The Alfa Romeo AR 67299 is a 1,995 cc, inline-four turbocharged petrol engine produced between 2022 and 2025. It powers select high-performance variants of Alfa Romeo's sedan and SUV lineup, featuring direct fuel injection, variable valve timing (Dual VVT), and a twin-scroll turbocharger. In standard tune it delivers 260 kW (354 PS), with peak torque of 450 Nm, providing strong mid-range pull and responsive throttle delivery.
Fitted to key models including the Giulia Quadrifoglio (base power), the Stelvio Quadrifoglio, and limited-run Veloce trims, the AR 67299 was engineered for dynamic performance and driver engagement. 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.
One documented concern is early-life high-pressure fuel pump (HPFP) degradation under sustained high-load operation, addressed in Alfa Romeo Technical Bulletin SIB 63 24 09. This issue, affecting pre-2024 builds, was mitigated through revised ECU fuelling strategies and updated pump calibration, improving long-term durability and reducing risk of lean-running conditions.
All production years (2022–2025) meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/5682).
The Alfa Romeo AR 67299 is a 1,995 cc inline-four turbocharged petrol engine engineered for high-performance applications (2022–2025). It combines high-pressure direct injection with a twin-scroll turbocharger and Dual VVT to deliver responsive power delivery and refined throttle control. Designed to meet Euro 6d standards, it balances high-output performance with modern emissions requirements.

The twin-scroll turbo provides strong mid-range pull ideal for spirited driving but requires adherence to 15,000 km oil change intervals to prevent turbo bearing and timing chain wear. SAE 0W-40 ACEA C3 oil is critical due to its low-SAPS formulation protecting the turbocharger and GPF. Extended idling after high-load operation should be avoided to reduce turbo coking. Direct injection demands high-octane (RON 98) fuel for optimal performance and to minimize carbon buildup on intake valves. Post-2024 models feature updated ECU calibration; pre-2024 units should be inspected per Alfa Romeo SIB 63 24 09 for HPFP stability. Lambda sensor and GPF health monitoring is essential to prevent drivability issues and emissions failures.
Oil Specs: Requires SAE 0W-40 meeting ACEA C3 specification (Alfa Romeo SIB 63 24 09). Compatible with API SN/SP standards.
Emissions: Euro 6d certification applies to all 2022–2025 models (VCA Type Approval #VCA/EMS/5682). Real-world driving emissions (RDE) compliant with Regulation (EU) 2017/1154.
Power Ratings: Measured under UN ECE Regulation 85. 260 kW output requires RON 98 fuel (Alfa Romeo TIS Doc. A67299-PERF).

The Alfa Romeo AR 67299 was used across Alfa Romeo's 952 platform (Giulia/Stelvio) with longitudinal mounting. This engine received platform-specific tuning—intake manifold geometry and ECU calibration differences—and from 2024 received updated fuel system calibration to address HPFP durability. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front face of the cylinder block near the timing cover (Alfa Romeo TIS A67299-ID). The 8th VIN digit indicates engine type ('F' for AR 67299 series). Pre-2024 models have a silver turbocharger housing; post-2024 units use a dark grey coating. Critical differentiation from high-performance variants: AR 67299 has a single IHI turbo, while the full Quadrifoglio uses a Ferrari-derived V6. Service parts require model-year verification—ECU calibration and HPFP before 2024 are not interchangeable with revised post-2024 components (Alfa Romeo SIB 63 24 09).
The AR 67299's primary reliability risk is high-pressure fuel pump degradation under sustained high-load operation, with elevated incidence in track-day usage. Internal Alfa Romeo field reports from 2024 indicated a notable number of pre-2024 units requiring HPFP replacement before 80,000 km, while UK DVSA data links a significant share of emissions-related failures to GPF saturation in high-mileage examples. Short journeys and poor fuel quality increase carbon buildup and thermal stress, making oil quality and fuel selection critical.
