A motorist ordering a thermal SUV in 2026 discovers at the time of registration that the tax bill has jumped by several hundred euros compared to the previous year. Behind this wallet shock lies a chain of regulatory measures, a rapid push towards electric vehicles, and manufacturers reorganizing their offerings at high speed. Here’s what really structures the French automotive market today.
CO₂ penalty and weight tax in 2026: the thresholds that change the game
Since January 1, 2026, the ecological penalty applies from 108 g/km of CO₂, compared to 113 g/km previously. At the same time, the weight tax now affects new cars starting from 1,500 kg instead of 1,600 kg. In practical terms, models like the petrol Peugeot 3008 or the non-rechargeable hybrid Renault Austral are now subject to the penalty or weight tax, whereas they were exempt just a year earlier.
The combined revenues from the penalty and the weight tax have already reached 523.4 million euros in the first half of 2026, on a trajectory towards over one billion euros for the year, a threshold never before reached in France. To follow automotive news on Scoopify, it is evident that these fiscal adjustments are fueling a profound reshaping of the market.
This tightening does not only affect large SUVs. A mid-range diesel family estate easily exceeds 1,500 kg when empty. The purchase price therefore mechanically rises, and field reports show that many individuals only discover the exact amount at the time of ordering, due to a lack of clear information at dealerships.
French automotive market: why sales have dropped by 26% since 2019
A Roland Berger study conducted for the Automotive Platform, Mobilians, Avere, and Sesamlld puts a clear figure on the phenomenon: between 2019 and 2025, the French market for new passenger cars has lost about 580,000 annual registrations, a decrease of 26%.
The analysis breaks down the causes. The CAFE regulation (CO₂ standards imposed on manufacturers’ fleets) and direct taxation alone would account for about 410,000 missing registrations. The rest comes from the rise in catalog prices excluding taxes, the cost of fuels, and the increased lifespan of vehicles on the road.
This direct link between European standards and lost volumes is rarely quantified so precisely. The term “automotive purchasing power crisis” is often used, but the figures show that regulation weighs twice as much as the increase in prices excluding taxes in the collapse of sales.
An aging and transforming fleet
The French vehicle fleet now exceeds 39 million vehicles, with an average age that continues to rise. Households are keeping their cars longer, delaying the purchase of new ones, and turning to used vehicles. This trend reinforces a gap: the models on the road no longer reflect the offerings at dealerships.
Electric vehicles in France: market share rises, taxation follows
In July 2026, more than one in three new car sales was electrified (electric or plug-in hybrid). The increase is significant compared to the previous year. This acceleration is partly linked to manufacturers’ strategies, which are pushing electric model sales to meet CAFE caps and avoid European fines that can reach several hundred million euros.
L’Argus’s analysis highlights that this high market share in July is “artificially high,” boosted by tactical registrations of fleets at the end of the semester. In the field, demand from individuals is growing, but at a less spectacular pace than the raw figures suggest.
The issue of taxing electric vehicles
The Council of Mandatory Levies (CPO) estimated that the rise of electric vehicles could eliminate between 37 and 39 billion euros in annual tax revenues related to fuels. To compensate, the CPO favors a yearly tax on all cars rather than tightening penalties or implementing a per-kilometer tax on electric vehicles.
The planned increase in fuel taxes has been postponed to 2028. The idea of a per-kilometer tax for electric vehicles has circulated, but it is not being considered at this stage in France, despite the British example that foresees a similar system. Feedback on this point varies according to institutional sources.
- The CO₂ penalty and the weight tax target thermal and heavy vehicles, not electric ones for now.
- The purchase bonus for electric cars is being redefined, with proposals from the FNA to refocus aid on renewing the old fleet.
- The fiscal trajectory remains uncertain: government decisions will depend on the actual speed of fleet electrification.
Automakers: Renault, Stellantis, and Chinese brands reshuffle the cards
Renault shows positive dynamics in France, driven by the renewal of its electric and hybrid range. Stellantis, on the other hand, is facing pressure on volumes and the profitability of its European brands. German manufacturers (Volkswagen leading the way) are undergoing a period of heavy industrial restructuring.
The noteworthy fact remains the rise of Chinese brands. BYD, MG, and others are ramping up launches in Europe, but commercial establishment is not without friction. Tensions with European dealers, particularly over payment delays, have been reported. The reliability of the after-sales network remains an open question for these newcomers.
- Renault is focusing on the electric B segment (R5, R4) and on E-Tech hybrids to maintain its market share.
- Stellantis is restructuring its factories and streamlining its platforms to absorb the decline in volumes.
- Chinese manufacturers are offering aggressive pricing, but their ability to retain European customers has not yet been demonstrated.
The French automotive market in 2026 can be viewed through three lenses: a taxation system that heavily influences choices, an electrification accelerated by regulatory constraints rather than just demand, and a redistribution of power between historical manufacturers and new entrants. Buying a new car in France is now as much a fiscal decision as it is an automotive choice.
