SkyActiv

SkyActiv is Mazda's umbrella term for a family of technologies designed to increase fuel efficiency and performance by optimizing engines, transmissions, and vehicle architecture. Introduced in the early 2010s, SkyActiv includes enhancements across powertrain and chassis work aimed at greater real-world efficiency without relying on hybrid systems.

SkyActiv-G refers to Mazda's direct-injected gasoline engines, which use high compression ratios and refined combustion to boost thermal efficiency and torque at low rpm. SkyActiv-D refers to Mazda's diesel engines, which employ turbocharging, efficient combustion, and advanced exhaust treatment to reduce emissions while delivering high efficiency.

SkyActiv-Drive is an automatic transmission designed to minimize energy losses while providing smooth, responsive gear changes, while SkyActiv-MT is a lightweight manual transmission aimed at reducing mass and friction for better efficiency and driving engagement.

SkyActiv-Body and SkyActiv-Chassis describe Mazda's approach to vehicle structure and suspension: using high-tensile steel, optimized rigidity, and weight reduction, alongside chassis tuning for a confident yet comfortable ride.

Mazda introduced SkyActiv in models such as the CX-5 and Mazda3 around 2012–2013, with subsequent adoption across many Mazda passenger cars and SUVs. The brand later expanded the concept to SkyActiv-X, a spark-ignition engine that employs compression ignition principles, continuing the emphasis on efficient powertrains within the SkyActiv family.
