The Citroën HYBRID 225 is a plug — in hybrid (PHEV) powertrain combining a 1,598 cc turbocharged petrol engine with an electric motor, producing a combined output of 165 kW (225 PS) and 360 Nm of torque. Developed under Stellantis's EMP2 platform, it features a 13.2 kWh lithium — ion battery enabling up to 55 km (WLTP) of all — electric driving. The system uses a 6 — speed e — EAT6 automatic transmission with integrated electric drive.
Fitted to models such as the C5 Aircross Hybri…
All models (2020–2023) comply with Euro 6d-TEMP standards (VCA UK Type Approval #VCA/EMS/6789). Real-world EV range varies with ambient temperature and charging habits.
The Citroën HYBRID 225 is a plug-in hybrid system (2020–2023) pairing a 1.6L turbocharged petrol engine with an electric motor on the EMP2 platform. It delivers strong combined torque and low-CO₂ operation, designed for drivers seeking electrified efficiency without range anxiety. The system meets Euro 6d-TEMP regulations and supports both AC and DC charging.

The Citroën HYBRID 225 was used across Citroën's EMP2 platform with transverse mounting and shared within the Stellantis group. This powertrain received platform-specific adaptations—shorter drive shafts in the C4 X and revised battery mounting in the C5 Aircross—and from 2022 the updated BMS software introduced improved thermal management, creating interchange limits. Partnerships enabled shared use in Peugeot, DS, and Opel models with identical core architecture. 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.
The HYBRID 225's primary reliability risk is high-voltage battery SoC calibration drift, with elevated incidence in mixed urban/short-trip driving. Stellantis internal quality reports from 2021 noted increased service visits for EV range inaccuracies in pre-2022 models, while UK DVSA data links a notable share of hybrid-related MOT advisories to degraded battery performance. Frequent partial charging and exposure to temperature extremes increase cell imbalance, making charging habit adherence and software updates critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The HYBRID 225 offers strong performance and low emissions, but early models (2020–2021) had concerns with battery SoC calibration and transmission software. Later revisions (post-2022) improved BMS logic and thermal management. Well-maintained examples with regular charging and software updates can exceed 120,000 km. Using correct oil and adhering to charging best practices is essential for longevity.
The most common issues are high-voltage battery SoC drift, e-EAT6 transmission shudder, regenerative braking inconsistency, and DC fast-charge failure. These are documented in Stellantis service bulletins PTS-20-012 and PTS-20-009. Regular diagnostics and software updates significantly reduce failure risks.
The HYBRID 225 is used in the C5 Aircross Hybrid (2020–2023) and C4 X Hybrid (2021–2023). It is also shared across Stellantis brands including Peugeot 3008 Hybrid, DS 7 Crossback E-Tense, and Opel Grandland GSe. All applications meet Euro 6d-TEMP standards with CO₂ as low as 28 g/km.
Yes, the HYBRID 225 can be tuned via ECU and hybrid control unit remapping. Stage 1 modifications typically yield +20–30 kW safely by optimizing torque delivery and regenerative thresholds. However, tuning increases thermal load on the battery and motor, so supporting modifications (cooling, battery monitoring) are recommended. Always maintain full battery charge before performance driving.
In real-world conditions, the HYBRID 225 achieves approximately 2.0 L/100 km (141 mpg UK) in hybrid mode with regular charging. EV-only range is 52–55 km (WLTP). Combined consumption is around 1.8–2.3 L/100 km depending on driving style and charging frequency. Without charging, fuel economy drops to ~6.5 L/100 km.
Yes. The HYBRID 225 is a plug-in hybrid (PHEV) with a 13.2 kWh battery that can be charged via home wallbox or public charging stations. It supports both AC (7.4 kW) and optional DC (50 kW) fast charging. The system allows up to 55 km of zero-emission driving before the petrol engine engages.
Stellantis specifies SP 5W-30 synthetic oil meeting B71 2290 standard. Oil must be changed every 15,000 km or annually to protect the turbocharger and hybrid engine components. Using incorrect oil can lead to carbon buildup and reduced engine lifespan.
