Here’s a breakdown of those Fiat Ducato models and what their engine names mean — they’re all part of the Ducato light commercial van lineup, but the numbers and names point to differences in displacement, fuel type, and emissions standard.
Engine: 2.2-liter turbo diesel (JTD = Jet Turbo Diesel — Fiat’s common-rail diesel branding).
Source: Often a PSA/Ford-derived engine in certain years, not Fiat’s own design.
Power: Typically around 100–120 hp depending on year.
Use case: Entry-level diesel option, good for lighter payloads and local delivery.
Engine: 2.3-liter turbo diesel, usually Iveco-developed (F1A engine).
Power: Around 110–150 hp depending on tuning and emissions standard.
Notes: Very common in European campervans; more torque than the 2.2 and generally more durable for heavy-duty use.
Use case: Balanced choice for mixed city and highway driving with moderate loads.
Engine: 3.0-liter turbo diesel, Iveco F1C engine.
Power: Around 157–180 hp, high torque.
Notes: Known for strong pulling power and long lifespan — used in heavier Ducato chassis and motorhomes.
Use case: Best for heavy payloads, towing, or large RV conversions.
Engine: 3.0-liter CNG (compressed natural gas) engine, factory-designed for bi-fuel or CNG-only operation.
Power: Around 136 hp (less than diesel due to CNG’s lower energy density).
Notes: Cleaner emissions, lower running costs in countries with cheap natural gas, but less range and higher curb weight due to gas tanks.
Use case: Urban deliveries in low-emission zones, fleet vehicles with access to CNG infrastructure.
Meaning: “Euro” here refers to compliance with a specific European emissions standard (e.g., Euro IV or Euro V).
Engine: 3.0-liter diesel as above, but configured to meet a given Euro emissions regulation.
Power: Usually same range (157–180 hp) but with different EGR, catalytic converters, or DPF systems depending on standard.
Meaning: Complies with Euro V emissions standard (mandatory for new vehicles in Europe from 2011 onward).
Engine: 3.0-liter Iveco diesel with upgraded emissions control — likely a DPF (diesel particulate filter) and improved EGR/NOx control.
Power: Similar output to non-Euro V versions but often slightly better fuel economy.
Notes: Euro V is stricter than Euro IV, especially on particulate matter and NOx; sometimes requires low-ash oils and more maintenance for emission systems.

In Fiat Ducato terminology, “Ducato 250” refers to the third-generation body series that was launched in 2006. Fiat internally codes its van generations with numbers like:
Ducato 244 → 2002–2006 (facelift of second generation)
Ducato 250 → 2006–2014 (third generation)
Ducato 290 → 2014–2021 (facelift of 250)
Ducato 8 → 2021–present (another major update)
So a Ducato 250 could have any of the engines you mentioned — 2.2 JTD, 2.3 JTD, 3.0 JTD, Natural Power, etc. The “250” just tells you the platform design and body style, not the displacement.
If you’re looking at a listing and it says “Fiat Ducato 250 3.0 JTD”, it means:
250 → 2006–2014 body generation
3.0 JTD → 3.0L Iveco turbo diesel engine
