Isuzu UTE Australia will introduce a new 2.2-litre turbo-diesel engine across its D-MAX ute and MU-X seven-seat SUV range from October 1, 2025, replacing the outgoing 1.9-litre motor.

The four-cylinder EURO5 RZ4F-TC engine produces 120kW and 400Nm, a step up from the 1.9-litre unit’s 110kW/350Nm output. Torque delivery has also been improved, with 255Nm available from just 1,000rpm and peak torque arriving between 1,600 and 2,400rpm. According to Isuzu, combined fuel consumption is rated from 6.3L/100km.

The new engine will be paired exclusively with an eight-speed automatic transmission, ending manual transmission availability across the range. For the D-MAX, the 2.2L will be offered in SX and X-Rider variants, while MU-X customers will see it in LS-M, LS-U and LS-T grades.

Importantly, the change means that every D-MAX and MU-X variant now offers 3.5-tonne braked towing capacity, aligning the smaller engine option with the long-established 3.0-litre four-cylinder (140kW/450Nm) available in higher trims. All 2.2L-equipped models continue to carry a five-star ANCAP safety rating.

The addition of the new powertrain also coincides with a colour update, with Wolfram Grey Metallic replacing Granite Grey in the D-MAX palette for X-Rider and higher trims. In total, the 25.5MY D-MAX will offer nine exterior colours, while the MU-X will feature eight.

Isuzu UTE Australia managing director Junta Matsui said the decision to replace the 1.9L engine with the more powerful 2.2L reflected customer feedback and market demands. “Our focus has always been on value, durability and performance,” he said. “This update ensures our vehicles remain suited to Australian conditions and customer expectations.”

The new engine joins the D-MAX and MU-X line-up after a strong sales run for Isuzu UTE in Australia. The brand finished in the national top 10 for annual sales in 2024, with the D-MAX ranked as the country’s fourth best-selling vehicle.

With the introduction of the 2.2-litre diesel, Isuzu aims to offer a more efficient alternative for buyers seeking lower running costs while retaining full towing and load capacity, alongside the proven 3.0-litre option already in the range.
