Toyota aims to remain King of the Hybrids - NYT

Toyota Aims to Remain King of the Hybrids

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.

Questions and Answers on 4 different hybrids

Q1.  I have a Prius in America - 2001. 138,000 miles, never had a problem until now - the inverter/converter went out. Toyota dealer mechanic estimates $4,200 to replace and possibly will have to buy new battery (another $2,300). trying to get advice - is it worth fixing or probable to have more expensive repairs down the line; is it possible to find usable converter/inverter part from salvage yard?

A1.  My guess is that it is the battery. I have never known of an inverter converter failure. My guess is that replacing the battery will fix the problem. The part on the inverter is just extras for doing nothing. We will of course repair the battery and fit the Power Jockey for less than the cost of the battery.

Q2. I have a 2007 Camry Hybrid with 36,200 miles. Took it to a Toyota dealer who did a diagnostic, which stated that the converter/inverter component needed a replacement. Cost to repair if not on warranty for the component would be $8000.

A2. Another converter/inverter. By putting up these problems Toyota is really shooting themselves in the foot.  I cannot diagnose the fault but again it would be very unlikely that it is the battery. Since it should still be under warranty - let them replace the inverter /converter!!


Q3. I have a Alphard hybrid, 2006, bought directly from Japan. I seem to have a loss of fuel mileage and wonder if there maybe something wrong. Using about twice as much fuel.

A3. If it is still running the battery should be OK. It will most likely be something in the ignition and fuel system.

Q4. I have a grey import NHW10 prius fault codes c2678-c2679-c2680 & subsequently no run situation. please advise.

A4. C2678 - Battery system failure.
       C2678 - HV battery failure
       C2680 - ILK disconnection

The first 2 codes means the battery has failed. So you will need to get it repaired. No point replacing as it would cost more tham the car is worth.
ILK Disconnection - means that the computer have disconnected the battery from the drive train. This car is no longer mobile. The engine will go into a high rev mode going nowhere.

Will hybrid cars replace gasoline cars?

In the Prius the gasoline engine has been stripped off many all it's usual moving parts that break down routinely such as the starter motor, distributor cam belts and much more making it a very efficient unit with little that can go wrong - engine wise.

Many cars have been driven for up to 10 years and more with nothing more than oil change, every 2 years and spark plugs only once in that time. This is possible because the engine don't run all the time, possibly only for half the distance the odometer clocked up as in cruise mode and at low speeds the engine does not operate. When it does run it is also at much lower RPM than regular gasoline engine. One would expect the hybrid vehicle to have a much longer useful life than normal gasoline vehicle, except for 1 flaw - The Battery.

After 10 years the battery can cost more than the value of the vehicle to replace. With existing  average age of a country's vehicle fleet at about 15 years this makes the hybrid vehicle more expensive to run and more damaging to the environment in terms of resources used, despite the fact that it is much more economical in fuel consumption. This fact alone makes it an elitist plaything and accounts for it's very poor resale value.

What the hybrid vehicle needs is an enabling technology that can extend that life of the hybrid's main battery. The Power Jockey is one such invention. It enables a much weaker battery to work with the hybrid vehicle drive system.

If we assume that the main battery needs to be at 70% of it's designed strength to function in the vehicle drive train and this position is reached after 7 - 10 years, the Power Jockey can lower this minimum requirement to say 50%. This could stretch the expected useful life of the battery to between 12 - 15 years.

If we add reconditioning and rebuilding of the main battery pack above the minimum capacity threshold we could conceivably extend the useful life of that same single main battery pack for the rest of the useful life of the vehicle. Perhaps 20 - 25 years.

Article in Wall Street Journal 24 September 2012 reports that already 26% of all Toyota's vehicle sales in Japan are Hybrids, while in the US it sold only 176,000 hybrids into the 1.6 million annual vehicle sold there. Toyota predicts that they will sell 1 million hybrids anually by 2015.


TOKYO—Toyota Motor Corp. 7203.TO +0.85% put its weight behind hybrids on Monday, disclosing plans to roll out 21 new or redesigned gasoline-electric powered vehicles by the end of 2015 and playing down the near-term outlook for other alternative-fuel technologies such as all-electric vehicles.
The Japanese auto maker predicted its sales of hybrid models world-wide will likely top 1 million this year and every year through 2015.
While the rollout and forecast signal Toyota's confidence in its hybrid strategy, the company acknowledges costs must still be cut further to increase profitability and spur sales.
"Profits from conventional [gas] powered cars are still higher, so we need to reduce hybrid costs more in order to promote their diffusion," Takeshi Uchiyamada, Toyota's vice chairman and R&D head, said at a news conference.
Hybrids are becoming more mainstream in Japan. Toyota's sales of the gasoline-electric vehicles last year reached 310,000, or 26% of its total sales. But they remain a niche in other key markets such as the U.S. Last year, Toyota sold 178,587 hybrid models in the U.S., just a fraction of the 1.64 million vehicles it sold there overall in 2011.
The Japanese auto maker has high hopes for its "plug-in" hybrid, which can be refueled either at the gas pump or by plugging in to a standard electrical outlet. Cumulative sales of its Prius PHV, which debuted earlier this year, reached 15,600 last month, including 8,400 in Japan, 6,100 in the U.S. and 1,100 in Europe.
At the same, time Toyota plans to sell just 100 models of its newest electric vehicle, a subcompact EV called "eQ." That contrasts with rival Nissan Motor Co.,7201.TO +0.78% which has bet big on EVs with its Leaf compact.
Mr. Uchiyamada said Toyota is moving ahead with plans to localize production in China of hybrid engines by 2015 and hopes to follow suit in the U.S., but said the auto maker has made no decision yet on that.
"We are looking into it, but we haven't reached a formal decision or made any specific plans yet," he said.
Earlier this year, the company announced plans to shift production of its Highlander SUV hybrid to a plant in Indiana, but the core engine components-such as motors, batteries and converters-will continue to be exported from Japan.
Beyond the main thrust into hybrids, Japan's No. 1 auto maker also laid out its strategy in other fields of environmental technology, such as all-electric and fuel cell-powered vehicles. Toyota is tiptoeing into EVs with its first sales this year, and it won't begin commercial sales of a fuel cell vehicle for at least three years.
Mr. Uchiyamada indicated that proprietary technology makes FCVs hold more promising than EVs. "Anybody can make EVs, but that is not the case for FCVs," he said. "So we see a lot more potential in FCVs."
Toyota will begin sales of a compact SUV with an electric engine made by Tesla Motors Inc. TSLA +0.88% this week in the U.S. market, where it hopes to sell 2,600 of the $49,800 RAV4 EVs over a three-year period. The company will also introduce its eQ to such clients as local governments in the U.S. and Japan in December and China sometime next year, but sales of the ¥3.6 million ($46,146) vehicle will be limited to 100 units.
The auto maker said it would launch a fuel cell-powered sedan "around 2015" in Japan, North America and Europe, and collaborate with subsidiary Hino Motors Ltd.HINOY -0.31% to debut a fuel cell bus in 2016. It projected sales of FCVs in the "tens of thousands" by the 2020s.
Separately, Panasonic Corp. 6752.TO +7.21% said Monday it will provide Toyota with lithium-ion batteries for the eQ. Panasonic has a track record with batteries used in eco-friendly vehicles, demand for which is growing amid environmental concerns and higher oil prices.
Panasonic has supplied lithium-ion batteries for Toyota's Prius Plug-in and Prius Alpha hybrids.
