Full Test: 2001 Toyota Prius

Karl Marx, Your Hybrid has Arrived

    2 Ratings
    Last night I did some exhaustive research. According to my findings (obtained by renting "Sleeper" and "Blade Runner" from Blockbuster), the cars of the future will either be flying cars or these white, sanitized globular-looking people pods with as much appeal as a bowl of tapioca. Funny, after driving the 2001 Toyota Prius, I thought it was the car of the future.

    Automakers have been looking for ways to meet increasingly stringent demands for cleaner tailpipe emissions. In the '90s, electric cars like GM's EV1 were thought to be the answer, but they are limited by poor range and the fact that they have to be "plugged in" in order to be recharged. Hydrogen-fueled fuel cell cars will some day be the ultimate evolution of the automobile, as their exhaust byproduct is essentially water vapor. But the technology for fuel cell cars is still young, and mass-produced fuel cell cars are years away.

    For today and the near future, the best hope is hybrid vehicles. The Prius is a hybrid-electric vehicle, only the second such mass-produced car to be available in America (Honda's Insight was the first). Hybrid cars combine a gasoline engine with an electric motor. Since hybrids are still fueled by gasoline, they don't have to be plugged in or recharged. In the case of the Prius and Insight, the result of hybrid technology is reduced emissions and improved fuel efficiency when compared to a normal gasoline-powered car. The only fear has been that a hybrid vehicle would never be useful as a real car that real people would want to buy. With the Prius, Toyota has largely quieted those fears. Hybrids, we think, are here to stay.

    While the Prius is new to the American consumer for 2001, Toyota has been selling them in Japan since December 1997. Since that time, the company has been tinkering with the car and making changes that would better suit the higher sustained speeds, longer driving distances, more stringent emission requirements, and harsher climates found in the United States. Compared to earlier Prius models, U.S. versions feature more horsepower, additional emissions equipment and a more powerful battery pack that is also smaller and lighter.

    It might have more power, but the U.S. Prius is still a few fries short of an automotive Happy Meal. Its aluminum, 1.5-liter four-cylinder engine makes 70 horsepower at 4,500 rpm and 82 foot-pounds of torque at 4,200 rpm. The electric drive motor is worth another 44 peak horsepower, bringing the maximum potential horsepower output to 114. At the test track, our car accelerated from zero to 60 mph in 12.8 seconds and cleared the quarter-mile in 19.3 seconds at 75.3 mph. Your average V6 family sedan with an automatic transmission (like a Toyota Camry) will do zero to 60 in about 8 seconds, and a four-cylinder economy sedan's time is around 10 seconds.

    OK, so it's slow. But if all you are interested in is drag racing, big smoky burnouts and collecting John Force T-shirts, you've come to the wrong road test. Go buy a Camaro if that's you. What makes the Prius unique is that it is able to provide tolerable acceleration while also offering exceptional fuel mileage, squeaky-clean emissions, seating for five passengers and a good list of standard features. The EPA rates the Prius at 52 mpg in the city and 45 mpg on the highway, theoretically allowing over 600 miles between fill-ups. We officially observed a combined average of 41 mpg out of our test car, with one of our editors reporting that he was able to get higher amounts (around 47 mpg) during his driving stints. To learn about the Prius' unique technologies and components, we encourage you to read our Hybrid Highlights section.

    The Prius is available only as a four-door sedan with one trim level. With this, you get plenty of standard equipment, such as automatic climate control, air conditioning, power windows and locks, power steering, antilock brakes, keyless entry, and dual front airbags. The only options of note are floor mats, a single CD player, and an in-dash six-disc CD changer. Though there is a button on the dash labeled "map," GPS navigation is currently not available in the American market. Cruise control is another MIA feature. You can't even get it as a dealer-installed accessory. We do know it exists, though, as Prius models sold in Canada can be had with cruise control. We're not sure what Toyota bean counter made this decision, but if there was ever a country whose wide-open geography and Lay-Z-Boy attitude demanded cruise control, America is it.

    Visually, the Prius (which is Latin for "to go before") looks a little like Toyota's Echo Sedan. They both have a pug-faced snout, a high roofline and short front and rear overhangs. Nobody on our staff thought it was particularly attractive, but it's certainly not ugly, either. In terms of overall size, the Prius is closest to the Corolla, though it's taller and shorter. It has a 169.6-inch overall length and a 100-inch wheelbase compared to the Corolla's 174.0-inch length and 97-inch wheelbase. Despite being shorter, the Prius has a slight edge in interior passenger volume compared to the Corolla, and it has more rear legroom, too. Accommodations are surprisingly good for a small car, with upright seating positions and good outward visibility. Two adults will fit in the backseat without too much complaint, and the trunk holds 11.8 cubic feet of cargo, a capacity that is similar to cars like the Honda Civic and Nissan Sentra.

    The rest of the car, however, isn't very similar to a Sentra, or any other car, for that matter. The bridge on the Starship Enterprise is a better match. Hop into the driver's seat, and you'll be greeted by a blank stare from the dash. Similar to the Echo's interior design, there is no gauge cluster in the typical sense. Instead, there is a centrally located digital display that informs drivers of speed, gear selection, fuel status and trip distance. Below it is a symmetrical, T-shaped instrument panel housing a touch-screen LCD monitor and climate and audio controls. Between the instrument panel and the steering wheel, a transmission gearshift lever sprouts out of the dash like a cancerous growth.

    The Prius' interior certainly seems like an attractive and futuristic package when you are just sitting and observing. Material quality is decent, and Toyota has given the Prius plenty of its own unique switchgear. There are problems, though. Public offender number one is the location of the gearshift lever. Yes, it frees up space from the center console and floor, but when the lever is placed in drive, it hinders access to the volume knob and radio scan button. This means that every time the driver wants to adjust the stereo's volume or change a radio station, she has to first skirt her hand around the lever. This takes concentration to do, and that means reduced driver safety. The same goes for the radio presets, which can be accessed only via the LCD display. Since they are touch-screen operated and have no tactile feel, the driver must take her eyes from the road and look at the screen in order to pick a preset. Other minor quibbles are mediocre interior storage, no driver armrest, and the long time required to get used to the central location of the digital gauge cluster.

    Twist the key and the engine thrums to life after a brief delay. The digital display informs the driver that the car is "ready," which we suppose is the Prius' version of a thumbs-up. The LCD monitor, meanwhile, has a virtual button for either "energy" or "consumption." Stab "energy" with your index finger, and the screen displays a pictogram showing power flow between the engine, wheels, electric motor and battery. The "consumption" bar chart, though initially confusing, is useful as it shows a scrolling fuel mileage status report that is updated in 5-minute increments. Neither display does much with the car just sitting, though, so it's time to drive somewhere.

    Move the shifter lever into the drive position, and the Prius shoves off. How it does this, however, is perhaps the most intriguing method of propulsion you'll find in a car today. At low speeds and light throttle applications, the Prius relies completely on the electric motor for acceleration. This means that when the car is accelerating gently from a stop, driving around a parking lot, creeping through a McDonald's drive-thru, or even cruising at 35 mph down a city street, it might be doing it with 100 percent electrical power. The engine, meanwhile, is completely inert.

    The obvious benefit to this is that if the engine isn't running, it isn't using any fuel. This attribute is a big contributor to the Prius' city EPA rating of 52 mpg. The other payoff, though, is that it is quiet. The electric motor makes virtually no noise, and the effect is a little disconcerting at first unless you've driven the EV1. Think of the Prius as an equal opportunity user. It is constantly monitoring speed, throttle position and battery power to determine what method of power will be the most efficient. It could be just the electric motor or a combination of both. It's a very fluid process and does not impede driving style at all. Bring up the energy chart on the LCD, and the Prius will happily tell you exactly what it is doing in terms of resource management. The engine is responsible for recharging the hybrid battery, and the Prius is also capable of recapturing some energy when it is coasting or braking. We found that heavy and constant use of the throttle will deplete the battery, however, so it's best to be a little conservative with your right foot.

    In all other respects, the Prius pretty much drives like a regular car. Since it has a continuously variable transmission, there are no actual gears to select. The choices are simply park, reverse, neutral, drive or brake. The brake function is there because CVT transmissions don't have the characteristic of engine braking that regular manual or automatic transmissions do. When placed in this mode, the Prius will gently apply the brakes to make it seem like the car is engine braking. This only happens when the driver lets off the throttle.

    Toyota's hybrid is perfectly suited for urban driving and commuting. The compact exterior dimensions and short turning radius make it easy to park, and the ride quality is fairly compliant. In fact, the more congested the driving environment is, the more the Prius makes sense. While stuck in a particularly nasty traffic jam during our evaluation period, we couldn't help but feel superior to all the other drivers on the freeway. With traffic at a near standstill, the Prius' relied solely on its electric motor to provide all the power necessary for the stop-and-go nature of the traffic jam. You almost feel like an environmental champion driving this car when you realize that its super-ultra-low-emission vehicle (SULEV) status means that it is 90 percent cleaner than LEV vehicles for smog-forming exhaust gases.

    On the highway, the Prius still does an acceptable job. Wind and engine roar are minimal, though the low rolling resistance tires make lots of noise and like to follow grooves in the pavement. Driving at higher speeds, the electric motor can't provide as much thrust, so care must be taken to plan out passing maneuvers. There is little point in trying to drive the Prius like a sports car, as its soft suspension and light steering make for unpleasant cornering. The CVT, while fine around town, gets easily befuddled when driving up hills, and constantly searches for an engine rpm that it is happy with. Another problem is the feel of the brakes, as they can be hard to modulate. To their credit, though, our test car stopped from 60 mph to zero in 135 feet, a number that is equal to or a little better than most economy sedans.

    What makes the Prius so impressive is that it drives, for the most part, just like a regular economy sedan. It is true that acceleration is pokey, especially when four adults and some gear in the trunk are along for the ride. There could also be long-term reliability issues (as there would be with any car with such new technologies), though Toyota preempts any worries with an eight-year/100,000-mile battery and hybrid warranty, as well as complimentary roadside assistance and three-year basic maintenance programs.

    Our take on this "car of the future" is that it gives up very little, especially considering the payoffs of over 40 mpg and SULEV emissions. Even the price is impressive, with a 2001 MSRP of $19,995. Toyota says that it will break even for every Prius that it sells, though that statement probably does not take into account the company's research and development money spent on the car. But who cares? The only other hybrid on the market is Honda's Insight. The Insight delivers better fuel mileage, but it is much more specialized. The Prius is a hybrid that is actually useable. It's a hybrid for the masses.

    Road Test Summary

  • The Prius is a hybrid-electric vehicle (HEV), only the second such mass-produced car to be available in America after Honda's new-for-2000 Insight. Hybrid cars still run on gasoline like regular cars (meaning they don't have to be plugged in or recharged), but they use an electric motor and battery to supplement the engine. In the case of the Prius and Insight, the result of hybrid technology is reduced emissions and improved fuel efficiency when compared to a normal gasoline-powered car. Due to their virtually zero-emission abilities, hydrogen-fueled fuel cell cars will some day be the ultimate evolution of the automobile. But that could be decades from now. Based on our experiences with the Prius, here is a tree-hugging hybrid that does an excellent impersonation of a regular car. Hybrids, we think, are here to stay.

    Acceleration Comments:
    Considering this vehicle's mission in life, I was not disappointed with the acceleration numbers. It actually felt better than the numbers indicate. The CVT allows the engine to stay within the best power range. It is strange not to hear shifting going on when doing full throttle acceleration runs.

    Braking Comments:

    Regenerative brakes seem to give the brake pedal a different feel, a little firmer. You can tell that you are doing more than braking when you step on it. Under brake testing the nose did take quite a dive, but the front remained stable and true. The braking distance was very good for a vehicle in this class.

    Skidpad Comments:

    The skidpad was not available for testing.

    Slalom Comments:

    With weight from the gas and electric motors in the front and the batteries in the back this vehicle handled the slalom with a solid feel. The biggest limiting factor seemed to be the tires which could be larger and/or wider for better response, but would surely take away from the fuel economy rating. Toyota seems to have come up with a nice compromise between rolling resistance and all out stability.

    Stereo Evaluation

    System Score: 4.0

    Components.
    This is a nice little system in an impressive little car. Although it won't win any awards, it's pleasant to listen to and gives lots of enjoyment.

    The design is kind of strange, though. For one thing, the gearshift knob blocks the whole left side of the radio, making it difficult to see what you're doing. Also, most of the functions are displayed on a touchscreen (which doubles as an info center for the goings-on of the hybrid system) rather than a traditional radio display. To change stations, for instance, you have to hit a button to display the presets, then touch the screen. The same goes for tone controls and most other functions in the system. It takes a while to get used to this, but I found it less annoying after spending some time in the vehicle. To be frank, I loved the car so much maybe I cut Toyota a little slack here.

    Speakers include a pair of 5-inch full range speakers on the back deck, along with some larger 6-inch speakers in the front doors. There are no separate tweeters in the system.

    Performance.
    As stated above, it won't take home any trophies, but it fills the small cabin with a fair amount of sound. Bass is surprisingly boisterous, with a nice little kick drum in the bottom end. Cymbals sound good; so do horns and vocals. The amp holds out pretty well until driven hard, but what do you expect? Forty-five miles per gallon and great tunes too? Such a deal!

    Best Feature:
    Just a great overall value.

    Worst Feature:
    Gearshift blocks whole left side of radio.

    Conclusion:
    A nice little system in a wonderful little car. — Scott Memmer

    Hybrid Highlights

    One of the more impressive aspects of the Prius is its hybrid powertrain. Toyota calls it the Toyota Hybrid System (THS). The THS is comprised of both a gasoline engine and an electric motor. Based on driver inputs and other conditions, the THS selects the best combination of engine power and electric power to accelerate the Prius. Check out the diagrams on the right to see how the THS operates in different conditions.

    The THS consists of four main components. These are the 1.5-liter gasoline engine, the battery pack, the hybrid transaxle and the inverter. Following are descriptions of each, as well as an overview of the Prius' special emissions-reducing hardware.

    Engine
    If you look at the power ratings, the Prius' 1NZ-FXE engine might not seem all that great. It makes 70 horsepower at 4,500 rpm and 82 foot-pounds of torque at 4,200 rpm, about 30 less of each than the similar 1.5-liter engine in the Toyota Echo. The 1NZ-FXE does have numerous changes to enhance fuel economy and reduce emissions, however. Here are some highlights:

    • Variable valve timing. Used to improve performance and fuel economy.
    • Atkinson cycle. The Atkinson cycle is a refinement of the normal intake, compression, combustion and exhaust four-stroke engine cycle. Similar to the Miller cycle found on Mazda's supercharged Millenia S Sedan, the Atkinson cycle enables the duration of the compression stroke and the expansion stroke to be set independently of each other. Because the Atkinson cycle does not generate high output, there is no practical application for this system unless it is combined with a supercharger; however, this system offers a high level of thermal efficiency. On Prius, the Atkinson cycle's low output is negated by the electric motor's additional power.
    • Lightweight engine construction. Since the engine has been limited to 4,500 rpm, many internal parts have been designed to be lighter and produce less friction. The cylinder bores are offset from the crankshaft to help reduce friction. In addition, the crankshaft has a smaller diameter, piston rings have lower tension and the valve spring load is less, when compared to a standard high-revving engine.
    Hybrid Transaxle
    The hybrid transaxle is unique to the Prius. It has a continuously variable transmission mechanism and a power-splitting device that adjusts and blends the amount of torque applied to the front wheels from the engine and the electric motor. Actually, there are two electric motors, and both are contained within the transaxle. Both of the electric motors are compact, lightweight and highly efficient.

    Motor generator one (MG1) recharges the hybrid battery and supplies electrical power to drive motor generator two (MG2). In addition, by regulating the amount of electrical power generated (thus varying the generator's rpm), MG1 effectively controls the continuously variable transmission function of the transaxle. MG1 also serves as the starter to start the 1NZ-FXE engine. MG2 provides the torque and power that motives the Prius under light loads, as well as supplementing the engine during normal operation. It also converts the vehicle's kinetic energy that is generated through the activation of the regenerative brakes into electrical energy, which is then stored in the HV batteries.

    Inverter
    The inverter is an electric power converter that converts the direct current (DC) of the hybrid battery and the alternating current (AC) of the electric motors. The inverter also transmits information to the car's computer that is needed for precise current and voltage control. Because the hybrid battery is rated at DC 273.6 volts, the inverter is equipped with a converter. The converter is used for transforming some of the hybrid battery's power into 12-volt power necessary for vehicle accessories like the lights, audio system and the climate fan.

    Hybrid Battery
    The sealed nickel-metal hydride (Ni-MH) battery pack is mounted behind the rear seats. It weighs about 100 pounds. The battery pack consists of six 1.2-volt cells connected in series to form one module. A total of 38 modules are connected in series, thereby giving a total voltage rating of 273.6 volts. Toyota has installed a cooling fan to keep the battery pack at a constant temperature. The fan draws in air from air vents mounted on the top of the rear parcel shelf.

    Reduced Emissions Equipment
    The Prius is fitted with two three-way catalytic converters. On models bound for the U.S. market, an additional hydrocarbon absorber has been added for reduced emissions. Toyota installed the hydrocarbon absorber to reduce emissions at vehicle start up. Cars generally produce the most emissions at start up because the catalytic converters don't work well when cold. When the Prius is first started, a bypass valve activates and routes exhaust gasses into the absorber and prevents them from leaving the tailpipe. The gasses stay there for a short period until the catalytic converter heats up. After the converter has warmed up, the bypass valve opens, allowing the gasses to be released by the absorber and cleaned by the converter.

    The Prius' vapor-reducing gas tank is another feature designed to reduce the amount of emissions. You know how when you open the gas cap of a normal car and gasoline vapors rush out? That's because gas evaporates. And the more space that is available in the gas tank, the more vapors will be produced. These vapors are harmful to the environment, and they can escape even when the vehicle is parked or while driving. The Prius' tank utilizes a plastic liner, or bladder, inside the steel gas tank. As fuel is burned, the bladder collapses, minimizing the volume of the gas tank. With less volume, there is less room in which fuel can evaporate.

    Second Opinion

    Editor-in-chief Christian Wardlaw says:
    Toyota has built a better hybrid than Honda. Compared to the Insight, the Prius is more enjoyable to drive around town, is constructed of higher-quality cabin materials, resembles a passenger vehicle rather than a Star Wars escape pod, and easily carries four people along with a good portion of their belongings. Aside from these substantial benefits, Prius also costs less than the Insight.

    However, fuel economy suffers. During a test drive that included highway driving, city driving and mountain driving with two adults on board, the Prius struggled to maintain a 40 mpg average. Our Insight is currently getting 25 percent better fuel economy.

    But really, that is the only major shortcoming associated with the car. Well, that and the fact that when the gearshift is placed in drive, it completely blocks access to the stereo's tuning buttons, volume knob and on/off switch. Careless people could, as I did, accidentally bang the shifter into neutral, though not into reverse thanks to an effective lockout between R and D. This is a minor complaint. Toyota's attractive Prius proves that hybrids are here to stay.


    Technical editor Scott Memmer says:
    I'd been looking forward to driving this car for almost a year, ever since I read about it in various automotive publications around the beginning of the millennium. My curiosity was further piqued after I drove our long-term Honda Insight, which, even with its various styling and engineering oddities, intrigued me.

    Let me say at the outset: this is one impressive vehicle. Not only does it accomplish what a hybrid should -- great gas mileage, futuristic use of materials and technologies -- but the Prius is, in its own right, a pleasant enough conveyance with little to detract from it. I found myself smiling as I drove it. As if all that weren't enough, the Prius is a SULEV whereas the Insight is only a ULEV vehicle. So it lives up to its hybrid heritage. I could go on and on. If this car is as reliable as your average Toyota, the company has hit a home run. Get out there and put your name on a waiting list!

    Associate editor Liz Kim says:
    Sure, the Prius has its faults, namely the awkwardly placed shifter that blocks the radio controls and the exterior that looks like an Echo Ritalin-ed into submission. But ultimately all its peccadilloes can be pardoned by virtue of the fact that it's just more pleasurable to drive than a Honda Insight. With a roomy interior and much more solid road manners, I didn't feel like I was sacrificing much in order to help the environment. It was a shock to learn that the Insight has three more horses; somehow, in the Prius, I was able to pass cars at highway speeds, whereas in the Insight I had to carefully strategize my lane changes. Simply put, the Insight makes you feel like a martyr. The Prius makes you feel like a hero.

    Consumer Commentary

    On fuel economy:

    [Note that the first four posts in this section are from stevens4 over a period of several weeks - he also talks about driving performance.] "I was the first person to take delivery of a Prius in Kalamazoo, Michigan, seven days ago, on August 28. The dealership has nine more on order. The car is being driven at speeds up to 60 mph until 600 miles are reached per Toyota's new car recommendation. Today at 560 miles, the fuel light came on and 'beeped.' This resulted in the purchase of 10.1 gallons of 87 octane gas for an average city/highway fuel economy of 55.4 mpg for the first week. The tank was not topped off. The gas price here is presently $1.58 for 87 octane. The Prius delivered over 4 times better fuel efficiency (56 mpg vs. 13 mpg) over the former V-8 SUV, and traveled twice as far on 1/4 as much gas as the SUV. The luxury car like ride and near sports car like handling are astounding for a subcompact. Plus, it does it all at 55 mpg. The 258 pounds of torque from 0-400 rpm are all there. This past week, I drove the Prius up the area's steepest hills, on dirt roads, and on the interstate for a short interval. The car simply amazes. The lack of engine vibration is another benefit, reducing noise pollution as well as air pollution. This may reduce driving fatigue on long commutes." -- stevens4, "Toyota Prius, #295 of 445, Sept. 5, 2000

    "I've now driven my new Prius over 1,000 miles in southwestern Michigan and recently celebrated by getting a second tank of gas (8.3 gallons) for a total of 18.4 gallons of 87 octane gas purchased since getting the car in August. I went to the same gas station with nearly the same outside temperature as the first fill up. The combined city/highway fuel economy for the first 1,000 miles is 54 mpg. Readings to determine the mpg are from the odometer & gas pump at the time of fill up. I used to get 230-270 miles on 18 gallons in the V8 SUV. The Prius is delivering over three times greater distance on the same amount of fuel. In city driving it's over four times greater fuel economy." -- stevens4, "Toyota Prius," #334 of 445, Sept. 14, 2000

    "My new Prius has just reached 1,500 miles, and a third fill up (10.4 gallons after driving 505 miles), for a combined city/highway average of 52 MPG for 1,500 miles (28.8 gallons purchased since August). The quiet ride quality, superb handling and performance continue to amaze. Getting lots of favorable comments from people here in southwest Michigan. The Prius is saving us over $1,500 a year in fuel costs when compared to the former V8 SUV, and delivering greater performance, 58-65 mpg in the city, upper 40s on the highway." -- stevens4, "Toyota Prius," #358 of 445, Sept. 21, 2000

    "Today we drove 240 miles on the freeway across southern Michigan at an average speed of 70 mph. In heavy freeway traffic the Prius provides a solid ride with plenty of power available at all times, easily maintaining speed going up and down hills. During a stop in Indiana, we purchased 9.3 gallons of 87 octane gas, having traveled 485 miles since the last fillup, for a fuel cost of $13.00. The first 2,100 miles with the Prius have provided a 52 mpg city/highway average." -- stevens4, "Toyota Prius," #375 of 445, Sept. 28, 2000

    [Posts #421 and #422 go together.]
    "I took delivery of my Prius about three weeks ago and am averaging about 47 miles per gallon in city driving. I am not getting the rated 52 miles per gallon, which is a bit disappointing. I am driving on flat roads, and have been careful not to start or stop abruptly. Would other Prius owners please post their fuel consumption? Thanks." -- paul456h, "Toyota Prius," #421 of 445, Nov. 2, 2000

    "I, too, am getting 47.x mpg. I hover around 47.5 mpg. I have not yet had the car out on the highway. I average about 35 mph during my 10-mile trip to work each day. Still, I have driven the car everyday for more than a month now, have logged more than 600 miles on the car, and have had to put gas in the car just once. Quite a change from when I was driving my Caravan to work." -- gdoyle1, "Toyota Prius," #422 of 445, Nov. 3, 2000

    [Posts #333 and #335 go together.] "... I have a 120-mile round-trip commute, mostly highway (105 miles or so). According to the computer, I'm getting ~46 mpg. I drive with a 'light' foot, and stay within a couple of mph of the 65 mph speed limit. Just wondered what the 'real' story was with everyone's mileage. I would love to be in the 55+ mpg range, but know that it's probably impossible with my drive."-- shomrighausen1 "Toyota Prius," #333 of 445, Sept. 14, 2000

    "I have over 2000 miles on my Prius and have experienced a similar mileage confusion. The computer is constantly telling me I average 60 mpg between 475-mile fill ups. However, the fill 'n' spill method is telling me I am getting 43mpg. I do quite a bit of highway miles and city miles. Also is it just me or is anyone else here experiencing the following: My LCD screen display is CONSTANTLY freezing up where it stops showing where the power is going. At the same time, the outside temperature reading disappears. It is really frustrating. Otherwise I am still in love with this car." - davidfs,"Toyota Prius," #335 of 445, Sept. 14, 2000

    "Got MINE! (I love it.)Only getting 45 or so MPG with the first one-eighth of a tank, but that will probably get better. Only problem was the dealer put the center little hubcap on badly, so that it rattled. They fixed it this afternoon. Car behaves wonderfully. Wish it had a fuel cell instead of gas motor!" - jludwi2, "Toyota Prius," #383 of 445, Oct. 2, 2000

    On performance:

    "I haven't done any timing for 0-60, but I can tell you that this car will hold its speed for extended periods of time. I've taken it out on the interstate, and kept it in the 75-80 range for about two hours. Mileage suffers if you are going at this speed (in the low 40s), but it is still better than any other car that I've driven. Another thing that I've noticed at 'highway speeds' is that the CVT gives great 'passing' power and acceleration. About 70 to 80 percent of my commute is 65 mph plus driving, and I've averaged 46 mpg over the last 2,000 miles." -- shomrighausen1, "Toyota Prius," 376 of 445, Sept. 28, 2000

    "I received my Prius on August 16. Most of my driving [has been] on I-10 and I averaged about 50 mpg over 375 miles. Although I have held the speed down to 60 mph as directed, I have had no problems with inadequate acceleration." - sheine, "Toyota Prius," #254 of 445, Aug. 21, 2000

    On the electric battery:

    [stevens4 writes in response to participants' concerns about battery discharge - incited by a Motor Trend article] "I've driven my Prius across southwestern Michigan on the freeway at 70 mph with no loss in battery power or capacity. Last year Toyota brought the Japanese version of the Prius to the U.S. for evaluation. Following the evaluations Toyota increased the engine(s) power to overcome long distance travel limitations. I'm getting between 58-65 mpg in the city, upper 40s to low 50s on the highway. There hasn't been any battery power loss on the long distance cross-country freeway drives. After 1,700 miles, we're getting a combined highway/city average of 52 mpg, traveling twice as far on 1/4 as much gas as the former V8-SUV, and saving over $1,500 a year in fuel costs." -- stevens4, "Toyota Prius," #368 of 445, Sept. 26, 2000

    On braking:

    "The brakes feel different because of the regeneration effect. I've noticed that they seem a little light at highway speeds. In-town speeds are another story - you can stop in a hurry! I remember reading somewhere that the 60-0 distance is 137 feet. It might take longer than some cars from 60-45, but I don't know that there are too many cars out there that could out-brake one of these." -- shomrighausen1, "Toyota Prius," #343 of 445, Sept. 18, 2000

    Potential problems:

    [This is an owner from Ontario (other posts from him below) whose Prius had a power steering failure. This person hasn't posted since. However, we checked the NHTSA site, and there is only one recall for the Prius and it is for exactly this problem.] "Earlier this week we noticed and raised an 'observation' about the Prius when in park with the car in 'ready' (started). Whenever the gas engine kicks on the car moved forward slightly. No biggie, just something we hadn't noticed before (not sure if it has always done it?). Dealer told us no one else had mentioned it but also said only one other person had the car since we got ours. (We were the first to take possession.) This afternoon, while driving we noticed a moderate intermittent shudder in the steering wheel. [I] try to determine when/where it occurs, i.e., while braking, etc., but can't isolate it to any particular thing we are doing. [I] call the service department at our dealership and ask about having someone check it first thing Tuesday since it is too late today, but they are booked up [for Tuesday].

    "Helpful guy tells me to check the power steering fluid. I said I 'thought' the car had 'electric assist' steering, but the service guy said no. Ok, I get off the phone, get the manual, open the hood and say where the H is the PS reservoir. Hmmm, nothing listed in the manual under specs for PS fluid! OK, I call service back, talk to the same guy, tell him I can't find the reservoir, he says to hold while he checks with someone. That person comes on the line; FORTUNATELY, I know this guy knows about the PRIUS. He says, 'no the Prius doesn't have a PS reservoir - it IS electric.' He asks if we have any warning lights, nope. OK, we'll bring it in on Tuesday. Hang up the phone. Start the car, WARNING lights everywhere. Major fault light to left of speedo. Warning screen on LCD with PS icon highlighted in red. Call my bud back and say we have warning lights now. He says he will check manuals and call me back. (This is very close to closing time, so it was great they would do ANYTHING this time of day before a long weekend!)

    "Calls me back, (in the meantime, I restart the car and no faults), he says they would need to check which codes have come up and do some diagnostic work and [that I should] bring it in first thing Tuesday even though he isn't in the Prius tech is. If it fails over the weekend, he said they don't want to have us stranded, so get it towed to them and rent a car and they will pay for it. Fantastic. Have had the car for 4 weeks and one day, 2200 km. The ONLY thing that bothers me is the erroneous info the first service guy told me when I told him we had a PRIUS. I am certain TOYOTA wants to quickly identify ANY problems with these cars ASAP so I think it should be clear that only PRIUS authorized staff should handle PRIUS calls.

    "I won't make the same mistake asking someone other than the staff I know have the PRIUS training. Another oddity that we noticed that I seem to recall was just discussed was the PRIUS moving backward on a slope (like a standard with the clutch in). When we got the car home, stopped on a slope in drive, let the foot off the brake and it rolled back several feet. Not sure if someone mentioned this as normal. We aren't taking all this too seriously it is just kind of funny things go wrong on the Friday before the long weekend. Just sharing info not trying to bash the PRIUS cause we still love it." - ontariocaprius, "Toyota Prius," #284 of 445, Sept. 1, 2000
