A new era for the used car market: the 2026 ecological penalty shakes things up
In 2026, the used car market is poised to undergo a drastic change, driven by an unprecedented ecological penalty. After years of relative stability, soaring prices are accelerating, reigniting the debate on car taxation. On the one hand, this reform aims to encourage the transition to cleaner vehicles, but on the other, it raises palpable concerns about its economic repercussions. Using scales as complex as they are confusing, the government has decided to extend the penalty to vehicles that have been on the road for several years, particularly those from 2015 and newer, thus imposing a retroactive tax. The result? A considerable increase in the acquisition cost of many popular used cars, such as those from Renault, Peugeot, or Citroën, not to mention higher-end models like Mercedes-Benz or BMW, which often have emissions already exceeding the tax thresholds.
With this new legislation, we are seeing a worrying trend: rising prices that are being felt at all levels, from the owner who wishes to resell their vehicle to the future buyer. However, this development is part of a broader context of ecological transition, seeking to reduce the carbon footprint of the French vehicle fleet. The complexity of the penalty scale, established on the basis of CO₂ emissions and subject to discounts based on age or mileage, further complicates the picture. Suffice it to say that, to buy a city car like the Volkswagen Polo or a well-equipped Audi sedan, you now have to reckon with sometimes exorbitant surcharges.
Analyzing this situation, it becomes clear that the dynamics of the used car market could change permanently. Rising prices directly impact consumer confidence, as consumers will face a squeeze on their purchasing power. The question is twofold: will this reform succeed in encouraging a true electrification of the fleet, or will it lead to speculative behavior and tax avoidance? The coming months will be crucial to determine whether this ambitious emissions reduction policy will lead to a concrete improvement in environmental conditions or whether it will further widen the existing economic gap.
The measures introduced for 2026 are both ambitious and complex, combining CO₂ scales, discount coefficients, and pollution thresholds. To better understand the impact on the final price, it is essential to analyze the key elements. Thus, the law stipulates that all cars registered after January 1, 2015, will be affected, with some exceptions. In practice, the scale is standardized with a threshold of 107g/km of CO₂ until 2025, which increases to 112g/km in 2026. For any car exceeding this threshold, a penalty is applied proportionally to its emissions. For example, a Citroën C4 with a gasoline engine emitting 108g/km of CO₂ will have to pay a penalty of €50, whether new or used.
The following table summarizes the main scales and thresholds from 2026:
CO₂ Threshold (g/km)
| Penalty in € | Comment | up to 107 |
|---|---|---|
| — | Exempt from penalty | 108 to 112 |
| 50 | Low tax threshold | 113 to 130 |
| variable, up to 2000 | Increasing penalties | over 130 |
| up to 23668 covered by the maximum penalty | Significant surcharges, often for high-end vehicles | This system, based on proportionality, now favors hybrid and electric vehicles, which practically escape this punitive tax if their emissions are less than 50g/km. A Peugeot hybrid, for example, with emissions around 40g/km, will not be affected by the penalty. On the other hand, BMW or Audi SUVs, often fuel-guzzling, risk seeing their prices explode due to the additional tax. |
Discount coefficients and their influence on the final price
To further complicate the system, the government is considering a rebate, i.e., a reduction in the penalty based on the vehicle’s age and mileage. In practice, a recent car (less than 12 months old) will be penalized more than an older model, even one that emits less CO₂. For models that are 10 to 12 months old, a 12% reduction in the penalty is applied, while beyond 15 years, the penalty is supposed to be completely eliminated.
In concrete terms, a 2021 Peugeot 208 emitting 132g/km of CO₂ could face a penalty of nearly €727 in 2026, a significant sum. More strikingly, a 2022 Volkswagen Passat, which in reality should have benefited from a penalty of around €7,086 in 2022, could see this tax triple simply by changing state, under the pretext of complying with the new scale, despite the depreciation. The complexity of these coefficients raises questions about their objectivity and practical application. Discover used car trends and prices in France.

The Used Car Market in 2026: Boom or Crisis?
According to various sources, several scenarios are emerging:
A scarcity of low-emission vehicles, with prices rising by up to 30% ✨
A rise in electric vehicles that are less expensive to purchase but expensive to maintain ⚡️
- A trend toward the revaluation of high-end vehicles, particularly Mercedes-Benz and BMW, which are struggling to bear the additional cost.
- A strong incentive to purchase used models from brands like Toyota and Nissan, which are more economical in terms of emissions.
- This context could also fuel speculation, with investors seeking to resell their cars before the penalty increases their value. Furthermore, the surge in prices could burst the market bubble, particularly for premium or rare models. The lasting question is whether this temporary increase will stabilize or precipitate a deep crisis, particularly for agencies and individuals. Discover used car prices in real time.

- Which models are most impacted by the 2026 penalty increase?
Vehicles with particularly high fuel consumption or those with older engines are likely to be among the biggest tax favorites. The list of models to watch includes:
Often equipped with TSI engines emitting more than 130g/km, they will be heavily taxed
BMW 3 Series and X5:
- Their diesel or gasoline engines can exceed the threshold, with a penalty of up to several thousand euros Audi A3/A4:
- Gasoline or diesel versions, affected from 113g/km Ford Mondeo and Kuga:
- Very popular second-hand vehicles, particularly the diesel version, with emissions exceeding the limit Mercedes-Benz E and GLC:
- Premium models which, even second-hand, will incur a significant additional cost On the other hand, some more environmentally friendly or hybrid models will be little or not at all impacted:
- Electric vehicles, which remain exempt or very lightly taxed ⚡️ Small city cars like the Toyota Yaris (hybrid) or Nissan Micra, often below the threshold
Dacia or Skoda models, which offer economical and low-emission options
- This This overview quickly shows that the penalty does not affect all models in the same way, a key variable for future buyers and sellers.
- The complexity of taxation: how depreciation and mileage influence vehicle prices in 2026
- It’s not just a simple penalty increase. The legislation also provides for a reduction based on age and mileage. Newer vehicles are more polluting, but also more expensive: the formula is implacable. The depreciation based on the vehicle’s age can significantly reduce the final tax. For example, a car less than 12 months old receives a 12% reduction, while one 15 years old or more can see its penalty adjusted to zero, narrowly avoiding the surcharge.
Similarly, the number of kilometers traveled also plays a role: beyond 45,000 km/year, a usage coefficient applies, increasing the tax. Up to 20,000 km/year, no reduction affects the penalty amount. However, if the car is traveled more than 45,000 km each year, the penalty could increase by 3.5% per year, further impacting the acquisition cost for the future owner. Here is a summary of the parameters and their influence:
Criteria
Impact on the penalty
Concrete example
Age (months)
| Reduction of 12% to 100% | 11-month-old vehicle: penalty reduced by 12% | Annual mileage |
|---|---|---|
| Increase of up to 3.5% per year | More than 45,000 km/year: penalty significantly increased | Recent model versus older model |
| Higher depreciation for recent vehicles | A 2021 Peugeot more expensive than a 2005 model | Risks and opportunities for the used car market in 2026 |
| While legislation tends to cause vehicle taxation to skyrocket, the market could fall into temporary or prolonged instability. Some professionals are already pointing to a huge opportunity for used car specialists, particularly for electric or hybrid vehicles, which avoid punitive taxation. However, others fear a scarcity of affordable vehicles, creating a vicious circle: rising prices, reduced supply, and economic destabilization. | In terms of opportunities, some carriers or car rental companies, such as the BMW M5 or Dacia Jogger, could take advantage of this shift to less polluting or more recent used vehicles, while maximizing their margins. However, for individuals, buying a car in 2025 could become a risky bet if speculation leads to rapid price inflation, particularly in the SUV segment or luxury models like the Lamborghini Urus Hybrid. | or prestige vehicles from Mercedes-Benz. |
The challenges for the coming years are numerous. The implementation of additional measures, such as the revaluation of the conversion bonus or the promotion of electric models, could balance the scales in the medium term. The key, therefore, remains the ability to anticipate this profound change, to avoid being trapped by an unforeseen increase in costs.
The models to favor to avoid the surcharge in 2026: focus on electric and hybrid vehicles
For those who wish to continue investing in vehicles that are minimally impacted by the reform, certain choices are essential. Electric and hybrid vehicles, particularly those from brands like Nissan, Toyota, or Kia, enjoy an obvious advantage: they benefit from a virtually non-existent or very low penalty, below the threshold of 50g/km of CO₂. For example, the Toyota Land Cruiser Hybrid or the Nissan Leaf will be among the most popular in 2026, due to their low tax cost. The strategy therefore consists of prioritizing these models to anticipate the sharp increase in total costs when purchasing used vehicles or replacing them in the short term. The market is thus moving toward a gradual transformation, with demand for flexible and plug-in hybrid models continuing to grow. The rise of mainstream manufacturers, such as Renault with its Zoe or Peugeot with the e-208, reflects this trend. Controlling the total cost of ownership is becoming crucial to address soaring prices and limit the impact of the penalty.
