Isuzu's popular D-Max and MU-X models are poised for a significant mid-life update in 2025, featuring an all-new 2.2-litre four-cylinder turbo-diesel engine equipped with mild-hybrid technology. The development, reported by Thailand's Headlight magazine, outlines Isuzu's plan to introduce this innovative powertrain to the D-Max ute initially, followed by its SUV counterpart, the MU-X.
The forthcoming 2.2-litre engine represents an evolution of the existing 1.9-litre turbo-diesel engine, which made its debut in the Australian D-Max range in January 2022. As of December 2023, the MU-X is expected to adopt the 1.9-litre engine in 2024.
It remains uncertain whether the introduction of the 2.2-litre mild-hybrid engine will replace the existing 1.9-litre or 3.0-litre engines in Isuzu's lineup or be presented as an additional option for consumers.
In Australia, the current entry-level 1.9-litre turbo-diesel engine produces 150 horsepower and 350 Nm of torque, while the range-topping 3.0-litre turbo-diesel engine generates 190 horsepower and 450 Nm of torque.
According to the report, the 2.2-litre engine will leverage the mild-hybrid system to mitigate turbo lag during take-off and deliver enhanced performance in short bursts, such as uphill acceleration or overtaking maneuvers.
This strategic move by Isuzu to incorporate mild-hybrid technology into its D-Max and MU-X models is seen as a response to the evolving market landscape, particularly with the impending launch of the mild-hybrid Toyota HiLux in 2024. Ford is also set to introduce a plug-in hybrid Ranger ute from 2025, and Mitsubishi is anticipated to debut its own hybrid version of the upcoming Triton ute.
The mild-hybrid system, as per the report, is expected to feature an electric motor connected to the engine through a belt, serving dual roles as a starter motor and generator – a setup similar to that of the Toyota HiLux.
While Isuzu is making strides in hybrid technology, it's worth noting that the brand is set to launch its first electric ute in Norway in 2025, with plans to extend availability to the Thai and possibly Australian markets. However, local sales might not commence until
2027.
