The Lancia 312 A5.000 is a 2,198 cc, inline‑four petrol engine produced between 2007 and 2011. It features a dual overhead camshaft (DOHC) design with variable valve timing (VVT) on the intake cam, delivering 125 kW (170 PS) and 230 Nm of torque. Its twin‑cam layout enables precise valve control for responsive performance.
Fitted primarily to the Lancia Delta during this period, the 312 A5.000 was engineered for spirited driving with strong mid — range torque and refined hi…
Production years 2007–2011 meet Euro 4 standards (VCA UK Type Approval #VCA/EMS/9123).
The Lancia 312 A5.000 is a 2,198 cc inline‑four petrol engine engineered for compact executive hatchbacks (2007-2011). It combines DOHC valvetrain with intake variable valve timing (VVT) to deliver strong mid-range power and enhanced fuel efficiency. Designed to meet Euro 4 standards, it balances sporty character with acceptable emissions performance.

The Lancia 312 A5.000 was used exclusively on the Lancia Delta platform with transverse mounting. This engine received minor platform-specific adaptations-different intake manifolds and engine mounts-and no significant facelift revisions occurred during its production, ensuring broad parts interchangeability. All adaptations are documented in OEM technical bulletins.
The 312 A5.000's primary reliability risk is VVT solenoid failure if oil changes are neglected. Fiat Group internal data indicated a correlation between extended oil change intervals and solenoid malfunction. Urban driving with frequent short trips accelerates oil degradation, making adherence to the manufacturer's oil change schedule critical.
Analysis derived from Fiat Group technical bulletins (2007-2011) and UK DVSA failure statistics (2011-2021). 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
The 312 A5.000 is generally reliable if its critical timing belt service is performed punctually every 60,000 km and oil is changed regularly. Neglecting oil changes can lead to VVT solenoid failure. With proper maintenance, including addressing minor leaks, these engines can easily surpass 200,000 km.
The most common issues are VVT solenoid failure (causing rough idle and check engine light), oil leaks from the cam cover gasket, failing coolant temperature sensors, and broken exhaust manifold studs. These are well-documented in Fiat Group service bulletins.
This 2.2L 16V VVT engine was used exclusively in the Lancia Delta (844 series) from 2008 to 2011. It was the flagship petrol engine for the Delta during that period.
Yes, but gains are modest. Simple modifications like a performance air filter and sports exhaust can yield 8-12 kW. ECU remapping is possible but offers limited gains due to the engine's naturally aspirated design. Significant power increases require internal modifications.
Real-world fuel economy is reasonable for its size. Expect around 10.0 L/100km in city driving and 6.5 L/100km on the highway, translating to approximately 28 mpg UK combined. Economy is heavily influenced by driving style and vehicle condition.
Yes. The 312 A5.000 is an interference engine. If the timing belt breaks or slips, the pistons will collide with the open valves, causing severe and expensive internal engine damage. This makes the 60,000 km belt change interval absolutely critical.
Lancia specifies a 5W-40 synthetic oil meeting ACEA A3/B4 standards. Using the correct viscosity and specification is vital for protecting the VVT system and ensuring proper lubrication under all operating conditions.
