Isuzu’s popular MY25 FY Series line-up is officially on sale across Australia, consisting of six model variants under the FYH and FYJ badges.
Part of the brand’s second phase model roll-out, the new FY release rounds-out Isuzu’s heavy-duty offering, at up to 32,000-kilogram Gross Vehicle Mass (GVM).
With a range of wheelbase options, the versatile 8×4 FY line-up features a new Euro VI based powerplant meeting ADR80/04, a brand-new cab, a first-in-class safety package and more.
“Going back over a decade since its inception in 2012, the FY Series has gained a loyal following amongst a range of Australian industry, from concrete mixing to waste, utilities and excavation,” said Isuzu Australia Limited’s (IAL) Head of Sales, Craig White.
“It’s carved out quite a niche for itself over the years and continues to perform admirably against some of its heavyweight brand competitors in that market segment,” he added.
“With this release, we can say unequivocally that the FY Series offers a highly competitive spec at its price-point and presents a compelling value-proposition for heavy-duty operators.”
With the FYH, there’s two variants available in both 5.8 and 6.0 metre wheelbases– the FYH 320-355 AT R58 (5770 mm) and FYH 320-355 AT R60 (6010 mm).
There are also four FYJ models in the group which include several wheelbase options, from a shorter 5080 mm variant, up-to the extra-long wheelbase FYJ 320-355 AT R67 model at 6700 mm.
Suitable for a range of tasks, all models within the FY lineup share a GVM of 32,000kg. Also found on the FV Series and common across all 2025 FY models, are the higher-capacity Meritor MFS73 steer axle/s (with EBS disc brakes), delivering to an additional 500 kilograms of legal capacity in accordance with recently introduced ADR 80/04 (Euro VI) emissions mass limits increase.
Across the FY range is Isuzu’s 6-cylinder, direct injection 6UZ1-TCC powerplant which has evolved in 2025, now with a new power and torque delivery of 259 kW at 2000 rpm and torque rating of 1437 Nm at 1400 rpm.
This new Euro-VI 6UZ1 engine variant also has an advanced emission control system, deploying Exhaust Gas Recirculation (EGR), a Diesel Particulate Diffuser (DPD and Selective Catalytic Reduction (SCR). All of this is combined to meet the new mandatory ADR80/04 emission levels now required in Australia.
In-line with market demand, all FY models are exclusively mated to the Allison HD4430 heavy-duty automatic transmission.
Featuring a one-stage, three-element, polyphase torque converter for smooth power transfer, the HD4430 uses 6th generation electronic controls for adaptive shifting, superior acceleration, startability and vehicle control.
Combined with the new MY25 ISUZU electrical architecture and communication system, the engine and transmission work seamlessly to interface the powertrain and provide an efficient drive and safe retardation control when needed.
The FY Series offers a complete safety ecosystem, integrating up to 12 active and passive systems for comprehensive driver confidence and occupant protection.
This is made possible thanks to Isuzu’s enhanced Advanced Driver Assistance System – ADAS, which pairs a low-mounted windscreen camera with a bumper-integrated long-range radar. This powerful combination delivers a suite of intelligent features.
The camera independently handles functions like Lane Keep Assist and Adaptive Driving Beam, while the amalgamated dual optical sensor system data enables life-saving technologies like Advanced Emergency Braking and Full-speed Adaptive Cruise Control.
This proactive safety net is complemented by robust passive protection, including multiple SRS airbags, a crash-rated cab, and reinforced door bars, ensuring protection in just about every scenario.
“We have every confidence our customers’ needs and wants in the heavy-duty space will continue be met and indeed exceeded with this latest release,” added White.
