Buying An Estima Hybrid

What to look for when buying an Estima Hybrid ( 2002 - 200X )

Model : AHR10W
Dimensions : 4800L 1800W 1760H
Year Manufactured : 2002 - 200X
Petrol Engine  :  2400cc
Electric Motor : 13Kw front,  18Kw rear
Transmission : CVT
Battery : 208.8 volts, 50 Kg
Weight : 1950 Kg
Fuel Economy : 14 Km/L



For those who don't know anything about and have never driven a hybrid - BEWARE.
Buy from a reputed dealer and one who knows and can support this new technology.
A hybrid is a great and reliable vehicle but because the electric motor and the petrol engine have to work together problems in engine side will affect the battery.

The Estima Hybrid is a 4 wheel drive vehicle. The rear wheel is powered by the 18Kw electric motor. Without a strong battery the vehicle will feel very much under powered. You can also damage the CVT transmission and engine if the battery is weak.

The Estima Hybrid is a 7 seater or 8 seater van but fuel consumption is half that of a regular petrol version Estima. There have been 2008 Estimas sold at auction in Japan that have done 600,000 Kms. This shows that when all parts are working correctly they are quite trouble free.

Look for the following
1) Vehicle must have a good reconditioned battery and a Power Jockey Installed.
Hybrid batteries last between 7 - 10 years. By now if the battery has not been reconditioned and a Power Jockey installed, the battery will soon fail and the car will be inoperable.




2) Check to ensure that the vehicle is fully maintained and serviced.
     Spark Plugs : 20,000 Kms if Irridium 100,000 Kms
     MAF Sensor : 80,000 Kms
     Oxygen Sensors : 120,000 Kms
     Service parts wear out and have to be replaced for the vehicle to operate efficiently.
     If possible a scan should be done to ensure that the sensors are working correctly.

If you take care to inquire about these two aspect of the vehicle, you can be assured that the vehicle will work for many years. The Battery Clinic assures us that the battery pack can last the life of the vehicle with the occasional battery repair and cell replacement every 2 to 3 years costing about $400.

The Petrol engine is tough and very reliable. It should be able to clock up 500,000 Kms and still show little wear and tear. For one the engine does not work all the time and it red lines at 4000 RPM compared to a normal petrol engine at 8000 - 12,000 RPM. Wear and tear compared to a standard vehicle is less than half.

The Electric motor will easily last the life of the vehicle. In 6 years of working with these vehicles I have not seen any motor fail.

Spare parts are available from wreckers and are well priced. Don't fall for those astronomical prices quoted for new parts by Toyota dealers. They are priced not to sell.

Buying A Generation Three Prius

What to look for when buying a Generation Three Prius Hybrid ( 2003 - 200X )
Model : NHW20
Dimensions : 4445L 1725W 1465H
Year Manufactured : 2003 - 200X
Petrol Engine  : 76Hp, 1500cc
Electric Motor : 67Hp,  295 Nm torque
Max RPM : 5000, ( 0 - 100 ) 10.5 Secs
Battery : 201.6 volts, 45 Kg
Fuel Economy : 22 Km/L or 4.8L/100Kms

For those who don't know anything about and have never driven a hybrid - BEWARE.
Buy from a reputed dealer and one who knows and can support this new technology.
A hybrid is a great and reliable vehicle but because the electric motor and the petrol engine have to work together problems in engine side will affect the battery.

The Generation 3 Prius is a hatchback. It is a little longer and wider and more powerful than the Generation 2. As the new modular cell packs are used, these are easily available and there is no issues in getting replacement cells for the foreseeable future. The generation three cost a few thousand more than the Generation Two but if your budget can accommodate the extra cost it will be worth it.

As the battery voltage is boosted to 500 volts a weak battery reduces the boost voltage available and increases the current which can damage the inverter. It is important to ensure that the battery is always in good working order.

Look for the following
1) Vehicle must have a good reconditioned battery and a Power Jockey Installed.
Hybrid batteries last between 7 - 10 years. By now if the battery has not been reconditioned and a Power Jockey installed, the battery will soon fail and the car will be inoperable.

Toyota aims to remain King of the Hybrids - NYT

Toyota Aims to Remain King of the Hybrids

E-mail Print PDF
CAR070111As Toyota heads to the Detroit auto show that opens Monday, the company aims to burnish its reputation as a leader in environmental technology - an image increasingly under threat from resurgent rivals. Both Nissan and General Motors have been promoting their new electric-powered vehicles, which began reaching consumers last month. And Ford, which will start selling an all-electric version of its popular Focus compact later this year, will use the Detroit show to promote its green credentials.
As Toyota works at the Detroit show, it will be trying to convince customers that there is still mileage in the gas-electric hybrid technology it pioneered more than a decade ago with its Prius. The Prius, the world's first mass-produced hybrid car, accelerates and runs at low speeds on an electric motor and batteries, with a gasoline engine kicking in at higher speeds.
In ads on television and YouTube, Toyota has been previewing a new addition to the Prius lineup that it will introduce at the auto show. "I can't show you everything just yet, but here's a sneak peek," a skateboarder says in one of the ads as he zooms past a car shrouded in a black veil, which billows up just long enough to reveal the car's outline. Toyota might be on the defensive, if only because of its many reputation-tarnishing recalls in the last year. But the automaker is particularly vexed to find itself having to restate its credentials as the industry's environmental leader, something it has had little trouble claiming since it introduced the Prius in 1997.
Nissan, one of Toyota's main Japanese rivals, calls its new battery-powered Leaf hatchback the world's first mass-produced, all-electric vehicle. Its ad campaign for the United States features a polar bear running from a melting ice cap to hug a Leaf owner in a big city meant to evoke San Francisco. The tag line: "Innovation for the planet, innovation for all." A resurgent G.M., meanwhile, is claiming a breakthrough with the Chevrolet Volt, a plug-in hybrid that runs on rechargeable batteries for up to 50 miles before a gasoline engine kicks in. Last month, at the Economic Club of Washington, G.M.'s chief executive, Daniel F. Akerson, called the Toyota Prius a "geek-mobile" that he would never want to drive.
But Toyota, even as it emphasizes the company's environmental record, is skeptical of all-electric vehicles. It remains committed to the hybrid technology, which it has spent at least $1 billion to develop. By the end of 2012, the company plans to introduce six new hybrid vehicles and says that all its models will come in hybrid versions by 2020.
"Customers are going to ultimately decide what kind of car they want to drive," said Keisuke Kirimoto, a Toyota spokesman based in Tokyo. "And whatever customers choose, we will be there."
The Prius has already exceeded Toyota's own expectations. In 2005, the company said it hoped to sell a million of the hybrid vehicles worldwide over five years; by September 2010, it had sold twice that many. And within Japan, helped by generous tax incentives, the Prius has been the country's top-selling car for the last 19 months.
Earlier this week, Robert S. Carter, Toyota's vice president for United States sales, told analysts that the company expected the Prius to become its best-selling car in the American market by the end of the decade.
And Toyota's top executives are quick to highlight the uncertainties surrounding purely electric vehicles. "We still predict the spread of electric vehicles will be extremely slow," Atsushi Niimi, an executive vice president at Toyota, said at a year-end briefing.
Many analysts share Toyota's skepticism. J. D. Power & Associates, the market research company, predicts that in 2020 only 1.3 million of the 70.9 million cars projected to be sold worldwide that year will be all-electric - fewer than 2 percent. Even optimistic analysts put the figure at no more than 5 percent.
The concerns include low horsepower, the reliability of electric technology and the prospect of the charge running out while the car is being driven. Although battery technology has improved in recent years, both nickel-metal hydride and the more powerful lithium ion batteries remain bulky, vulnerable to heat and expensive to produce. The price premium of an electric car over a gasoline one could also deter consumers, if gasoline prices continue to hold fairly steady.

Still, some analysts say Toyota risks losing its edge if it does not keep abreast of advances in zero-emissions technology.
"It is dangerous for Toyota to insist on sticking to its hybrid-focused strategy," said Yasuaki Iwamoto, an auto analyst at Okasan Securities in Tokyo. "Just like it was a leader in hybrid technology, it should be jumping out in front in electric-vehicle technology," he said. "If it doesn't, it will be difficult for Toyota to regain its image as a leader in the environment space."
By at least one measure, Toyota has not lost that image in the first place. According to Consumer Reports' 2011 Car Brand Perception Survey, released on Wednesday, Toyota is the leader in the "environmentally friendly/green" category, which the survey says helped it hold onto its title as the most recognizable car brand in the United States. Without Toyota's big ratings in the green category, Ford would have claimed the overall top score, Consumer Reports said.
While it remains committed to hybrids, Toyota is hedging its bets on electric technology. In late 2009 it developed and started leasing a small number of its own plug-in hybrid vehicles, which have a range of about 13 miles before the gasoline engine starts. The model is scheduled to go on sale next year.
And last May, Toyota invested $50 million in the Silicon Valley electric car start-up Tesla Motors. It signed a separate $60 million deal with Tesla to develop a fully electric vehicle to run on lithium-ion battery packs. The two showed off a prototype at the Los Angeles Auto Show in November.
Toyota is also developing its own tiny all-electric vehicle, which it says it will begin selling in 2012. But the company takes pains to say the battery-powered car will serve a niche market of drivers making only very short commutes.
Toyota, however, needs more than niche markets to help it after a year marred by recalls of some 11 million vehicles - including the Prius - for faulty gas pedals, floor mats that could trap accelerators or braking and engine defects. Those flaws, as well as Toyota's handling of the recalls, have tarnished its reputation for safety.
Toyota's sales in the United States have suffered as a result. Earlier this week the company reported declines for December and for all of 2010, saying sales fell 5.5 percent last month from a year earlier and 0.4 percent for the year. That made Toyota the biggest loser in a recovery year for the overall United States auto market, which grew 11.1 percent in 2010 from a year earlier to 11.6 million cars, according to the research firm, Autodata.
That is why so much is riding on Toyota as it heads to the Detroit auto show.
"Last year, we caused people a lot of concern," Toyota's chief executive, Akio Toyoda, said on Wednesday in Tokyo. "But we also learned a lot," he said.
Asked by the public broadcaster NHK to think of a word to describe Toyota's strategy for 2011, Mr. Toyoda smiled.

Prius Starts Stutters then Stops

Prius Generation 2. -

1) A common problem we see in this model is the throttle body sticking. Leads to poor performance and poor fuel consumption. Freeing up the spring mechanism fixed the problem.

2) Vehicle starts up stutters then stops. The cause could be carbon built up in the exhaust. Blowing the exhaust system out may fix the problem. Another cause could be excess oil in the throttle body. Can be seen if you remove the air filter. Pour some petrol down to dissolve the oil and start the vehicle. This may solve the problem. Oil deposit was caused by excess oil in the engine from overfilling.

All the above problem will affect the battery causing it to fail. Proper servicing from knowledgeable technicians about hybrid vehicles will save money in the long run.

A Very Good Car

I remember many years ago while stopping at traffic lights I often wondered to myself how good it would be if the engine can turn itself off. I personally know of people who actually turn their engine off to save fuel! This is false economy as it takes more fuel than you would save when starting the vehicle again.

Well today the hybrid vehicle does it as a matter of course and not only that - it saves energy from braking to release when required and turns the engine off when cruising as well.

Just how good is the Hybrid car when compared to a standard vehicle?

1) Fuel Economy
A well maintained Generation one Prius ( 1997 - 2000 ) still return 20 - 22 Kms to the litre (4.5L/100Kms) This is after clocking up more than 200,000 Kms on the odometer! A standard vehicle would have loss so much compression that it's fuel economy would have deteriorated at least 25% from new.

You can still purchase a good used Generation one Prius for $6000.  If you are currently spending $100 on fuel a week, you could save $2500 a year. This means recouping the cost of your purchase within 3 years at the most. This savings alone should sway thinking people towards purchasing a used hybrid, especially if you have to drive good distances going to and from work.

Generation two Prius (NHW11)  are even more economical and Generation three (NHW20) even better still.

2) Internal Combustion Engine

This engine shuts off when not required. This means that the odometer reading does not represent the actual wear and tear as an engine in a conventional car. My guess is that if we half the odometer reading it would represent the actual wear and tear when compared to a conventional car.

The engine oil in a vehicle that has done 150,000 kms, is still golden a month after an oil change. This means that the piston rings are still intact.

3) Starts every time

One thing I noticed was that the hybrid car will start every time as long as the HEV battery and 12 volt battery are in good working order.
In 12 year old conventional vehicles starting is always questionable as it depends on the state of the 12 volt battery, the starter motor, the alternator, the idling, the timing chain and the distributor. Most of these components are not used in the hybrid car - Less parts to go wrong therefore starts every time.

4) Smooth Quiet and vibration free ride

Although it can best be described as medium saloon, It drives like a large saloon. The combination of the electric engine and the petrol engine contributes to this smooth ride. Being quiet and vibration free adds to the comfort of driving a hybrid.

5) Brakes pads

Regenerative braking recovers the energy from braking which are then stored in the batteries for reuse. This means that the brake pads are not used in normal braking. Most hybrids even at 150,000 Kms still have their original set of brake pads.

6) Spark Plugs

I have personally taken a set of spark plugs out of a car that has done 150,000 Kms. The gap was so large that it stopped firing in one cylinder.

All this goes to show that cost of mechanical maintenance is much lower than a conventional vehicle.
