The Alfa Romeo AR 67101 is a 1,995 cc, inline — four turbocharged petrol engine produced between 2023 and 2025. It belongs to the Fiat Global Small Engine (GSE) Turbo family, marketed as "Turboblow" in Alfa Romeo applications. Equipped with MultiAir IV variable valve actuation, gasoline direct injection, and a twin — scroll turbocharger, it produces 207 kW (282 PS) and 400 Nm of torque. This engine was engineered for high — performance dynamics and thermal resilience in mod…
Production years 2023–2025 meet Euro 6d-FULL emissions standards .
The Alfa Romeo AR 67101 is a 1,995 cc inline-four turbocharged petrol engine designed for premium performance applications (2023–2025). It combines MultiAir IV variable valve timing with high-pressure direct injection and aggressive turbocharging to deliver 282 PS and 400 Nm. Integrated with a 48-volt mild-hybrid system, it meets Euro 6d-FULL standards while maintaining sharp throttle response and improved low-end driveability.

The Alfa Romeo AR 67101 was used in Alfa Romeo's 952/956 platform high-performance trims with longitudinal mounting. This engine received model-specific calibrations, including sport-tuned throttle mapping in the Veloce and Ti variants and enhanced thermal management for improved emissions control. From 2023, it featured MultiAir IV, 350 bar fuel pressure, and a 48V mild-hybrid system per Technical Bulletin 57 00 01 25, distinguishing it from earlier GSE units. All specifications 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.
The AR 67101's primary reliability risk is high-pressure fuel pump degradation under sustained high-load conditions, with elevated incidence in vehicles with mixed driving cycles. Internal Alfa Romeo field reports from 2023 indicated a measurable share of units requiring fuel pump replacement before 90,000 km, while VCA emissions data shows increased particulate filter clogging in vehicles with delayed maintenance. Short-trip driving without full warm-up increases fuel system stress, making thermal management and fuel quality adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The AR 67101 is a high-performance engine with integrated mild-hybrid technology, and when maintained properly, it offers strong reliability. Key upgrades like the 350 bar fuel system and active thermal management improve emissions control and efficiency. However, mixed driving or short trips without full warm-up increases fuel system stress. Regular maintenance with correct oil (0W-40 MOPAR S5) and RON 98 fuel is essential for long-term health.
Primary issues include high-pressure fuel pump degradation, MultiAir IV solenoid clogging, 48V iBSG malfunctions, and coolant leaks from electric components. These are documented in Alfa Romeo service bulletins. Using correct oil, avoiding short trips, and following service intervals significantly reduce the risk of major failures.
This 2.0L turbo petrol engine is used in high-performance Veloce and Ti trims with MHEV: the Giulia (952) and Stelvio (956) produced from 2023 to 2025. It is not used in base or Quadrifoglio models. All applications meet Euro 6d-FULL emissions standards with identical core calibration and performance output.
Aftermarket ECU tuning is common on the AR67101 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 mixed driving, expect 9.5–12.0 L/100km (24–30 mpg UK). The Giulia Veloce MHEV averages ~10.8 L/100km (26 mpg), while the Stelvio Ti MHEV consumes slightly more due to weight. Highway efficiency improves to ~7.5 L/100km (38 mpg). Performance driving significantly reduces economy due to aggressive throttle use and turbo boost.
No. The AR 67101 uses a non-interference valvetrain design. If the timing chain fails or skips, piston-to-valve contact will not occur, preventing catastrophic internal damage. However, any timing fault still requires immediate repair to avoid misfires and catalytic converter damage.
Alfa Romeo specifies MOPAR S5 0W-40 (Fiat 9.55535-S3) synthetic oil. This high-temperature, low-SAPS formulation is critical for MultiAir IV system longevity and turbocharger protection. Oil must be changed every 15,000 km or 12 months, whichever comes first, to prevent tappet clogging and oil degradation under high thermal load.
