The Alfa Romeo AR 06202 is a 1,995 cc, inline-four turbocharged petrol engine produced between 2016 and 2023. It forms part of Alfa Romeo's global small-engine family, sharing core architecture with FCA's Global Medium Engine (GME) platform. Featuring direct fuel injection, twin-scroll turbocharging, and Dual VVT, it delivers 177 kW (240 PS) and peak torque of 380 Nm, primarily in Giulia and Stelvio Quadrifoglio applications.
Fitted exclusively to high-performance variants of the 952 Giulia and 956 Stelvio, the AR 06202 was engineered for track-capable performance with daily drivability. It achieves emissions compliance via a three-way catalytic converter, closed-loop lambda control, and gasoline particulate filter (GPF), meeting Euro 6c standards for 2016–2018 builds and Euro 6d-TEMP from 2019 onward depending on market-specific OBD calibration.
One documented engineering update is the transition to a high-pressure fuel pump with revised plunger design, introduced in Alfa Romeo Technical Bulletin 61/2019. This modification addressed early reports of fuel delivery instability under sustained high load, improving combustion consistency and injector longevity. Later production engines (post-05/2019) feature this updated pump and recalibrated ECU mapping per engineering change AR-TU-2019-03.
Production years 2016–2018 meet Euro 6c standards; 2019–2023 models comply with Euro 6d-TEMP (VCA UK Type Approval #VCA/EMS/5679).
The Alfa Romeo AR 06202 is a 1,995 cc inline-four turbocharged petrol engine engineered for high-performance applications in the Giulia and Stelvio Quadrifoglio (2016–2023). It combines direct fuel injection with twin-scroll turbocharging and Dual VVT to deliver strong specific output and linear throttle response. Designed to meet Euro 6 emissions standards, it balances track-ready performance with regulated efficiency.

The twin-scroll turbo provides rapid boost onset and strong mid-range pull ideal for spirited driving but demands consistent use of 98 RON fuel to prevent knock and carbon accumulation. Alfa Romeo 9.55535-S2 M1 (0W-30) oil is essential due to its thermal stability and compatibility with the timing chain and turbo bearings. Extended idling should be avoided to reduce coking in the high-pressure fuel system. The HDEV5 fuel system requires regular use of detergent-rich fuel meeting EN 228 to prevent injector fouling. Post-2019 models feature upgraded fuel pumps; pre-2019 units should be inspected per Technical Bulletin 61/2019. Gasoline particulate filter longevity depends on consistent lambda sensor function and avoidance of misfire conditions.
Oil Specs: Requires Alfa Romeo 9.55535-S2 M1 specification (0W-30) (Alfa Romeo SIB 61/2019). Supersedes ACEA A1/B1 and A5/B5.
Emissions: Euro 6c certification applies to 2016–2018 models only (VCA Type Approval #VCA/EMS/5679). Euro 6d-TEMP applies to 2019–2023 depending on market OBD calibration.
Power Ratings: Measured under SAE J1349 standards. 177 kW output requires 98 RON fuel quality and full thermal management (Alfa Romeo TIS Doc. AR-A26016).

The Alfa Romeo AR 06202 was used exclusively in Alfa Romeo's 952/956 high-performance platforms with longitudinal mounting. This engine received platform-specific calibrations—shorter intake runners in the Stelvio Quadrifoglio and revised exhaust manifolds in the Giulia Quadrifoglio—and from 2019 the facelifted Giulia and Stelvio received the AR 06202.TU variant with updated high-pressure fuel pump and ECU calibration, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front cylinder block near the timing cover (Alfa Romeo TIS AR-A24891). The 8th VIN digit indicates engine family ('C' for AR 06202 series). All units have black valve covers with red turbo housings. Critical differentiation from AR 06202.TU: Original AR 06202 uses Bosch MED 17.3.6 ECU with rectangular diagnostic port, while AR 06202.TU uses MEDG17.7.2 with trapezoidal port. Service parts require production date verification - high-pressure fuel pumps for engines before 05/2019 are incompatible with later units due to internal redesign (Alfa Romeo TB 61/2019).
The AR 06202's primary reliability risk is high-pressure fuel pump instability on early builds, with elevated incidence in track use and high-load driving. Internal Alfa Romeo quality reports from 2020 indicated a notable share of pre-2019 engines requiring fuel pump replacement before 80,000 km, while UK DVSA records link a portion of emissions-related MOT failures to GPF saturation in high-mileage units. Aggressive driving and poor fuel quality increase carbon and coking risks, making fuel grade and service adherence critical.
