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 3…
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 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.
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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The AR 32302 is a well-regarded, robust engine when properly maintained. Its main vulnerabilities are age-related, affecting the cooling system, fuel injection sensors, and seals. Regular servicing, using correct fluids and parts, is crucial for long-term reliability and preserving its performance character.
The most frequent issues are coolant leaks from aged hoses and seals, failure of Bosch L-Jetronic sensors causing running problems, oil leaks from the valve cover and crank seals, and worn ignition components leading to misfires. These are typical for engines of this vintage.
The AR 32302 was primarily used in the Lancia Thema 8.32 from 1985 to 1994. A very limited number were also installed in special edition Lancia Delta HF 4WD models between 1987 and 1992, making it a rare and sought-after engine.
Yes, within limits. Common upgrades include performance exhausts, high-flow air filters, and ECU chip tuning to optimize the existing fuel map. Significant power gains are difficult without forced induction, as the engine is already highly tuned from the factory. Focus is often on improving drivability and throttle response.
Fuel economy is modest by modern standards. Expect around 11-13 L/100km (22-26 mpg UK) in mixed driving for a Thema 8.32. Highway cruising can yield 9-10 L/100km (28-31 mpg UK), while aggressive driving will significantly increase consumption due to its high-revving nature.
Yes. The AR 32302 is an interference engine. If the timing chain fails or jumps, the pistons will collide with the open valves, causing catastrophic internal engine damage. While chain failure is rare, it underscores the importance of overall engine health and maintenance.
Lancia originally specified a 10W-40 mineral or semi-synthetic oil. For modern use, a high-quality 10W-40 or 5W-40 synthetic oil meeting API SG/SH or higher specifications is recommended to provide better protection for the older engine design, especially during cold starts.
