The Alfa Romeo AR 30586 is a 1,995 cc, inline — four turbocharged petrol engine produced between 2018 and 2023. It was developed as a high — performance, direct — injection powerplant for Alfa Romeo's premium performance models, featuring dual overhead camshafts (DOHC), variable valve timing (VVT), and gasoline direct injection (GDI). In standard tune it delivered 206 kW (280 PS), with peak torque of 400 Nm available at 2,500–5,000 rpm.
Fitted to models such as the Giulia Q…
Production years 2018–2023 meet Euro 6d-Full standards .
The Alfa Romeo AR 30586 is a 1,995 cc inline-four turbocharged petrol engine engineered for high-performance applications (2018–2023). It combines gasoline direct injection with twin-scroll turbocharging to deliver rapid throttle response and strong mid-range torque. Designed to meet Euro 6d-Full emissions standards, it balances track capability with road legality.

The Alfa Romeo AR 30586 was used across Alfa Romeo's 952/960 platforms with longitudinal mounting. This engine received platform-specific adaptations-shorter intake manifolds in the Stelvio Quadrifoglio and revised exhaust routing in the Giulia Quadrifoglio-and from 2020 received an updated timing chain tensioner to address wear concerns, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The AR 30586's primary reliability risk is premature timing chain tensioner wear on early builds, with elevated incidence in high-RPM usage. Internal Alfa Romeo quality reports from 2021 indicated a notable number of pre-2020 engines requiring tensioner replacement before 60,000 km, while VCA data shows increased camshaft drive failures in poorly maintained units. Extended high-speed operation and delayed servicing increase wear rates, making timing component adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The AR 30586 offers exceptional performance but early models (2018–2019) are prone to timing chain tensioner wear under sustained high-RPM operation. Later revisions (post-2020) significantly improved durability. Regular servicing and inspection of the timing chain and tensioner on high-mileage pre-2020 engines are essential for long-term reliability.
Key issues include premature timing chain tensioner wear (especially pre-2020), intake valve carbon buildup due to direct injection, coolant leaks from the plastic thermostat housing, and ignition coil failures. These are documented in Alfa Romeo service bulletins and technical forums.
This 2.0L turbo petrol engine was used in the Alfa Romeo Giulia Quadrifoglio (2018–2023) and Stelvio Quadrifoglio (2019–2023) as the 2.0 Turbo 280 HP variant. It was not used outside the Alfa Romeo brand and is specific to longitudinal-mounted applications in these models.
Yes. ECU remaps can yield +30–60 kW by optimizing boost and fuel maps. The stock turbo and internals support moderate tuning. Intake and exhaust upgrades enhance responsiveness. Over-boosting should be avoided without supporting modifications.
Moderate. In a Giulia Quadrifoglio, combined consumption is approximately 9.5 L/100km (30 mpg UK). City driving can exceed 12.5 L/100km, while highway cruising achieves around 7.2 L/100km (39 mpg UK). Real-world figures depend heavily on driving style due to the engine's performance character.
Yes. The AR 30586 is an interference engine. If the timing chain fails or jumps, piston-to-valve contact will occur, resulting in severe internal engine damage. Strict adherence to 30,000 km or 2-year inspection intervals is strongly recommended, especially on high-mileage vehicles.
Alfa Romeo specifies SAE 0W-40 synthetic oil meeting ACEA A3/B4 standards. Oil must be changed every 30,000 km or 2 years to ensure proper lubrication of the valvetrain and prevent premature wear. Using incorrect oil can accelerate component degradation.
