The Ford NAT is a 1,499 cc, inline‑three turbo‑petrol engine introduced in 2020. It features direct fuel injection, a single twin‑scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it produces 118–140 kW (160–190 PS) with torque ranging from 240–300 Nm, delivering brisk low‑end response ideal for compact and crossover applications.
Fitted to models such as the Puma, Focus, and Kuga—including EcoBoost 155 and 190 variants—the NAT was engineere…
All production years (2020–present) meet Euro 6d emissions standards .
The Ford NAT is a 1,499 cc inline‑three turbo‑petrol engineered for compact and crossover vehicles (2020–present). It combines direct injection with a twin‑scroll turbocharger to deliver responsive low‑rpm torque and refined performance. Designed to meet Euro 6d standards, it balances efficiency with dynamic drivability.

The Ford NAT was used across Ford's C2 platform with transverse mounting and shared with Volvo for certain B3/B4 applications under the Geely partnership. This engine received platform-specific adaptations—reinforced mounts in the Kuga and revised cooling in the Puma ST—and from mid-2022 the HPFP and ECU calibration were updated, creating minor service part distinctions. Partnerships enabled Volvo's B3 (163 PS) to use a detuned variant with identical core architecture. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
Field reports and technical service bulletins highlight component wear patterns under high-load operation. Adherence to manufacturer service intervals and approved fluid specifications is critical for long-term reliability.
Analysis derived from manufacturer technical service bulletins and industry workshop records. Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The NAT offers strong performance and meets strict emissions standards, but early models (2020–mid-2022) had HPFP reliability concerns. Post-update engines show improved durability. Regular servicing with correct 0W-20 oil and avoiding constant high-load use greatly enhance longevity.
Key issues include high-pressure fuel pump wear (pre-mid-2022), intake valve carbon buildup due to direct injection, and GPF regeneration challenges on short-trip driving. Minor oil seepage from the timing cover is also noted. All are documented in Ford service bulletins.
The 1.5L NAT powers the Puma (EcoBoost 155/ST), Focus (EcoBoost 155), and Kuga (EcoBoost 150/190) from 2020 onward. A detuned variant is also used in the Volvo XC40 B3 (163 PS) under the Geely technical partnership.
Aftermarket ECU tuning is common on the NAT platform, but increasing boost or altering engine parameters accelerates component wear, impacts emissions compliance, and may void vehicle warranties. Any modifications should be evaluated carefully by a qualified specialist.
In a Puma EcoBoost 155, expect ~7.2 L/100km (city) and ~5.1 L/100km (highway), or about 47 mpg UK combined. Real-world mixed driving typically returns 42–50 mpg (UK), depending on model, driving style, and trip length.
Yes. The NAT is an interference engine. If the timing chain fails or jumps, piston-to-valve contact can cause catastrophic damage. However, the chain is front-mounted and generally robust with proper maintenance.
Ford specifies 0W-20 synthetic oil meeting WSS-M2C948-B1 (or newer). This low-viscosity oil is critical for HPFP lubrication and GPF compatibility. Change every 15,000 km or annually, whichever comes first.
