Honda has outlined its next-generation technology for automobiles at the Tokyo Motor Show. "Earth Dreams Technology" is a broad revamp of engine and transmission technologies with which the company aims to achieve ambitious, industry-leading fuel efficiencies 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.

Earth Dreams Technology incorporates the following key elements:

  • Revised gasoline engines: Honda's has built on its original VTEC (Variable Valve Timing and Lift Electronic Control System) and developed a new structure for higher expandability to improve output and fuel efficiency. The new tech will appear in a wide range of engine classes including the 660cc, 1.3L, 1.5L, 1.8L, 2.0L, 2.4L, and 3.5L.
  • World's Lightest Diesel Block: Honda says that by optimizing engine rigidity and combustion pressure, an aluminum block has produced the world's lightest 1.6L class diesel engine.
  • New CVTs: Honda will introduce a range of hydraulically controlled CVT-based transmissions for mini, compact, and mid-size vehicle classes, as well as "G-Design Shift", which co-ordinates shift transmission, throttle, and hydraulic control for a more sporty drive.
  • Two-motor hybrid system: A new two-motor hybrid system featuring a special lithium-ion battery and charger for plug-in hybrid vehicles has been developed with three driving modes, catering for urban through to high speed cruising.
  • High output electric SH-AWD hybrid system: A new hybrid for large-sized vehicles combining a 3.5L, V6 engine that Honda claims provides acceleration equivalent to V8 engines, as well as fuel efficiency equal or superior to in-line 4-cylinder engines.
  • Electric 4WD system: This incorporates independent 20kW+ motors on both sides for the rear wheels plus a 7-speed dual clutch transmission system with a built-in 30kW+ high-efficiency motor with the engine.
  • Compact, high efficiency powertrain for EVs: Thanks to a high efficiency coaxial motor, low-friction gearbox and electric servo brake system, this system is claimed to meet the required AC consumption rate of 29kWh/100mile(116MPGe) as set forth by the United States, providing a range of 210km (JC08 mode) from its lithium-ion battery. When using the 240V U.S. electric source, a full charge takes less than 3 hours according to Honda (from the time a low-charge signal is lit till full charge) and there are three driving modes (SPORT, NORMAL, ECON) with which the driver can dial up whatever performance takes his or her fancy.

Fuel efficiency is nice but but measuring CO2 emissions is patently ridiculous.


Bring it on, Love the sport, normal, econ settings - can\'t imagine I would ever use NORMAL LOL


YES-best news in a long time-go HONDA! I want them. Now make a large camper van style vehicle combining some of these ideas-the new CVT-the lightweight diesel etc. If you make them we WIll buy them. Great.
