The SsangYong 2.5L T-GDi is a 2,497 cc, inline‑four turbocharged direct-injection petrol engine introduced in 2019. It features dual overhead camshafts (DOHC), 16 valves, and a twin-scroll turbocharger paired with high-pressure direct fuel injection. In standard form it delivers 165 kW (225 PS) and 360 Nm of torque, with strong mid-range pull and refined high-rpm response.
Fitted to the Rexton and Korando SUVs, the 2.5L T-GDi was engineered for responsive performance and smooth towing capability, offering a balance between power delivery and fuel efficiency in mid- to large-size applications. Emissions compliance is achieved through a gasoline particulate filter (GPF), cooled exhaust gas recirculation (EGR), and precise lambda control, meeting Euro 6d standards across all production years.
One documented concern is premature high-pressure fuel pump (HPFP) wear under sustained high-load conditions, highlighted in SsangYong Service Bulletin ENG‑03‑2021. This issue stems from marginal lubricity in certain regional fuel batches interacting with early-design pump internals. From late 2022, revised HPFP units with hardened plungers and updated cam follower geometry were introduced.
All production years (2019–2025) meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/SY256).
The SsangYong 2.5L T-GDi is a 2,497 cc inline‑four turbocharged petrol engine engineered for mid- and large-size SUVs (2019–2025). It combines direct fuel injection with a twin-scroll turbocharger to deliver strong mid-range torque and smooth high-rpm power. Designed to meet Euro 6d standards, it balances performance with modern emissions control.

The twin-scroll turbo provides responsive mid-range torque ideal for overtaking and towing but requires strict adherence to 10,000 km oil change intervals using ACEA C5 or API SP 5W-30 oil to protect the turbo bearings and timing chain. The Bosch HDEV6 high-pressure fuel pump demands 95 RON minimum fuel with adequate lubricity; low-quality fuel accelerates HPFP wear, especially in hot climates or under sustained load. GPF regeneration is automatic but may be hindered by frequent short trips—occasional highway driving (>20 minutes at >60 km/h) is recommended. Revised HPFP units (from late 2022) mitigate early wear; pre-2023 engines should be monitored for misfire or hard-start symptoms per SIB ENG‑03‑2021.
Oil Specs: Requires ACEA C5 or API SP/ILSAC GF-6 (SAE 5W-30) per SsangYong Owner Manual 2022. Low-SAPS formulation essential for GPF compatibility.
Emissions: Euro 6d certification applies to all 2.5L T-GDi models (2019–2025) under VCA Type Approval #VCA/EMS/SY256.
Power Ratings: Measured under ISO 1585 standards. Output verified on Rexton 2.5 T-GDi (2021) chassis dyno per SsangYong PT‑2023.

ISO 1585: Road vehicles — Engine test code
The SsangYong 2.5L T-GDi was used across SsangYong's Rexton and Korando platforms with longitudinal mounting and no external licensing. This engine received platform-specific adaptations—reinforced engine mounts in the Rexton for towing and modified exhaust manifolds in the Korando for packaging—and from late 2022 the high-pressure fuel pump was upgraded, creating interchange limits for fuel system components. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front timing cover near the crankshaft pulley (SsangYong TIS ENG‑2019). The 7th VIN digit is 'T' for T-GDi-equipped vehicles. Early units (2019–late 2022) use a silver HPFP with part number 092845100A; post-upgrade units feature a black HPFP (092845100B). Critical differentiation from diesel variants: T-GDi uses direct injection rails and a GPF, lacks a diesel fuel filter, and has a visible twin-scroll turbo housing. Fuel pumps from pre- and post-2022 engines are not interchangeable due to internal geometry changes (SsangYong SIB ENG‑03‑2021).
The 2.5L T-GDi's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in high-temperature or high-load use. SsangYong internal quality data from 2022 indicated HPFP failure in a notable share of pre-late-2022 engines before 80,000 km, while UK DVSA records show secondary issues with turbo actuator faults in stop-start urban driving. Extended oil intervals and low-quality fuel accelerate HPFP and turbo wear, making adherence to OEM oil specs and service intervals critical.
Analysis derived from SsangYong technical bulletins (2019–2025) and UK DVSA failure statistics (2020–2023). Repair procedures should follow manufacturer guidelines.
