Mazda unveils new Mazda3; first production car to offer Skyactiv-X SPCCI engine with M Hybrid system

In Japan, Mazda Motor Corporation hosted the world premiere of the all-new Mazda3. The fully redesigned model will be rolled out to global markets starting from North America in early 2019. The all-new Mazda3 will be on display at the Los Angeles Auto Show.


The all-new Mazda3 adopts Mazda’s new Skyactiv-Vehicle Architecture, designed to enable people to make the most of their natural sense of balance. The powertrain lineup comprises the latest Skyactiv-X (Mazda’s Spark Controlled Compression Ignition (SPCCI) engine, earlier post), Skyactiv-G and Skyactiv-D engines, each of which provides responsive speed control in any driving situation. Mazda has enhanced the car’s fundamental driving attributes such that accelerating, turning and braking feel completely natural.

  • All-new Mazda3 is the first production car to offer Mazda’s innovative Skyactiv-X engine. Running on regular gasoline, SPCCI works by compressing the fuel-air mix at a much higher compression ratio, with a very lean mix. The SKYACTIV-X engine uses a spark to ignite only a small, dense amount of the fuel-air mix in the cylinder. This raises the temperature and pressure so that the remaining fuel-air mix ignites under pressure (like a diesel), burning faster and more completely than in conventional engines.

    Features include superior initial response, powerful torque, faithful linear response and free-revving performance. The engine is assisted by Mazda’s intelligent new M Hybrid system, which supports greater gains in fuel economy, and achieves higher levels of driving pleasure and environmental friendliness.

  • 5-, 2.0- and 2.5-liter versions of the latest Skyactiv-G comprise the gasoline engine lineup for the new Mazda3. All three adopt optimized intake ports and piston shape, split fuel injection and a coolant control valve to deliver higher levels of dynamic performance, fuel economy and environmental friendliness.

  • The Skyactiv-D 1.8 is the diesel engine offering for the new Mazda3. Incorporating ultra-high-response multi-hole piezo injectors allows the engine to utilize high-pressure, precisely controlled multi-stage injection. This realizes a finer balance of enhanced fuel economy, quietness and reduced exhaust gases, while also delivering smoother, more robust performance.

Mazda’s evolved i-Activ AWD newly adds four-wheel vertical load detection and works in harmony with G-Vectoring Control Plus (GVC Plus) to control torque distribution between the front and rear wheels. As a result, it is fully capable of responding faithfully to the driver’s intentions, regardless of the driving scene. It also reduces overall mechanical loss by approximately 60% over the previous model and contributes to improved fuel economy.

G-Vectoring Control Plus (GVC Plus) adds direct yaw moment control via the brakes. This enables the car to better handle emergency avoidance maneuvers and offers more confidence-inspiring controllability in various situations, including lane changes at high speeds and driving on slippery roads.

Having sold over 6 million units since its 2003 debut, the all-new Mazda3 is a global strategic model that has driven Mazda’s growth from both a brand and business perspective.



Nice car and mechanics; but, obsoleted by the new BEVs.


Sounds very much like any sales spiel. Lots of hype and technical sounding jargon but no details. What are horsepower, torque and fuel mileage? And price.


Skyactiv-X needs supercharger to work properly, I'm afraid that that will rob the benefited efficiency from HCCI.


Skyactiv-X thermal efficiency is impressive,
it would make a good flex fuel PHEV.
