Mazda has updated the 3 and CX-30 for 2025 with an enhanced specification and new powertrain.

The existing 2.0-litre four-cylinder engine in e-Skyactiv G models, has been replaced by a new 2.5-litre unit.

The new engine features cylinder de-activation and the Mazda M-Hybrid mild-hybrid system.

It develops 140PS and emits from 133g/km of CO2.

Mazda also offers both cars with its 186PS e-Skyactiv-X engine, which can be paired with all-wheel-drive on the CX-30.

Both models leave their exterior design and interiors unchanged, but all 2025 Mazda 3s and Mazda CX-30s now feature integrated Alexa Voice Assistant, while the Mazda navigation system benefits from cloud-based points of interest and database updates.

The Mazda 3 Saloon comes exclusively with the 186PS e-Skyactiv X engine, but for the 2025 model year is solely offered in Exclusive-Line grade.

Jeremy Thomson, managing director of Mazda UK, said: “The addition of the 2.5-litre e-Skyactiv G engine with its cylinder deactivation to Mazda3 and Mazda CX-30 is part of our multi-solution approach to powertrains and sustainability that also features e-Skyactiv X with its SPCCI technology in Mazda3 and Mazda CX-30, plus the wide adaption of Mazda M Hybrid mild-hybrid across our models. Moreover, models like the Mazda2 Hybrid, Mazda MX-30 R-EV and the Mazda CX-60 PHEV also further highlight our multi-solution approach.”

2025 model year versions of the Mazda 3 are available to order now, while orders for the 2025 Mazda CX-30 follow later this autumn.
