Isuzu Trucks Unleashes Major MY25 Model Wave

Isuzu Australia Limited (IAL) has launched the second and arguably most significant phase of its MY25 model range, with a broad selection of light-duty N Series, medium-duty F Series and heavy-duty FY Series variants now on sale across Australia from November, 2025.

This major release, a core part of Isuzu's staged national roll-out, brings key models such as in-demand N Series Ready-to-Work range and multiple F Series configurations to market, expanding options for operators across critical Gross Vehicle Mass (GVM) bands.

Commenting on the major release, IAL Director and Chief Operating Officer, Andrew Harbison, said the phase-two milestone was an important step towards having the full MY25 range available for Australian customers.

“We’ve had some excellent feedback following of our stage-one model launch back in July, which encompassed N Series NQR models, a range of six-cylinder FV variants, along with heavy-duty FX models.

“This next phase is very exciting, as it opens up a significant number of models for Australian operators across a broader range of weight categories in both light and medium duty,” Mr. Harbison said.

“Of note is the long-awaited release of a large contingent of our N Series Ready-to-Work range, which we know is extremely popular and in high demand.

“Bringing a range of this breadth to market has been a generational task for our production and logistics teams, so together with our dealer partners, we’re extremely pleased to be able to open up even more possibilities for our customers, across a huge range of applications.” ​

N Series

Key N Series highlights: November release

Alongside Isuzu’s legendary product reliability, the brand’s steadfast focus on supplying an expansive range of fit-for-purpose capital equipment – has been central to its success. ​ ​

From breadth-of-range and class-leading engine and driveline componentry, through to improved cabin appointments, safety enhancements and Isuzu’s famous aftersales support - the Isuzu N Series positions one of the brand’s core products as the unmatched front-runner for Australia’s light-duty trade, construction and last mile delivery road transport needs.

From November, 2025, Isuzu customers can choose from an extensive list of newly released 4x2 N Series including all-new NLR, NNR, NPR and NMR models.

Across the stage-two N Series roll-out, GVM ratings begin at a driver’s licence friendly 4,500 kilograms, encompassing a large band of vehicles including multiple variations of the NLR, NNR, NMR and NPR models. Adding to its versatility are a range of vehicle types on offer, including Crew cab variants and a range of pre-built Ready-to-Work models. There’s also selection of wheelbase options available, providing true flexibility and fit-for-purpose end-use across Australian industry at large.

N Series engines

Engine options include two tried and tested Japanese-made, ADR compliant diesel power-plants with three power outputs that provide the horsepower behind the N Series range…

At the lighter end of the spectrum, various N Series models are equipped with Isuzu’s high torque, fuel efficient, turbocharged and inter-cooled light weight 4JZ1 engine, available with two power ratings, the TCS, which produces 110 kW (150 PS) at 2,800 RPM, and the TCH as found in some NPR models outputting 129 kW or 175 PS.

Rounding-out engine options in the N Series range is the higher output 4HK1-TCH engine providing 190 horsepower or 140 kilowatts at 2,600 RPM, which can be found in the NPR 70-190 models, matching the output of the NQR range released earlier in 2025.

Specified to reliably straddle the model line-up, these three engine variants complete a specification focussed on efficiency, performance and responsible emissions management.

N Series transmissions

Select models within the N Series 4x2 line-up now come equipped with Isuzu’s brand new MYR9S 9-speed dual clutch automated manual transmission, available on units powered by the 4JZ1 engine.

Designed and developed in-house by Isuzu engineers, this patented dual-clutch transmission features a wet clutch design producing smaller full-power gear steps along with a double overdrive 8th and 9th gear for almost unnoticeable shifting.

The MYR9S shifter also has a ‘P for park’ position with a park pawl for added ease of use and parking convenience.

The NPR models with 4HK1 engine remain with Isuzu’s two-pedal automated manual transmission, with improved electronics and shift quality, designed and engineered specifically for trucking applications, while manual transmissions can also be specified across most N Series models.

Key N Series Ready-to-Work highlights: Late 2025 Release

Far and away its most popular offering, Isuzu has consistently honed its Ready-to-Work offering to accommodate just about every application imaginable.

2025 is no exception and from the new cabin to a range of pre-built bodies, Isuzu has covered all bases to ensure every aspect, including intelligent engineering, advanced safety technology as well as a range of wheelbase options, remain at heart of this much-loved line-up.

With ever-popular Tradepack, Tipper, Servicepack and 4x4 variants expected to go on sale early next year, punters can still purchase a large section of the N Series RTW range with Isuzu’s stage-two model release seeing the return of the 4x2 N Series Traypack and Vanpack.

F Series

Key F Series highlights

With a GVM rating beginning at 11,000 kilograms, including several variations of the popular FRR and FRD, the stage-two F Series release tops-out at 14,000 kilograms GVM with FSR and FSD models, servicing a broad range of applications across this weight critical capacity.

In concert with its lighter N Series cousin, the sheer versatility of the 4-cylinder F Series range is central to its success. Vehicle types on offer include Day Cabs, Rest cabs and Crew Cabs, in addition to a selection of wheelbase options available, providing true flexibility and fit-for-purpose end-use across Australian industry at large.

F Series engines

Across the F Series range, there’s three Japanese-made engines that provide the grunt behind the lineup. ​

Fitted to the FRR, FRD, FSR and FSD models is Isuzu’s high torque, fuel efficient, light weight 4HK1-TCH engine, which produces 177 kW (240 PS) and a healthy 765 Nm of torque. ​ ​

Isuzu’s 4HK1-TCS variant of this four-cylinder powerplant can be found in the 4x4 FSS model, producing 154 kW (210 PS) and 706 Nm of torque. ​ ​

On the emissions front for the Isuzu 4HK1 engines used in F Series models, compliance to the latest ADR 80/04 emissions standard is achieved via a Diesel Particulate Diffuser (DPD) to reduce harmful particulate matter, combined with Exhaust Gas Recirculation (EGR) and a Selective Catalytic Reduction (SCR) system to reduce oxides of nitrogen or NOx.

The addition of a dosing unit using AdBlue ensures that the severity of harmful NOx emissions is reduced with the exhaust system ultimately producing far safer water vapour and nitrogen gas.

F Series transmissions

Across the F Series range, there’s a selection of transmissions specified to meet the needs and demands of Australian operations, from urban freight delivery to more bespoke applications and everything in between.

Isuzu’s six-speed MZW-6P Automated Manual Transmission, with both fully automatic and clutch-less manual operation modes, plus the added advantage of 145 per cent torque convertor multiplication for added acceleration, is found in most of these 4-Cylinder F Series models, designed and engineered specifically for trucking applications.

For those operators who still desire their own gear shifting, Isuzu’s six-speed, factory manual transmissions can be specified across select models where additional engine and rev control is required.

Key F Series Ready-to-Work Freightpack highlights: Late 2025 Release

The Ready-to-Work line-up’s offer for larger pallets and intra-urban delivery applications is bolstered with the FVL 260-300 AT 14 pallet MY25 Freightpack range, engineered to deliver greater efficiency, durability, and operational ease for the demanding medium-duty freight sector.

The MY25 FVL 260-300 AT FREIGHT-14 builds on Isuzu’s proven body formula with enhanced durability and a range of smart features including easy-glide curtains with quick-release latches, lightweight side gates, built-in load binders and an array of safety components from steps to grab handles and bright lighting.

FY Series

Key FY Series highlights

Rounding out the phase-two model release for Isuzu is the MY25 FY Series, with a total of 7 models available across the 32 tonne GVM line-up.

The versatile 8x4 FY is back better than ever, sporting a new ADR 80/04 compliant powerplant, a brand-new cab, a first-in-class safety package and much more.

In-line with market demand, all FY models are exclusively mated to the Allison HD4430 heavy-duty automatic transmission, designed for demanding on-highway and off-highway applications and known for its durability and performance.

Also found on the FV Series and common across all 2025 FY models, is a pair of the same higher-capacity Meritor MFS73 steer axle (with disc brakes), delivering an additional 500 kilograms of legal payload in accordance with recently introduced Mass Limit Allowances for vehicles meeting ADR 80/04 through the National Heavy Vehicle Regulator (NHVR). This ensures that all MY25 FY models offer more legal payload than the models they are replacing, providing a productivity opportunity to all operators

An extensive list of safety features is introduced for the first time to the FY range, matching those seen on FV and FX models launched earlier in 2025. ​ Notably, the FY models retain the excellent Lane Keeping Assist (LKA) feature with intuitive adaptive steering that has been widely acclaimed in the new FV and FX models. ​ Further highlights include Full-Speed Adaptive Cruise Control (F-ACC) and Bi-LED Headlamps with Adaptive Driving Beam (ADB).
