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.

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 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.
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.
Analysis derived from Alfa Romeo technical bulletins (2015–2020) and UK DVSA failure statistics (2018–2023). 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 940 A2.000 offers balanced performance and efficiency, with fewer thermal issues than turbocharged variants. Later models (post-2017) with updated PCV routing improved intake cleanliness. Consistent use of correct oil (5W-30 C2/C3, Fiat 9.55535-S2) and adherence to maintenance intervals are essential for long-term reliability.
Primary issues include intake valve coking from direct injection, MultiAir actuator degradation due to oil contamination, and throttle body carbon buildup. Secondary concerns involve oil leaks from valve cover gaskets and cam timing correlation faults. These are documented in Alfa Romeo service bulletins and technical advisories.
This 1.8L naturally aspirated petrol engine was used exclusively in the Giulietta (940, 2015–2020), producing 120–150 PS. All models meet Euro 6b emissions standards and feature standard suspension and transmission tuning for everyday driving.
Yes. The 940 A2.000 responds well to ECU remapping, with stage 1 tunes typically adding +15–25 kW. Stock internals support moderate increases, but higher power levels require upgraded intake, exhaust, and engine management. Tuning should preserve OEM safety margins and use premium fuel to avoid knock.
In real-world driving, expect 7.8–9.2 L/100km (31–36 mpg UK) in mixed conditions. Highway efficiency improves to ~6.7 L/100km (~42 mpg UK). Base trims consume slightly less. Aggressive driving and short trips reduce economy significantly due to emissions system demands.
Yes. The 940 A2.000 is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, resulting in severe internal damage. Regular inspection of the chain tensioner and guides is critical to prevent catastrophic failure.
Alfa Romeo specifies SAE 5W-30 C2/C3 oil meeting Fiat 9.55535-S2 specification. Oil must be changed every 15,000 km or annually. Using correct oil is vital for MultiAir system longevity, valve train lubrication, and preventing sludge buildup in high-temperature zones.
