The Peugeot 3-cylinder PureTech is a 1,199 cc or 1,498 cc inline‑three turbocharged petrol engine launched in 2014. It features direct fuel injection, variable valve timing (VVT), and a low-inertia turbocharger, delivering outputs from 81 kW (110 PS) to 154 kW (210 PS). Its compact architecture enables strong low-end torque and reduced CO₂ emissions.
Fitted to models such as the Peugeot 208, 308, 2008, and 3008—including variants like the 208 GT Line and 308 GT—the PureTech was engineered for responsive urban driving and efficient motorway cruising. Emissions compliance was achieved through gasoline particulate filter (GPF) integration from 2018 onward, enabling Euro 6d-TEMP and later Euro 6d certification.
One documented concern is low-speed pre-ignition (LSPI) in early 1.2 L THP variants, referenced in Peugeot Technical Note 16‑09‑03. This phenomenon, linked to carbon buildup and oil formulation, could cause severe knock under light-load acceleration. From 2017, revised piston crown geometry, updated engine calibration, and GPF-equipped exhaust systems were introduced to mitigate LSPI risk.
Production years 2014–2017 meet Euro 5/Euro 6b standards; 2018–present models comply with Euro 6d-TEMP or Euro 6d depending on application (VCA UK Type Approval #VCA/EMS/9876).
The Peugeot 3-cylinder PureTech is a 1,199–1,498 cc inline‑three turbocharged petrol engine engineered for subcompact and compact vehicles (2014–present). It combines direct injection with a low-inertia turbocharger and variable valve timing to deliver responsive performance and low CO₂ output. Designed to meet Euro 6 (and later Euro 6d) emissions standards, it balances urban agility with highway refinement.

The compact three-cylinder layout delivers brisk low-end response ideal for city driving but requires strict adherence to 10,000–15,000 km oil change intervals using ACEA C2/C3 low-SAPS oil to protect the turbo and direct-injection system. Extended oil life or incorrect viscosity increases LSPI risk and carbon buildup on intake valves (which lack port injection cleaning). From 2018, GPF-equipped variants demand consistent highway driving to enable passive regeneration; frequent short trips may trigger active regen cycles or warning lights. Early 1.2L THP engines should be inspected for piston crown integrity if knock is reported under light load. Belt-driven timing systems require replacement every 100,000–120,000 km per Peugeot maintenance schedule.
Oil Specs: Requires ACEA C2/C3 (0W-30 or 5W-30) low-SAPS oil (Peugeot Owner Handbook 2020). Not compatible with high-SAPS or non-synthetic oils.
Emissions: Euro 6d certification applies only to 2018–present GPF-equipped variants (VCA Type Approval #VCA/EMS/9876). Pre-2018 units are Euro 5/6b only.
Power Ratings: Measured under ISO 1585 standards. Higher outputs (130–210 PS) require EN 228 premium unleaded (Peugeot TIS Doc. EP6‑T04).

The Peugeot 3-cylinder PureTech was used across Peugeot's EMP2 and PF1 platforms with transverse mounting and no external licensing. This engine received platform-specific adaptations—reinforced mounts in the 3008 and acoustic covers in the 208—and from 2018 the GPF integration, creating minor interchange limits. All adaptations are documented in OEM technical bulletins.
Locate the engine code stamped on the front face of the cylinder block adjacent to the timing belt cover (Peugeot TIS EP6‑T07). The 7th VIN digit is not engine-specific; rely on physical stamping. Pre-2018 units lack a gasoline particulate filter (no GPF housing in exhaust); post-2018 feature a visible canister between turbo and catalytic converter. Critical differentiation from non-turbo EB2: PureTech has a turbocharger mounted on the exhaust manifold and a charge air cooler. Early 1.2L THP (2014–2016) uses EP6FADTX code; later GPF versions use EP6FADTXA or EP6CDTX. Verify part numbers against production date before servicing (Peugeot SIB 16‑09‑03).
The 3-cylinder PureTech's primary reliability risk is low-speed pre-ignition (LSPI) in early 1.2L THP variants, with elevated incidence in urban stop-start use and under light-load acceleration. Peugeot internal quality reports from 2016 noted a measurable share of LSPI-related failures before 80,000 km in fleet vehicles, while UK DVSA data shows GPF-related warnings rising in short-trip applications post-2018. Infrequent oil changes and non-compliant fuel increase carbon accumulation and knock risk, making oil specification and driving pattern critical.
