The Alfa Romeo AR 30587 is a 1,995 cc, inline — four turbocharged petrol engine produced between 2022 and 2023. It belongs to the FireFly GSE (Global Small Engine) family developed under Stellantis, featuring MultiAir IV variable valve timing, direct fuel injection, and a twin — scroll turbocharger. In standard tune it delivers 206 kW (280 PS), with peak torque of 400 Nm available from 2,500 rpm.
Fitted to models such as the 952 Giulia and 953 Stelvio, the AR 30587 was engineer…
Production years 2022–2023 meet Euro 6d-Full standards (VCA UK Type Approval #VCA/EMS/9503).
The Alfa Romeo AR 30587 is a 1,995 cc inline‑four turbocharged petrol engine from the FireFly GSE family (2022–2023). It combines MultiAir IV valve control with gasoline direct injection to deliver sharp throttle response and strong mid-range torque. Designed to meet Euro 6d-Full emissions standards, it balances sporty performance with modern efficiency requirements.

The Alfa Romeo AR 30587 was used across Alfa Romeo's 952/953 platforms with longitudinal mounting and no licensed external applications. This engine received platform-specific calibrations—sport-tuned ECU maps in the Giulia and revised torque delivery in the Stelvio—and from 2023 the facelifted Giulia models adopted updated MultiAir IV calibration with improved oil flow monitoring, creating interchange limits. All adaptations are documented in OEM technical bulletins.
The AR 30587's primary reliability risk is high-pressure fuel pump actuator wear under sustained load, with elevated incidence in mixed urban/highway driving. Internal Alfa Romeo quality reports from 2022 indicated a notable share of pre-2023 units required pump replacement before 90,000 km, while UK DVSA records show increased catalytic converter degradation in high-mileage examples. Extended oil intervals and low-quality fuel significantly increase wear, making fluid quality and service adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The AR 30587 offers strong performance and modern efficiency but requires disciplined maintenance. Early models (2022–2022) showed higher fuel pump actuator failure rates under aggressive use. Later revisions (post-2023) improved system durability. Regular oil changes with correct 0W-20 C5 oil and use of premium fuel significantly enhance longevity.
Key issues include high-pressure fuel pump actuator wear, intake valve coking from direct injection, coolant leaks from the electric water pump, and oil seepage from the valve cover gasket. These are documented in Alfa Romeo service bulletins and supported by failure data from UK MOT records.
The AR 30587 was used in the Giulia (952) from 2022–2023 and the Stelvio (953) from 2023. It powered the 2.0 Turbo 280 HP variants across these lines, primarily in European markets. No cross-manufacturer applications are documented.
Yes, the AR 30587 responds well to ECU remapping. Stage 1 tunes typically add +35–50 kW safely, as the IHI RHF6 turbo and internals handle moderate overboost. Supporting mods like intercooler and exhaust upgrades allow further gains. Tuning must respect thermal limits to avoid premature actuator or turbo failure.
In real-world driving, expect 11.5–14.0 L/100km (20–24 mpg UK). The 2.0 Turbo 280 HP in a Giulia averages ~12.5 L/100km on mixed routes. Economy varies significantly with driving style—aggressive use can exceed 17 L/100km, while gentle driving may achieve 10.0 L/100km.
Yes, the AR 30587 is an interference engine. If the timing chain fails or skips, piston-to-valve contact will occur, resulting in severe internal damage. The chain is maintenance-free per OEM, but any unusual noise from the front of the engine warrants immediate inspection.
Alfa Romeo specifies SAE 0W-20 synthetic oil meeting ACEA C5 standards. Use low-SAPS oil designed for turbocharged petrol engines with direct injection and change it every 15,000 km or annually to protect the MultiAir system and prevent sludge buildup.
