The Ford T8DE is a 1,499 cc, inline‑three turbocharged petrol engine produced between 2018 and 2024. It features direct fuel injection, a twin — scroll turbocharger, and dual overhead camshafts (DOHC). In standard form it delivers 110 kW (150 PS) and 240 Nm of torque, optimized for responsive urban driving with strong low‑rpm pull.
Fitted to models such as the Ford Focus (Mk4), Puma, and EcoSport, the T8DE was engineered for compact hatchbacks and crossovers requiring a ba…
All production years (2018–2024) meet Euro 6d emissions standards .
The Ford T8DE is a 1,499 cc inline‑three turbocharged petrol engine engineered for compact hatchbacks and crossovers (2018–2024). It combines direct injection with a twin‑scroll turbocharger to deliver brisk low‑end torque and smooth power delivery. Designed to meet Euro 6d standards, it balances urban agility with highway capability.

The Ford T8DE was used across Ford's C2 and B2E platforms with transverse mounting. This engine received platform-specific adaptations—revised cooling ducting in the Puma and stiffer engine mounts in the EcoSport—and from 2021 the Focus adopted an updated intake manifold to mitigate carbon buildup, creating minor interchange limits. 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.

The most common questions about engine codes, what they mean, how to find them and how this database works
The T8DE is generally dependable with proper maintenance. Its main weakness is intake valve carbon buildup in pre-2021 models due to direct injection only. Using correct 0W-20 oil, avoiding constant short trips, and periodic intake cleaning greatly improve longevity. Most owners report smooth operation when driven with occasional highway use.
The top issues are carbon buildup on intake valves (especially pre-2021), GPF regeneration faults from short-trip driving, and occasional turbo wastegate rattle. Minor oil dilution may occur in very cold climates with frequent cold starts. These are documented in Ford TSBs and are manageable with OEM-recommended practices.
The T8DE powers the fourth-gen Ford Focus (1.5 EcoBoost 150 PS), Ford Puma (155 PS hybrid and non-hybrid), and facelifted EcoSport (2020–2023, 125 PS). All meet Euro 6d and feature GPF, twin-scroll turbo, and DOHC inline-3 architecture.
Aftermarket ECU tuning is common on the T8DE 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 Focus 1.5 EcoBoost 150 PS, expect ~6.8 L/100km (city) and ~4.9 L/100km (highway), or ~47 mpg UK combined. Puma hybrids achieve ~4.6 L/100km. Real-world figures vary, but 45–50 mpg (UK) is typical for mixed driving with regular highway use.
Yes. The T8DE is an interference engine. If the timing chain fails (rare but possible), valve-to-piston contact can cause catastrophic damage. However, the chain is front-mounted and designed for life-of-engine service under normal conditions.
Ford specifies 0W-20 synthetic oil meeting WSS-M2C949-A. This low-viscosity oil is essential for turbo cooling, GPF protection, and fuel system longevity. Never substitute with older 5W-30 specs—doing so may void warranty and increase wear.
Comprehensive technical documentation and regulatory references
EngineCode.uk is operated by Engine Finders UK Ltd. It provides engine-reference information and an optional commercial enquiry service. It is not an official manufacturer website. Check the record's sources and confirm vehicle-specific details before relying on it for parts, repairs or replacement.
Our editorial standard prioritises relevant manufacturer documentation and official regulatory sources. The sources and verification status for a record should be checked alongside the data.
A statement is not verified merely because a source is listed. Where supporting evidence is missing or conflicting, the record should identify that limitation. Please report unsupported or inconsistent information.
