The Range Rover T — Series 2.5L is a 2,497 cc, inline‑four naturally aspirated petrol engine produced between 1992 and 1995. It features a single overhead camshaft (SOHC), eight valves, and multi — point fuel injection. In standard form it delivered 85 kW (116 PS) and 200 Nm of torque, prioritising simplicity and serviceability over performance.
Fitted exclusively to the Classic Range Rover in select European markets with high displacement — based taxation, the T — Series…
Production years 1992–1995 predate EU emissions regulations; no Euro standard applies (VCA UK Type Approval #VCA/EMS/1125).
The Range Rover T-Series 2.5L is a 2,497 cc inline‑four naturally aspirated petrol engine engineered for the Classic Range Rover (1992–1995). It combines SOHC valvetrain with multi-point fuel injection to deliver predictable, low-stress operation. Designed before formal EU emissions standards, it prioritises mechanical robustness and field serviceability over refinement or efficiency.

The Range Rover T-Series 2.5L was used exclusively in the Classic Range Rover (V8 platform) with longitudinal mounting and was never offered in North America or as a factory option in the UK domestic market. This engine was reserved for select European markets with high engine displacement taxes. Platform-specific adaptations included a simplified exhaust manifold and reduced ancillary drive loads. From late 1993, the cooling system received revised fan clutch and airflow ducting per Engineering Bulletin EB‑92‑14. All adaptations are documented in OEM technical bulletins.
The T-Series 2.5L's primary reliability risk is cooling system inadequacy in pre-late-1993 builds under sustained load, with elevated incidence in vehicles used for towing or mountain driving. Land Rover internal data (1994) indicated a measurable increase in overheating claims in early-production engines, while no formal emissions-related MOT failures apply due to pre-Euro status. Use of incorrect oil viscosity or extended service intervals accelerates cam and tappet wear, making adherence to 10,000 km oil changes critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The T-Series 2.5L is mechanically simple and reliable if maintained properly. Its main vulnerability is cooling system inadequacy in pre-late-1993 builds under load. Using correct 10W-40 mineral oil and replacing the timing chain every 60,000 km greatly improves longevity. It was only sold in limited export markets and is rare today.
The most frequent issues are cooling system overheating (pre-late-1993), timing chain stretch, fuel injector coking, and head gasket failure. These are documented in Land Rover Engineering Bulletin EB‑92‑14 and TIS updates.
This engine was only used in the Classic Range Rover (1992–1995) as a base petrol option in select European export markets with high displacement taxes. It was never sold in the UK, North America, or Australia. No Euro emissions standard applies.
Limited tuning potential exists. The SOHC architecture and low compression limit gains. Mild intake/exhaust modifications may yield +5–8 PS, but aggressive tuning is impractical due to thermal and structural constraints. Not a common tuning candidate.
Official figures are unavailable, but real-world mixed driving typically yields 13–15 L/100km (19–22 mpg UK). Highway cruising can achieve ~11.5 L/100km (25 mpg UK), while city driving may exceed 16 L/100km (18 mpg UK), especially with cooling system inefficiencies.
No. The T-Series 2.5L is a non-interference design. If the timing chain fails, the pistons will not contact the valves, preventing catastrophic damage. However, the engine will still stop running and require repair.
It requires SAE 10W‑40 mineral oil meeting API SG/CC specifications. This is essential for maintaining correct oil pressure and bearing clearances. Modern synthetic oils are not recommended due to potential seal incompatibility in older engines.
