The Alfa Romeo AR 67201 is a 1,995 cc, inline-four, turbocharged petrol engine produced between 2021 and 2025. It belongs to Alfa Romeo's FireFly engine family, featuring gasoline direct injection (GDI) and dual overhead camshafts (DOHC). In standard tune, it delivers 140 kW (190 PS) and 300 Nm of torque, with higher-output versions reaching 169 kW (230 PS) in performance trims.
Fitted to models such as the Giulia (952) and Stelvio (954), the AR 67201 was engineered for responsive driving dynamics and refined urban performance. Emissions compliance was achieved through a three-way catalytic converter, closed-loop lambda control, and gasoline particulate filter (GPF), allowing Euro 6d-TEMP compliance across its production run for European markets.
One documented concern is intake manifold runner flap failure under thermal cycling, noted in Alfa Romeo Technical Bulletin 64/2022. This issue is typically associated with prolonged exposure to high exhaust gas recirculation (EGR) temperatures. Later production units (post-2023) received revised polymer blends and updated actuator linkages to improve durability.
Production years 2021–2025 meet Euro 6d-TEMP emissions standards (VCA UK Type Approval #VCA/EMS/8901).
The Alfa Romeo AR 67201 is a 1,995 cc inline-four turbocharged petrol engine designed for compact and mid-size applications (2021–2025). It combines gasoline direct injection with twin-scroll turbocharging to deliver strong mid-range power and responsive throttle delivery. Engineered to meet Euro 6d-TEMP standards, it balances urban drivability with performance-oriented characteristics.

The twin-scroll turbo provides strong mid-range torque ideal for spirited driving but requires strict adherence to 15,000 km oil change intervals to prevent turbo bearing and timing chain wear. SAE 5W-40 ACEA A3/B4 oil is essential to maintain lubrication under high thermal loads. Cold starts should be followed by gradual warm-up to ensure oil circulation to the turbocharger. Direct injection leads to intake valve coking; periodic walnut blasting is recommended. Post-2023 models feature revised intake manifold flaps; pre-2023 units should be inspected per Alfa Romeo SIB 64/2022. The gasoline particulate filter (GPF) requires unleaded petrol meeting EN 228 standards to prevent blockage.
Oil Specs: Requires SAE 5W-40, ACEA A3/B4 specification (Alfa Romeo SIB 64/2022). Compatible with Fiat 9.55575-S1 specification.
Emissions: Euro 6d-TEMP certification applies to all 2021–2025 models (VCA Type Approval #VCA/EMS/8901).
Power Ratings: Measured under ECE R85 standards. Output consistent across EU fuel grades (RON 95).

The Alfa Romeo AR 67201 was used across Alfa Romeo's 952/954 platforms with longitudinal mounting. This engine received platform-specific adaptations-tuned intake manifolds in the Giulia and revised exhaust routing in the Stelvio-and from 2023 received minor internal revisions to the intake manifold runner flap system, creating service part distinctions. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the right-side cylinder block, near the transmission bellhousing (Alfa Romeo TIS A20905). The 8th VIN digit indicates engine type ('E' for AR 67201). Pre-2023 models have a silver engine cover with '2.0 Turbo' badge; post-2023 units feature a black cover with updated branding. Critical differentiation from AR 66303: AR 67201 uses revised intake manifold with integrated runner control; AR 66303 uses earlier flap design. Service parts require production date verification—intake manifolds before 06/2023 are incompatible with later revisions per Alfa Romeo SIB 64/2022.
The AR 67201's primary reliability risk is intake manifold runner flap failure on early builds, with elevated incidence in mixed urban/highway driving. Internal Alfa Romeo quality reports from 2023 indicated a notable number of pre-2023 engines requiring intake system service before 80,000 km, while UK DVSA data shows ignition coil failures as a frequent cause of MOT emissions failures. Short trip driving and delayed maintenance increase thermal stress, making EGR system and oil quality adherence critical.
