Regardless of what we may think of Honda's current styling direction or the excitement level of its latest models, we have the utmost respect for the automaker's engineering talent. So, when Honda sets itself a goal to achieve "top-of-industry fuel efficiency in every vehicle class within three years", it catches our attention.

Honda's so-called Earth Dreams Technology will encompass everything from gasoline and diesel engines to transmissions (including a CVT that will supposedly be both fun to drive and highly fuel efficient) and, of course, hybrids and fully electric vehicles.

Acura will get knee-deep in the efficiency game as well, as parent company Honda is also promising a hybrid SH-AWD system that will feature two 20kW electric motors that will independently drive their own wheels along with a 30kW electric motor to assist the 3.5-liter V6 engine and seven-speed gearbox (more on this soon).

Of course, Honda will have some stiff competition in hitting top efficiency scores in every category, as both Hyundai and Ford have made similar overtures over the last few years. That said, all it takes is one look at the comprehensively outlined plan in the press release after the break to realize the seriousness with which Honda is making this pledge.

Honda Announces Revolutionary Next-generation "Earth Dreams Technology"

-New plan calls for top-of-industry fuel efficiency in every vehicle class within 3 years-

TOKYO, Japan, November 30, 2011 - Honda Motor Co., Ltd. today announced the outline for a revolutionary next-generation technology for automobiles called "Earth Dreams Technology."

"Earth Dreams Technology" is a next generation set of technological advancements which greatly enhance both driving performance and fuel efficiency at a high level, using as its base advanced environmental technologies to pursue the joy of driving unique to Honda. It is a series of measures in which efficiency of internal combustion components including engine, and transmission, as well as electric-powered motor technology, is further improved.

Through its implementation first in the mini-vehicle N BOX and gradually onto other vehicle models, Honda aims to achieve top-of-industry fuel efficiency for every category within three years, while simultaneously setting a timeline of 2020 to reduce by 30% CO2 emissions for all products sold worldwide, relative to emission figures for 2000.

Inspiration of the "Earth Dreams Technology" name:
"Earth Dreams Technology" is an expression for a set of technologies which takes into account both our need to protect the environment and our desire to provide a joy of driving.

Key features of "Earth Dreams Technology"

1. A gasoline engine which realizes top level driving performance and fuel efficiency.
2. A compact diesel engine which realizes the world's lightest body*1, top-of-class*1 acceleration performance and fuel efficiency.
3. CVT which combines at a high level the fun of driving and fuel efficiency.
4. A two-motor hybrid system which realizes top-of-industry efficiency*1.
5. A high-efficiency, high output electric SH-AWD hybrid system which combines superior driving and environmental performance.
6. A compact, high efficiency electric powertrain for EVs.
Summary of key features

1. Gasoline engine which achieves top-of-industry driving performance and fuel efficiency

By enhancing Honda's original VTEC (Variable Valve Timing and Lift Electronic Control System) technology to thoroughly improve thermal efficiency and minimize friction, a combination of high output and fuel efficiency was achieved. Further, a new engine series employing a new structure for higher expandability was developed.

By gradually renewing the engine starting with the mini-vehicle N BOX, Honda aims to utilize this technology to achieve top-of-industry output and fuel efficiency in every vehicle class within three years.

A wide range of engine classes including the 660cc, 1.3L, 1.5L, 1.8L, 2.0L, 2.4L, and 3.5L classes will feature the technology.

[ 660cc class engine ]
Employs DOHC and VTC (Variable Timing Control) to improve intake efficiency. Further, the compact combustion chamber realizes high thermal efficiency.

By shortening the bore pitch compared to the present engine models and reducing the thickness of the cylinder block and camshaft, engine weight is reduced by 15%*3 and fuel efficiency is improved by 10%*3.
[ 1.3 to 1.5L class engine ]

Employs VTC, direct injection technology and the Atkinson cycle using the DOHC, VTEC technologies as the base.

Extensive friction reduction measures are implemented.

[ 1.8 to 2.0L class engine ]
Employs direct injection technology and the Atkinson cycle using the DOHC, VTEC technologies as the base. Further, implementation of VTC and high-capacity EGR (Exhaust Gas Recirculation) to both the intake and exhaust ports realizes significantly reduced friction.

For the 2.0L class hybrid vehicle engines, use of an electric water pump eliminates the need for a belt in the auxiliary device and contributes to a reduction in friction. The VTC system allows fuel-efficient driving in various driving styles.

[ 2.4L class engine ]
Based on the DOHC and VTEC technologies, it employs VTC and direct injection technology and implements extensive friction reduction measures.
Standalone engine features 5%*3 improvements in fuel efficiency and output as well as a 10%*3 improvement in maximum torque compared to the previous engine.

[ 3.5L class engine ]
Employs new valve train mechanisms and direct injection technology in the SOHC, VTEC, VMC systems to improve by over 10%*3 of fuel efficiency and 5%*3 of output, relative to the present standalone engine model.

2. A compact diesel engine which realizes the world's lightest body*1, top-of-class*1 acceleration performance and fuel efficiency.

Through optimizing engine rigidity and combustion pressure, an aluminum open deck for the cylinder block was enabled in this top-of-industry lightweight*1 1.6L class diesel engine.

By downsizing from the present 2.2L engine and extensively reducing mechanical friction in each section, a friction level equivalent to present gasoline engine models was achieved.
Optimized thermal management system thanks to improvements in the cooling system reduces CO2 output by over 15%*3.

Employment of a compact, high-efficiency turbocharger and weight reduction in the reciprocating sliding section realizes a sporty and nimble ride.

3. CVT which combines at a high level the fun of driving and fuel efficiency.

Three CVT structures for mini, compact, and mid-size vehicle classes are newly developed to be adopted for a variety of engine models.

Reinforced belt is used to realize a structure for which a wide ratio range can be set.
Implementation of analysis technology over the contact behavior between the belt and pulley, and a high-precision hydraulic control system allows for continual optimization of hydraulic pressure to the pulley under a variety of driving conditions, contributing to improved fuel efficiency.

Use of an electronic oil pump to realize an idle stop system with high response contributes significantly to improved usability and fuel efficiency.

"G-Design Shift", a new coordinated control system for shift transmission, throttle, and hydraulic control responds quickly to driver demands and realizes an exhilarating, sporty drive with superior acceleration.

In the mini-vehicle class, a control mechanism and innovations in axle placement to reduce the engine size lengthwise, while a reduction in parts by simplifying the transmission casing structure helps realize a lightweight and compact body.

For the compact and mid-size classes, in addition to the reductions in size and weight, transmission efficiency was greatly improved by expanding the ratio range to achieve fuel efficiency improvements of 5%*3 and 10%*3 compared to the conventional CVT and comparable 5ATs, respectively.

4. A two-motor hybrid system which realizes top-of-industry efficiency*1.

A two-motor hybrid system featuring top-of-industry efficiency*1 enhancing driving performance and reduced CO2 emissions has been newly developed.

Special lithium-ion battery and charger is employed to enable mounting on plug-in hybrid vehicles.

Mid-sized vehicles equipped with this system are scheduled to begin production, starting with the plug-in hybrid model in 2012 and the hybrid model in 2013.

Three driving modes allowing for top-of-industry efficiency*1 for various driving environments were developed; an "EV driving mode" for urban environments, a "hybrid driving mode" using electricity generated by the motor, and a "engine-connected driving mode" where the engine and tires are mechanically connected during high-speed cruising.

Combination with a high-output 120kW motor allows for superior environmental performance and driving enjoyment.

5. A high-efficiency, high output electric SH-AWD hybrid system which combines superior driving and environmental performance.

A new hybrid system, electric SH-AWD, was developed for large-sized vehicles. By combining a 3.5L, V6 engine with this hybrid system, acceleration equivalent to V8 engines, as well as fuel efficiency equal or superior to in-line 4-cylinder engines were realized.

An electric 4WD system with independent 20kW+ motors on both sides for the rear wheels combines a 7-speed dual clutch transmission system with a built-in 30kW+ high-efficiency motor with the engine.

By mounting a high-performance lithium-ion battery and optimally controlling the front and rear motors, a new hybrid system with high fuel efficiency and output was realized.

By mounting two independent motors in the rear and employing a newly developed bilateral torque adjustable control system, incredibly tight cornering just like driving "on-the-rail" is realized. With this mechanism, Honda strives to provide a stable ride for various driving environments.

6. A compact, high efficiency electric powertrain for EVs.

Thanks to the high efficiency coaxial motor, low-friction gearbox and electric servo brake system, the system realizes the highest electrical consumption capability in the world*1, meeting the required AC consumption rate of 29kWh/100mile(116MPGe) as set forth by the United States.

A traveling distance of 123 miles*2(LA-4mode: unadjusted) or 210km*2(JC08 mode) was achieved thanks to the mounting of a high capacity lithium-ion battery.
When using the 240V U.S. electric source, a full charge takes less than 3 hours. (From the time a low-charge signal is lit till full charge)

By offering three driving modes (SPORT, NORMAL, ECON), the driver can freely select from a number of options to meet the needs of various driving styles such as power-saving or sporty drive.

      That sounds like a challenge and consumers will benefit if fuel efficiency becomes one of the things that car companies really battle one another for trying to get top ratings.

      airchompers....you're getting caught up in the wave of media hype. Yes, Hyundai's get better EPA fuel economy numbers, but look at the real world results (fueleconomy.gov) or any of the major auto publication and you'll quickly notice they don't deliver the advertised results. Honda's typically outperform EPA results while Hyundai's underperform. As both a Hyundai and Honda owner, I can say Hyundai's made a lot of progress, but they're still no Honda. ALso look at the recent comparo's where the darling Sonata finishes last (recent CD and MotorTrend articles). And which family sedan made C&D's 10 best list for 2011. Wasn't the Sonata that made it the year prior, but the Accord which has been on 26 times now. Honda's not what they used to be, but they're still ahead of the competition in many ways.

        "Honda's typically outperform EPA results while Hyundai's underperform." Not quite according to the EPA's real-world reports. Accent readily outdoes Fit. Sonata I-4 beats Accord. CR-V and Tucson are only .3 apart and the sample size for each is so small as to make that meaningless. There's no data for a Veracruz vs. Pilot comparison and Santa Fe's too much smaller to make a comparison with Pilot fair, though it does do better. That pretty much leaves only Elantra as established as doing worse than its Honda competition. It should be noted much of that seems to be predicated on gripless tires. When CR tested the Civic with better tires, the mileage difference shrank to just 5 gallons a year and while dry braking then came to within a foot of Elantra rather than within a foot of F-150 with the standard tires, wet braking still was only three feet shorter than F-150. Hardly a basis to say typically.

      Honda is dead. Dead and gone. Here's the situation. There's no integras, no preludes. Hyundai (which designed its very first engine in 1991) is making normally aspirated engines that getter better milage, make more power, and are smoother than Honda engines. The most exciting Honda motorcycle is a 250cc motorcycle that is fun precisely because it isn't fast. Honda forgot what made it great: a tenacious appetite to do the impossible. Soichiro Honda declared Honda would win the Isle of Man within 5 years before Honda had even made a reliable >50cc motorcycle. Honda introduced variable valve timing on economy cars the same time ultra luxury European brands were introducing it on the top of the line cars. Honda built the NSX which wasn't the fastest car ever, but it might be the most important supercar ever made because it changed people's expectations of supercars so much. With the NSX, honda made a race car for the street that could be driven every day. And Honda can't turn it around for at least 5 years. We don't know how Honda is presently. But from the Civic and CRV we know that Honda of 3 years ago (who designed these cars) didn't get it. They were resting on laurels and weren't pushing the state of the art. It'll be very interesting to see if the next Accord is any good. Because if it's anything less than a knockout, then we'll know that Honda still doesn't get it.

      2012 and 2013 will put Honda at the top in every category....all product gets a little stale after 4-6 years, Honda has billions on their balance sheet and spend the highest % on R&D of any mfg. You can't count them out....Hyundai can have their 15 min of fame but that's about to roost in 2012 and 2013. Honda will be back!

          I have an 89 Prelude, and it's 100% stock except for some stickier tires and a catback exhaust. On a road course I handily beat a VW R32, a Mustang SVT Cobra (2000ish), and bunch of other cars easily worth 10x what my prelude is. Don't be so cocky.
