Renault overtakes Stellantis in market share in September 2026, but remains second on annual cumulative basis

Renault progresses at virtually the pace of the market, Stellantis underperforms

Over the month, the near-stability of the Renault Group's growth relative to the market allows it to capture 26.16% market share, ahead of Stellantis' 26.09%. The latter, whose growth of 1.75% remains significantly below the market's 7.8%, records a relative underperformance, while maintaining its first place on a cumulative basis since January. On a cumulative basis since January, both groups show volume declines: -0.58% for Renault (390,505 units, 26.27% market share) and -1.23% for Stellantis (419,853 units, 28.24%), in a context where electric vehicles now account for 31.40% of the overall car market cumulatively, compared to 18.30% a year earlier.

The Renault brand drives the group, Dacia declines

On the brand side, the Renault Group's momentum is driven by the Renault brand, which surges to 36,660 registrations (+14.73%) for 19.95% market share, and 287,173 units on an annual cumulative basis (+2.78%). Dacia moves against the trend with 10,583 units (-14.12%), a decline confirmed over the year (97,778 units, -10.75%), bringing its monthly market share down to 5.76%. Alpine, on modest volumes, more than doubles its registrations to 827 units (+115.36%). In contrast, Stellantis advances in volume but more slowly than the market, which weighs on its monthly market share.
