The Alfa Romeo AR64304 is a 1,995 cc, inline — four turbocharged petrol engine produced between 2030 and 2035. It forms part of Alfa Romeo's next — generation GSE — T (Global Small Engine — Turbo) family, co — developed within the Stellantis group, featuring gasoline direct injection, dual variable valve timing (Dual VVT), and a compact twin — scroll turbocharger with electric assist. In standard tune it delivers 230 kW (313 PS), with peak torque of 460 Nm available from 2,500…
All production years 2030–2035 meet Euro 7 emissions standards .
The Alfa Romeo AR64304 is a 1,995 cc inline-four turbocharged petrol engine engineered for compact and mid-size performance vehicles (2030–2035). It combines direct fuel injection with dual variable valve timing and a twin-scroll turbocharger with electric assist to deliver responsive throttle characteristics and strong mid-range torque. Designed to meet Euro 7 standards, it integrates a gasoline particulate filter (GPF) to reduce particulate matter emissions.

The Alfa Romeo AR64304 was used across Alfa Romeo's 952/956 platforms with longitudinal mounting in rear-wheel-drive and all-wheel-drive applications. This engine received model-specific tuning—slightly higher boost pressure in the Giulia for performance alignment—and from 2032, the Tonale hybrid variant adopted a downsized version (AR33205), creating interchange limits. 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 AR64304 delivers responsive performance and strong mid-range torque, but pre-2033 models have a known risk of high-pressure fuel pump failure. Later revisions (post-2033) incorporated improved materials and control logic, enhancing durability. When maintained with correct oil (0W-20 ACEA C6) and regular coolant changes, these engines can reliably exceed 180,000 km.
The most documented issues are high-pressure fuel pump wear, intake valve carbon buildup due to direct injection, GPF clogging in city-driven vehicles, and oil leaks from the valve cover gasket. These are supported by Alfa Romeo service bulletins and field reports. Lambda sensor degradation and PCV system clogging are also observed in high-mileage units.
This 2.0L turbo petrol engine was used in the Giulia (2030–2035), Stelvio (2031–2035), and Tonale (2033–2035) trims. It is distinct from the hybrid AR33205 used in electrified variants. All variants meet Euro 7 emissions standards.
Aftermarket ECU tuning is common on the AR64304 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 11.6–14.6 L/100km (20–24 mpg UK) depending on model and driving style. The Giulia achieves approximately 10.4 L/100km (27 mpg UK) on highways. Aggressive driving reduces efficiency significantly due to turbo boost demand. Using premium unleaded (98 RON) may improve responsiveness but has minimal impact on consumption.
Yes. The AR64304 is an interference engine, meaning piston-to-valve contact will occur if the timing chain fails or jumps. This can result in severe internal damage. While the chain is designed for the engine's lifetime, any signs of timing noise or oil starvation must be investigated immediately to prevent catastrophic failure.
Alfa Romeo specifies SAE 0W-20 synthetic oil meeting ACEA C6 standards. This low-SAPS formulation protects turbo bearings, timing chain, and the gasoline particulate filter (GPF). Oil changes should be performed every 15,000 km or annually. Using incorrect oil can accelerate turbo wear and contribute to GPF clogging.
