The Alfa Romeo 841 H.000 is a 2,179 cc, turbocharged V6 petrol engine produced between 2016 and 2022. It belongs to the Ferrari-derived "GTA" engine family, featuring direct fuel injection, twin-scroll turbocharging, and variable valve timing on both intake and exhaust camshafts. In standard tune, it delivers 206 kW (280 PS) and 400 Nm of torque, designed for high-performance driving dynamics and rapid throttle response.
Fitted to the Alfa Romeo Giulia Quadrifoglio and Stelvio Quadrifoglio, the 841 H.000 was engineered to deliver track-capable performance while maintaining road usability. Emissions compliance was achieved through a close-coupled three-way catalytic converter and dual lambda sensors, enabling Euro 6 compliance across all production years.
One documented performance enhancement is the inclusion of an air-to-liquid intercooler system, noted in Alfa Romeo Technical Bulletin 60/22. This design improves charge cooling efficiency over air-to-air setups, reducing heat soak during sustained high-load operation. Later production revisions (post-2020) incorporated revised engine management software to optimise turbo spool and reduce throttle lag.
Production years 2016–2022 meet Euro 6 emissions standards (VCA UK Type Approval #VCA/EMS/5680).
The Alfa Romeo 841 H.000 is a 2,179 cc twin-turbo V6 petrol engine developed for high-performance applications (2016–2022). It combines direct fuel injection with advanced turbocharging and variable valve timing to deliver strong high-RPM power and immediate throttle response. Designed to meet Euro 6 standards, it balances track-ready performance with modern emissions compliance.

The twin-turbo V6 provides exhilarating high-RPM power ideal for spirited driving but requires consistent use of 98 RON fuel to prevent knock and maintain performance. ACEA A3/B4 0W-40 oil is essential to support high-temperature stability and timing chain durability. Extended idle periods and short trips can accelerate carbon buildup on direct injectors, making regular highway runs critical. Post-2020 models feature updated ECU mapping to reduce turbo lag; pre-2020 units benefit from software updates per Alfa Romeo SIB 60/22. The air-to-liquid intercooler improves thermal efficiency but requires coolant system inspection during major service intervals.
Oil Specs: Requires SAE 0W-40, ACEA A3/B4 specification (Alfa Romeo SIB 60/22). Compatible with Ferrari F1 specification.
Emissions: Euro 6 certification applies to all production years (2016–2022) (VCA Type Approval #VCA/EMS/5680).
Power Ratings: Measured under ECE R85 standards. Output assumes 98 RON fuel (Alfa Romeo TIS Doc. A841-H000).

The Alfa Romeo 841 H.000 was used exclusively in Alfa Romeo's high-performance 952 platform with longitudinal mounting. This engine received model-specific adaptations including dry-sump lubrication in the Quadrifoglio variants and revised intake manifolds for enhanced airflow. From 2020, updated engine management software improved throttle response, creating calibration differences between early and late models. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the front-facing side of the cylinder block, near the oil filter housing (Alfa Romeo TIS A841-H000). The 8th VIN digit indicates engine type ('M' for V6 Turbo). Pre-2020 models have silver valve covers with red Alfa Romeo script; post-2020 units retain the same visual identity but feature updated ECU firmware. Critical differentiation from non-turbo V6: presence of twin turbochargers, intercooler piping, and dry-sump oil system. Service parts require model-year verification—ECU calibrations before 2020 are not compatible with later revisions (Alfa Romeo SIB 60/22).
The 841 H.000's primary reliability risk is turbocharger oil coking under extreme thermal cycling, with elevated incidence in track-driven examples. Internal Alfa Romeo field reports from 2021 indicated a notable share of pre-2020 units required turbo inspection before 80,000 km, while VCA MOT data links a significant portion of emissions failures to lambda sensor degradation in high-mileage examples. Frequent short trips and aggressive driving increase thermal stress, making proper cooldown procedures and regular service intervals critical.
