cars around me and think, hmmm, maybe....NAH.

Please keep us updated Phil. I'm an auto enthusiast so I have a hard time warming up to the Prius but I can also appreciate good, interesting engineering solutions and would love to see how your Prius holds up as you continue to put miles on the car.
I'm not sure I could own one but I do know there are several days every week where I'm sitting in gridlock in my enthusiast car watching Prius drivers scream by me in the carpool lane and I'd be lying if I didn't say I was envious.

Brace yourself because I'm about to make a really controversial statement.
I think the VW TDI is a sensational car, particularly the current redesigned TDI. Now here's the really amazing part. I ALSO think the Prius is a great car. If I was driving on any roads that were twisty, I'd much prefer the VW. If I'm commuting between my house and the office, and I can get into the carpool lanes with the Prius, I'll take the Prius. My purchase of the Prius was a practical decision, not a desire to thumb my nose at anyone, and certainly not a statement of my political position. And it was especially not a move to try to prove VW TDI drivers wrong -- because they're not.
If someone says the Prius is a blob to drive, I completely agree. But to me, that's like saying a hammer is bad because it doesn't cut wood. IF you want to cut wood, use a saw.
I'm glad there are some who are still interested in the Prius and I will check in and let you know how things are going. I'm still enjoying driving it. And right now, I'm working to get the $700 back for the inverter we paid to have replaced. Toyota has said they will refund the money now that they have launched a goodwill campaign to fix it.

Average 40.9 MPG?? That happens to be 1 MPG more than what I average in my 2010 VW Golf TDI. And the TDI is torquey and super fun to drive, without long-term battery hassles.
Of course my car has 6 years on this one, but hybrids ain't quite all that...

Agree with Superjet. CNG is the simple domestic solution. NG is available in every city with a virtually infinite supply. Any vehicle on the road today could be quickly & inexpensively produced to burn CNG. No complicated NiMH battery & onboard computerized charging system.
I have a '99 Civic GX which I bought from a gov't auction outside of Wash DC for ~$4000 about 18-months ago. I drive it on a daily basis to/from work about 60-miles roundtrip and average 30~36mpgge. CNG was about $1.50~ish per gge last year but is now about $1 since they removed the roadway tax once again.
My only repairs thus far have been the replacement of a failed CNG injector for $150 and a $12 oil pan gasket. I'd guess that I put close to 15k miles on the clock before changing the oil and it looked exceptionally clean.
During the last 12-months, I've driven 12177 miles for a total fuel cost $556.23 or roughly 4.6 cents per mile. With the cost per gge down to a buck, I'm at 3 cents per mile (or less). With gasoline in the vicinity of $3.15, most any gasoline car is going to be in the range of 9 to 12 cents per mile or more. Rough calculations lead me to think that a Prius would cost roughly 6 cents per mile.
CNG is the answer.

Are all the hateful comments that invariably pop up, no matter what the subject, because of the rough economic times, or is there something more rotten in the State of Denmark? It appears that the annonymity of the internet empowers all the little twerps of the world to spew their bile with precious little prompting. It's such a low way to live, and cowardly too.

wow, what a POS.
Lets start out with the fact the HOV stickers for Puis expire on June 1, 2011. You have six months to enjoy the HOV lane and then you will be getting out of my way.
second you get poor gas mileage (not to mention my car is cheaper to run)
you spend a lot of money on repairs
and you will spend more in a few years when the battery needs to be replaced.
Lets compare this POS to my commuter car.
I drive a 2007 Honda GX Natural Gas vehicle (CNG), I have 74,500 miles.
I have a clean Air Sticker good till 2016 (in white, not yellow like the Puis). because I run on alternate fuel, Natural Gas an all Domestic fuel source to boot....CNG is all American, try and beat that
Maint costs so far, new set of tires ($600 Costco), four oil changes (since CNG is clean, you only change the oil every 17k-20k (try that stunt in your Puis.....). cost $100.00. That is it for total maint cost $700.00
Plus I don't have a battery pack to replace in 10-years..
Now for MPG, Natural Gas sells for $1.99 a gallon and I get 40 MPG. So for $3.25 I can go 65 miles, try that in your Puis....
Lastly the Honda GX natural Gas vehicle is the cleanest running internal combustion vehicle in the US period.
I will laugh come June as I pass your new buyer of this POS on the HOV lane on the 405.
Good Purchase ISL.....ha, ha, ha...
