The Alfa Romeo AR 67501 is a 1,995 cc, inline-four, turbocharged petrol engine produced between 2024 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 213 kW (290 PS) and 450 Nm of torque, with hybrid-assisted variants reaching 235 kW (320 PS) in performance applications.
Fitted to models such as the Giulia (952) and Stelvio (954), the AR 67501 was engineered for high-performance driving dynamics and track-capable responsiveness. 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 high-pressure fuel pump (HPFP) wear under sustained high-load operation, noted in Alfa Romeo Technical Bulletin 67/2024. This issue is typically associated with extended service intervals and use of non-specification fuel. Later production units (post-2025) are expected to receive revised internal components and updated lubrication channels to improve durability.
Production years 2024–2025 meet Euro 6d-TEMP emissions standards (VCA UK Type Approval #VCA/EMS/9234).
The Alfa Romeo AR 67501 is a 1,995 cc inline-four turbocharged petrol engine designed for compact and mid-size applications (2024–2025). 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-2025 models are expected to feature revised HPFP internals; pre-2025 units should be inspected per Alfa Romeo SIB 67/2024. 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 67/2024). Compatible with Fiat 9.55575-S1 specification.
Emissions: Euro 6d-TEMP certification applies to all 2024–2025 models (VCA Type Approval #VCA/EMS/9234).
Power Ratings: Measured under ECE R85 standards. Output consistent across EU fuel grades (RON 95).

The Alfa Romeo AR 67501 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 2025 will receive minor internal revisions to the high-pressure fuel pump 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 A20909). The 8th VIN digit indicates engine type ('H' for AR 67501). Pre-2025 models have a silver engine cover with '2.0 Turbo' badge; post-2025 units will feature a black cover with updated branding. Critical differentiation from AR 67302: AR 67501 includes revised ECU calibration and higher boost pressure; AR 67302 lacks performance tuning. Service parts require production date verification—high-pressure fuel pumps before 06/2025 are incompatible with later revisions per Alfa Romeo SIB 67/2024.
The AR 67501's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in mixed urban/highway driving. Internal Alfa Romeo quality reports from 2024 indicated a notable number of pre-2025 engines requiring fuel 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 fuel quality and oil interval adherence critical.
