The Fiat 198 A1.000 is a 1,197 cc, inline-three, turbocharged petrol engine produced between 2020 and 2024. It belongs to Fiat's FireFly Turbo family, engineered for compact urban vehicles with a focus on responsive performance and fuel efficiency. Featuring MultiAir3 technology, dual overhead camshafts (DOHC), and 12 valves, it produces 88 kW (120 PS) with 190 Nm of torque, delivering strong low-end pull ideal for city driving and light highway use.
Fitted primarily to the Fiat 500 (312), Fiat Panda (319), and Fiat Tipo (352), the 198 A1.000 was designed for modern emissions compliance and everyday drivability. Its driving character emphasizes immediate turbo response and smooth power delivery, making it well-suited for urban environments and motorway cruising. Emissions compliance was achieved through a close-coupled three-way catalytic converter and gasoline particulate filter (GPF), enabling Euro 6d certification across its production run.
One documented service concern involves premature wear of the turbocharger wastegate actuator arm, particularly in vehicles subjected to frequent cold starts and short trips. This issue, referenced in Fiat Service Information Bulletin 67/2022, is attributed to thermal stress on the actuator pivot joint under incomplete warm-up cycles. In 2023, Fiat introduced a revised actuator with reinforced pivot bushing and updated control calibration to reduce failure incidence.
All production years 2020–2024 meet Euro 6d emissions standards (VCA UK Type Approval #VCA/EMS/9012).
The Fiat 198 A1.000 is a 1,197 cc inline-three turbocharged petrol engine engineered for compact and subcompact models (2020–2024). It combines MultiAir3 variable valve timing with turbocharging and DOHC 12-valve architecture to deliver responsive urban performance and low fuel consumption. Designed to meet Euro 6d standards, it balances efficiency, emissions compliance, and drivability.

The turbocharged inline-three design with MultiAir3 provides strong low-RPM torque and responsive throttle ideal for stop-start driving but requires regular oil changes to protect the turbo and GPF. Adherence to 120,000 km timing belt replacement intervals is critical to prevent interference engine damage. Use of 95 RON minimum unleaded petrol prevents knock under load. The GPF requires periodic regeneration—frequent short trips can lead to clogging and limp mode. The 2023 actuator update significantly improves turbo reliability—pre-2023 units should be inspected for boost fluctuations. Cooling system maintenance prevents overheating in hot climates.
Oil Specs: Requires SAE 5W-30 meeting API SN/CF or ACEA C2 (Fiat SIB 67/2022). Compatible with long-life specifications.
Emissions: Euro 6d certification applies to all 2020–2024 models (VCA Type Approval #VCA/EMS/9012). No market-specific variants.
Power Ratings: Measured under ECE R85 standards. Output consistent across all markets (Fiat Group PT-2020).

The Fiat 198 A1.000 was used across Fiat's 312/319/352 platforms with transverse mounting and front-wheel drive layout. This engine received platform-specific adaptations-shorter intake manifolds in the Panda and revised engine mounts in the Tipo-and from 2023 the updated turbo actuator created service part differentiation. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped horizontally on the left-side engine block near the transmission bellhousing (Fiat TIS F19800). The 8th VIN digit indicates engine type ('T' for 1.2L FireFly Turbo). Pre-2023 models have silver turbo actuator housings; post-2023 units feature black housings. Critical differentiation: Original actuator has ribbed pivot arm; revised version has smooth finish and updated part number. Service parts require model year verification—turbo actuators for pre-2023 engines are not interchangeable with post-2023 revisions due to internal bushing updates (Fiat SIB 67/2022).
The 198 A1.000's primary reliability risk is turbocharger wastegate actuator wear on pre-2023 builds, with elevated incidence in vehicles used for short urban trips. Internal Fiat quality reports from 2023 indicated a measurable number of pre-2023 engines requiring actuator replacement due to pivot joint failure, while VCA MOT data links a portion of boost-related failures in city-driven 500s to degraded actuator function. Extended service intervals and cold-start driving increase thermal stress, making adherence to 120,000 km intervals critical.
