The Alfa Romeo AR 06416 is a 1,750 cc, inline-four naturally aspirated petrol engine produced between 2012 and 2016. It features multi-point fuel injection, dual overhead camshafts (DOHC), and variable valve timing (VVT) on both intake and exhaust camshafts. In standard tune, it delivers 88 kW (120 PS) at 6,200 rpm and 162 Nm of torque at 4,250 rpm, providing smooth, responsive performance ideal for urban and suburban driving.
Fitted primarily to the Giulietta and MiTo, the AR 06416 was engineered for compact efficiency and agile handling. Its transverse mounting supports Alfa Romeo’s front-wheel-drive architecture, while the lightweight aluminum block contributes to balanced weight distribution. Emissions compliance was achieved through a close-coupled three-way catalytic converter, allowing the engine to meet Euro 5 standards across European markets.
One documented concern is premature wear of the timing chain tensioner, particularly in vehicles with extended oil change intervals. This issue, referenced in Alfa Romeo Service Information Bulletin SIB 09/2013, can lead to chain slack and potential valve train damage. From 2014, revised tensioner materials and updated oil specifications were introduced to improve durability.

All AR 06416 engines comply with Euro 5 emissions standards (VCA UK Type Approval #VCA/EMS/4322).
The Alfa Romeo AR 06416 is a 1,750 cc inline-four naturally aspirated petrol engine engineered for compact Alfa Romeo models (2012–2016). It combines multi-point fuel injection with dual variable valve timing to deliver linear power delivery and high-rpm responsiveness. Designed to meet Euro 5 standards, it balances driving engagement with regulated emissions performance.

The naturally aspirated design provides linear throttle response ideal for city driving but requires regular high-RPM operation to maintain valve train cleanliness. Fiat 9.55535-M2 (5W-30) oil is essential for timing chain lubrication and longevity. Extended oil intervals increase risk of tensioner wear and chain stretch, as documented in Alfa Romeo SIB 09/2013. Oil changes every 15,000 km or 24 months are mandatory. The engine responds well to induction cleaning and spark plug replacement every 60,000 km to maintain peak efficiency.
Oil Specs: Requires Fiat 9.55535-M2 (5W-30) specification (Alfa Romeo SIB 09/2013). Replaces ACEA A1/B1 standards.

The Alfa Romeo AR 06416 was used across Alfa Romeo's 940 platform with transverse mounting. This engine was primarily fitted to base trims of the Giulietta and MiTo, and from 2014 received updated ECU calibrations and tensioner revisions, creating interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the lower front face of the cylinder block, near the transmission bellhousing (Alfa Romeo TIS AR-TIS-06416-ID). The 8th VIN digit indicates engine type ('A' for AR 06416 series). Pre-2014 models have silver valve covers with black plastic intake manifolds; post-2014 units use black valve covers. Critical differentiation from turbocharged variants: AR 06416 lacks turbocharger, intercooler, and high-pressure fuel pump. Service parts require model-year verification—timing tensioners from pre-2014 models are not interchangeable with revised units (Alfa Romeo SIB 09/2013).
The AR 06416's primary reliability risk is timing chain tensioner wear, particularly in vehicles with extended oil change intervals. Internal Alfa Romeo service reports from 2015 indicated over 20% of pre-2014 units required tensioner replacement before 100,000 km, while UK DVSA MOT data links a notable share of engine-related failures to timing chain noise and valve train wear. Infrequent high-RPM operation and poor oil quality increase wear, making adherence to oil specifications and service intervals critical.
