Already punching well above its weight in the Australian truck market, Isuzu’s heavy-duty range continues to defy the odds, following the highly anticipated launch of the all-new FX Series in Brisbane this week.

Sporting vastly improved powertrain technology, a first-in-class safety package as well as reborn cabin design and ergonomics, the FX line-up takes an important stride forward in its battle to join its light and medium-duty stablemates as the most popular heavy-duty truck in the country.

The 2025 FX Series has been redesigned from nose to tail, with a long list of all-new features, some clever Gross Vehicle Mass (GVM) upgrades across the line-up, not to mention some of the world’s best driveline and operational componentry.

Isuzu Australia Limited’s (IAL) Product Manager, Medium & Heavy Duty, Jeff Gibson, explained both the significance of Isuzu’s broader MY25 full-model changeover and the esteemed position held by the FX Series within it.

“The FX sits within a fascinating space in the truck market and stands alone in many respects due to the unique nature of the platform, its payload capacities and manoeuvrability,” he explained.

“The official launch of the heavy-duty FX model line-up this week has been a critical factor in this initial launch phase.

“What we’ve launched here in Brisbane is absolutely class leading on a number of fronts and will only enhance the compelling draw of the FX Series for a huge number of operators across Australia.

“We have every confidence, that when combined with the soon to be launched FY Series later this year, our heavy-duty line-up can continue to take the fight to some of the world’s largest Original Equipment Manufacturers (OEMs).”

MY25 FX Series

Engines

The FX Series, comprising of eight model variations up to 26,000 kg GVM share a six-cylinder, 259 kilowatt Isuzu powerplant known as the 6UZ1-TCC. With peak torque of 1,437 Nm from 1,400 rpm and now with ADR 80/04 compliance using the Euro VI standard on the emissions control front, this highly capable and aptly powered engine has been refined for a host of Australian applications and operational environments.

Popular amongst a diverse range of end-uses, including tilt-tray and hook-lift haulage, mining, civil and waste, the 6UZ1 powered FX range occupies a niche space at the ignitor end of Isuzu’s heavy-duty model line-up.

Transmissions

Found in the FX and heavier still FY Series, the heavy-duty Allison 4430 series 6-speed full automatic transmission is specified for its superior torque capacity and robust reliability under extreme duress.

This standout transmission, featuring Gen 6 controls, provides fluid shifting with suprising fuel efficiency suitable for various applications like agriculture, heavy construction, and long-range general freight transportation.

Safety

In-line with its broader, full model changeover, Isuzu has pushed the envelope in 2025 to design and engineer an FX Series product to bolster safety for all road users, be that the driver or other surrounding road users.

For the latest release the FX Series sees the introduction of the class-leading, dual lens camera and radar-powered Advanced Driver Assistance System (ADAS), with a string of additional safety features.

Every model across the heavy-duty line-up, benefits from a comprehensive baseline safety suite containing up to 22 active and passive systems, 10 of which are brand new to the Isuzu FX range.

The active safety system is informed by Isuzu’s ADAS camera technology, which is positioned low on the windscreen, in combination with a long-range milli-wave radar located in the centre of the bumper bar.

Highlight ADAS camera functions in the FX Series include…

Lane Departure Warning (LDW)
Lane Keep Assist (LKA),
Attention Alert System (AAS),
Traffic Movement Warning (TMW),
Traffic Sign Recognition (TSR) with Intelligent Speed Limiter (ISL),
and Adaptive Driving Beam (ADB).

Highlight ADAS camera & millimetre radar combined functions include…

Distance Warning System (DWS),
Advanced Emergency Braking (AEB),
and Full Speed Adaptive Cruise Control (FACC)

This line-up of active safety features complements existing ‘passive’ safety features found on all heavy-duty Isuzu trucks. These include SRS driver’s airbag (with passenger airbag now added for the first time), driver & outboard passenger seat belt SRS pretensioners, an ECE-R29 rated cabin and anti-intrusion bars in the doors.

Cabin styling & comfort

From the aerodynamic grille to distinctive headlamps with signature Daytime Running Lamps (DRLs) and newly engineered bumper, the prominent cabin design comes together in an assertive posture – a new look for the line-up in 2025.

Exterior design elements incorporate an LED lighting package, including Bi-LED headlights equipped with adaptive driving beam technology, as well as turn signal and the previously mentioned daytime running lamps.

Other exterior features include a new windscreen in the FX Series, providing improved ultraviolet and infrared filtering resulting in up to 99 per cent UV sun protection and 59 per cent reduction in radiated heat respectively.

After pressing a button on the driver’s door handle, access to the cabin is via a handy keyless fob system, where operators will find comfortable yet hardwearing materials and a smart and accessible cab layout.

Other convenience features include large LED overhead work light and smaller dome LED cab lights, providing exceptional interior lighting in low light.

FX Series driver seating consists of the ergonomic ISRI 6860/875 NTS2 climate seat, customisable with a massive range of controls and settings to satisfy even the fussiest of drivers, including heating and ventilation functions as standard for the first time.

The new steering wheel has integrated push-button controls for the seven-inch full colour multi-info display, volume, and phone controls, via the huge MyIsuzu Co-Pilot touchscreen multimedia system, with Apple CarPlay plus Android Auto integration, as well as a raft of control adjustments for all manner of driving conditions.

Integrated storage points can be found throughout the cabin interior and a fold-down centre seat combine to deliver smart convenience attributes that enhance the operational experience.

Coming in hot

The new FX Series is the beneficiary of just about every key advancement on offer as part of Isuzu’s global model change, from being the safest Isuzu FX ever made to a new, efficient and cleverly specified driveline set-up.

As Mr Gibson explained, the clearly defined lane the FX has managed to carve out within the Australian heavy-duty market segment is set to evolve even further in 2025 and beyond.

“With the launch of the FX and the imminent release of our twin steer FY Series following suit very shortly, we have every confidence our customers’ needs and wants in the heavy-duty space will continue be met and indeed exceeded.

“As a standalone truck builder, Isuzu continues to perform admirably against some of the world’s largest, most well-resourced automotive OEMs.

“As Isuzu’s MY25 heavy-duty offering continues to roll-out this year, it’s not impossible to think we could be knocking on the door of some these heavy hitters sooner than we think.”
