The Alfa Romeo AR 67102 is a 1,995 cc, inline — four turbocharged petrol engine produced between 2020 and 2025. It powers Alfa Romeo's performance — focused compact and mid — size models, featuring direct fuel injection, variable valve timing (Dual VVT), and a twin — scroll turbocharger. In standard tune it delivers 180 kW (245 PS), with peak torque of 400 Nm, providing strong mid — range pull and responsive throttle delivery.
Fitted to key models including the Giulia Quadrif…
All production years (2020–2025) meet Euro 6d standards .
The Alfa Romeo AR 67102 is a 1,995 cc inline-four turbocharged petrol engine engineered for performance applications (2020–2025). 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 Alfa Romeo AR 67102 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 2023 received updated fuel system calibration to address HPFP durability. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.

The most common questions about engine codes, what they mean, how to find them and how this database works
The AR 67102 offers strong performance and refinement, but pre-2023 models are prone to high-pressure fuel pump issues under aggressive use. Later revisions (post-2023) show improved reliability with updated ECU mapping and pump calibration. When maintained properly—using correct oil and high-octane fuel—these engines can reliably exceed 150,000 km. Regular inspection of the fuel system and cooling components is recommended.
The most documented issues are high-pressure fuel pump degradation (especially pre-2023), intake valve carbon buildup due to direct injection, and coolant leaks from the thermostat housing. Secondary concerns include timing chain tensioner wear and GPF saturation. These are covered in Alfa Romeo technical bulletins and field service reports.
The AR 67102 was used in the Giulia (Veloce, Quadrifoglio base, 2020–2025) and Stelvio (Quadrifoglio, 2020–2025). It was not used in the full Quadrifoglio V6 variant. All applications meet Euro 6d emissions standards.
Aftermarket ECU tuning is common on the AR67102 platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In real-world driving, expect 10.5–13.0 L/100km (22–27 mpg UK) depending on model and driving style. The Giulia Veloce achieves around 9.8 L/100km (29 mpg UK) on highways. Performance driving significantly reduces economy. Using RON 98 fuel is recommended for optimal efficiency and power delivery.
Yes. The AR 67102 is an interference engine. If the timing chain fails or skips, piston-to-valve contact will occur, resulting in severe internal damage. Proper maintenance, including timely oil changes and tensioner inspections, is essential to prevent costly engine repairs.
Alfa Romeo specifies SAE 0W-40 synthetic oil meeting ACEA C3 standards. This low-SAPS formulation protects the turbocharger and GPF. Oil changes should be performed every 15,000 km or annually. Using the correct oil is critical for long-term reliability of the turbo and timing components.
