Next-Generation ‘SKYACTIV’ Technologies



Highlights of the SKYACTIV technologies:
SKYACTIV-G: a next-generation highly-efficient direct-injection gasoline engine with the world’s highest compression ratio of 14.0:1
SKYACTIV-D: a next-generation clean diesel engine with the world’s lowest compression ratio of 14.0:1
SKYACTIV-Drive: a next-generation highly-efficient automatic transmission
A next-generation manual transmission with a light shift feel, compact size and significantly reduced weight
A next-generation lightweight, highly-rigid body with outstanding crash safety performance
A next-generation high-performance lightweight chassis that balances precise handling with a comfortable ride

- First product to be equipped with SKYACTIV technology will be a Mazda Demio featuring an improved, fuel-efficient, next-generation direct-injection engine that achieves fuel economy of 30 km/L.



Overview of the SKYACTIV technologies
1. SKYACTIV-G
A next-generation highly-efficient direct-injection gasoline engine that achieves the world’s highest gasoline engine compression ratio of 14.0:1 with no abnormal combustion (knocking)
The world’s first gasoline engine for mass production vehicles to achieve a high compression ratio of 14.0:1
Significantly improved engine efficiency thanks to the high compression combustion, resulting in 15 percent increases in fuel efficiency and torque
Improved everyday driving thanks to increased torque at low- to mid-engine speeds
A 4-2-1 exhaust system, cavity pistons, multi hole injectors and other innovations enable the high compression ratio
2. SKYACTIV-D
A next-generation clean diesel engine that will meet global emissions regulations without expensive NOx after treatments — urea selective catalytic reduction (SCR) or a Lean NOx Trap (LNT) — thanks to the world’s lowest diesel engine compression ratio of 14.0:1
20 percent better fuel efficiency thanks to the low compression ratio of 14.0:1
A new two-stage turbocharger realizes smooth and linear response from low to high engine speeds, and greatly increases low- and high-end torque (up to the 5,200 rpm rev limit)
Complies with global emissions regulations (Euro6 in Europe, Tier2Bin5 in North America, and the Post New Long-Term Regulations in Japan), without expensive NOx after treatment
3. SKYACTIV-Drive
A next-generation highly efficient automatic transmission that achieves excellent torque transfer efficiency through a wider lock-up range and features the best attributes of all transmission types
Combines all the advantages of conventional automatic transmissions, continuously variable transmissions, and dual clutch transmissions
A dramatically widened lock-up range improves 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 compared to the current transmission
4. SKYACTIV-MT
A light and compact next-generation manual transmission with crisp and light shift feel like that of a sports car, optimized for a front-engine front-wheel-drive layout
Short stroke and light shift feel
Significantly reduced size and weight due to a revised structure
More efficient vehicle packaging thanks to its compact size
Improved fuel economy due to reduced internal friction
5. SKYACTIV-Body
A next-generation lightweight, highly-rigid body with outstanding crash safety performance and high rigidity for greater driving pleasure
High rigidity and lightness (8 percent lighter, 30 percent more rigid)
Outstanding crash safety performance and lightness
A "straight structure" in which each part of the frame is configured to be as straight as possible. Additionally, a "continuous framework" approach was adopted in which each section functions in a coordinated manner with the other connecting sections
Reduced weight through optimized bonding methods and expanded use of high-tensile steel
6. SKYACTIV-Chassis
A next-generation high-performance lightweight chassis that balances precise handling with a comfortable ride feel to realize driving pleasure
Newly developed front strut and rear multilink suspension ensures high rigidity and lightness (The entire chassis is 14 percent lighter than the previous version.)
Mid-speed agility and high-speed stability — enhanced ride quality at all speeds achieved through a revision of the functional allocation of all the suspension and steering components
