The Japanese brand has debuted its Mazda Mobile Carbon Capture system on the track, a prototype that It captures COâ‚‚ directly from the exhaust gases while the car is racing.The debut took place in the demanding Super Taikyu, an ideal environment to test whether this idea can coexist with the pace and temperatures of a real race.
The proposal aligns with the European climate roadmap, which sets stricter limits from 2035 onwards, and with the corporate commitment to carbon neutrality by 2050. With communication aligned with the slogan “The Joy of Driving Fuels a Sustainable Tomorrow“Mazda proposes a multi-solution approach that does not rule out improving combustion engines while electrification advances.
What is mobile carbon capture and how does it work?

The core of the system is a porous zeolite material which, due to its structure, It adsorbs the COâ‚‚ present in the exhaust gases and it's contained in a tank integrated into the vehicle. The key is to do it while in motion and without compromising reliability in such demanding use as competition.
According to the brand, the onboard installation allows for a direct capture at the point of emissionpreventing some of the carbon dioxide from reaching the atmosphere. After the race, that stored COâ‚‚ could be recovered for industrial uses, opening the door to a more circular cycle.
Among the possible uses for the retained gas, applications such as the following are being studied: manufacturing of high-performance carbon materials or its use in greenhouse agriculture to accelerate crop growth. These are known methods in Europe that could make use of the captured COâ‚‚.
The system was presented at the Japan Mobility Show and, since then, has been refined with a view to improving adsorption efficiency. optimize packaging and manage the weight and space of the storage tank, decisive factors for its possible deployment beyond the circuits.
Competition debut: Super Taikyu at Fuji

The first race validation took place at Fuji International Speedway (Oyama), during a four-hour race of the Super Taikyu championship. A Mazda3 race car equipped with the device, in Mazda Spirit Racing 3 Future Concept configuration (No. 55), It was fueled using carbon-neutral HVO100 biodiesel, already introduced into the European market.
The test confirmed that the set could Capture COâ‚‚ under high thermal and mechanical stressMaintaining operational continuity in a real-world setting. Although the brand has not provided specific retention figures, the stated goal is to progressively increase the capture rate at future events.
During the test, key parameters such as the thermal stability of the adsorbent, the backpressure at the exhaust, and the usable capacity of the tank were evaluated. All of this aims to achieve a balance between performance and sustainability. Do not excessively penalize on-track behavior.
- Fuel type: HVO100 with a carbon-neutral balance
- Adsorbent: porous zeolite specific for COâ‚‚
- Stage: 4-hour endurance race on Fuji
- Goal: increase capture efficiency and system robustness
Mazda confirms it will continue testing in upcoming rounds of Super Taikyu to gather more data. adjust the system architecture and explore scalability to street uses, where the work cycle and maintenance needs are different from those of a race weekend.
Implications for Spain and Europe

In the European context, where COâ‚‚ limits for the automotive industry are being pushed and renewable fuels are being promoted, this technological approach could complement the deployment of electrification in fleets and competitions. It is not a single solution, but a possible addition on the road to 2035.
The availability of HVO100 and existing COâ‚‚ valorization chains in the EU would facilitate its integration, provided that technical feasibility and reasonable costs are demonstrated. In Spain, sectors such as greenhouse horticulture They could take advantage of recovered COâ‚‚ for productive purposes, if logistics closes the circle.
Practical aspects remain to be resolved: weight and volume of the system in road cars, frequency of tank emptying, energy consumption of thermal management and verified measurement of footprint reductionCircuit learning can accelerate these responses.
Mazda's strategy follows a multi-technology path: electrification where it makes the most difference, constant improvements in hydrogen engines and renewable fuels, and now, Mobile COâ‚‚ capture as a line of applied researchThe competition, once again, serves as a testing ground for solutions that could eventually reach the public road.
With Fuji's trials and the Japan Mobility Show showcase as a starting point, the brand is focused on increasing capture efficiency and ensuring the durability of the adsorbent. If the results are favorableThe next challenge will be to translate the concept into everyday use scenarios and European regulatory frameworks.
Mazda's initiative shows a pragmatic way to cut emissions in real-world use without giving up research into sustainable fuels and electrification; an approach that adds pieces together for a common goal: less COâ‚‚ emitted per kilometer, even when the traffic light turns green.
