Mazda Reveals Upgraded e-Skyactiv X Engines

Mazda today announced that the 2021 Mazda3 and CX-30 models will be getting an upgraded version of its e-Skyactiv X SPCCI (Spark Controlled Compression Ignition) petrol engine in Europe.

The performance of the upgraded e-Skyactiv X unite engine has been improved to generate an extra 6 PS of power and 16 Nm of torque. Torque and output have improved in almost all engine speed ranges, and torque most noticeably under acceleration from low revs. The Mazda3 and CX-30 e-Skyactiv X now delivers 186 PS at 6,000 rpm and maximum torque of 240 Nm at 4,000 rpm.

A world’s first

Mazda’s new 2.0 litre e-Skyactiv X engine is in fact the world’s first production petrol unit to exploit the benefits of diesel-like compression ignition. Following the introduction of Skyactiv engine technologies in 2012, e-Skyactiv X represents Mazda’s second step towards the development of the ideal internal combustion engine.

The e-Skyactiv X engine also features Mazda’s revolutionary Spark Controlled Compression Ignition (SPCCI). This new engineering concept allows the engine to switch seamlessly between conventional spark ignition and compression ignition combustion by using a spark to trigger both types of combustion in different ways.

SPCCI mode

In SPCCI mode, a split injection process creates separate zones of fuel-air mixture inside the combustion chamber. First, a very lean fuel to air mixture is injected into the combustion chamber during the intake stroke, then a zone of atomised fuel is precisely injected directly around the spark plug during the compression stroke.

The small injection of atomised fuel directly around the spark plug builds a richer core. When the spark fires, it ignites this core of fuel and air. This increases pressure in the combustion chamber to the point where the lean mixture rapidly combusts.

Allowing the engine to run for a high percentage of time in a very efficient mode, SPCCI works in almost all ranges of engine operation except during cold starts, initial warm-up phases and at very high load. Under these circumstances, the engine seamlessly switches to normal operation, igniting a conventional stoichiometric air and fuel mixture of 14.7:1.

Improvements in both power and efficiency have been achieved through adjusting e-Skyactiv X’s compression ratio from 16.3:1 to 15.0:1.

Modifications include the optimisation of combustion control, modified pistons, and the updating of the Mazda M Hybrid system software. Fitted as standard, the e-Skyactiv X’s Mazda M Hybrid system further enhances both efficiency and driving comfort.

This not only results in a broader operating band of combustion efficiency, but also effects even higher ignition stability – further minimising the already very low risk of unexpected self-ignition or pre-ignition due to the variability of fuel quality in different markets.


Mazda says that the e-Skyactiv X engine on the Mazda3 and the CX-30 will be available with either Skyactiv-MT 6-speed manual transmission (6MT) or Skyactiv-Drive 6-speed automatic transmission (6AT). The powertrain line-up features front-wheel-drive (FWD) as standard, with Mazda’s unique i-Activ all-wheel-drive (AWD) optionally available for Mazda3 hatchback variants and the CX-30.

At the moment, the new engines are only destined for Europe and a few selected markets. Whether they will come to Malaysia remains a question, so watch this space for more updates on the new engines.

Recall Alert: Mazda2, Mazda3, Mazda6, CX-3, CX-5, CX-9 – Fuel Pump Issues

mazda recall

Mazda Corporation has announced a product recall to replace its fuel delivery module (fuel pump) as a precautionary measure.

A total of 19,685 units of Mazda vehicles in Malaysia that were manufactured between year 2017 and 2019 are affected in the product recall. The models affected are:

  • Mazda2 – 2,028 units
  • Mazda3 – 1,441 units
  • Mazda6 – 13 units
  • Mazda CX-3 – 381 units
  • Mazda CX-5 – 15,780 units
  • Mazda CX-9 – 42 units

Bermaz Motor also mentioned that all year 2020 production models are not affected in this product recall.

This product recall is necessary as a preventive measure to address the possibility of loss of engine power or vehicle stalling caused by the fuel pump module.

Affected customers will be informed via notification letters and mobile SMS, which will include details of the product recall. Upon receipt of notification to replace the fuel pump, Bermaz Motor urges all affected customers to contact any Bermaz authorized service centres to make an appointment.

The replacement of the affected fuel pump is free of charge and all costs related to this replacement activity will be borne by Bermaz Motor.

The duration of repair service is estimated to take approximately 1.5 hours or slightly longer depending on the model and the service centre workload at the time of appointment. The replacement stocks will be available in stages.
