The Alfa Romeo 940 A2.000 is a 1,750 cc, inline-four petrol engine produced between 2015 and 2020. It forms part of the Tigershark engine family, featuring MultiAir II variable valve timing and direct fuel injection for improved efficiency and responsiveness. Delivering 88–110 kW (120–150 PS) and up to 240 Nm of torque, it provides strong low-end performance ideal for urban driving dynamics.
Fitted to the Giulietta (940), the 940 A2.000 was engineered for balanced everyday performance with a focus on drivability and fuel economy. Emissions compliance is achieved through integrated exhaust manifolds, cooled EGR, and a close-coupled three-way catalytic converter, enabling Euro 6b compliance across its production run.
One documented concern involves premature intake manifold carbon buildup observed in stop-start urban driving, highlighted in Alfa Romeo Technical Bulletin 42/2017. The issue was linked to oil vapour ingress via the crankcase ventilation system under frequent cold-start conditions. From 2017 onward, revised PCV routing and updated ECU adaptations were implemented to mitigate the risk.
All production years 2015–2020 meet Euro 6b emissions standards (VCA UK Type Approval #VCA/EMS/5681).
The Alfa Romeo 940 A2.000 is a 1,750 cc inline-four petrol engine engineered for compact performance models (2015–2020). It combines MultiAir II variable valve control with naturally aspirated design to deliver responsive throttle characteristics and linear power delivery. Designed to meet Euro 6b standards, it balances everyday usability with Alfa Romeo’s signature driving character.

The MultiAir II system enables sharp throttle response and strong low-end torque, but requires strict adherence to 15,000 km oil change intervals using Fiat 9.55535-S2 specification oil to prevent hydraulic valve actuator degradation. Direct injection contributes to intake valve coking, necessitating periodic induction cleaning. Post-2017 models benefit from revised PCV routing and updated ECU mappings per Technical Bulletin 42/2017, reducing carbon buildup risk. Emissions systems require periodic DTC monitoring to prevent catalyst efficiency faults. No turbocharger reduces thermal stress but does not eliminate the need for proper warm-up procedures after cold starts.
Oil Specs: Requires SAE 5W-30 C2/C3 meeting Fiat 9.55535-S2 specification (Alfa Romeo SIB 42/2017).
Emissions: Euro 6b certification applies to all 940 A2.000 models (2015–2020) (VCA Type Approval #VCA/EMS/5681).
Power Ratings: Measured under ECE R85 standards. 110 kW output requires premium 95 RON fuel (Alfa Romeo TIS Doc. A940PWR).

The Alfa Romeo 940 A2.000 was used exclusively in the Alfa Romeo 940 (Giulietta) platform with transverse mounting. This engine received platform-specific tuning—optimized intake manifold length and revised throttle mapping—and from 2017, updated crankcase ventilation routing per Technical Bulletin 42/2017, creating service part interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block near the starter motor (Alfa Romeo TIS A940ID1). The 8th VIN digit indicates engine type ('A' for 940 series). All units have a silver valve cover with a red Alfa Romeo logo and no turbocharger. Critical differentiation from 939 A5.000: The 940 A2.000 is naturally aspirated with a simpler intake system. Service parts require model-year verification—PCV valves and intake manifolds before 2017 are not compatible with post-update revisions per Technical Bulletin 42/2017.
The 940 A2.000's primary reliability risk is intake valve coking under short-trip use, with elevated incidence in city-driven vehicles. Internal FCA quality reports from 2018 noted increased DTCs related to cam timing correlation in pre-2017 models, while UK DVSA records show a moderate rate of emissions-related faults linked to catalyst efficiency. Frequent stop-start driving and poor oil maintenance amplify stress, making oil quality and driving habit adherence critical.
