The Ford NCA is a 999 cc, inline‑three turbocharged petrol engine introduced in 2018. It features direct fuel injection, a twin‑scroll turbocharger, and dual overhead camshafts (DOHC). This EcoBoost unit delivers up to 92 kW (125 PS) and 170 Nm of torque, with technologies like cylinder deactivation enhancing real‑world fuel economy.
Fitted primarily to the fourth‑generation Fiesta and Puma ST‑Line models, the NCA was engineered for urban agility and spirited drivin…
Production years 2018–2020 meet Euro 6d-TEMP standards; 2021–present models meet Euro 6d standards (VCA UK Type Approval #VCA/EMS/5678).
The Ford NCA is a 999 cc inline‑three turbocharged petrol engineered for supermini and compact crossover applications (2018–Present). It combines direct injection with a twin‑scroll turbocharger to deliver responsive performance and class‑leading efficiency. Designed to meet Euro 6d standards, it balances everyday drivability with low emissions.

The Ford NCA was used across Ford's B‑Car platform with transverse mounting. This engine received platform-specific adaptations-reinforced engine mounts in the Puma for handling-and from 2021 the Fiesta facelift models adopted minor ECU updates for Euro 6d compliance, creating software interchange limits. All adaptations are documented in OEM technical bulletins.
The NCA's primary reliability risk is high-pressure fuel pump failure, with elevated incidence in vehicles using lower-grade fuel or with high mileage. Ford FSA 46166 documents this issue for specific production ranges, while owner reports frequently cite stalling incidents. Using fuel below 95 RON and neglecting oil changes make adherence to Ford's maintenance schedule critical.

The most common questions about engine codes, what they mean, how to find them and how this database works
The NCA engine is generally robust with proper care. Its main weakness is the high-pressure fuel pump, addressed by Ford in FSA 46166. Using 95 RON fuel and adhering to the 16,000 km/12-month oil change schedule is crucial for longevity. Later production engines appear more resilient.
The most frequent issues are high-pressure fuel pump failures (FSA 46166), faulty intake manifold runner control actuators, coolant leaks from the thermostat housing, and variable cam timing solenoid malfunctions. These are well-documented in Ford service information.
The NCA 1.0L EcoBoost is found in the eighth-generation Ford Fiesta (from 2018) and the Ford Puma crossover (from 2019). It powers various trim levels, including the 100PS and 125PS variants, and is also used in the Puma's mild-hybrid (MHEV) system.
Yes, the NCA responds well to ECU remapping. Stage 1 tunes can safely increase power to around 150-160 PS. The stock internals are strong, but supporting modifications like an upgraded intercooler are recommended for higher power levels to manage heat.
Official WLTP figures range from 4.8 to 5.4 L/100km (52-58 mpg UK) depending on model and transmission. Real-world mixed driving typically yields 5.5-6.5 L/100km (43-51 mpg UK). The mild-hybrid Puma can achieve slightly better economy in urban conditions.
Yes. The Ford NCA is an interference engine. If the timing chain fails or jumps, the pistons will collide with the open valves, causing catastrophic internal engine damage. Fortunately, the chain is designed to last the engine's lifetime with proper maintenance.
Ford mandates oil meeting specification WSS-M2C945-B, typically a 5W-20 viscosity grade. Using the correct low-SAPS (Sulphated Ash, Phosphorus, Sulphur) oil is vital for protecting the turbocharger, variable valve timing system, and the gasoline particulate filter (GPF).
