Up to 20% less fuel consumption with 30% more torque

Skyactiv-X is Mazda's revolutionary new petrol engine, which produces high power, with low emissions.

More enjoyable to drive, with less fuel, the Skyactiv-X relies on a Mazda-patented technology called Spark Controlled Compression Ignition (SPCCI) which burns petrol more efficiently.

It makes more power but produces fewer emissions and uses less fuel than a regular petrol engine for an even better drive without compromise.

Skyactiv-X is the first consumer petrol engine with SPCCI, which combines the best of two worlds:

The advantages of petrol and diesel technology in one motor which features direct and smooth response, powerful and high torque with outstanding fuel economy and emission values.

An extremely lean mix of fuel and air are compressed to an extremely high pressure.

A spark then ignites a very small, dense amount of fuel, which further raises the heat and pressure in the cylinder, causing the remaining fuel to ignite under pressure (like a diesel).The fuel burns more quickly and more completely so you get better performance and fewer emissions than a conventional engine. A normal petrol engine mixes air and petrol at the ratio of 14.7:1, but Skyactiv uses an incredibly lean mix of up to 40:1 when running in SPCCI mode.

More air, less fuel,better economy and more power.

Most of the time it will run in SPCCI mode for maximum efficiency, but when you want to get the most of the power available the engine will seamlessly switch to a spark ignition mode, offering an exhilarating free-revving performance.

A small supercharger helps to pressurise the air in the engine when running in SPCCI mode, there is no lag, just an intuitive surge of power all the way to the red line.

SPCCI combines the fuel-efficiency of a diesel with the power and drivability of a petrol engine.

The engine switches seamlessly between conventional spark ignition and a compression ignition mode where a lean fuel-air mix is compressed so that it will combust even more efficiently. It’s the best of both worlds.

Mazda's mild hybrid technology uses a small Integrated Starter Generator (ISG) to capture energy that is normally wasted during braking and stores it to power the car’s electrical systems, reducing the load on the engine and saving fuel in the process.

The battery charges when you drive – but only when you slow down, so it never takes power away from the engine.


Mazda M Hybrid is standard on all petrol-powered Mazda3 and Mazda CX-30 models, including Skyactiv-X vehicles. When you decelerate the integrated starter motor generator produces electricity which is stored in a 24 volt battery.

This electricity is used for a number of purposes including starting the engine and giving a small boost when you pull away. It can also power the car’s electrical systems.

You may notice that you drive more smoothly with the electric motor assistance pulling away from a standstill is easier, and when you change gear the motor also supplies a boost which makes gear changes smoother.

Figures shown are for comparability purposes; only compare fuel consumption and CO₂ figures with other cars tested to the same technical procedures. These figures may not reflect real life driving results, which will depend upon a number of factors including the accessories fitted (post-registration), variations in weather, driving styles and vehicle load. There is a new test used for fuel consumption and CO₂ figures. The CO₂ figures shown however, are based on the outgoing test cycle and will be used to calculate vehicle tax on first registration.
