The Alfa Romeo AR 67105 is a 2,179 cc, twin — turbocharged V6 petrol engine produced between 2020 and 2025. It forms part of Alfa Romeo's Hurricane engine family, featuring gasoline direct injection and dual overhead camshafts (DOHC). In standard tune, it delivers 221 kW (300 PS) and 400 Nm of torque, with higher — output variants reaching 283 kW (385 PS) and 600 Nm, primarily used in Alfa Romeo's performance — oriented platforms.
Fitted to models such as the Giulia Quadrifogl…
Production years 2020–2025 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/7890).
The Alfa Romeo AR 67105 is a 2,179 cc twin-turbocharged V6 petrol engine designed for high-performance applications (2020–2025). It combines gasoline direct injection with twin-scroll turbocharging to deliver strong mid-range and high-end power. Engineered to meet Euro 6d standards, it balances track-ready performance with acceptable emissions compliance for road use.

The Alfa Romeo AR 67105 was used across Alfa Romeo's 952/954 platforms with longitudinal mounting and performance tuning. This engine received platform-specific adaptations-tuned intake manifolds in the Giulia Quadrifoglio and revised exhaust routing in the Stelvio Quadrifoglio-and from 2022 received minor internal revisions to the high-pressure fuel pump system, creating service part distinctions. All adaptations are documented in OEM technical bulletins.
The AR 67105's primary reliability risk is high-pressure fuel pump wear on early builds, with elevated incidence in track-focused driving. Internal Alfa Romeo quality reports from 2022 indicated a notable number of pre-2022 engines requiring fuel system service before 80,000 km, while UK DVSA data shows ignition coil failures as a frequent cause of MOT emissions failures. Short trip driving and low-quality fuel increase stress, making fuel quality and interval adherence critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The AR 67105 offers exceptional performance and responsiveness, but early models (2020–2021) had reliability concerns, particularly high-pressure fuel pump wear. Later revisions (post-2022) improved pump durability, so well-maintained examples can be robust. Regular servicing and using high-quality oil (0W-40 ACEA A3/B4) significantly enhance longevity.
The most frequent issues include high-pressure fuel pump wear, ignition coil carbon tracking, timing chain tensioner wear, and intake valve coking. These are documented in Alfa Romeo service information bulletins and supported by workshop repair data.
The AR 67105 was exclusively used in the Alfa Romeo Giulia Quadrifoglio (952) and Stelvio Quadrifoglio (954) from 2020–2025, both in 2.2 V6 Bi-Turbo 385 HP configuration. It was not used in non-Quadrifoglio variants or other Fiat Group brands in European markets.
Yes. The AR 67105 responds well to ECU remapping, with stage 1 tunes typically adding +30–50 kW. The stock turbos and internals support moderate increases, but supporting mods (intercooler, exhaust, fuel pump) are recommended for higher power levels. Tuning should be performed by specialists familiar with Alfa Romeo engine management.
In combined driving, the AR 67105 achieves approximately 11.2 L/100 km (25 mpg UK) in the Giulia Quadrifoglio. Real-world consumption varies with driving style; aggressive use can exceed 15 L/100 km, while careful driving may achieve 9.5 L/100 km (30 mpg UK).
Yes. The AR 67105 is an interference engine. If the timing chain fails or skips, piston-to-valve contact is likely, resulting in severe internal damage. Proper maintenance and timely inspection of the chain system are essential to prevent costly repairs.
Alfa Romeo specifies SAE 0W-40 synthetic oil meeting ACEA A3/B4 standards. Oil changes should be performed every 15,000 km or annually to protect the turbochargers and timing system. Using incorrect oil can accelerate wear in high-temperature components.
