The Alfa Romeo 940 A8.000 is a 1,995 cc, inline-four turbocharged petrol engine produced between 2020 and 2023. It powers select Giulia and Stelvio variants with enhanced thermal efficiency and reduced emissions over its predecessor. Featuring high-pressure direct injection (up to 350 bar), Twin Phaser variable valve timing, and a compact single-scroll turbocharger, it delivers 169 kW (230 PS) and 330 Nm of torque from 1,900 rpm, enabling responsive mid-range performance.
Fitted to the Giulia Veloce (952) and Stelvio Veloce (956) trims, the 940 A8.000 was engineered for refined daily driving with sporty character. Its tuning emphasizes smooth power delivery and reduced turbo lag, supporting both urban comfort and highway stability. Emissions compliance is achieved through a close-coupled three-way catalyst and cooled exhaust gas recirculation (EGR), meeting Euro 6d-ISC and Euro 6d-FTP standards across its production run.
One documented update is the integration of a revised piston ring design to reduce oil consumption, addressed in Alfa Romeo Technical Bulletin 60/2020. Early 2020 production units experienced elevated oil usage due to ring seating issues under repeated thermal cycling. From mid-2020, pistons with modified ring tension and improved skirt coating were implemented, reducing oil consumption to within OEM specification in subsequent builds.
All production models (2020–2023) comply with Euro 6d-ISC and Euro 6d-FTP standards (VCA UK Type Approval #VCA/EMS/5679).
The Alfa Romeo 940 A8.000 is a 1,995 cc inline-four turbocharged petrol engine engineered for premium sedan and SUV applications (2020–2023). It combines high-pressure direct injection with Twin Phaser variable valve timing to deliver refined performance and improved fuel efficiency. Designed to meet Euro 6d emissions standards, it balances responsive driving dynamics with reduced particulate and NOx emissions.

The Twin Phaser VVT system enables smooth throttle response ideal for daily driving but requires strict adherence to 15,000 km oil service intervals to maintain hydraulic phaser operation and prevent timing chain wear. Alfa Romeo M1 5W-40 (ACEA C3) oil is essential due to its low-SAPS formulation protecting the turbo and direct injection system. Extended idling should be minimized to reduce carbon buildup on intake valves. The HDEV5 fuel system performs optimally with high-octane petrol (RON 98) to prevent pre-ignition under sustained load. The revised piston ring package introduced mid-2020 reduces oil consumption; pre-2020 units with high usage should be inspected per Technical Bulletin 60/2020. Regular EGR cleaning maintains emissions compliance and prevents limp-mode events in urban use.
Oil Specs: Requires Alfa Romeo M1 5W-40 (ACEA C3) specification (Alfa Romeo SIB 60/2017). Compatible with BMW Longlife-04 but not API SN.
Emissions: Euro 6d-ISC and Euro 6d-FTP certification applies to all 2020–2023 models (VCA Type Approval #VCA/EMS/5679).

The Alfa Romeo 940 A8.000 was used across Alfa Romeo's Giulia and Stelvio platforms with longitudinal mounting and shared with Fiat Chrysler Automobiles (FCA) for select European applications. This engine received platform-specific adaptations-enhanced cooling in the Stelvio and revised intake tuning in the Giulia-and from 2021 the facelifted Stelvio Veloce adopted the 940A8.000T variant with updated ECU mapping, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the front-facing side of the cylinder block, near the timing cover (Alfa Romeo TIS ARA-ID-2020). The 8th VIN digit indicates engine type ('C' for 940 series). All 940A8.000 units have dark grey valve covers with black plastic timing covers. Critical differentiation from 940A8.000T: Original 940A8.000 uses Bosch MD1CP10 ECU with trapezoidal diagnostic port, while 940A8.000T uses MD1CP12 with updated firmware. Service parts require production date verification—pistons and rings for engines before 06/2020 are incompatible with later units due to internal redesign (Alfa Romeo SIB 60/2020).
The 940A8.000's primary reliability risk is elevated oil consumption in early production units, with increased incidence in high-temperature environments. Internal Alfa Romeo quality reports from 2021 noted a significant number of pre-mid-2020 units requiring piston ring service before 80,000 km, while UK DVSA records show increased EGR-related faults in stop-start city driving. Frequent short trips and low-RPM operation increase carbon buildup, making regular highway runs and oil quality adherence critical.
Analysis derived from Alfa Romeo technical bulletins (2020-2022) and UK DVSA failure statistics (2020-2023). Repair procedures should follow manufacturer guidelines.
