The first decade of the Toyota Prius – Click above for high-res image gallery

As of 2010, the Toyota Prius has been available in North America for a decade, and it remains by far the best selling hybrid both here and around the world. Since its Japanese market introduction 1997, drivers have bought more than 1.8 million of the gas-electric dynamos, with about half of those ending up in the United States (and apparently half of those landing on driveways in the San Francisco Bay area!).

The original Prius was a gawky-looking four-door sedan that was slow and often didn't meet up with customer's fuel economy expectations. It wasn't until the second-generation model arrived in 2004 with a new teardop hatchback body style that the Prius really took off. By 2007, cumulative sales topped half a million, with the third generation model arriving two years later offering improved efficiency and better dynamic performance than ever. This year, Toyota has begun to deploy a test fleet of plug-in Priuses with lithium ion batteries with full series production of those versions coming in 2012.

While we wait for our future corded Prius models to give us even more pull with our eco-minded friends, we'll join Toyota in celebrating the now-iconic green machine by checking out the historic gallery below.

Toyota Celebrates 10 Years of Prius

TORRANCE, Calif., July 27 /PRNewswire/ -- Ten years ago Toyota launched a new kind of car in North America. It was the Prius, an affordable car with a hybrid gas/electric powertrain. In the decade that followed, the Prius made an indelible mark on the automotive industry. The car with the signature wedge shape proved to be an agent of change, and a catalyst for innovative ideas. Over 1.8 million units have been sold in the world to date, with nearly 900,000 in the U.S. alone.

"Toyota recognized in the 1990s that sustainable transportation would become a huge challenge in the coming decades," said Jim Lentz, president and COO of Toyota Motor Sales, USA, Inc. "Those realizations proved accurate, and if anything, even more profound considering what we know today."

It's hard to say what would have happened, had there been no Prius in the U.S., but in the 10 years since the car has been available, significant benefits have accrued. Nearly 900,000 people who chose to drive a Toyota Prius versus the average car have prevented an estimated nine million tons of CO2 from entering the atmosphere,* conserved approximately 650 million gallons of gas,** and saved an estimated 1.5 billion of their hard-earned dollars.***

The first Prius came to North America in July of 2000. That year, the hit of the North American International Auto Show in Detroit was the Hummer H2, and national gasoline prices averaged about $1.50 per gallon. Modest Prius sales goals of 12,000 units a year were set.

Not all early reviews were flattering. One car magazine said, "With a real-world 35 mpg, this is a car that neither enthusiasts nor greenies can fully embrace." Competing manufacturers announced that hybrids were "not an economical or practical solution" to America's future needs. Many insisted that Toyota had provided the solution to a problem that did not exist.

Prius owners, however, felt otherwise. Widely characterized as extreme environmentalists, early Prius adopters were actually more likely to be tech-savvy professionals. Those first owners, well aware of public events and global developments, were conscious of the impact of their own choices. They became articulate advocates for the technology. Soon, demand outstripped supply, and production had to be stepped up as waiting lists became months long.

In fact, Prius sales were driven by a number of factors. As fuel costs spiked, a clear economic rationale for purchase emerged. But more significantly, the Prius realigned customer expectations as to what a car should be.

Driving a Prius delivered a new kind of satisfaction, based on a new set of values. It was a car enriched with advanced features, in tune with global issues that assumed greater importance every year. It provided an affordable transportation solution that earlier all-electric cars did not, as it was able to use existing infrastructure without concerns for recharging or range limitations.

Today, the Prius has become a mainstream vehicle. It is the third-best selling car in the Toyota line, and an icon for the company. Owner loyalty figures are among the highest in the automotive industry.

Refining The System

Each generation of the Prius has moved the bar higher. When the first-generation compact Prius was launched in 2000, buyers got 97 combined horsepower and were told to expect 41 mpg. Ten years later, the midsize Prius has 134 horsepower and delivers an EPA rating of 50 mpg overall.

Improvements have been continuous. Compared to the original car in 2000, the 2010 Prius is bigger, faster and even cleaner. While the first generation was classified as a Super Ultra Low Emissions Vehicle (SULEV), the current Prius is a SULEV/AT-PZEV, meaning that it meets super-ultra-low-emissions-vehicle requirements, and emits zero emissions at rest. Further innovations, like the solar powered ventilation system on the 2010 model, contribute to the car's reputation as a harbinger of future trends and technologies.

As time went on, the media gained a better understanding of Prius. The editors of Motor Trend magazine, in naming the Prius "2004 Car of the Year," were "thoroughly impressed with the Prius as not only a technological marvel, but as a truly liveable sedan." The Car Connection described it as "Nothing less than the world's most sophisticated powertrain ever delivered to ordinary customers." Highly visible celebrities became owners, helping make Prius an aspirational eco-car.

In The Beginning...

The development of the original Prius, like sending a man to the moon, was a daring project with many breakthroughs and discouraging setbacks. What started as a conceptual exercise between a few planners and engineers ultimately became an intently focused, determined corporate priority. Creating the vehicle that became the Prius was accomplished in a relatively short amount of time through use of computer models to design and prove ideas. By minimizing the use of prototypes, Toyota engineers changed the way cars are designed and built.

Many of the components had to be invented from scratch. Those that had already been invented, such as regenerative brakes and electronic power steering, needed to be improved and adapted for mass production. Global standards for electronic components had to be set, and new software written.

A total of nine on-board processors were needed to manage the power delivery between engine, battery, brakes and motor/generator. Many motors and batteries were developed, tested, and discarded before they could be proven. Engines had to be converted to run on the more efficient Atkinson Cycle to power a new, unique transaxle.

A completely new type of instrumentation had to be developed. With the Prius, there was a need to monitor the interplay between the engine and the battery, leading to a display that kept the driver informed of his status on both counts. The new instrumentation empowered the drivers to improve mileage by altering their technique, turning driving into an interactive game. Today, mileage feedback displays are in use on almost every new vehicle on the market.

Unprecedented quality-control standards had to be instituted as motors and batteries that had been reliable enough for stationary use proved vulnerable to heat, cold and vibration. Multi-million-dollar joint ventures were established in order to assure the G21 Project, as it was called, could one day lead to a mass-produced vehicle.

These investments were made in an automotive environment that was dominated by sales of trucks and SUVs; in a world that The Economist magazine described as "drowning in oil." Through it all, Toyota management remained convinced that their goal of combining fuel efficiency with environmental performance would one day be appreciated.

Today there are nearly 30 hybrid models on the road from 12 brands, with more on the drawing boards. Many of the patents filed during the development of the original Prius are now licensed to manufacturers who also take advantage of Toyota's initial R&D investment. Nevertheless, one out of every two hybrids on American roads is a Prius, which remains the benchmark to which all hybrid cars are compared.

The Prius of the Future

There may be many futures for the Prius and Hybrid Synergy Drive, but one significant advancement, the Prius Plug-In Hybrid (PHV) is already here. A fleet of Prius Plug-In cars is now in a global-demonstration program aimed at proving the capabilities of the cars and fine-tuning the design to meet customer expectations. The car is designed with small Lithium-Ion battery packs that will help the PHV produce even less greenhouse gas emissions than conventional hybrid vehicles. A commercial PHV is scheduled to go on sale in 2012.

Longer term, Hybrid Synergy Drive components and software provide a direct bridge to clean, efficient drivetrains of the future. And while breakthrough technologies are on the horizon, continuing gains in battery technology and internal combustion engines keep the Prius competitive. Even in a world of alternative fuels, electric cars and hydrogen fuel cells, it's a good bet that Prius cars based on Hybrid Synergy Drive will be around for a long time to come.

      and im supposed to care about toyota why exactly?!? fuel economy means absolutely squat to me! my number one concern is comfort! yes i have been in a prius, a 2005 actually and it was way to narrow, the seats are stiff as plywood, and my 85 grand marquis has more balls! that is sad because it too doesnt have an abundance of power! there are better cars than toyota! atleast when other auto makers have a recall, it is recalled right away! unlike toyota, who has covered up their issues for years! do you really want to subject your family members to a toyota, knowing the fact they cover up their mistakes! do you really want to take a chance and buy a toyota and end up dead because that imported pos couldnt be stopped! i dont care that my car is 25-years old! it run beautifully, is ungodly comfy, and has freezing cold a/c! why would i give that up for some faulty pos, whose manufacturer couldnt care less about safety!
        • 5 Years Ago
        You are one retro smug.
        • 5 Years Ago
        no, im just a 28 year old who loves real cars from companies that dont hide crap for years and expect everyone to be ok with it! by the way, more recalls from you know who!
      • 5 Years Ago
      Interesting that a decade is also how long it's been since the Toyota brand has had a decent performance car (MKIV Supra died in 1999).
        • 5 Years Ago
        Who wouldn't trade that decade of Piouses for another decade of Supras?
        • 5 Years Ago
        I dunno about you, but I'd get a HUMMER over a Pious any day of the week.
      • 5 Years Ago
      A decade later, and it still looks like a cheap tin box.

      How bout a little STYLE Toyota????

      • 5 Years Ago
      Headline should read: Toyota celebrates a decade of deciet and decaying quality. Whereas, the Toyota dealers can celebrate a decade worth of in their service department just for all the recalls in one model year.
      • 5 Years Ago
      Yay! One decade of clogging up the left lane.
        • 5 Years Ago
        My wife had a gen-two Prius, and I found that the CVT made it surprisingly easy to creep up well past the posted limit on the freeway. I'm used to manuals, and my ears being the speedometer (corresponding with engine rpm in top). But with the CVT, well... once, "my friend" was on I-5, looked down at the speedo, and lo and behold, 110. Must've been a downhill, with a tailwind...
        • 5 Years Ago
        I know, right?

        WTF is up with Prius owners who are flying around at 90 mph? Have they ever seen how skinny their tires are?
        • 5 Years Ago
        I park in the right lane, obey all speed (aka REVENUE) laws, use my signal, do not fluctuate speed, do not talk on phone nor text like so many dangerous kiddies. I am the ideal driver.

        Plus, I am NOT disappointed by fuel economy per the original AB text, and get 51 mpg overall. My 2001 ten year old 113k miles Prius looks great but is not babied.
        • 5 Years Ago
        If only they were flying along at 90.

        Usually, they're dawdling in the left line, blocking traffic like a bunch of tools.
        • 5 Years Ago
        True... but for some reason, here in the DC area, I see lots of Priuseses, Yariseses, and Echoes (huh... all of them Toyota appliances) whipping along at illegal speeds.

        The drivers either don't realize that they are not driving vehicles actually equipped to maneuver at such speeds, or they figure they get a free pass since they allegedly get good fuel mileage.

        I drive an R32, which gets rather craptastic mileage. However, I have a really, really short commute to the office. So, I fill my tank *maybe* twice a month. The skinny-tire snob brigade in their hybrids think they are such good citizens, even though they are burning WAY more gas than me.

        But yeah, these dolts tend to block the few of us who actually enjoy driving with their pill-shaped mistakes.
      • 5 Years Ago
      I'll celebrate when I never see one again.
      • 5 Years Ago
      where did all the gen 1 and 2 Priuses go?...there are noneto be seen and I am in calif.
      I think they are bought back and scrapped to keep the prices up and to avoind repair stories.
      • 5 Years Ago
      I agree. People keep judging the Prius on the basis of their "auto enthusiast" snobbery badge. Wake up, you can't judge all cars this way. If this was a Mazda, everyone would adore it, but no one would buy it. Since its not, its the other way around.
      Taken as a whole, yes it is slower, but you get a great hatch setup, quiet/smooth highway manners and good packaging in a design that is much tidier then the Camry (or most other family sedans). Get over yourselves enthusiasts, this car has as much right to be in our driveways and on our roads as any other well designed, affordable vehicle.

      /not a Toyota fan, just tired of auto snobs

      So toyota you decided if you cant beat them(HYUNDAI) JOIN THEM IN 2012 WITH A lithium batterie.....

      • 5 Years Ago
      What a bunch of bandwagoneers. Look, I don't like the Prius. I don't like Toyotas at all (I have said as much many times). However, there is no question that the Prius is a SIGNIFICANT vehicle.
      • 5 Years Ago
      I DESPISE these atrocities, but emotions and opinions aside they sit firmly at the top of everyones hybrid of choice...10 years...it really doesnt seem that long...but they really are a success story even though they drive like crap and handle like Red Ryder....and people STILL buy them in droves.....no denying that is there...CRAZY!
        • 5 Years Ago
        I'm pretty sure taking the language you speak seriously is not a bad thing. What's with the ellipses abuse anyway?
        • 5 Years Ago
        Hey zing: "Your"?

        • 5 Years Ago
        Wow, airchompers reeks of prius smug. Your the reason why I don't like the prius.
        • 5 Years Ago
        just a tad judgemental arent we? And yes I can afford one, but there are better alternatives...but thankyou for yours and the Grammar polices input, much appreciated....
        • 5 Years Ago
        nice to see BLOGS being taken so seriously...get over yourselves guys, its NOT prose, so quit displaying Doctorates in A-hole....sorry you werent picked for the sports teams...glad to see you took English so seriously so as to frequent BLOGS to ridicule people.
      • 5 Years Ago
      WHO CARES!
        • 5 Years Ago
        I'm totally with you on that one emperor. I LOVE hybrids, plug-ins, not that I would ever get one. But the less cheap fossil fuels other people use, the more there is for the rest of us, who actually enjoys burning sweet dinosaur into for four-legged animal power!

        Everyone else should get a plug-in. You are not worthy!
        • 5 Years Ago
        Well I think it's great. The less oil everyone uses in the aggregate, the better.
