The developments on the New Stralis focused on energy management to achieve the significant reduction in TCO in every mission and every type of route.
The new engines have been re-engineered to reduce friction and a new anti-idling function automatically turns off the engine after a pre-set period of time when the vehicle is parked, improving the use of energy.
The Smart Auxiliaries on the New Stralis 480XP and 570XM prevent energy losses when they are not in use: they include the clutch compressor and air processing unit, energy-recovery alternator with intelligent battery monitoring and a variable-flow steering pump.

The Smart EGR system featured on the New Stralis 480XP and 570XM is an innovative solution that works in combination with Iveco’s patented HI-SCR after-treatment system to optimise combustion, bringing a significant fuel-saving benefit on long-haul routes. It harnesses a small amount of exhaust gas re-circulation (just 8%) to allow an earlier start of injection, reducing fuel consumption while the high 97% tailpipe NOx conversion, which is ensured by the HI-SCR system, is maintained. This revolutionary smart solution has all the advantages of the HI-SCR-only system: no impact on radiator size, no extra maintenance, no weight increase, no parked regeneration and the longest service intervals, resulting in a further reduction in fuel and TCO. With this solution, Iveco and its engine development partner FPT Industrial once again prove their long-established leadership in fuel efficiency technology.
The HI-CRUISE GPS predictive driving system, based on state-of-the-art mapping technology, compares geo-localisation with road topography and accordingly adopts predictive strategies in acceleration, deceleration and gear shifting. This feature simplifies the driver’s job, allowing them to focus on safety instead of road routine, and enhances their comfort with a smooth drive. In addition, it delivers substantial fuel savings also with low-skilled drivers.
The new triple “A” eco-tyres developed by Michelin minimise rolling resistance, achieving significant fuel savings up to 1.5% on average during first life. This results in an environmental benefits of 1.33 kg less CO2 every 100 km, which adds up to over 3.7 tons during the vehicle’s first life. These savings are achieved while maintaining the same grip, robustness and durability.
The all-new rear axle with single reduction improves gear geometry, friction and optimises fuel consumption.
These new features result in a double-digit improvement in fuel efficiency compared to the previous model.
In addition new technologies, features and services have been added to reduce TCO even further.
The new-generation, 12-speed HI-TRONIX automated transmission, developed in collaboration with ZF, is at the forefront of technological advancement in its category and dramatically improves durability and reduces costs. The HI-TRONIX reduces shifting time by 10%, it is designed for almost twice the gearshifts of the previous generation, it can improve durability by up to 1.6 million kilometers, and it abates acoustic emissions by 6db – ideal for quiet night missions – all this while providing best-in-class torque-to-mass ratio, ratio spread and efficiency. In addition, its modular, service-friendly design reduces maintenance and simplifies repairs, with consequent savings. It also offers additional functionalities, such as maneuvering mode (creep) for low-speed operation, working like a torque-converter transmission, rocking function to recover grip on low-adherence surfaces, 4 reverse gears and a new range of PTOs.
The rear suspension has been completely redesigned to make it more mass-efficient and durable, resulting in a lighter suspension while maintaining performance; this translates into 45 kilograms more payload. Higher resistance to corrosion, achieved with surface treatment of all key metallic components, contributes to lower maintenance costs.
The new electric and electronic architecture adopted on New Stralis and New Stralis XP represents a technological breakthrough, and an enabler of further innovation. Based on the MUX concept, it sees on-board electronic units communicate through two physical wires using a common protocol.
The new HI-MUX - the Stralis evolution of this concept - has been implemented through the re-design the whole distribution layout and some of its components. Its architecture is modular, split into two for improved flexibility and serviceability and integrated in a new layout with pneumatic, fuel and AdBlue ducts. HI-MUX allows the development of a detailed design solution for any specific truck configuration, while reducing the number of components and their assembling complexity.
The outstanding reliability and durability of the New Stralis also results in lower Maintenance and Repairs costs: 5% less than a current model with a standard 3-year contract and 8% with a 4-year one, improving on a cost that was already very competitive and cutting further overall TCO.
