• Upgraded e-Skyactiv X engine features in the 2022 Mazda3 and 2022 Mazda CX-30.
• The 2.0-litre 186ps e-Skyactiv X has an extra 6ps, while torque has increased by 16Nm to 240Nm.
• 2022 Mazda3 and 2022 Mazda CX-30 also offered with the 122ps e-Skyactiv-G engine.

The 2022 Mazda CX-30 and 2022 Mazda3 feature Mazda’s unique Skyactiv-X SPCCI Spark Controlled Compression Ignition petrol engine. Renamed e-Skyactiv X in 2021, the updated version delivers increased performance and even more efficiency.

The latest 2.0-litre e-Skyactiv X engine produces 186ps at 6,000rpm and maximum torque of 240Nm at 4,000rpm an increase of 6ps and 16Nm respectively compared to the previous Skyactiv-X engine. The torque improvement is most noticeable from 2000rpm onwards, however e-Skyactiv X’s torque output has improved in almost all engine speed ranges, and particularly under acceleration from partial-load driving situations most commonly found during daily driving. Even better, efficiency has been improved, with CO2 emissions dropping by 5 to 11g/km – depending on model, transmission and trim level. Corresponding improvement in WLTP combined economy further increases the appeal of Mazda’s unique SPCCI petrol engine.

As an example the AWD GT Sport CX-30 automatic now emits 11g/km less CO2 with a 2.4mpg improvement in combined WLTP economy, while the entry-level front-wheel drive manual SE-L Lux CX-30 is 6g/km cleaner and is 2.5mpg more fuel efficient. The updates to Mazda’s 2.0-litre Spark Controlled Compression Ignition engine were achieved through adjusting the compression ratio from 16.3:1 to 15.0:1, while other modifications included the optimisation of combustion control, modified pistons and updating the Mazda M Hybrid mild-hybrid system’s software.

This results in a broader operating band of combustion efficiency, which ensures e-Skyactiv X not only delivers higher maximum engine torque but also improved real-world fuel economy. The intake valve timing was adapted through modifying the intake camshaft, this lead to a reduction in pumping losses and further increases the engine’s specific heat ratio, resulting in improvements to the e-Skyactiv X’s fuel consumption.

In addition to the updates to the combustion engine, the Mazda M Hybrid mild-hybrid system had a software update which enables faster reactions of the system’s belt-driven ISGs torque control. This improvement on control smooths drivability by increasing or reducing torque control when needed. For example, when the e-Skyactiv X’s air supply unit turns on – to provide sufficient air needed for a lean combustion fuel-air mixture - or off again, the units inertia creates torque fluctuations. The Mazda M Hybrid’s enhanced software enables torque reactions issued through the belt-driven ISG that are quick enough to flatten the torque curve. As a result, the engine feels even smoother during linear acceleration.

Corresponding to the renaming of the e-Skyactiv X engine, Mazda’s 2.0-litre Skyactiv-G engine has moved to e-Skyactiv G naming and across the CX-30’s 122ps 2.0-litre range CO2 has been reduced by 7-8g/km compared with the previous Skyactiv-G engine.

The 2022 Mazda CX-30 line-up features nine e-Skyactiv G models, which are offered exclusively with front-wheel drive in SE-L, SE-L Lux, Sport Lux, GT Sport and GT Sport Tech trim levels with the option to go for an automatic transmission on all models with the exception of the entry-level SE-L. The 12-model e-Skyactiv X range sits across the SE-L Lux, Sport Lux, GT Sport, and GT Tech trim levels with the option of automatic transmission throughout the line-up. From GT Sport upwards there’s also the option to choose Mazda’s advanced all-wheel drive system.

The 2022 Mazda3 features the same upgraded e-Skyactiv X engine and benefits from 5-11g/km CO2 reductions alongside the same power and torque improvements. The eight-model 2.0-litre e-Skyactiv G line-up features SE-L, SE-L Lux, Sport Lux, GT Sport and GT Sport Tech trims with the option of an automatic gearbox on all but the entry-level SE-L. The e-Skyactiv X hatchback range features six cars across SE-L Lux, Sport Lux, GT Sport and GT Sport Tech trims with the option of an automatic gearbox from Sport Lux onwards. Additionally, the stylish 2022 Mazda3 Saloon is offered exclusively with the e-Skyactiv X engine with a nine model line-up.

Commenting on the 2022 Mazda3 and CX-30, Jeremy Thomson, Managing Director Mazda UK, said: “Our SPCCI engine technology is part of our multi-solution approach to powertrains and sustainability that has also seen the introduction of Mazda M Hybrid in Mazda3 and Mazda CX-30, plus the launch of the Mazda MX-30 – our first battery electric car. The updates to this technology with e-Skyactiv X has further enhanced the unique blend of performance and efficiency offered by our Skyactiv-X Technology. The Mazda CX-30 is now our best-selling car in the UK, and 47 per cent of CX-30s and Mazda3s sold in the UK feature the SPCCI engine.”
