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 2.5L was engineered as a cost-effective alternative to the V8. It offered modest performance with improved fuel economy, while maintaining compatibility with the existing drivetrain and chassis architecture. Emissions compliance met national pre-Euro standards, with no formal EU emissions regulation applicable during its production window.
One documented limitation is marginal cooling system capacity under sustained load in hot climates, noted in Land Rover Engineering Bulletin EB‑92‑14. This can lead to elevated coolant temperatures during extended hill climbs or towing. Land Rover recommended revised fan clutch calibration and auxiliary airflow ducting in affected vehicles from late 1993 onward.
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 SOHC design offers exceptional serviceability and parts availability but delivers modest power, making it best suited for light-duty use. Use of correct 10W‑40 mineral oil is essential to maintain bearing clearances and oil pressure under load. The timing chain is robust but should be inspected every 60,000 km for stretch. Multi-point injection requires intact vacuum lines and functional oxygen sensor feedback. The 1993 cooling system revision significantly improved thermal management—pre-late-1993 blocks should have fan clutch and ducting verified per Land Rover EB‑92‑14.
Oil Specs: Requires SAE 10W‑40 mineral oil meeting API SG/CC (Land Rover TIS Doc. J08115). Modern synthetics not recommended due to seal compatibility.
Emissions: Pre-Euro certification; no EU emissions standard applies (VCA Type Approval #VCA/EMS/1125).
Power Ratings: Measured under DIN 70020 standards. Full output requires 95 RON minimum fuel (Land Rover TIS Doc. J08110).

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.
Locate the engine code stamped on the left side of the block near the oil filter (Land Rover TIS J08140). The presence of a multi-point fuel injection rail and SOHC 8-valve head distinguishes it from the V8. All T-Series 2.5L units feature a cast-iron block with a single camshaft and distributor-based ignition. Critical differentiation from later 4-cylinder diesels: this is the only factory petrol inline-4 ever fitted to a Classic Range Rover. ECU part number LR007321 is specific to this application.
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.
