A greener Honda: car company to recycle hybrid batteries for rare earths

On Wednesday, Honda Moto Co. announced that as part of an increased effort to go green and be environmentally friendly, the car manufacturer will begin recycling rare earth materials this year from the batteries used in hybrid cars. As a whole, Japan is heavily dependent on imports to get its rare earth elements, especially from China. While the materials are invaluable for the manufacturing of high-tech consumer electronics, ongoing tensions with China pose a threat to Japan’s supply.


Honda claims that they will be the first in the auto industry to start rare earth recycling, with the hopes of a September or October launch. Takanobu Ito, Honda’s president, commented that the future of Japan’s energy policy has become uncertain in the wake of the Fukushima nuclear disaster, and there is no better time than now to make a push towards the use of renewable energy sources. Ito also said that Honda is making efforts to decrease pollution and its contribution to global warming, and one day hopes to make cars that combine the company’s fuel-cell technology with solar power, creating a car that runs on energy from nature only.

The Honda president pointed to founder Soichiro Honda’s focus on the environment, and how he would tell workers that everyone in the auto industry is responsible for trying to reduce emissions. Prior to Honda’s entrance into the U.S. market, the company had set a goal for building a fuel-efficient gasoline engine, in order to pass the country’s strict regulations against pollution. Honda created its legendary CVCC engine in the 1970s, and was the world’s first auto maker to clear the standard. Shortly after, regulations against pollution were also adopted in Japan.

Honda Brio diesel caught testing yet again

This is not for the North American market....

Honda unveiled a new mass market 1.6-litre diesel i-DTEC EarthDreams engine at the 2012 Geneva Motor Show, and it was very clear that diesel powered Honda cars won’t take too long to reach Indian market. Also, Honda had confirmed that they will launch the Brio diesel by Diwali this year and since then lot of test lues have been spotted around their plant near Delhi, not looking very different but with distinctive diesel clatter.

This time our friends at Team-BHP caught the test mule, who report about the eminent diesel noise from the car. They also suggest that this tiny diesel is also sprightly, as the driver tried to get away when followed. So, the Brio diesel will now get even smaller engine based of the 1.6-litre EarthDream, just that exact details are yet to be know. Honda will need a engine smaller than 1.5-litre so that they will be eligible for the subsidy. Plus the engine will need to have sufficient power, as it will also power the Jazz later, just like the 1.2-litre petrol doing the duty.]

Honda is entering diesel market in India with their smallest car and is clearing looking at the number game. The rumours suggest that the City will be the next Honda model to get a diesel – which might get bigger displacement mill, probably same as the one unveiled at Geneva. The last among mass production models will be the Jazz diesel.

The Honda City is the highest selling petrol sedan in its segment; even the Brio san diesel is doing quite well in the entry-level hatchback segment. Honda is known for refinement and reliability in India and is one of the most respected brands in mass market. Addition of diesel to their range will certainly increase their numbers and is going to be a threat to all their competitors.

Honda: 2013 Accord one of 'most feature-rich vehicles we've ever made'

Honda watchers counting on a restyled 2013 Accord to reignite the Japanese automaker's sales spark in the United States may be disappointed by the first spy images emerging of the sedan.

Photographs captured this week show the mid-sized sedan with only evolutionary changes from its previous design. In a segment that will be filled with several bold redesigns by next spring -- the Toyota Camry, Volkswagen Passat, Nissan Altima, Chevrolet Malibu, Ford Fusion and Mazda6 -- the Accord could find itself fighting for a seat at the head of the table.

In engineering the new Accord, Honda executives say they learned their lesson when they removed too much content on the redesigned 2012 Civic.

"You're going to find that Accord is a very well-balanced product that is the best overall product in everything, whether we're talking about interior packaging, content of the vehicle, the fuel economy of the vehicle," Erik Berkman, head of research and development for Honda Americas, told Bloomberg News in a recent interview.

It "will be one of the most feature-rich vehicles we've ever made," Berkman added, without elaborating.
The new Accord is expected to go on sale early this fall.

A merely evolutionary design change to the Accord could spell trouble when the competition is making huge jumps in styling, especially the Ford Fusion with its Aston Martin-like lines.

Hyundai and Kia have also gained ground in the U.S. market with radically designed mid-sized sedans.
The 2013 Accord is the last of four core models Honda will introduce over a 24-month period. An all-new Odyssey minivan went on sale in late 2010, followed by the new Civic compact last spring and the revamped CR-V in late 2011.

The four models accounted for nearly 80 percent of the Honda brand's U.S. sales last year.

Accord sales last year fell to 235,625 units, representing a 17 percent decline, although a big chunk of the decline was tied to earthquake-related parts shortages.

But it's still a long way from previous years when the Accord produced annual sales of nearly 400,000 units.
Last year, the rival Nissan Altima became the second-best selling car in the United States after the Toyota Camry.

So far in 2012, the Accord is the fourth best-selling car in America, after the Camry, Altima and Honda Civic.

The revamped Accord will feature Honda's new "Earth Dreams" family of engines and related technology, including continuously variable transmissions, the automaker's first such powertrain change in a decade.
Honda previously used CVTs only on small cars made in Japan.

Starting with the 2013 Accord, the new transmission, with an infinite number of gear ratios, will replace the current five-speed automatic to aid fuel-economy and performance.

The CVT will be the only automatic offered in the Accord four-cylinder, but the V-6 will come with a traditional geared transmission.

The engine line, with displacement ranges from 660 cubic centimeters to 3.5 liters, is being added to every new Honda model starting with the Accord.

Honda Earth Dreams Technology – aiming for best in class fuel consumption in every segment, with fun to match

May 1, 2012 at 1:34 pm By Danny Tan Filed Under 2011 Tokyo Motor Show, Cars, Feature Stories, HondaAlong with concepts like the EV-STER and Micro Commuter, Honda officially revealed its banner for next generation technology called Earth Dreams Technology at the 2011 Tokyo Motor Show. The company, and president/CEO Takanobu Ito, promises both to care for the environment and provide joy of driving under EDT. From what we’ve heard and experienced, it sure smells as sweet as Eau De Toilette!

There are few main weapons in the Earth Dreams Technology arsenal, comprising new petrol and diesel engines, a CVT gearbox, a fresh “two-motor” hybrid system, electric SH-AWD for efficient performance and of course, a compact electric powertrain for EVs.

With these, Honda is aiming high. No, forget high, let’s make it THE top. With Earth Dreams Technology, Honda is looking at being the fuel efficiency leader in every vehicle class within three years – how’s that for a mission? Alongside this FC target is a plan to reduce CO2 emissions by 30% for all products sold worldwide by 2020, relative to emission figures from year 2000.
Continue reading after the jump.


Let’s start with petrol engines and what Honda is so famous for, VTEC. Honda has enhanced its much vaunted variable valve timing and lift control system for better thermal efficiency and reduced friction. This will benefit both ends of the scale – fuel efficiency and higher output.
This “new VTEC” will be homed in a new engine series which has a new structure and higher expandability. The new range will include players in every engine class – from the JDM minicar standard of 660 cc to a 3.5 V6 that Americans require. Four cylinder units displacing 1.3, 1.5, 1.8, 2.0 and 2.4 litres will sit in the middle.

Another major shift is the use of the Atkinson cycle, till now only seen in Toyota’s hybrid models. The Atkinson cycle provides high efficiency at the expense of power density. It’s also not the strongest at low engine speeds, so this is where Honda’s twin cam VTEC know how comes into play, normalising the situation. Honda plans to use the Atkinson cycle from 1.3 to 2.0 litre sizes; no change for engines outside this range.
That’s not all, as 1.3L engines and above will all receive direct injection. The 1.8 and 2.0 engines, likely to power Honda’s future C-segment cars like the Civic and CR-V, will also get high capacity EGR (Exhaust Gas Recirculation). If used with motor assist in a hybrid, the 2.0L engine will come with an electric water pump, eliminating the need for a belt in the auxiliary drive and reducing friction.

Honda gave us a sample of this next gen engine, which in 2.4L guise features direct injection, DOHC VTEC, VTC, high tumble port, double arm chain system plus “extensive friction reduction measures” and Idle Stop. With all these, Honda claims 5% improved economy and 5% better output, along with 10% more torque – the latter is also more accessible thanks to a friendlier torque curve.
The improvements over today’s K24A is noticeable. Housed in an Accord Euro and paired to a CVT, the new engine has sharp response on take off, opposed to today’s “comes alive at high rpms” character. Can’t quite remember the top end feel though, no thanks to the CVT. But one thing’s for sure – it performs with vigour that’s not very common in the class. Figures? Over 181 hp and over 240 Nm is what they’re ready to reveal at this point.

Japanese carmakers are always critisised for their lack of diesel engine development, so when we were told that there’s a new oil burner for sampling, we were naturally excited.
Honda will be replacing the 2.2L diesel it uses in Europe now for a thoroughly modern downsized unit – a 1.6L that’s aiming for best in class acceleration and fuel efficiency. I can see people at VW and PSA scratching their heads in disbelieve, but Honda is saying it with a straight face.

Firstly, this new 1.6L diesel is compact and has the world’s lightest body, according to its maker. Optimising engine rigidity and combustion pressure allowed them to use an aluminium open deck for the cylinder block, saving previous grams. Reducing mechanical friction was also a main objective, and the result is on par with current Honda petrol engines. There’s also a new compact and more efficient turbocharger.
This engine will make roughly 120 hp and 300 Nm of torque, but boy, it feels much better than that. Also demo-ed in an Accord Euro, but with a six-speed manual gearbox, you hear no diesel clatter in the car, and there’s no turbo lag. What’s nice is the way it revs so cleanly without any lack of breath or added vibration at high rpms.

“Like a petrol engine” is often used to describe nice diesels, but this is even smoother revving than many petrols. And since manual gearbox feel is something of a Honda trade secret, the package is top notch. In Malaysia, we can start writing a song dedicated to Honda titled “If Only”.
Honda is on a mission to inject sportiness and fun driving back into the mix, after focusing solely on green for some time, and the new SH-AWD (Super Handling All Wheel Drive) represents this efficient performance mix well. Developed for future large vehicles, the new SH-AWD is essentially a “hybridised” version of the physics defying tech. Presently, SH-AWD is a mechanical torque vectoring rear axle that can be found in high end models like the Legend and US market Acuras.

The electric SH-AWD was housed in an Accord body for sampling. Up front is the new direct-injected 3.5-litre V6 with 310 hp and 360 Nm. It is assisted by a 40 hp, 130 Nm electric motor and mated to a self-developed seven-speed dual-clutch gearbox. At the back, each rear wheel is connected to a 27 hp, 70 Nm electric motor. The result is four-wheel drive without a link between front and rear axles.
Each rear motor is independently controlled, and can deliver either positive or negative torque. Instead of just directing torque to the outside wheel for more traction, SH-AWD can simultaneously generate power from the inside wheel, neutralising power use.

It’s sort of like taking from one hand and putting it into the other, in every corner. The front wheels does the usual regenerating thing. It’s all extremely efficient, and Honda says that this combo can deliver V8 go with four-cylinder fuel economy. And of course, there’s the physics defying traction. View this short video to better grasp the concept.
We tried the SH-AWD Accord mule on a very short loop of the Motegi road course, and yours truly came away very impressed. Here’s a big heavy car that can corner like few other. There’s so much more traction in the corners when the regular FWD Accord would have already washed wide, leading me to carry higher than expected speeds in the corners.
It was a super brief stint, but the slalom run gave the Accord, which is already the entertainer of the class, a chance to show off its nimble feet. It danced, not plowed, around the cones, and the car’s tail played along. Ok, it wasn’t drifting, but it was obvious that it wasn’t just front end grip dragging the car around. The only negative factor is major body roll, but that’s not part of what’s being tested here. Highly promising.
There was also a seven-speed dual-clutch gearbox in the evaluation car. It wasn’t conspicuous, which is a good thing to report for a DSG type ‘box.

Honda develops new CVT, available with Step WGN

The vehicle below will not make it's way to North America, however it's interesting to see what they are doing with the CVT....
Whether you are a fan or not, the CVT gearbox is here to stay. Point in case is the new CVT from Honda, which is part of their Earth Dreams Technology, specially developed for mid-sized Honda vehicles.

This new CVT features newly developed high-efficiency electric oil pump, high-strength belt and exclusive CVT oil raise transmission efficiency, which enhances fuel economy. It also features a wide ratio that gives more torque in the lower rpm range that translates to quick acceleration from standstill. In addition, the new CVT is equipped with the G-Design Shift that controls the gearing, throttle and hydraulic control to make the system respond quicker to driver input.

The take back from this new CVT is that it offers five percent better fuel economy than the conventional CVT, and 10 percent better than a traditional 5-speed automatic. The new CVT will not reach us yet. It is still new in Japan and will be first shoehorned into the Step WGN and Step WGN Spada.

Honda's Earth Dreams Tech Making Fuel Efficiency a Reality

By Stephan Edlestein

New technology will give Honda what it needs to compete with its rivals, and will power everything from the Accord sedan to the NSX supercar.

At the Geneva Motor Show, Honda revealed details about its new, more fuel-efficient powertrains. These new engines, collectively known as Earth Dreams, will power most Honda vehicles in the near future, including the next NSX sports car. “We aim to be number one in fuel economy in each sector within three years,” said Honda’s European CEO, Manabu Nishimae. “Through Earth Dreams Technology, Honda will continue to minimize our environmental footprint.”

Like Ford’s EcoBoost and Mazda’s Skyactiv, Earth Dreams is a brand name for engines upgraded with new technology. Honda will add VTC (Variable Timing Control), direct injection, and will build conventional gasoline-powered cars with Atkinson-cycle engines, even though that setup is usually found in hybrids. Adding direct injection, which shoots a precise amount of fuel into the combustion chamber, is an important step if Honda wants to compete with Ford and Mazda, let alone Hyundai and Kia.

Honda will also improve its diesel range under the Earth Dreams banner, reducing its engines’ displacement and weight to cut emissions and improve fuel economy. Honda will also replace its mild-hybrid IMA (Integrated Motor Assist), with a new system that features lithium-ion batteries and plug-in capabilities. Because IMA only allows drivers to use electric power for brief periods, Honda’s hybrids have never been able to compete with the Toyota Prius on fuel economy. The new system should remedy that.

To put its engines’ green power to the road, Honda will rely more on Continuously Variable Transmissions (CVT). Enthusiasts may not like the CVT’s eerily linear power delivery, but some kind of transmission upgrade was necessary. Honda offers a five-speed transmissions in the Accord, while most of the competition offers six.

The U.S. Will get its first Earth Dreams engine, a 2.4-liter inline-four, in the 2013 Accord. Europe will get a 1.6-liter diesel in the Civic. Honda says the diesel is the lightest of its kind and produces an extremely low 95 grams of CO2 per kilometer.

Earth Dreams technology will also be incorporated into the new Honda/Acura NSX’s V6. That engine, combined with the NSX’s three electric motors, will provide “supercar acceleration and outstanding efficiency,” Honda says. The NSX will go on sale in Europe by 2015, badged as a Honda. There was no update on the car’s U.S. launch.

“The NSX is the ultimate top-line sports model,” Nishimae said, “could we develop a smaller one?” He noted the EV-STER, an electric roadster concept making its European debut at Geneva, as an example of how green powertrain technology could be applied to a small, fun-to-drive package. Such a car would make a great replacement for the S2000.

With Earth Dreams, Honda is making a concerted effort to upgrade its basic engines and transmissions, something it will need to do to remain competitive. By starting from the bottom, Honda hopes to see improvements across its entire lineup, everything from sedans to sports cars.

The 2012 Honda Civic will be the first car to get the Earth Dreams 1.6 Liter i-DTEC turbo diesel engine

Again, not for us in North America....

Honda has a top priority Earth Dreams project that it has had running at its Japan research and development center for a while now. The project we’re talking about involves the development of a range of new generation turbodiesel engines that the Japanese automaker will use in its future products, as it seeks to improve market share in times when diesel engines cars are become more and more preferred by car buyers across the world for their high fuel economy and low CO2 emissions.

The first engine that Honda has spawned out of its Earth Dreams turbodiesel engine project will power the upcoming 2012 Honda Civic Sedan. This turbo diesel engine displaces 1.6 liters and comes in an inline four cylinder layout. The 1.6 Liter i-DTEC engine pumps out a peak power of 120 Bhp generated at a low 4,000 rpm while the peak torque of 300 Nm generated at 2,000 rpm talks the loudest, with it being a class leading figure considering the i-DTEC engine’s displacement.

This apart, the other big story surrounding the 1.6 Liter i-DTEC turbo diesel engine is the low carbon dioxide emission level, which at 95 grams/Km is outstanding. Also, the Honda i-DTEC engine is said to be the world’s lightest aluminium open deck 1.6-liter diesel engine due to the use of strong yet light weight materials in its construction. The 1.6 Liter i-DTEC engine will be manufactured at Honda’s UK plant at the end of 2012.

In due course of time, expect this very engine to arrive into India as Honda desperately needs a diesel engine in its portfolio to survive and thrive in the Indian car market, which has migrated to the more fuel efficient diesel engined cars due to the prices of the non-subsidized petrol rising even as diesel remains the overwhelmingly cheaper alternative due to the Indian government subsidizing it.

Honda President Commits to “Distinctive” and “Sporty” Vehicles

After having taken quite a beating with reviews of the new Civic, Honda has been on the offensive, promising updates while announcing its new “Earth Dreams Technology” plan to reestablish itself as a fuel economy leader. With the debut of the EV-STER electric sports car concept and confirmation that a new NSX is on the horizon, company president Takanobu Ito is now going a step further, while explaining the faults of the past.

In an interview with the The Nikkei, he explains Honda’s old product planning method. “We divided the world into six regions, and Honda’s regional operations were each responsible for their respective regions. Whenever we planned a product for the global market, our thinking was that we needed to listen to each regional supervisor.”

The result, says Ito, was a lowest-common-denominator approach to building a car, watering down all the characteristics of a vehicle to the greatest mass-market appeal. The problem admits Ito is that, “When you harmonize all the different opinions, you end up with a safe, boring car.”
Under the old method of doing business, the vehicle development team was essentially taking the designed-by-committee idea and building a car around it.

Ito says that since he took over in April of last year, changed the system. “I had three corporate officers each supervise luxury, midsize and small vehicles,” he said. “Putting more authority in their hands, I asked them to create more competitive autos and to speed up coordination with product planning and regional operations. I set up a structure that would allow them to take the lead in realizing the wishes of the development team. The fruits of these moves will begin to appear in the market next fiscal year.”

Exactly what those fruits are, says Ito, will be cars that are environmentally friendly and safe, but also ones that are “highly distinctive”. Honda, after all, has a long history of unique vehicles from the NSX, S2000, CRX and del Sol. But perhaps most importantly, he says, “This strategy will be represented by our effort to make vehicles more sporty.”

The first true example of this plan will be evident when Honda unveils the next-generation NSX at the Detroit Auto Show next week.

Honda Commited to fuel economy

by John Leblanc

MOTEGI, JAPAN — Honda, like most of its rival Japanese automakers, has been taking it on the chin of late when it comes to its perceived lack of engineering and product innovation.

With up-to-date features like direct-injected and turbocharged engines and multi-gear or continuously variable (CVT) transmissions more than likely found in rivals from Germany, America or Korea, many customers perceive that Japanese automakers have lost their engineering mojo, or have forgotten how to innovate, after years of being at the top of the sales charts.

The day before it rolled out three concepts at the Tokyo Motor Show that showcased what we may be driving in 2020, Honda unveiled a slew of state-of-the-art technologies at the Twin Ring Motegi Super Speedway that will appear in new cars as early as next year.

The message was clear to the attending media: Honda is back in the business of innovation, and aims to be a leader in fuel economy.

“The first task, when I started as president, was to get ahead of (the competition), particularly in the area of hybrid batteries and fuel cells,” said Honda Motor CEO Takanobu Ito, who’s been with the company since 1978 and took over the top job in 2009.

Ito also said that Honda wants to have "the No. 1 fuel economy in each (vehicle) category within the next three years."

To get there, and under the marketing banner of “Earth Dreams,” the automaker is rolling out a family of new hybrid and gas engines, CVTs, and all-wheel-drive systems, all slated to appear in new models as early as next year.

On the hybrid front, Honda’s new 2013 midsize Accord (due late next year) will receive a plug-in electric hybrid version of the company’s new “two-mode” gas-electric system.

When mated with a four-cylinder engine, Honda is claiming equal power to the existing Toyota Camry Hybrid (200 hp), but better fuel economy than the Toyota’s 4.7L/100 km combined rating.

Technically, Honda’s new two-mode hybrid uses a twin-cam profile. However, instead of using the automaker’s traditional VTEC (Variable Valve Timing and Lift Electronic Control) profile for more power, the hybrid version shifts between an Atkinson cycle (for leaner fuel burning), and the traditional Otto cycle (for more power , depending on the torque load on the engine).

Honda says the system can also be combined with a V6, driven in electric-only mode for up 24 km, electric-and-gas for accelerating, or gas-only for highway cruising.

Once a leader, Honda is catching up to the competition by adding direct-injection and double overhead cams to its mainstream gas engines.

Dubbed “i-VTEC, the new engines promise more power and “at least” a 10 per cent fuel economy advantage over the outgoing powerplants.

For example, the 2013 Accord will get a new i-VTEC 2.4-litre four-cylinder with 181 hp and 177 lb.-ft. of torque (all preliminary ratings), up 4 hp and 16 lb.-ft., respectively, from the existing Accord four.

As well, a new 1.8L i-VTEC, with 148 hp and 133 lb.-ft. (gains of 8 hp and 5 lb.-ft.) may end up in the refreshed 2013 compact Civic, while a new 1.5 i-VTEC with 127 hp and 111 lb.-ft. (10 hp and 5 lb.-ft.) could find a home in the subcompact Fit.

Shying away from CVTs in the past, Honda is now working on three new units — one for mid-sized cars such as the Accord, and two for smaller vehicles such as the Civic and Fit — that will become the base automatic transmissions for all four-cylinder engines.

While competitor CVTs have a "rubber band" feeling similar to a slipping clutch under acceleration, the Honda system I drove at Motegi, in an Acura TSX test mule with the new i-VTEC 2.4, felt more like a traditional torque converter automatic, free of the high-pitch whine usually associated with CVTs.

Honda says the new i-VTEC’s engine control software has been remapped so there is less “hunting” for revs during hard acceleration.

Honda’s premium Acura brand will also see immediate benefits from the automaker’s recommitment to new tech.

“We are not satisfied with the brand’s current positioning. We want to make it more unique and sporty. We want to make it into a ‘high-end’ brand,” said Ito.

The midsize Acura TL sports sedan will receive a new 3.5-litre i-VTEC V6, now with 310 hp and 265 lb.-ft. of torque — 30 more horsepower and 11 more lb.-ft. than the current car’s base six.

More interestingly, Honda also had on hand an Accord engineering test mule that encompassed many of the new technologies that may end up in the oft-rumoured Acura NSX replacement.
Called Electric Super Handling-All-Wheel-Drive, and in the prototype we drove, a new i-VTEC 3.5-litre V6 was mated to an also-new seven-speed dual-clutch auto box with an integrated hybrid-electric motor that also uses the energy from regenerative braking to provide the power boost. All four wheels are independently powered, depending on the car’s cornering and traction needs.

When pressed, Honda engineers told us the hybrid powertrain was rated “well above 300 hp.”
But by the way the car shot forward from rest, my seat-of-the-pants were telling me that that number could be closer to 400 hp.

Speculation in the Motegi paddock was that a new concept car, in the spirit of the Acura NSX super car, would encompass all of the Accord Electric SH-AWD test mule’s new hardware, and is set to appear at next January’s Detroit auto show.

When asked about such a car, Ito replied, “I don’t know. Stay tuned!”
