What are the scientific and technical innovations that for the basis for Mazda's claims of improved performance? Is this actually a technical innovation, or simply a marketing pitch? Have independent measurements verified specific performance improvements? Thanks! -- Lbeaumont ( talk) 11:25, 22 August 2014 (UTC)
Beginner here so I apologize for the formatting. Increasing the compression increases the efficiency (per physics/thermodynamics manual) but more than that it's the fact that the engine functions as a variable compression engine in which the actual compression ratio is adapted to the demands. A light load works best with low compression and vice versa. So, the theory says IT SHOULD BE more efficient at both light and heavy loads. — Preceding

I feel that this article should be split into separate articles; i.e. Mazda SKYACTIV-G engine, Mazda SKYACTIV-D engine, etc. Regards, VX1NG ( talk) 17:27, 26 September 2014 (UTC)
The reference to manual transmission features makes comment on shift throws, etc. but leaves out any detail on the number of speeds and does not specify any ratios. — Preceding unsigned comment added by Homebuilding ( talk • contribs) 02:47, 20 February 2017 (UTC)
“ In the aftermath of the Volkswagen emissions scandal, the Japanese government performed testing of all diesel engines produced in Japan to ensure Japanese manufacturers were not falsifying emissions as had been done by Volkswagen. It was determined that the Skyactiv-D engine was the only engine which tested at or near the standard.”
This graph says otherwise

Or was this speculation by media journalists upon interpreting a photo release by mazda (of three engines)? In March 2022, they seems to be certain that the petrol offering was three litre Sky-X but seven months later, in October 2022, Car Scoops (correctly) revealed that the petrol engine would be a 3.3 Sky-G. Perhaps the US is getting a special version in addition to the others? If there is no evidence of the existence of the 3.0, this should be scrubbed from the article.
