The 2021 model year versions of the Mazda CX-30 and Mazda3 see the debut of the updated version of Mazda’s unique Skyactiv X SPCCI (Spark Controlled Compression Ignition ) petrol engine.
It is renamed e-Skyactiv X, the updated version delivers increased performance and even more efficiency.
The latest 2.0-litre e-Skyactiv X engine produces a claimed 186ps at 6,000rpm and maximum torque of 240Nm at 4,000rpm an increase of 6ps and 16Nm respectively.
Mazda says that the torque improvement is most noticeable from 2000rpm onwards, however it adds that the 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.
It also claims that even better, efficiency has also been improved, with CO2 emissions dropping by 5 to 11 g/km - depending on model, transmission and trim level. Adding that a corresponding improvement in WLTP combined economy further increases the appeal of Mazda’s unique SPCCI petrol engine.
Additionally to the updates to the combustion engine, Mazda says that their M Hybrid mild-hybrid system has had a software update that enables faster reactions of the system’s belt-driven ISGs torque control.
It adds that 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.
In addition, it claims that the 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, it boasts that 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 is moving to e-Skyactiv G naming and across the CX-30’s 122ps 2.0-litre range CO2 has been reduced by 7-8g/km.
On sale now, the 2021 Mazda CX-30 line-up feature a choice of e-Skyactiv X or e-Skyactiv G models, which are offered exclusively with front-wheel drive. GT Sport grades are also available with Mazda’s advanced all-wheel drive system with the e-Skyactiv X engine, in either manual or automatic transmission.
Also, recently on sale from the March 1, the 2021 Mazda3 sees the same upgraded e-Skyactiv X engine and benefits from 5-11 g/km CO2 reductions alongside the same power and torque improvements.
It concludes by saying that the stylish 2021 Mazda3 Saloon is offered exclusively with the e-Skyactiv X engine with the hatchback available in both e-Skyactiv X and e-Skyactiv G.
