Following a selection of all-new MY25 medium-duty F Series Isuzu models already going on sale across Australia, Isuzu Trucks has also released the next round of models including the four-cylinder F Series range.
Including popular variants from the FRR, FSR, FRD and FSD line-ups plus the FSS 4×4, the brand’s phase-two launch completes the circle from a medium-duty perspective.
Capturing the 11 to 14 tonne Gross Vehicle Mass (GVM) band, the 2025 F Series release broadens opportunities for a wide variety of applications and industries across the country.
Reflecting on the sustained demand throughout this weight category, Isuzu Australia head of sales Craig White says the versatility of this model release was a crucial ingredient.
“Our four-cylinder F Series release has been highly anticipated, both from an OE point of view and for our many customers in this market segment,” White says.
“These models really are the operational ‘sweet-spot’ for so many general and hub & spoke freight applications, so we’re thrilled to see them in the country and on-grass in dealerships across the country.
“Taking into account critical factors such as engine output, payloads and wheelbase options, the flexibility and adaptability of these models can’t be understated.
“They represent the backbone of what’s required to continue to tackle Australia’s surging freight task. Add to that the heady mix of features and benefits found throughout this release and we’re confident we’ve got the answers in the form of these all-new models.”
The phase-two F Series encompass a pivotal GVM spectrum, commencing at 11,000 kilograms with its FRR and FRD models along with the FSS 4X4, and culminating at 14,000 kilograms with the FSR and FSD variants.
The offering includes Crew Cab and a selection of wheelbase options plus two rear suspension options, delivering fit-for-purpose road transport flexibility to Australian industry.
Across the F Series range, there’s two Japanese-made engines that provide the grunt behind the lineup.
The primary power source for the entire range is a pPNLT variant of the Isuzu 4HK1 power plant. FRR, FRD, FSR, and FSD models use the 4HK1-TCH, a lightweight, high-torque, and fuel-efficient engine rated at 240 PS. For the 4×4 FSS model four-cylinder powerplant: a unique 4HK1-TCS is selected, which produces 210 PS.
To meet the now mandated ADR80/04 regulation, the F Series 4HK1, emission levels are achieved through an advanced post-Post New Long Term (pPNLT) Japanese based standard using a combination of after-treatment systems, new to the range in 2025.
This system combines a Diesel Particulate Diffuser (DPD) to capture particulate matter with a Selective Catalytic Reduction (SCR) unit to mitigate nitrogen oxides (NOx). The introduction of a dosing unit injects AdBlue, which chemically reduces NOx emissions, resulting in a final exhaust output composed predominantly of an inert mix of water vapour and nitrogen gas.
Isuzu’s robust six-speed manual transmission is available across select models and remains a preferred choice for tipper and 4×4 applications.
Another key trait common amongst the entire Isuzu range is an entirely re-designed cabin exterior and interior, applying a focus to driver comfort and wellbeing.
According to White, this in concert with the array of improvements to these stalwart models, developing a blueprint for operational success, efficiency and talent retention.
“We know how critical this segment is to operators and indeed, to the overall functioning of Australia’s supply chain,” he says.
“That’s why with this release, there’s been a heavy weighting towards not only optimum performance and flexibility but also a steadfast focus on driver comfort, safety and wellbeing.
“As we know, without a driving workforce, Australia just stops, so we’ve been extremely conscious of developing a solution in this space that promotes and elevates a safe and relaxed driving environment.”
