Next-Generation ‘SKYACTIV’ Technologies

SKYACTIV is a brand name for a series of technologies which increases fuel efficiency and engine output.

Some Highlights:

  • SKYACTIV-G: direct-injection gasoline engine with till date’s highest compression ratio of 14.0:1

  • SKYACTIV-D: diesel engine with the world’s lowest compression ratio of 14.0:1

  • SKYACTIV-Drive: highly-efficient automatic transmission

  • Manual transmission with compact size, a light shift feel and significantly reduced weight

  • Lightweight, highly-rigid body and excellent crash safety performance

  • High-performance lightweight chassis with precise handling and a comfortable ride

SKYACTIV technologies- An Overview

1. SKYACTIV-GHighly-efficient direct-injection gasoline engine that attainsthe highest gasoline engine compression ratio of 14.0:1 with zero knocking.

  • It is used for mass production of vehicles to achieve a high compression ratio

  • An improved engine efficiency owing to the high compression combustion, that results in 15 percent increase in fuel efficiency and torque.

  • A 4-2-1 exhaust system, multi-hole injectors, cavity pistons and other innovations help in achieving the high compression ratio.

2. SKYACTIV-DA clean diesel engine which would meet global emissions regulations without costly NOx after treatments — urea selective catalytic reduction (SCR) or a Lean NOx Trap (LNT) — owing to the world’s lowest diesel engine compression ratio of 14.0:1

  • 20 percent better fuel efficiency

  • A novel two-stage turbocharger realizes smooth and linear response from low to high engine speeds and greatly increases low- and high-end torque

  • Follows global emissions regulations, without expensive NOx after treatment

3. SKYACTIV-Drive
Highly efficient automatic transmission that achieves excellent torque transfer efficiency through a wider lock-up range and features the bestfeatures of all transmission types

  • It has all the benefits of traditional automatic transmissions,consistently variable transmissions, and dual clutch transmissions

  • A dramatically widened lock-up range upgrades torque transfer efficiency and realizes a direct driving feel that is equivalent to a manual transmission

  • A 4-to-7 percent improvement in fuel economy in comparison to the current transmission

4. SKYACTIV-MTA light and compact manual transmission with crispy and light shift feel like that of a sports car.

  • Short stroke and gives a light shift feel

  • Reduced size and weight due to a revised structure

  • More efficient vehicle packaging owing to its compact size

  • Reduced internal friction leads to economical fuel efficiency

5. SKYACTIV-BodyA lightweight, highly-rigid body with an excellent crash safety execution and high rigidity for greater driving pleasure

  • Highly rigid and lightness

  • Excellent crash safety performance and lightness

  • A “straight structure” in which each part of the frame is configured to be as straight as possible. Moreover, a “continuous framework” approach was adopted in which each section functions in a coordinated manner with the other connecting sections

6. SKYACTIV-ChassisHigh-performance lightweight chassis which balances precise handling with a comfortable ride feel to realize pleasure duringdriving.
