The Fiat Global Small Engine (GSE) 1.3 is a 1,332 cc, inline‑three turbocharged petrol engine produced from 2016 onwards. It features a lightweight aluminium block, direct fuel injection, and a single twin‑scroll turbocharger, delivering outputs from 96 kW (130 PS) to 110 kW (150 PS) with torque figures of 200–270 Nm. Variable valve timing (MultiAir III) enables precise control for both efficiency and responsive power delivery.
Fitted to models such as the Fiat 500X, Panda, and Tipo, as well as Jeep Renegade and Compass, the GSE 1.3 was engineered for global markets requiring a compact, efficient, yet torquey powertrain. Emissions compliance is achieved through gasoline particulate filtration (GPF) and advanced engine management, meeting Euro 6d standards from its introduction.
One documented engineering focus was mitigating low‑speed pre‑ignition (LSPI) risks inherent in high‑boost, small‑displacement engines. This was addressed in Fiat's Technical Bulletin TSB‑01‑18‑003 through specific calibration updates and the mandatory use of approved low‑SAPS engine oils to protect against abnormal combustion events.
All production years (2016–Present) meet Euro 6d emissions standards for relevant markets (VCA UK Type Approval #VCA/FIAT/GSE13).
The Fiat Global Small Engine (GSE) 1.3 is a 1,332 cc inline‑three turbocharged petrol engineered for global compact SUVs and hatchbacks (2016–Present). It combines direct injection with Fiat's MultiAir III variable valve timing to deliver responsive low‑end torque and efficient cruising. Designed to meet Euro 6d standards from launch, it balances urban agility with highway capability.

The twin-scroll turbo provides strong low-RPM torque ideal for city driving but mandates the use of Fiat-approved 0W-20 low-SAPS oil to prevent LSPI and turbo bearing wear. Extended oil change intervals (up to 20,000 km) are permissible only with the specified oil grade. The GPF requires the use of Top Tier fuel to prevent premature clogging. Coolant should be replaced per the severe service schedule if frequently used for short trips. No major serviceable timing components exist within standard intervals.
Oil Specs: Requires Fiat 9.55535-CR1 (0W-20) specification to mitigate LSPI risk (Fiat SIB TSB-01-18-003).
Emissions: Euro 6d certification applies to all model years (2016–Present) for EU/UK markets (VCA Type Approval #VCA/FIAT/GSE13).
Power Ratings: Measured under SAE J1349 standards. Peak torque requires 95 RON fuel minimum (Fiat TIS Doc. T-GSE-005).

The Fiat Global Small Engine (GSE) 1.3 was used across Stellantis's Small Wide 4x4 and SCCS platforms with transverse mounting. This engine received platform-specific adaptations-different intake manifolds for the Renegade versus the 500X-and from 2020 received a mild-hybrid system (e-Torq) in certain markets, creating minor ECU and wiring harness differences. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front of the cylinder block, near the gearbox flange (Fiat TIS T-GSE-008). The 8th VIN digit typically indicates engine displacement ('3' for 1.3L GSE). Visually, the engine is identifiable by its compact three-cylinder layout and the prominent twin-scroll turbocharger on the exhaust manifold. Critical differentiation for e-Torq models: Look for a 48V belt-starter-generator (BSG) unit mounted on the front of the engine and a larger battery under the passenger seat. ECU part numbers differ between standard and mild-hybrid variants; always verify using the vehicle's diagnostic system before ordering parts.
The GSE 1.3's primary reliability focus is preventing low-speed pre-ignition (LSPI), with elevated risk from using incorrect oil or fuel. Fiat's internal quality data indicates a significant reduction in related warranty claims after the release of TSB-01-18-003, while owner feedback often cites sensitivity to fuel quality affecting GPF regeneration. Adherence to specified fluids and fuels is critical for long-term reliability.
