Turbo 100 Engine marks a technical turn in the PureTech family by replacing the oil-bathed belt with a metal chain, expanding revised components, and targeting consumers attentive to durability, maintenance, and efficiency in Peugeot compact models initially sold in the European market.
On March 16, 2026, Peugeot introduced the Turbo 100 engine, an evolution of the 1.2 three-cylinder from the PureTech family, now equipped with a metal timing chain instead of the oil-bathed belt used in previous versions.
Initially, the set arrives in Europe in the Peugeot 208, with a debut scheduled from March 2026, while the Peugeot 2008 is expected to receive the novelty in May of the same year, according to an official statement released by the brand.
This change gains relevance because the oil-bathed belt has become one of the most discussed topics in compact turbo engines, both in Europe and Brazil, due to involving preventive maintenance, wear, and costs in case of failure.

Turbo 100 Engine replaces belt with metal chain
In the timing system, lies the most symbolic change of the new project.
Instead of the oil-bathed belt applied in previous versions of the PureTech, the Turbo 100 now uses a timing chain, a traditional solution in the industry and generally associated with less concern for periodic replacement.
According to Peugeot, the new engine comprises 70% new components by value, including the timing chain, turbocharger, injection system, pistons, engine block, and other structural items.
With this revision, Stellantis repositions the three-cylinder at a time of greater demand for reliability, especially in small turbocharged engines, which need to combine low consumption, quick responses, and predictable maintenance.
Although it preserves the architecture of 1,199 cm³, with three cylinders and turbo, the Turbo 100 underwent a comprehensive review to improve efficiency, torque delivery, and robustness in urban and highway use.
Power, torque, and response at low revolutions
In performance, the engine delivers 101 hp, or 74 kW, at 5,500 rpm, in addition to a maximum torque of 205 Nm from 1,750 rpm, numbers confirmed by Peugeot at the European launch.
Among the features highlighted by the manufacturer is the variable geometry turbocharger, used to improve response at low revs and make the car more agile in accelerations, overtaking, and urban driving.
With this calibration, the aim is to offer a more flexible engine without requiring high revs to deliver power, something important in compact models like Peugeot 208 and 2008.
In addition to the new turbo, the set received a high-pressure direct injection system, now with 350 bar, above the 250 bar of the previous configuration, according to the data released by the brand.
Efficiency involves Miller cycle and reduced friction
To reduce consumption and emissions, Peugeot associates the Turbo 100 with the use of the Miller cycle and a high compression ratio, a combination aimed at improving the thermal efficiency of combustion.
There was also a redesign in the distribution system to reduce internal friction, while the pistons underwent changes in the top and rings, focusing on better sealing and lower oil consumption.
In the cylinder head, the brand mentions the use of an aluminum alloy similar to that applied in diesel engines, as well as new materials in the oil separator to increase the resistance of the set.
This package shows that the switch from belt to chain was not an isolated intervention, but part of a larger update involving internal components, lubrication, injection, and combustion management.
Tests total 30 thousand hours and 3 million km
To support the promise of greater reliability, Peugeot claims that the Turbo 100 underwent more than 30 thousand hours of bench tests and more than 3 million kilometers in real driving.
The validation included vehicles subjected to severe use, with some units exceeding 200 thousand kilometers during the development program, according to the information released by the manufacturer.
In maintenance intervals, the schedule was extended to up to two years or 25 thousand kilometers, with an intermediate annual visual inspection, a condition that may vary according to market, application, and local plan.
In Europe, models equipped with the new engine can also enter the Peugeot Care program, which provides coverage of up to eight years or 160 thousand kilometers, according to the rules of each country.
Oil-bathed belt still generates debate in Brazil
Among Brazilian consumers, workshops, and owners of compact turbo engine vehicles, the discussion about oil-bathed belts remains present, especially because of preventive maintenance and potential repair costs.
General Motors uses turbo engines with oil-bathed belts in models sold in the country, but there is no equivalent announcement of a broad replacement with metal chains in the national lineup.
In this context, Stellantis’ decision in Europe also draws attention outside that market, although the Turbo 100 was initially announced for European Peugeot 208 and 2008, without official confirmation of application in Brazil.
Even with the advancement of electrification, combustion engines continue to be developed, especially for markets where hybrids, electric, and thermal engines are expected to coexist for many years.
In the new phase of PureTech, Peugeot’s bet combines metal chain, variable geometry turbo, higher pressure injection, and Miller cycle to reduce maintenance uncertainties without abandoning efficiency.
