The Lancia AR 32302 is a 1,995 cc, inline‑four petrol engine produced between 1985 and 1994. It features a twin‑cam (DOHC) cylinder head and electronic fuel injection, delivering a balance of performance and refinement for its era. Peak output varied by application but typically ranged from 103 kW (140 PS) to 118 kW (160 PS), with torque figures around 186 Nm, providing responsive mid-range power.
Fitted primarily to the Lancia Thema 8.32 and select Delta HF models, the AR 32302 was engineered for a sporty yet refined driving character. It offered brisk acceleration and a high-revving nature, distinguishing it from contemporary turbocharged units. Emissions compliance for its production period was managed through its electronic fuel injection system, meeting prevailing Euro 1 standards.
One documented engineering focus was managing the thermal load on the cylinder head, particularly in sustained high-RPM use. Service documentation from the period highlights the importance of maintaining the cooling system's integrity. The engine was eventually superseded by more modern, emissions-focused powertrains as regulations evolved.
Production years 1985–1994 meet Euro 1 standards as per applicable EU regulations at the time of manufacture (EU Directive 88/77/EEC).
The Lancia AR 32302 is a 1,995 cc inline‑four petrol engine engineered for executive and performance sedans (1985-1994). It combines a DOHC 16-valve cylinder head with electronic fuel injection to deliver a high-revving, responsive character. Designed to meet Euro 1 emissions standards, it prioritized performance within the regulatory framework of its era.

The naturally aspirated design provides linear power delivery but requires higher RPMs for peak performance, impacting fuel economy under spirited driving. Regular coolant system maintenance is critical to prevent overheating, especially given the engine's performance orientation. Using the specified 10W-40 oil helps protect the older valvetrain design. The Bosch L-Jetronic system is robust but sensitive to fuel quality and requires precise sensor calibration for optimal running.
Oil Specs: Requires SAE 10W-40 specification (Lancia Owner's Manual). Modern equivalents meeting API SG/SH are acceptable.
Emissions: Euro 1 certification applies to all production years (1985-1994) under EU Directive 88/77/EEC.
Power Ratings: Measured under SAE J1349 standards. Output varies by model year and specific ECU mapping (Lancia Group PT-1990).

The Lancia AR 32302 was used exclusively in Lancia's Thema platform with longitudinal mounting. This engine received specific adaptations for the high-performance 8.32 variant, including a unique intake manifold and ECU mapping. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the block near the cylinder head's front face, adjacent to the timing cover. The full designation "AR 32302" should be clearly visible. The 8.32 variant is further identified by its distinctive red valve cover and "8.32" badging on the car. Critical differentiation from other AR engines: The 32302 has a unique intake manifold casting and specific Bosch ECU part numbers (e.g., 0 280 000 123). Service parts, particularly gaskets and sensors, are specific to this engine code and not interchangeable with other AR series engines without verification.
The AR 32302's primary long-term consideration is maintaining the integrity of its cooling system and fuel injection components. While generally robust, age-related wear on rubber hoses, seals, and the Bosch L-Jetronic sensors can lead to performance issues. Regular preventative maintenance is key to preserving its high-revving character.
