    1.Employs VTC, direct injection technology and the Atkinson cycle using the DOHC, VTEC technologies as the base.
    2.Extensive friction reduction measures are implemented.

    [1.8 to 2.0L class engine]
    1.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.
    2.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]
    1.Based on the DOHC and VTEC technologies, it employs VTC and direct injection technology and implements extensive friction reduction measures.
    2.Standalone engine features 5%*2 improvements in fuel efficiency and output as well as a 10%*2 improvement in maximum torque compared to the previous engine.

    [3.5L class engine]
    1.Employs new valve train mechanisms and direct injection technology in the SOHC, VTEC, VMC systems to improve by over 10%*2 of fuel efficiency and 5%*2 of output, relative to the present standalone engine model.

    1. A compact diesel engine which realizes the world’s lightest body*1, top-of-class*1 acceleration performance and fuel efficiency.
    2.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.
    3.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.
    4.Optimized thermal management system thanks to improvements in the cooling system reduces CO2 output by over 15%*2.
    5.Employment of a compact, high-efficiency turbocharger and weight reduction in the reciprocating sliding section realizes a sporty and nimble ride.

    CVT which combines at a high level the fun of driving and fuel efficiency.
    1.Three CVT structures for mini, compact, and mid-size vehicle classes are newly developed to be adopted for a variety of engine models.
    2.Reinforced belt is used to realize a structure for which a wide ratio range can be set.
    3.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.
    4.Use of an electronic oil pump to realize an idle stop system with high response contributes significantly to improved usability and fuel efficiency.
    5.“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.
    6.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.
    7.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%*2 and 10%*2 compared to the conventional CVT and comparable 5ATs, respectively.

    A two-motor hybrid system which realizes top-of-industry efficiency*1.
    1.A two-motor hybrid system featuring top-of-industry efficiency*1 enhancing driving performance and reduced CO2 emissions has been newly developed.
    2.Special lithium-ion battery and charger is employed to enable mounting on plug-in hybrid vehicles.
    3.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.
    4.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.
    5.Combination with a high-output 120kW motor allows for superior environmental performance and driving enjoyment.

    A high-efficiency, high output electric SH-AWD hybrid system which combines superior driving and environmental performance.
    1.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.
    2.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.
    3.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.
    4.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.

    A compact, high efficiency electric powertrain for EVs.
    1. 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.
    2.A traveling distance of 123 miles*3 (LA-4mode: unadjusted) or 210km*3 (JC08 mode) was achieved thanks to the mounting of a high capacity lithium-ion battery.
    3.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)
    4.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.

    What a horrible name... But hope it goes well. If not, in a few years I might have to jump ship and get a VW or something... The current Honda line up has nothing exciting anymore...

    Direct Injection.... Small Turbo engines... DSG transmission.... Sounds like a VW press release 5 years ago. Not wsaying is a bad thing (any development is better than the current Honda lineup), but Honda is like an entire product cycle behind VW, and half a product cycle behind Hyundai/Kia.

    HAving said that, Skyactiv still makes this "earth dream" look medieval.

    And Honda's going Atkin's cycle combustion.... atkin's cycle us known to lower power-to-displacement ratios... this is going to be interesting..... because to compensate for the lower power-to-displacement... they gonna need electric motors to drive the car if you stump on the gas (ala Toyota Prius)

    technology

    although the world's car technology is dramastically improving, but i still think putting a turbo in a honda engine and giving up manual gearbox is not what honda should do. Should power up the VTEC technology instead of a turbo lol

    Thats exactly my concerns, this whole raft of new-tech (NEW to honda) means... well quality WILL drop, it took VW a generation to get it all right (and they still arent perfect).....
