The Fiat 192 A3.000 – Petrol is a 1,368 cc, inline-four, naturally aspirated engine produced between 2016 and 2023. It features a DOHC 16-valve configuration with MultiAir III variable valve timing and port fuel injection, delivering 55 kW (75 PS) at 6,000 rpm and 123 Nm of torque at 2,750 rpm. The MultiAir III system enables fully variable intake valve lift and timing, improving low-end responsiveness and fuel efficiency.
Fitted primarily to the Fiat 500X (334-series) and Fiat 500L (334L), the 192 A3.000 was engineered for urban and light suburban use with a focus on drivability and emissions compliance. It meets Euro 6b standards through a close-coupled three-way catalytic converter, dual lambda sensors, and cooled exhaust gas recirculation (EGR). The engine uses a timing belt-driven valvetrain and front transverse mounting.
One documented concern is premature wear of the MultiAir electro-hydraulic control unit, noted in Fiat Service Information Bulletin 51/2018. This issue, affecting units produced before mid-2019, can result in reduced torque and increased fuel consumption. In 2019, Fiat introduced an updated control unit with improved sealing and revised hydraulic circuit design to enhance long-term durability.
Production years 2016–2018 meet Euro 6b standards; 2019–2023 models comply with Euro 6d-TEMP (VCA UK Type Approval #VCA/EMS/7890).
The Fiat 192 A3.000 – Petrol is a 1,368 cc inline-four naturally aspirated engine designed for compact crossover and MPV applications (2016–2023). It integrates MultiAir III variable valve timing with port fuel injection to enhance low-RPM torque and fuel economy. Engineered to meet Euro 6b and Euro 6d-TEMP emissions standards, it supports responsive city driving while maintaining regulatory compliance.

The MultiAir III system enhances low-speed drivability and fuel efficiency but requires strict adherence to the 120,000 km or 6-year timing belt service interval to prevent interference engine damage. SAE 5W-30 oil meeting API SN/CF specifications is required to maintain hydraulic actuator performance and valve train longevity. Use of low-octane fuel may trigger knock sensor intervention, reducing throttle response. The MultiAir control unit upgrade (Fiat SIB 51/2018) should be installed during service on pre-2019 engines. Emissions compliance depends on intact lambda sensor operation and avoidance of prolonged short-trip driving.
Oil Specs: Requires SAE 5W-30, API SN/CF specification (Fiat SIB 51/2018). ACEA A1/B1 compliant oils are acceptable.
Emissions: Euro 6b certification applies to 2016–2018 models (VCA Type Approval #VCA/EMS/7890). Euro 6d-TEMP applies from 2019 onward, verified under EU Regulation (EC) No 715/2007 and UN R83.
Power Ratings: Measured under ECE R85 standards. Output remains consistent across fuel grades ≥95 RON (Fiat TIS Doc. A192-602).

The Fiat 192 A3.000 – Petrol was used across Fiat's 334 platform with transverse mounting and shared with Lancia for badge-engineered variants. This engine received platform-specific adaptations-revised ECU mapping in the 500X and enhanced cooling in the 500L-and from 2019 the updated 500X Cross models adopted Euro 6d-TEMP-compliant calibration, creating emissions-based interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped vertically on the right-side cylinder block near the oil filter housing (Fiat TIS A192-605). The 8th VIN digit indicates engine type ('D' for 192 A3.000). Pre-2019 models have a silver MultiAir control unit housing; post-2019 units use a black housing with revised O-ring seal. Critical differentiation from turbo variants: 192 A3.000 has no intercooler or boost control solenoid. Service parts require model-year verification—MultiAir control units for pre-2019 engines are incompatible with post-2019 revisions due to internal hydraulic circuit updates (Fiat SIB 51/2018).
The 192 A3.000’s primary reliability risk is MultiAir control unit degradation on early builds, with elevated incidence in high-mileage urban applications. Internal Fiat quality reports from 2020 noted increased failure rates in pre-2019 units exceeding 100,000 km, while UK DVSA records show related DTCs contributing to emissions-related MOT advisories. Infrequent servicing and poor oil quality accelerate wear, making fluid adherence and timely inspection critical.
