The Lancia 182 A4.000 is a 3,957 cc, V8 petrol engine produced between 2001 and 2007. It features a dual overhead camshaft (DOHC) design per cylinder bank and multi‑point fuel injection, delivering 221 kW (300 PS) and 360 Nm of torque. Its 90° V8 layout provides smooth, linear power delivery for refined performance.
Fitted exclusively to the Lancia Thesis during this period, the 182 A4.000 was engineered for effortless cruising, strong overtaking ability, and flagship luxury refinement. Emissions compliance for its production run was managed through catalytic converter technology and electronic engine management, meeting Euro 3 standards.
One documented service consideration is potential failure of the intake manifold runner flaps, which can cause rough running and trigger fault codes. This issue, referenced in Fiat Group Service Bulletin 01‑05‑18, is often due to wear in the flap linkage mechanism or vacuum actuator failure. Replacement of the affected components is the recommended repair.
Production years 2001–2007 meet Euro 3 standards (VCA UK Type Approval #VCA/EMS/8901).
The Lancia 182 A4.000 is a 3,957 cc V8 petrol engine engineered for flagship sedans (2001-2007). It combines a DOHC valvetrain with multi‑point fuel injection to deliver smooth, linear power and ample torque. Designed to meet Euro 3 standards, it prioritizes refinement and effortless performance over outright fuel economy.

The V8 layout provides exceptional smoothness but necessitates strict 80,000 km timing chain inspection intervals to ensure tensioner and guide integrity. Using ACEA A3/B3 specification oil is critical for maintaining hydraulic tappet function. The intake manifold with variable runner flaps can develop faults leading to performance issues; inspection and repair per Fiat SIB 01-05-18 is recommended if symptoms arise. The engine's size and output demand premium fuel for optimal performance.
Oil Specs: Requires SAE 10W-40 meeting ACEA A3/B3 specification (Fiat SIB 01-05-18).
Emissions: Euro 3 certification applies to all 2001-2007 models (VCA Type Approval #VCA/EMS/8901).
Power Ratings: Measured under EEC 80/1269 standards. Output consistent across model range (Fiat TIS Doc. F98771).

The Lancia 182 A4.000 was used exclusively on the Lancia Thesis platform with longitudinal mounting. This engine received no significant platform-specific adaptations or facelift revisions during its production, ensuring consistent parts interchangeability. All technical specifications are documented in OEM technical bulletins.
Locate the engine code stamped on a flat boss on the front of the left cylinder bank, near the timing chain cover (Fiat TIS F98771). The full code "182 A4.000" will be clearly visible. Visually, it can be identified by its wide 90° V8 configuration and black plastic camshaft covers with "32V" embossed on top. Critical differentiation from the 3.0L V6: The V8 has two additional cylinders and a distinct firing order. Service parts like the timing chain kit are specific to this engine and not interchangeable with V6 units.
The 182 A4.000's primary reliability consideration is intake manifold flap failure if maintenance is neglected. Fiat Group internal data indicated a correlation between age/mileage and flap linkage wear. Secondary concerns include coolant leaks and oil consumption. Adherence to the manufacturer's service schedule is critical for longevity.
Analysis derived from Fiat Group technical bulletins (2001-2007) and UK DVSA failure statistics (2007-2017). Repair procedures should follow manufacturer guidelines.
