The IVECO Cursor 12 is an 11,100 cc, inline‑six turbo‑diesel engine produced between 2006 and 2016. It features common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts. In standard form it delivered 331 kW (450 PS), with higher — output versions reaching 412 kW (560 PS) and torque figures between 2,000 — 2,500 Nm. The VGT enables immense low — rpm torque for heavy — haul drivability.
Fitted to models such as the Stralis, Trakker, and…
Production years 2006–2010 meet Euro 4 standards; 2011–2016 models meet Euro 5 compliance depending on market (IVECO Type Approval #IT/EMS/9876).
The IVECO Cursor 12 is an 11,100 cc inline‑six turbo‑diesel engineered for heavy-duty trucks and long-haul applications (2006-2016). It combines common‑rail direct injection with a single variable‑geometry turbocharger to deliver immense torque for heavy loads and sustained high-speed cruising. Designed to meet Euro 4 and Euro 5 standards, it prioritizes commercial durability with operational efficiency.

The IVECO Cursor 12 was used across IVECO's heavy-duty platforms with longitudinal mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Trakker and modified cooling packages in the Stralis-and from 2011 the facelifted S-Way models adopted revised SCR dosing units for Euro 5 compliance, creating minor parts interchange limits. All adaptations are documented in OEM technical bulletins.
The Cursor 12's primary reliability risk is EGR cooler failure, with elevated incidence in vehicles operating under sustained high load. IVECO internal service data from 2013 indicated a significant portion of pre-2011 engines required cooler replacement before 500,000 km, while fleet operator reports link a notable share of roadside breakdowns to coolant system faults. Extended service intervals and poor coolant quality make strict adherence to coolant maintenance and quality critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The Cursor 12 is a highly durable engine designed for million-kilometer service lives in heavy-duty applications. Early models (2006-2010) had notable EGR cooler reliability concerns. Later revisions (post-2011) significantly improved cooler durability. With strict adherence to coolant, oil, and AdBlue maintenance schedules, these engines are exceptionally reliable for commercial fleets.
The most frequent issues are EGR cooler failures, turbocharger bearing wear, AdBlue injector clogging, and high-pressure fuel pump wear. These are well-documented in IVECO service bulletins and are often linked to maintenance intervals and fluid quality.
The Cursor 12 engine was used in the IVECO Stralis (AS440, AS560), Trakker (AD380, AD440), and S-Way (AS440S, AS560S) models from 2006 to 2016. It was the flagship 11.1L diesel for IVECO's heavy-duty range during this period.
Yes, the Cursor 12 has significant tuning potential. ECU remaps can safely increase power by 30-50 kW and torque by 200-400 Nm on stock internals for improved hill-climbing ability. However, aggressive tuning increases stress on the turbo, cooling, and drivetrain, so enhanced maintenance and component monitoring are essential.
Fuel economy varies greatly by vehicle weight, aerodynamics, and duty cycle. In a Stralis AS440 long-haul tractor, expect ~32-38 L/100km on highways. In a heavier Trakker AD440 for construction, figures can be 45-55 L/100km. Real-world economy is heavily dependent on load, terrain, and driver behavior.
Yes. The Cursor 12 is an interference engine. If the timing gears were to fail (though highly unlikely due to their robust design), pistons would collide with open valves, causing catastrophic engine damage. This underscores the importance of overall engine health.
IVECO specifies a 10W-40 synthetic or semi-synthetic oil meeting API CI-4 (or ACEA E7) standards. Using the correct oil is vital for protecting against soot-related wear and maintaining the longevity of the turbocharger and fuel system components under heavy loads.
