The Alfa Romeo AR 67105 is a 2,179 cc, twin-turbocharged V6 petrol engine produced between 2020 and 2025. It forms part of Alfa Romeo's Hurricane engine family, featuring gasoline direct injection and dual overhead camshafts (DOHC). In standard tune, it delivers 221 kW (300 PS) and 400 Nm of torque, with higher-output variants reaching 283 kW (385 PS) and 600 Nm, primarily used in Alfa Romeo's performance-oriented platforms.
Fitted to models such as the Giulia Quadrifoglio (952) and Stelvio Quadrifoglio (954), the AR 67105 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 compliance across its production run for European markets.
One documented concern is high-pressure fuel pump (HPFP) wear under sustained high-RPM operation, noted in Alfa Romeo Technical Bulletin 63/2021. This issue is typically associated with extended service intervals and use of non-specification fuel. Later production units (post-2022) received revised fuel rail dampers and upgraded pump internals to improve durability.
Production years 2020–2025 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/7890).
The Alfa Romeo AR 67105 is a 2,179 cc twin-turbocharged V6 petrol engine designed for high-performance applications (2020–2025). It combines gasoline direct injection with twin-scroll turbocharging to deliver strong mid-range and high-end power. Engineered to meet Euro 6d standards, it balances track-ready performance with acceptable emissions compliance for road use.

The twin-turbo setup provides strong mid-to-high RPM power ideal for spirited driving but requires strict adherence to 15,000 km oil change intervals to prevent turbo bearing and timing chain wear. SAE 0W-40 ACEA A3/B4 oil is essential to maintain lubrication under extreme thermal loads. Cold starts should be followed by gradual warm-up to ensure oil circulation to both turbos. Direct injection leads to intake valve coking; periodic walnut blasting is recommended. Post-2022 models feature revised fuel rail dampers; pre-2022 units should be inspected per Alfa Romeo SIB 63/2021. The gasoline particulate filter (GPF) requires unleaded petrol meeting EN 228 standards to prevent blockage.
Oil Specs: Requires SAE 0W-40, ACEA A3/B4 specification (Alfa Romeo SIB 63/2021). Compatible with Fiat 9.55575-S2 specification.
Emissions: Euro 6d certification applies to all 2020–2025 models (VCA Type Approval #VCA/EMS/7890).
Power Ratings: Measured under ECE R85 standards. Output consistent across EU fuel grades (RON 98).

The Alfa Romeo AR 67105 was used across Alfa Romeo's 952/954 platforms with longitudinal mounting and performance tuning. This engine received platform-specific adaptations-tuned intake manifolds in the Giulia Quadrifoglio and revised exhaust routing in the Stelvio Quadrifoglio-and from 2022 received 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 left-side cylinder block, near the transmission bellhousing (Alfa Romeo TIS A22905). The 8th VIN digit indicates engine type ('D' for AR 67105). Pre-2022 models have a red-painted engine cover with 'Quadrifoglio' badge; post-2022 units feature a black cover with updated branding. Critical differentiation from AR 67104: AR 67105 uses dual IHI turbochargers (IHI IS2A-25GK-71.5), while AR 67104 uses single-turbo configuration. Service parts require production date verification—fuel pumps before 06/2022 are incompatible with later revisions per Alfa Romeo SIB 63/2021.
The AR 67105's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in track-focused driving. Internal Alfa Romeo quality reports from 2022 indicated a notable number of pre-2022 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 low-quality fuel increase stress, making fuel quality and interval adherence critical.
Analysis derived from Alfa Romeo technical bulletins (2020–2025) and UK DVSA failure statistics (2020–2023). Repair procedures should follow manufacturer guidelines.
