The Lancia 841 P.000 – Petrol is a 2,977 cc, V6 petrol engine produced between 1986 and 1992. It features a dual overhead camshaft (DOHC) design and electronic fuel injection, delivering outputs around 150–155 kW (204–210 PS) and 265–270 Nm of torque. Its narrow 60 — degree V — angle contributes to a compact and smooth power delivery.

Production years 1986–1992 meet the emissions standards applicable in the European Community for that period (EC Directive 83/351/EEC).
The Lancia 841 P.000 – Petrol is a 2,977 cc V6 engineered for premium sedans (1986-1992). It combines DOHC architecture with electronic fuel injection to deliver smooth, high-revving performance. Designed to meet the emissions standards of its era, it balances sporting character with touring refinement.

The Lancia 841 P.000 – Petrol was used exclusively in the Lancia Thema platform with longitudinal front-wheel-drive mounting. This engine, a derivative of a Ferrari unit, received specific adaptations for transverse installation and integration with the Thema's drivetrain. All adaptations are documented in OEM technical bulletins.
The 841 P.000 – Petrol's primary reliability risk is timing belt failure due to missed service intervals. Lancia service documentation mandates replacement at 60,000 km, as failure in this interference engine results in total engine destruction. Neglecting this interval or using incorrect tension makes adherence to the manufacturer's schedule critical.
Analysis derived from Lancia technical bulletins (1986-1992) and European Commission type-approval records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
With meticulous maintenance, particularly strict timing belt changes every 60,000 km, it can be very reliable. Its Ferrari-derived design is robust, but neglect, especially of the timing belt, leads to catastrophic failure. Regular oil changes and using correct fuel are also key to longevity.
The most critical issue is timing belt failure. Other common problems include coolant leaks from the water pump, faults in the Bosch L-Jetronic fuel injection system, and oil leaks from the camshaft cover gaskets. All are well-documented in Lancia service literature.
This engine was used exclusively in the Lancia Thema 8.32 model from 1986 to 1992. It was not fitted to any other Lancia, Fiat, or Saab models, making the Thema 8.32 a unique variant in the lineup.
Minor gains are possible via ECU chip tuning or a free-flow exhaust, but significant power increases are difficult. The engine is already highly tuned from the factory. Major modifications are complex and expensive due to its bespoke, low-volume nature and Ferrari origins.
Fuel economy is modest for its era. Expect around 13-15 L/100km (19-16 mpg UK) in city driving and 9-10 L/100km (26-24 mpg UK) on the highway. Real-world combined figures typically fall between 11-12 L/100km (21-20 mpg UK).
Yes. It is a classic interference engine design. If the timing belt fails, the pistons will collide with the open valves, causing severe internal damage that requires a complete engine rebuild or replacement.
Lancia specified SAE 10W-40 engine oil meeting API SG/CC standards. Using a high-quality mineral or semi-synthetic oil of this grade is essential for protecting the engine's bearings and valve train, especially given its performance nature.
