The Peugeot 1.6L THP 270 is a 1,598 cc, inline‑four turbocharged petrol engine produced between 2013 and 2018. It features an aluminium block and head, DOHC with 16 valves, and direct fuel injection operating at up to 200 bar. Peak output is 200 kW (270 PS) with 330 Nm of torque, enabled by a twin — scroll turbocharger and variable valve timing for responsive performance.

Production years 2013–2018 meet Euro 5 standards across all markets (VCA UK Type Approval #VCA/EMS/9215).
The Peugeot 1.6L THP 270 is a 1,598 cc inline‑four turbocharged petrol engine engineered for hot hatch applications (2013–2018). It combines direct injection with a twin-scroll turbocharger to deliver high specific output and sharp throttle response. Designed to meet Euro 5, it balances performance with regulated emissions control.

The Peugeot 1.6L THP 270 was used exclusively in Peugeot's performance hatchbacks with transverse mounting. This engine received platform-specific adaptations—reinforced engine mounts in the 308 GTi and unique intercooler routing in the 208 GTi 30th Anniversary—and from 2015 the introduction of the updated high-pressure fuel pump created service part distinctions. No cross-manufacturer sharing occurred. All adaptations are documented in OEM technical bulletins.
The THP 270's primary reliability risk is high-pressure fuel pump (HPFP) failure under sustained high-load driving, with elevated incidence in track-day or aggressive urban use. Peugeot internal quality data from 2016 indicated a notable share of pre-2015 engines requiring HPFP replacement before 80,000 km, while UK DVSA MOT records show catalytic converter degradation linked to rich-running conditions from injector or pump faults. Extended oil intervals and low-octane fuel accelerate wear in both the fuel system and turbocharger, making service discipline critical.
Analysis derived from Peugeot technical bulletins (2013–2017) and UK DVSA failure statistics (2016–2023). 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 THP 270 offers exhilarating performance but early units (2013–2014) are prone to high-pressure fuel pump issues under aggressive use. Later revisions (post-2015) improved HPFP durability. Regular oil changes with ACEA C2 5W-40 and use of RON 98 fuel greatly enhance longevity.
Top issues include high-pressure fuel pump failure, turbo oil coking from heat soak, intake valve carbon buildup, and catalytic converter damage from misfires. These are documented in Peugeot service bulletins M.14.07 and M.15.09, and supported by DVSA MOT data.
The THP 270 powered only two models: the Peugeot 208 GTi 30th Anniversary (2014–2018) and the 308 GTi (2015–2018). It was never used in standard trims or shared with Citroën/DS due to its limited-run performance focus.
Yes. ECU remapping typically yields +20–30 kW safely on stock internals, as the engine already uses reinforced components. Supporting upgrades (intercooler, exhaust, fuel pump) allow stage 2 tuning (~300 PS). Avoid aggressive tuning without fuel system upgrades due to HPFP limits.
Real-world consumption is 8.5–10.5 L/100km (27–33 mpg UK) combined for spirited driving. Highway cruising can achieve 6.8 L/100km (~42 mpg UK), while city use may exceed 12 L/100km. Economy depends heavily on driving style and adherence to cooldown practices.
Yes. The THP 270 is an interference engine. If the timing chain fails or jumps, pistons can contact open valves, causing severe internal damage. However, the chain is robust and designed for life-of-engine use with proper oil maintenance.
Peugeot specifies ACEA C2 5W-40 oil meeting B71 2290 standard. This low-SAPS formulation protects the turbo and emissions systems. Change every 10,000 km or 12 months—whichever comes first—to prevent HPFP and turbo wear.
