Renault’s Alpine faces crucial decisions as uncertainty looms for Alpine in Formula 1. The future of Formula One is clouded with uncertainty for Alpine, Renault’s racing team, as it faces a crucial decision: whether to continue developing its own engines or switch to Mercedes power units from 2026.
This decision has far-reaching implications that go beyond technical engineering – it reflects Alpine’s strategy to remain competitive, its financial sustainability and the overall direction of its Formula One programme. The tension surrounding this decision has not only affected the racing team, but has also caused anxiety among Renault employees, particularly those working at the company’s historic engine plant in Viry-Châtillon, France.

“Evidence” for Renault quitting F1
Renault engineers unrest
Renault’s Formula 1 engine division, a cornerstone of the company’s racing heritage, has been thrust into the spotlight. Concerns about job security and the future of the plant have grown in recent months, particularly as talks of switching to customer engines have intensified.
The recent Italian Grand Prix at Monza was more than just another stop on the F1 calendar; it was a stage on which Renault employees made their voices heard. Protests and strikes underlined the high stakes involved, with workers rallying to protect both their jobs and Renault’s rich heritage in motorsport.
The situation has captured the attention of the Formula One world, as the decisions made in the coming weeks will affect not only Alpine’s competitiveness on the track, but also the identity of Renault’s racing programme, which spans over 40 years of engine development and numerous championship wins. As Renault considers its next steps, the company must weigh the financial benefits of switching to a customer engine against the heritage and passion its employees have invested in the sport.

Renault engine workers hit back at Monza: “Without F1, Viry has no purpose”
At the Italian Grand Prix in Monza, Renault’s Formula 1 engine workers at Viry-Châtillon gathered to draw attention to the uncertain future of their plant. This was no ordinary protest; it was a clash between Renault’s corporate decisions and the workers’ passion for Formula One. These workers, whose expertise and dedication have helped power some of the most iconic cars in F1 history, fear that Renault may abandon its own engine programme in favour of becoming a customer team.
Should Renault decide to switch to Mercedes power units, it would mark the end of a 47-year era of Renault engines roaring on the Formula One grid. Since 1979, Renault engines have contributed to 178 Grand Prix victories and 12 World Championships, making Renault the third most successful engine manufacturer in F1 history.
Teams such as Williams, Benetton and Red Bull have all benefited from Renault’s engine expertise and drivers such as Michael Schumacher, Alain Prost and Sebastian Vettel have all won titles in Renault-powered cars. The possible end of this legacy has left the 334 employees at Viry-Châtillon in a state of uncertainty.
Recent challenges have led Renault to rethink its engine programme. Since its last championship win with Red Bull in 2013, the company has struggled to replicate the same level of success, leading to questions about the viability of continuing as an engine manufacturer.
Luca de Meo has been investigating the financial and competitive implications of maintaining an in-house engine programme. The option of switching to Mercedes engines offers a cost-effective and potentially more competitive solution, but it also threatens to end a significant chapter in Renault’s motorsport history.

Renault workers: “Save 50 years of French involvement in F1”
To make their voices heard, around 100 employees from Renault’s Social and Economic Council (CSE) travelled to Monza. They unfurled banners on the grandstands calling on Renault to “save 50 years of French involvement in F1” and listed all the championships won by Renault-powered teams between 1992 and 2013. Despite the protests, the employees maintained their respect for the sport, applauding Alpine drivers Esteban Ocon and Pierre Gasly as they took to the track for free practice.
Clement Gamberoni, an engineer who heads Viry’s turbocharger department, spoke of the importance of their protest.
“We are passionate people. We are very proud to be in F1 and to have the car with our engine on the track. But what we want is not to be against anything…”
We want to bring arguments to change our boss’s mind. He stressed that the Viry plant has a deep connection with F1 and that without the sport it would lose its purpose.
The workers believe there is still time for Renault’s management to reconsider its decision before the 30 September deadline. They hope that by highlighting the plant’s contribution to Renault’s success in F1, they can persuade Renault CEO Luca de Meo to keep the engine development programme alive.

De Meo’s annoucement
In response to the protests and growing speculation, Renault CEO Luca de Meo has sought to reassure both employees and fans that no final decision has been made regarding the company’s future in Formula One engine development. Speaking at the Monza Grand Prix, de Meo explained that the Renault board has four to five weeks to decide on the way forward. He stressed that the goal remains to make the Alpine more competitive by the 2026 season, but that achieving this will require a balance of several key factors.
De Meo was candid about the financial challenges of developing a new engine for 2026, when Formula One regulations are set to change significantly.
The financial burden of creating a competitive engine for the new regulations is immense, and for a company like Renault that is also investing in other areas of its business, the potential cost savings of using a customer engine from Mercedes are hard to ignore.
However, de Meo also acknowledged that the decision is not just a financial one.
“So many other factors are important in this consideration,” he explained, pointing out that the company must also take into account the potential impact on the Renault brand, the morale of its workforce and its legacy in motorsport.

Financial realities: The case for a customer engine
From a purely financial point of view, Renault could make significant cost savings by switching to a customer engine. Developing a new engine for the 2026 regulations would require significant investment, both in terms of technology and human resources. By contrast, buying a proven Mercedes engine would allow Renault to focus on other aspects of its racing programme, potentially providing a stronger, more reliable package at a lower cost.
“If you look at it from a purely financial point of view, how expensive it is to develop a 2026 engine ourselves and how much you could save with a customer engine, there is a huge difference,” says de Meo.
The financial argument is a compelling one, especially in a sport where budgets are tight and every dollar spent has to be justified.
However, Renault’s engine programme is more than just a financial investment; it is part of the company’s identity. Abandoning the engine programme would mean that Renault would no longer be in full control of its competitiveness on the track, and it would also mean the end of decades of innovation and engineering excellence. This is a concern that weighs heavily on the minds of Renault’s employees, who believe that the Viry-Châtillon site has more to offer.

Safeguarding jobs: Viry-Châtillon and the Renault workforce
One of the most critical aspects of the debate is the future of Renault’s Viry-Châtillon plant and its workforce. Although de Meo has given assurances that there will be no job losses, the workforce remains concerned about the future. The Viry plant employs over 300 people, many of whom have dedicated their careers to Formula 1 engine development.
If Renault decides to switch to a customer engine, the future of the plant would be uncertain, with many fearing that the skills and expertise developed over decades could be lost.
Renault has promised to redeploy the workforce to other projects, but for many the emotional attachment to F1 makes this transition difficult to accept. The Viry plant has played a vital role in Renault’s success in motorsport and the thought of losing that link is painful for the workforce.
“Without F1, Viry has no purpose,” says Gamberoni yet again, echoing the sentiments of many employees who feel the plant’s legacy is tied to its involvement in F1.
As the 30th September deadline approaches, Renault’s management is facing a momentous decision that will determine the future of the Alpine Formula One programme and the fate of the employees at Viry-Châtillon.
The choice between continuing as an engine manufacturer or switching to a customer package from Mercedes is not just about cost savings; it is about preserving a legacy and ensuring Renault’s presence in Formula One.
