The Alfa Romeo 844 A2.000 – Petrol is a 1,995 cc inline-four turbocharged petrol engine developed for high-performance compact SUVs and sedans (2022–2025). It integrates advanced direct injection with a low-inertia twin-scroll turbocharger to deliver rapid throttle response and linear power delivery. Designed to meet Euro 6d emissions, it supports Alfa Romeo's performance-oriented powertrain strategy while maintaining road legality and emissions compliance.

The Alfa Romeo 844 A2.000 – Petrol was used across Alfa Romeo's 956 platform with transverse mounting and shared architecture with Stellantis Group performance vehicles. This engine received platform-specific tuning for sharper throttle response and higher redline in the Tonale Quadrifoglio, and from 2024, updated ECU calibrations improved GPF regeneration efficiency, creating software compatibility 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 844 A2.000 – Petrol offers exceptional performance and responsiveness, but long-term reliability depends on driving patterns and maintenance. Engines used for regular road driving with timely oil and filter changes are generally robust. However, performance-driven units are prone to HPFP and thermal management issues. Adherence to service intervals and use of Fiat 9.55535-S3 0W-40 oil significantly improves longevity.
The most common issues are high-pressure fuel pump wear, intake valve carbon buildup, timing chain tensioner wear, and GPF clogging. These are primarily linked to high-RPM operation, short-trip driving, and fuel quality. All are documented in Alfa Romeo service information bulletins, with specific cleaning and replacement procedures outlined.
This engine was used in the Alfa Romeo Tonale Quadrifoglio and Giulia Veloce models from 2022 to 2025. It was designated as the 2.0 Quadrifoglio 290 HP variant. No other Alfa Romeo models or derivatives outside the 956 platform received this specific engine code. It is distinct from the smaller-output GME-T4 units used in the Giulia Sprint or Stelvio Base.
Aftermarket ECU tuning is common on the 844A2000 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 combined driving, the 844 A2.000 – Petrol achieves approximately 10.5 L/100km (26.9 mpg UK). Highway consumption can drop to ~8.0 L/100km (35.4 mpg UK), while city driving may reach 13.5 L/100km (21.1 mpg UK). Real-world economy depends on driving style and traffic conditions. Fuel tank capacity is 60 L for balanced range.
Yes. The 844 A2.000 – Petrol is an interference engine. If the timing chain fails or skips, piston-to-valve contact will occur, resulting in severe internal engine damage. The front-mounted chain is generally durable, but tensioner wear or oil starvation can lead to failure. Any timing-related noise should be investigated immediately.
The engine requires Fiat 9.55535-S3 0W-40 specification oil, which meets ACEA A7/B7 standards. This oil is formulated to protect the turbocharger and timing chain under high thermal load. Oil changes should be performed every 15,000 km or annually, whichever comes first, to maintain engine health and prevent sludge buildup.
