Peugeot’s New Turbo 100 Engine: Replacing PureTech & Meeting Euro 7 Standards

Peugeot is addressing a long-running reliability issue with its popular 1.2-liter PureTech engine by introducing the fresh “Turbo 100” petrol engine for the 2026 Peugeot 208 and 2008 models. The shift, announced March 16, 2026, replaces the problematic “wet belt” system with a more durable timing chain, a move expected to significantly reduce maintenance costs and improve customer confidence. The new engine also aims to meet upcoming Euro 7 emissions standards.

The PureTech Legacy and the Need for Change

For over a decade, Stellantis’s 1.2-litre PureTech turbocharged three-cylinder engine (code EB2ADTD) has been a mainstay in numerous models across Peugeot, Citroën, Opel/Vauxhall, DS Automobiles, and Jeep. While praised for its efficiency and power, the engine gained notoriety for a design flaw: a timing belt running through the engine oil. This “wet belt” system, intended to reduce engine length and maintenance, proved prone to premature degradation, leading to costly repairs for owners. CarVira reports the issue turned the engine into “one of the most expensive reliability nightmares in the used car market.”

Engineering the Turbo 100: A 70% Overhaul

The new Turbo 100 engine isn’t simply a refinement of the PureTech; Peugeot states that approximately 70% of its components are new. Key changes include the adoption of a metal timing chain, a redesigned turbocharger, a new high-pressure direct injection system, and revised pistons and cylinder block. Stellantis highlights that the variable-geometry turbocharger provides improved responsiveness at lower engine speeds. The new engine displaces 1.199 cc and delivers a maximum output of 101 hp (74 kW) at 5,500 rpm, with peak torque of 205 Nm available from 1,750 rpm.

Euro 7 Compliance and Efficiency Gains

Beyond addressing reliability concerns, the Turbo 100 is engineered to comply with the forthcoming Euro 7 emissions regulations. The engine incorporates a high-pressure direct injection system, operating at 350 bar, to optimize fuel combustion and reduce emissions. A pop valve system minimizes internal friction, and an improved compression ratio further enhances efficiency. According to Actualidad Motor, the goal is to improve durability, contain fuel consumption, and extend maintenance intervals.

Warranty and Maintenance Schedule

Peugeot is backing the Turbo 100 with an extended warranty of 8 years or 160,000 kilometers, signaling confidence in the engine’s improved reliability. Maintenance intervals are also reduced to a single service every 2 years or 25,000 km, supplemented by an annual intermediate check. Peugeot projects a combined fuel consumption of 5.1-5.2 liters per 100 km and emissions of 116-117 g/km. The engine allows the 208 to reach a top speed of 195 km/h and accelerate from 0 to 100 km/h in 10.1 seconds.

Rollout and Model Availability

The Turbo 100 engine is currently available in the 2026 Peugeot 208, with availability expanding to the 2008 model in May 2026. This phased rollout allows Peugeot to manage production and ensure a smooth transition for dealerships and customers. The introduction of the Turbo 100 represents a significant investment by Stellantis to address a critical weakness in its compact car lineup and restore consumer trust in the Peugeot brand.

Implications for the Used Car Market

The arrival of the Turbo 100 is likely to have a ripple effect on the used car market. Vehicles equipped with the older PureTech 100 engine may experience a decline in resale value as potential buyers become more aware of the potential for timing belt issues. Conversely, the 2026 208 and 2008 models with the Turbo 100 are expected to command a premium due to their improved reliability and longer-term ownership costs. This shift could also influence insurance rates, with insurers potentially offering lower premiums for vehicles equipped with the newer engine.

What to Expect Next

The immediate next step is monitoring real-world performance data from the first vehicles equipped with the Turbo 100. Peugeot and Stellantis will be closely tracking warranty claims and customer feedback to identify any unforeseen issues. Further down the line, the technology is expected to be rolled out to other models within the Stellantis portfolio, potentially including Citroën, Opel/Vauxhall, and DS Automobiles vehicles. The success of the Turbo 100 will be a key indicator of Stellantis’s ability to address past engineering shortcomings and deliver reliable, efficient powertrains to its customers.
