Peugeot Introduces 'Turbo 100' Engine: A Fresh Start Beyond 'PureTech'

While the push toward electrification continues, its pace has recently shown signs of slowing. As a result, internal combustion engines are regaining relevance, prompting automakers to refine and reinvent traditional powertrains. One of the brands adapting to this shift is Peugeot.

Under the umbrella of Stellantis, Peugeot is preparing to phase out its long-standing PureTech engine family. In its place comes the newly developed “Turbo 100” engine, featuring significant technical upgrades and a fresh engineering approach.

Goodbye PureTech, Hello New Era

Although PureTech engines were praised for their efficiency, they also faced criticism due to reliability issues—most notably the timing belt running in oil, which could degrade over time and cause internal engine problems.

The new Turbo 100 aims to eliminate this concern entirely. While retaining the 1.2-liter three-cylinder configuration, Peugeot has replaced the belt system with a more durable timing chain, significantly improving long-term reliability.

70% New Components

This is far more than a simple rebranding. Peugeot states that approximately 70% of the engine consists of newly developed components, including a redesigned cylinder block, upgraded turbocharger, and advanced fuel injection system.

Operating on the Miller cycle with an increased compression ratio, the engine produces 100 horsepower at 5,500 rpm and 250 Nm of torque at 1,750 rpm.

Durability Over Performance

While the performance figures may not seem groundbreaking, Peugeot’s primary goal with this engine is durability and reliability rather than outright power.

The Turbo 100 has undergone extensive testing, including 30,000 hours on test benches and over 3 million kilometers in real-world conditions. Some test vehicles reportedly exceeded 200,000 kilometers without major issues.

Debut Models

The new engine will first appear in the Peugeot 208, followed by the Peugeot 2008 shortly after.
