The IVECO Cursor 11 is a 10,857 cc, inline‑six turbo‑diesel engine produced between 2007 and 2011. It was engineered for heavy — duty commercial applications, featuring common rail direct injection, a variable geometry turbocharger (VGT), and dual overhead camshafts. Output ranged from 320 kW (435 PS) to 368 kW (500 PS), with peak torque figures between 2,000 — 2,500 Nm.
Fitted to models such as the Stralis, Trakker, and Eurocargo heavy — duty trucks, the Cursor 11 was desi…
Production years 2007–2009 meet Euro IV standards; 2010–2011 models comply with Euro V .
The IVECO Cursor 11 is a 10,857 cc inline‑six turbo‑diesel engineered for heavy‑duty trucks (2007-2011). It combines high‑pressure common‑rail injection with a single variable‑geometry turbocharger to deliver immense, sustained torque for hauling and long‑haul efficiency. Designed to meet Euro IV and Euro V standards, it prioritizes durability under continuous load.

The IVECO Cursor 11 was used across IVECO's heavy-duty platforms with longitudinal mounting. This engine received platform-specific adaptations-robust engine mounts for the Trakker off-road variant and specific cooling packages for the Stralis long-haul tractor. From 2010, models received updates for Euro V compliance, including revised EGR and SCR systems. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The Cursor 11 is renowned for its robust inline-six design and immense torque, making it a popular choice for heavy haulage. Early models (2007-2009) had cylinder head durability concerns under extreme conditions, which were largely addressed in later builds. With strict adherence to maintenance schedules, especially for coolant and oil, these engines can achieve very high mileages reliably.
The most documented issues are cylinder head cracking (early builds), EGR cooler internal leaks leading to coolant loss, AdBlue® system faults causing power derate, and turbocharger failures from poor oil maintenance. These are covered in IVECO service bulletins and relate primarily to maintenance and operating conditions.
The Cursor 11 was the flagship engine for IVECO's heavy-duty range during this period. It was fitted to the Stralis long-haul tractor, Trakker construction/off-road truck, and certain high-GVW variants of the Eurocargo ML series from approximately 2007 to 2011, powering models from 435 PS up to 500 PS.
While technically possible via ECU remapping, tuning the Cursor 11 is uncommon and generally not recommended for fleet use. The engine is already highly stressed in its stock configuration. Any power increase significantly raises thermal and mechanical loads, accelerating wear on the turbo, head, and emissions systems, potentially voiding warranties and increasing downtime.
Fuel economy varies greatly with application, load, and terrain. In a long-haul Stralis application, expect figures around 28-35 L/100km (8-6.7 mpg UK). Off-road or heavy construction use in a Trakker will see higher consumption. Efficiency is heavily dependent on driver behavior and proper vehicle maintenance, particularly tire pressure and aerodynamics.
Yes. Like virtually all modern diesel engines, the IVECO Cursor 11 is an interference engine. If the timing gears were to fail (an extremely rare event in this gear-driven design), pistons would collide with open valves, causing catastrophic internal engine damage requiring a complete rebuild or replacement.
IVECO specifies a heavy-duty diesel engine oil meeting ACEA E7 or E9 standards, typically in SAE 10W-40 or 15W-40 viscosity grades. Using the correct oil is critical for controlling soot, protecting against wear under high load, and ensuring the longevity of the turbocharger and emissions systems. Always consult the owner's manual for the specific recommendation.
