2018 Mazda 3 will introduce new SkyActiv HCCI engine

The reason why 2017 Mazda 3 didn’t receive any major updates lies in a fact that new model brings much more advancements. Well, if sources are to be believed. When we say major updates, we firstly think about engine department. We all know what carmaker is in question when someone mentions SkyActiv technology. With it, Mazda managed to improve fuel efficiency. And according to several sources, one is from Japan, 2018 Mazda 3 will be the first vehicle in the Mazda lineup to receive all new second generation SkyActiv engine. Even with this update, we don’t think that new Mazda 3 will be next generation. But we won’t talk about 2018 Mazda 3. Let’s talk about what kind of engine will lie under the hood.

SkyActiv HCCI – What Is It?

Now imagine a gasoline powered internal combustion engine without spark plugs. Imagine fuel efficiency of a diesel engine in gasoline one. Tough. But Mazda said that second generation of SkyActiv engines will 30% better fuel efficiency. And how will this be done? It’s called homogeneous charge compression ignition (HCCI). It means that instead of using spark plugs to ignite fuel than by using pressure. In other words, it is a gasoline powered engine with the ignition system of a diesel one. Amongst other manufacturers that have pursued this technology, Mercedes-Benz was the one to unveil it in 2007 in F700 Concept. But other than that no one built a production-ready version of this engine. Even while every carmaker goes into electrifying their models, we all know that combustion engines are here to stay. At least for next fifteen years.

Why’s It Good?

There are several benefits of this engine. And most notable one is, as we said earlier, much better fuel consumption. If the calculations are correct, new SkyActiv engine will have fuel consumption as low as it can be. Just for the reminder the current Mazda 3 has fuel consumption rated at 41 mpg. And with a new engine, that number would rise to 71 mpg. Now we can compare that with Prius’ 69 mpg and we can see what achievement this would be for the Japanese engineers. If all goes well, this engine will find its place under the hoods of all future vehicles in Mazda lineup.
