Mazda has debuted its new 1.8-litre diesel engine in the updated CX-3 compact SUV, which is now available to order in Japan ahead of its European launch later this year.

The engine debuts in the updated Mazda CX-3

Revealed at the New York International Auto Show in April, the visual upgrades are – in typical Mazda style – very light, comprising new rear lights, an additional paint colour and a new wheel design. The CX-3 also gets subtle interior updates, including moving to an electric parking brake for the first time.

The brand’s new 1.8-litre diesel engine also makes its debut in its home market – unusually, considering Japan’s stringent emissions limits, which have made the fuel a small seller. This produces 116hp – up from 105hp for the 1.5-litre unit it replaces – though with the same 270Nm torque, available over a wider 1,600-2,600rpm rev range.

Mazda claims the new diesel unit offers better real-world fuel economy, while also meeting the latest Euro 6d Temp emissions standards, and complying with the still-optional Real Driving Emissions Step 1 on-road test. The engine is likely to feature in the next Mazda3, and could also be introduced as an entry-level unit for the Mazda6, though neither have been confirmed.

For 2018, Mazda has also fine-tuned the suspension, added extra sound deadening, redesigned the seat foam for added thicker glass, and changed the tyres on 18-inch wheels, all aimed at offering a quieter and more comfortable drive. New technology includes the ability to detect pedestrians at night.

European markets will get the new CX-3 from summer 2018.
