There are two important facets to an efficient hybrid:
1) An efficient machine, and
2) an efficient driver. Working in unison, they can dramatically enhance fuel economy.
Eco Assist™[1] is composed of two basic functions:
* A sophisticated feedback system that teaches you to drive more efficiently[2]
* An ECON button[1] that helps aid in optimizing your vehicle’s fuel efficiency if used in conjunction with responsibly efficient driving practices[2]
These components can work individually or in tandem to help boost your overall fuel economy. As the EPA tests have shown, the Insight is capable of excellent fuel economy without any special techniques. Utilizing the tools of Eco Assist™[1] can help you make the Insight more efficient. For a demonstration of how Eco Assist™[1] works, watch the video.
This video provides a full explanation of the technology behind the Honda Insight Eco Assist™ system and explains how the system can coach you to drive more efficiently.
1) Turn off ignition switch and remove key (if so equipped). This turns off the engine and the motor, which prevents electric current from flowing into the cables from the motor or high-voltage battery, and, turns off power to the airbags and the seatbelt pre-tensioner.
2) After turning off the ignition switch, it is recommended that emergency responders remove the key (if so equipped) so the car cannot be inadvertently restarted. To let everyone at the crash scene know the key is removed, give the key to the I/C, who will make a general announcement regarding the key. At this point, the high-voltage system has been isolated. This improves responder safety in and around the vehicle.
3) The next step is to shut down the 12V electrical system on the hybrid just as we typically do on any conventional vehicle involve din an MVA.
4) Locate the 12V battery. It may or may not be under the hood. In the Toyota Prius it is located inside the driver’s rear wheel well within the trunk. Either disconnect or double cut first the negative and then the positive cable. This disables the high-voltage battery controller, which prevents electric current from flowing into the orange cables and the high-voltage battery.
5) With the ignition key turned off and removed and the 12V battery disabled, the hybrid vehicle is safe to work on for vehicle rescue. High-voltage electricity still exists, but it is isolated to the battery pack, generally in the trunk of cars or under the rear passenger seat in pick-ups.
6) An alternative to disabling the 12V battery is to remove the HEV fuse, generally located in the engine compartment junction box. When in doubt pull all fuses in this box.
7) Stabilize the vehicle. Crib at four points directly under the front and rear pillars. Do not place cribbing under high-voltage power cables, exhaust system or fuel system.
8) At this point conventional rescue techniques may be used, including cutting of door hinges, modified dash roll, steering wheel displacement, etc. However caution must be used at all times to avoid cutting any high or intermediate-voltage lines.
9) Should a hybrid be involved in a rollover, end up on its roof, this may prevent access to the engine compartment and disabling of the 12V battery may not be possible. This poses a serious threat. If access to the 12V battery is not hindered, extrication can be handled as in any conventional vehicle rollover.
10) The removal of the roof of hybrids such as the Toyota Prius may be easily accomplished by opening the hatch to gain access for cutting of the pillars. The hatch will need to be opened manually with pry tools because 12V power is needed to open the hatch.
11) Hybrid identification tags are located in the rear and/or sides of the vehicle. Severe impacts in these areas could destroy or hide the identification tags. You must be sure to look for other hybrid identifications, make sure you are aware of the models on the road, and when in doubt assume the vehicle is a hybrid until proven otherwise.
FIRE
1) A fire involving a hybrid vehicle can be handled by following normal vehicle firefighting procedures. In a typical vehicle fire incident, the engine compartment, interior of vehicle or trunk area are burning. By following generally accepted fire suppression guidelines, crews attack the fire with an adequate water flow rate, working from a safe position of approach.
2) SCBA is worn throughout the incident.
3) The initial fire attack should be a fast and aggressive attack.
4) Fire crews may not be able to identify a hybrid until the fire has been knocked down and overhaul operations have commenced.
5) The wheels should be chocked as soon as safely possible.
6) During overhaul, the same steps defined in the extrication module should be used to disable the high-voltage system. (shut down power, disable 12V system)
7) Fire suppression crews will not be shocked or electrocuted during attack on a hybrid vehicle fire, even if flames are impinging on the battery pack itself.
8) There are potential, unique problems involving fire situations with hybrid vehicles. Any fire where there is direct flame impingement on the high-voltage battery pack would be an example. A fire that has originated within the battery pack itself or an electrical fire that begins somewhere within the high-voltage electrical system would also require special precautions.
9) Radiant heat could cause the modules inside the high-voltage battery to melt just as any plastic material would exposed to high temperatures. If heated sufficiently, it is possible the plastic casings could melt down, exposing the inner components of the high-voltage battery.
10) Copious amounts of water should be used quickly to eliminate radiant heat to the battery box and begin cooling the plastic battery cell modules in the high-voltage battery pack itself.
11) Should a fire in the Ni-MH HV battery pack occur, the I/C will have to decide whether to pursue an offensive or defensive.
12) If a melted nickel metal hydride (Ni-MH) battery is encountered, the I/C may want the nearest dealer of the vehicle notified to send a designated battery recovery specialist to the scene to deal with the damaged battery.
13) In the Ni-MH Product Safety Data Sheet, responders are advised that virtually all fires involving Ni-MH batteries can be controlled with water. The information sheet also recommends “In case of fire where nickel metal batteries are present, apply a smothering agent such as METL-X, sand, dry ground dolomite, soda ash, or flood the area with water. A smothering agent will extinguish burning nickel metal hydride batteries.”
14) Class D extinguishers are the recommended extinguisher to use with Ni-MH batteries. But…….
15) Not all Class D extinguishers are equal. Some contain particles of metal such as copper. Copper, for example, is one metal that may actually cause an adverse reaction with the high-voltage battery and generate hydrogen gas. In a small space, such as a trunk, this could cause an explosion.
16) Large amounts of water will not be able to directly attack a fire burning inside the battery pack unit itself. The metal cover of the pack prevents a direct attack on the internal cells of the battery. The water application, however, will cool the adjacent battery cells. Burning Ni-MH batteries will burn themselves out. Applying sufficient amounts of water will cool the metal housing of the battery pack and control the fire until the battery modules that are actually on fire burn themselves out. DO NOT EVER REMOVE THE COVER OF THE HIGH-VOLTAGE BATTERY PACK!
17) When water is used to extinguish Ni-MH battery fires, some hydrogen gas may evolve. In this situation ventilation will be needed to prevent a build up of the gas. Leaving the trunk, hatchback or battery compartment cover open is advised to ensure ventilation of the gas. If there is a concern that hydrogen gas is present, and ventilation is not possible, fire smothering agents are recommended.
18) A battery fire WILL produce toxic fumes, including oxides of nickel cobalt, aluminum, manganese, lanthanum, cerium, neodymium and praseodymium. Because of this, SCBA must be worn throughout the fire attack and during overhaul.
19) In addition, keep the “hot zone” clear of unnecessary personnel. Keep all “hot zone” personnel fully protected with structural clothing that addresses Level 3 hazmat personal protective clothing criteria and SCBA.

Question: What about the battery life of a hybrid car?
Batteries used in hybrid cars prove quite expensive while replacing them. However the car engineers have been successful in designing these batteries in a way that they would last as long as the lifetime of the car. Most of the hybrid car manufacturers give the warranty of eight to ten years and this is quite a long period for the car battery to last. You would be surprised to know that Toyota hasn’t replaced a single battery pack for the popular hybrid Prius since it was brought on the market in 2000.
Question: What makes a hybrid car more expensive than the conventional car?
Hybrid cars cost a few thousand dollars more than their conventional counterparts. The price of the hybrid car increases because of the costly batteries introduced in them and two engines in place of one. However, if we consider the purchase in the long run, hybrid cars prove much cheaper than the conventional cars if the total fuel consumption is taken into consideration.
Question: Is a hybrid car slower than the conventional car?
Hybrid cars are by no means slower than the non hybrid counterparts. In fact most of the hybrid cars these days attain more than 100 mph of the maximum speed which is more than enough for many people.
Question: How to recharge the hybrid battery?
There is no need to plug in the batteries in the hybrid cars in order to charge them up. In fact they are charged in the normal course of the drive. During braking and coasting the extra energy released gets converted into electricity which recharges the battery.
Question: How does cold weather affect the performance of hybrid cars?
Generally car battery doesn’t work well at low temperatures; but in most of the hybrid cars thermal management system is introduced to cope with the problem and so the car battery gets charged up as soon as you start the car. When the car battery attains the normal operating temperature which happens pretty fast, the car can perform well even at lower temperatures.
Question: What about driving hybrid car in hot weather conditions?
Driving a car in hot weather conditions is a tough ask indeed. There are a few automobile experts who doubt the safety involved in driving hybrid cars. According to them high voltage batteries used in hybrid cars can be very dangerous in hot weather conditions as there are chances of catching fire quickly. They also say that if a car meets with an accident, the car will catch fire so fast that it would be very difficult to rescue people travelling in the hybrid car. However, this criticism doesn’t hold good if we consider the fact that most of the hybrid cars have performed pretty well in the southern part of the U.S.A. like Florida, Arizona or Texas. As regards the high voltage battery pack, it has the thermal management system to control the heat inside. When the battery gets hot after a certain limit, the system will shut it off automatically; thus saving it from any untoward incident.
Question: What are ‘Green Vehicles’?
Hybrid cars are popularly known as green cars on account of their eco-friendly characteristics. These are the cars with low emissions which imparted them the status of eco-friendly vehicles. Hybrid cars are rapidly emerging as a promising option and a feasible solution to the fuel problems of the world. The fewer and cleaner emission of hybrid cars is an important characteristic of hybrid cars. These cars are known to lower the noise pollution level as their engines go on generating the necessary amount of horsepower without much roaring. When you switch the car on the electric mode, the car is virtually silent even when set in motion. Green vehicles indeed, aren’t they?
While global warming has become a serious environmental issue, using a hybrid car is a wise option to cope with the situation. Reduction in smoke and the emission of pollutants because of the hybrid cars will certainly prove ecologically beneficial.
Question: Is hydrogen fuel cell technology posing a threat to hybrids?
According to many auto experts, cars powered by hydrogen won’t pose any threat to the sales of hybrid cars for at least ten to twenty years to come. The first set of hydrogen powered cars will have a single energy source and so hybrids will be a far better option.
Question: What encouragement is given to promote the use of hybrids?
In many countries use of hybrid cars is being encouraged by the governments. There are many schemes initiated by the governments to promote the use of hybrid cars. For instance, in the United States of America, you get some tax benefits if you buy hybrid vehicles. In some countries the road traffic departments allow hybrid car owners to park their vehicles free of charge. There also are some specially built roads only for hybrid cars. These perks certainly encourage the potential car buyer to go for a hybrid car.
As with many of Toyota’s vehicles, the Prius has become a standard-bearer in its segment. While many automakers have yet to even develop a gasoline-electric hybrid vehicle, Toyota is already on its third generation of the Prius. This four-door hybrid has become a hit with consumers because of its stellar fuel economy, relatively uncompromised driving and acceleration characteristics and reasonable price.
The Toyota Prius (its name comes from Latin and means “to go before”) exists as a partial solution to the automobile’s problem of tailpipe emissions. The Prius, like other hybrid vehicles, has a special powertrain that combines a gasoline-fueled internal combustion engine with an electric motor. This powertrain, along with other advanced features, allows the Prius to deliver higher fuel economy and lower emissions compared to regular cars.
Due to its popularity and relatively long sales history, Toyota’s original hybrid car is a strong candidate for a shopper interested in a used hybrid vehicle. So far, it seems Toyota’s reputation for reliability and durability is holding true for the Prius. Early concerns about long-term durability have turned out to be mostly unfounded. However, potential buyers of a used Prius should take extra care during the research process. As the Toyota Prius is quite complex, future repairs and part replacements could be quite expensive.
Current Toyota Prius
The Toyota Prius was completely redesigned for 2010. However, it remains a four-door hatchback that seats five people. The car’s hybrid powertrain consists of a 1.8-liter gasoline engine that produces 98 horsepower and 105 pound-feet of torque that’s used in conjunction with two electric motors and a special planetary gearset that functions as a continuously variable transmission (CVT). Total system power is 134 hp.
Under full acceleration, both power sources work together to provide maximum oomph. But under lighter load conditions such as stop-and-go traffic, the Prius alternates between the two, often running on battery power alone. This maximizes the car’s fuel economy potential. A regenerative braking system converts energy normally lost as heat into electricity to charge the car’s battery pack. The current powertrain is a little more robust on the highway than the previous-generation car, although not really any quicker away from a traffic light. It is more fuel-efficient, however, with an EPA combined fuel economy estimate of 50 mpg — which is tops in the hybrid game.
Other changes for this new model include a more sculpted take on the iconic hybrid shape established by its predecessor. The interior was given a more radical overhaul, with a more conventional center control stack than the old car. The hybrid system display now resides high up on the dash next to the digital speedometer, while stereo and climate controls are laid out in a traditional manner with physical buttons rather than a touchscreen (which reappears if you order the optional navigation system). The result is a car that’s easier to acclimate to. It’s also a bit more comfortable for taller drivers, thanks to a height-adjustable seat and a telescoping steering wheel.
One thing that hasn’t changed is the Prius’ superb interior packaging, which helps extends the car’s appeal beyond simple fuel efficiency. Its hatchback body style allows for an impressive amount of cargo to be lugged around, while a surprisingly commodious backseat makes it a plausible replacement for a family sedan or compact SUV.
In reviews, we’ve found the current Toyota Prius to build upon its revolutionary predecessor’s successful formula of fuel efficiency and versatility. It’s now a more normal car to drive and use, making it easier to transition from a traditional car. While Honda’s less expensive but smaller Insight is worth a test-drive, those looking for a hybrid should still start their search with the Toyota Prius.
Used Toyota Prius Models
The second-generation Toyota Prius was produced for the 2004-’09 model years. It sat five people in a four-door hatchback body that provided extra versatility in terms of carrying items. This Prius’ hybrid powertrain was the same in concept as the current third-generation model, but it featured a smaller, 1.5-liter gasoline engine that produced 76 horsepower and 82 pound-feet of torque. With the electric motor spinning out power, peak net hp was 110.
Aside from its hybrid system upgrades, most buyers will find the interior to be the biggest area of difference between the second-generation model and the current Prius. The dashboard and controls were unconventional and futuristic, with stereo, climate, vehicle system and optional navigation controls residing in a touchscreen interface. There were steering wheel buttons for frequently used items, but ultimately, too much was put under the jurisdiction of the touchscreen (which could wash out in sunlight). The odd gear-selector action of today’s Prius was carried over from this generation, but then it was mounted on the dash. Another important difference to note is the lack of a telescoping steering wheel and height adjustment, making for an even more awkward driving position for taller people.
During its successful tenure in Toyota’s lineup, this second-generation Prius received minor changes. For 2006, a back-up camera, leather upholstery, leather-wrapped steering wheel and an auxiliary audio jack were added to the options list. A Prius Touring model was added the following year with a slightly firmer “sport” suspension, different 16-inch alloy wheels, a larger rear lip spoiler and several optional items. Side and side curtain airbags also became standard across the board. A “standard” trim level, which lacks cruise control and heated mirrors but in exchange had a significantly lower base price, was added for 2008.
In reviews of the Toyota Prius, our editors have cited outstanding mileage, ultralow emissions, hatchback utility and a reasonable price as the car’s greatest strengths. Downsides include soft handling characteristics at highway speeds and, compared to regular midsize sedans, unimpressive maximum acceleration. Most Prius owners say their cars typically achieve real-world mpg ratings in the mid-40s.
The original Prius debuted in the North American market for the 2001 model year. However, Toyota had been selling it in Japan since 1997. This model was the second hybrid vehicle available to U.S. consumers after the Honda Insight. In just about every aspect, the original Prius has been eclipsed by the second-generation car. The first-generation Toyota is slower, smaller and not as comfortable. But this in no way means that it is to be avoided. For a consumer interested in a used and affordable hybrid vehicle, this first-gen Toyota Prius could be a smart choice.
Though less advanced than those in the newer generations, the older Prius’ powertrain still paired a gasoline engine with an electric motor. Its 1.5-liter four-cylinder engine made 70 hp at 4,500 rpm and 82 lb-ft of torque at 4,200 rpm. The electric drive motor was worth another 44 peak hp.
Selecting a used Prius based on year shouldn’t be too difficult. Models built for 2002 and ’03 might have more of a draw, as it was then that Toyota started to offer additional optional features, such as a navigation system, side airbags and cruise control. Most first-generation owners seem quite happy with their cars and overall reliability has been very good.
