Isuzu Australia Limited (IAL) is peeling back the curtain on some key technology built into its newly-announced model line-up, which will be going on sale throughout 2025.
Isuzu has utilised a specific design approach to develop its new truck model range – known as the Isuzu Modular Architecture and Component Standard (I-MACS) – which has enabled a range of enhancements.
According to Simon Humphries, the Australian arm’s Head of Product Management & Commercial Vehicles Chief Engineer, the I-MACS approach strikes a balance between the designs that customers have been asking for and the designs that will be critical to the new era of transport.
“This approach allows the design, development and combination of various common components, parts and devices to be applied in light of future tech advancement and the expression of vehicle types,” he said.
“Hard-wired into this new model range is an improved understanding of the linkage between vehicle components and the notion of interchanging or relocating components – all making it possible to adapt to the future while remaining compatible with legacy models.”
Powering this innovation is the rollout of an all-new global wiring harness system intended to have a more ‘far-reaching’ influence on the vehicle’s operation, regardless of the powertrain applied and the market in question.
Humphries also discussed how improvements to the flow of energy and information within a vehicle’s electrical architecture can have major impacts to its primary functions.
“With the level and sophistication of technology now found in modern cars and trucks, particularly in the area of safety innovation, the need for more robust communications systems simply translates to faster, more reliable operation of a range of active and passive functions,” he noted.
Other key technological developments in Isuzu’s 2025 range has seen a departure from traditional intra-vehicle communications, instead moving towards a new lightning-fast digital messaging system, ensuring more responsive equipment.
“Under the banner of the global I-MACS approach, we’ve transitioned to full CAN (Controller Area Network) bus communications, which connects multiple electrical devices or modules together,” Humphries said.
“This means there’s now faster, more reliable decision-making between critical modules within the vehicle, such as braking, steering and sensory reaction times between the truck and ancillary body equipment.”
Humphries also discussed the new Isuzu generation’s compliance with the United Nations Economic Commission for Europe’s regulation 155 (UNECER155), reflecting the group’s commitment to addressing cyber security risks across an increasingly advanced mobility ecosystem.
“These recent regulations are part of a global push to protect against cyber security threats,” he said.
“As our products become increasingly connected, a more standardised and unified approach is needed.”
In response to this, Isuzu has introduced a new gateway central controller unit that separates different module networks to produce more secure communication between critical functions of the truck.
“This is an exclusive gateway for Isuzu products, helping to protect the integrity of a range of key systems such as our advanced driver assistance system,” Humphries added.
“There’s a huge amount of data floating around a modern truck, so when we think about some of the autonomous safety features that might save our lives one day, the ultimate goal is to have those systems completely locked down and inaccessible to cyber threats.”
Backed by Isuzu’s desire to consistently deliver global mobility solutions, Australian operators stand to greatly benefit from these features.
“These peripheral smarts are paving the way for safer, more efficient and better-suited products for Australian operators,” Humphries said.
“This is about seizing an opportunity such as an entirely new model launch and building in critical improvements that will, without a doubt, see out the lifespan od a particular model or product.”
