Hybrid Powertrain Technology

SPORT HYBRID

Honda offers the SPORT HYBRID, which is not only top-class in fuel economy, but also a new level of fun in driving never before seen in hybrids.

A new generation of lightweight and compact vehicles
One-motor SPORT HYBRID

i-DCD

A drive unit that achieves a 30% or greater increase in efficiency over traditional one-motor hybrid systems by combining a newly-developed in-line four-cylinder 1.5L class engine, a seven-speed dual clutch transmission with built-in high-output motor, and a lithium ion battery.


Two-motor SPORT HYBRID with the best efficiency in the world

i-MMD

Achieving the best efficiency in the world*1 by combining a newly-developed engine dedicated for hybrid vehicles, an electric CVT coupled with two built-in motors and a lock-up clutch, and a lithium ion battery, and also by optimally switching between three drive modes according to the driving situation.

SH-AWD

Honda’s unique system achieves both fuel economy and superior driving performance at a whole new level by combining a new V6 direct-injection engine and a newly-developed DCT system with a built-in motor, while enabling free control torque distribution to the right and left rear wheels through the use of two motors installed in the rear.


Engine Technology

Gasoline engines that are top-class on a global scale in terms of driving and fuel economy

660cc class Gasoline engine

Improved intake efficiency through the use of DOHC and VTC (Variable Timing Control), and achievement of 15%2 or greater reduction in weight and 10%2 improvement in fuel economy with the engine alone through reduction of the bore pitch and the thickness of the cylinder block and camshaft.

1.5L class Gasoline engine

Extensive friction reduction measures achieved through the use of VTC based on DOHC and VTEC technology, as well as either cooled EGR (Exhaust Gas Recirculation) technology with the Atkinson cycle, or high-capacity EGR technology with direct-injection technology for either hybrid or gasoline vehicles.

2.0L class Gasoline engine

Extensive friction reduction measures achieved through the use of the Atkinson cycle based on DOHC and VTEC technology, as well as the introduction of electronic VTC technology and cooled EGR technology for intake port.

2.4L class Gasoline engine

In comparison to current engines, improved fuel efficiency and output by 5%2 and maximum torque by 10%2 with the engine alone through extensive friction reduction measures and adoption of electronic VTC and direct-injection technology based on DOHC and VTEC for intake port.


3.5L class V6 Gasoline engine

img_12

The V6 i-VTEC engine uses cylinder deactivation technology and electronic VCM. For it, Honda has newly adopted a three-stage VTEC, which not only deactivates three cylinders on one bank of the V6, but also switches between low- and high-revolution valve timing. The engine improves on both low- and mid-speed torque as well as output, and enables both strong and smooth acceleration together with excellent cruising fuel economy. The engine alone offers a 10%2 or greater improvement in fuel economy and a 5%*2 or greater improvement in output compared to current engines.

1.6L class Diesel engine i-DTEC

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. Mechanical friction was reduced extensively in each section to achieve a low level of friction equivalent to present gasoline engine models.

EV (Electric Vehicle) Technology

A compact, high efficiency electric powertrain for EVs

Top class electrical consumption rate in the world in terms of the required rates in Japan and the U.S. due to factors including a high efficiency coaxial motor, a low-friction gearbox, and an electric servo brake system.


Transmission Technology

CVT that achieves a high level in both the fun of driving and fuel economy

An exhilarating, sporty drive is achieved through elements including a wide ratio range realized by a reinforced belt, and through G-Design Shift, a new coordinated control system for shift transmission, throttle, and hydraulic control. Fuel economy has been improved due to factors including an idle stop system with high response achieved by adopting a high-precision hydraulic control system and an electronic oil pump.

Honda has developed CVT structures that can be adopted for a variety of different engines.

Mini-vehicle class CVT

img_07

A lightweight and compact body is achieved through a reduction in parts accomplished by factors including simplifying the transmission casing structure and reducing the engine size lengthwise with a control mechanism and innovations in axle placement.

Compact class CVT

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 around 5%*2 compared to conventional CVT and around 10%*2 compared to 5ATs in its class.
