It features direct fuel injection, variable valve timing (VVT), and a twin — scroll turbocharger, delivering 180 kW (245 PS) and 400 Nm of torque. This engine is part of the Stellantis Global Medium Engine (GME) family, designed for high specific output and responsive performance.
Fitted to the Alfa Romeo Giulia and Stelvio Quadrifoglio models, this engin…
Production years 2020–2025 meet Euro 6d standards; no Euro 5 variant of this engine code was certified (VCA UK Type Approval #VCA/EMS/841C000).
The Alfa Romeo 841 C000 – Petrol is a 1,995 cc inline-four turbocharged petrol engine developed for high-performance sedans and SUVs (2020–2025). 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 841 C000 – Petrol was used across Alfa Romeo's 952 platform with longitudinal mounting and shared architecture with Stellantis Group performance vehicles. This engine received platform-specific tuning for sharper throttle response and higher redline in the Giulia Quadrifoglio, and from 2023, updated ECU calibrations improved GPF regeneration efficiency, creating software compatibility limits. All adaptations are documented in OEM technical bulletins.
The 841 C000 – Petrol's primary reliability risk is turbocharger bearing wear under sustained high-load operation, with elevated incidence in track-driven vehicles. Alfa Romeo internal field reports from 2023 indicated over 20% of pre-2022 units required turbo inspection or replacement before 80,000 km, while UK DVSA MOT data shows emissions-related failures are common in modified examples. High-RPM use and delayed maintenance increase thermal stress, making proactive inspection and correct oil usage critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The 841 C000 – 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, track-driven units are prone to turbo 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 turbocharger bearing 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 Giulia and Stelvio Quadrifoglio models from 2020 to 2025. It was designated as the 2.0 Quadrifoglio 245 HP variant. No other Alfa Romeo models or derivatives outside the 952 platform received this specific engine code. It is distinct from the smaller-output GME-T4 units used in the Giulia Veloce or Stelvio Ti.
Yes, the engine responds well to ECU remapping. Stage 1 tunes typically achieve 280–300 PS safely, as the stock turbo and internals are robust. However, increased power raises exhaust temperatures and carbon production, requiring more frequent intake cleaning and careful monitoring of turbo health. Tuning should be performed by specialists familiar with Bosch MED 17.8.8 ECU protocols.
In combined driving, the 841 C000 – Petrol achieves approximately 9.8 L/100km (28.9 mpg UK). Highway consumption can drop to ~7.5 L/100km (37.7 mpg UK), while city driving may reach 12.5 L/100km (22.6 mpg UK). Real-world economy depends on driving style and traffic conditions. Fuel tank capacity is 60 L for balanced range.
Yes. The 841 C000 – 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.
