The global automotive industry is witnessing significant advancement in internal combustion engine engineering. A strategic collaboration between giants in the sector resulted in the creation of a conceptual propellant capable of achieving impressive savings. The project achieves a consumption of less than 3.3 liters for every 100 kilometers driven in the rigorous European cycle. Innovation emerges as a viable alternative for the period of global energy transition.
Development took place under the Horse Powertrain umbrella. The joint venture brings together the technical expertise of Renault and Geely in the search for cleaner mechanical solutions. The mechanical assembly called H12 Concept uses exclusively renewable fuel supplied by Repsol. Essa technological combination promises to drastically reduce the carbon footprint of the circulating fleet without requiring the immediate exchange for fully electric models.
Mechanical Arquitetura raises the bar for thermal efficiency
The heart of the new system is based on a platform already known and tested by the international market. The engineers used the three-cylinder turbo block, originally manufactured in the Valladolid unit, in the Espanha. Este component already equips popular vehicles and high-traffic sports utility vehicles. Based on this solid base, the technical team applied in-depth modifications to extract maximum performance from each drop of fuel injected into the combustion chambers.
The practical result of these structural changes is a thermal efficiency of 44.2%. Este number represents a formidable leap forward for modern mechanical engineering. Conventional gasoline Motoress usually operate in the range of 35% to 40% energy utilization. The remainder of the energy generated by burning ends up dissipated in the form of heat or mechanical friction. Overcoming this technical barrier demonstrates the still untapped potential of thermal systems when combined with smart electrification.
The integrated hybrid transmission plays a key role in mitigating energy losses along the route. The system autonomously manages the interaction between the combustion engine and the electrical assistance components. Lubrificantes with very low friction ensures that moving parts slide with almost zero resistance. The complete set can represent savings of 40% compared to the average new car sold on the European continent recently.
Modificações techniques transform conventional propellant
The transformation of the old HR12 engine into the current high-performance concept required a complete review of its operational parameters. The development team spared no effort in reconfiguring the equipment’s vital systems. The main focus was on optimizing the flow of gases and the precision of the exact moment of ignition within the cylinders.
Diversas innovations were incorporated into the project to ensure compliance with strict consumption and emissions targets. Experts have implemented a package of mechanical and electronic upgrades that work in perfect synchronization. The main structural changes include:
- Adoção has an extremely high compression ratio of 17 to 1.
- Redesenho complete exhaust gas recirculation system.
- Calibração specific and optimized variable geometry turbocharger.
- Instalação of a very high energy ignition system for even burning.
- Gerenciamento advanced electronic coupled hybrid transmission.
- Utilização of special lubricating fluids created by Repsol.
Cada one of these items contributes decisively to the harmonious functioning of the powertrain. The high compression ratio extracts more force from the same amount of air-fuel mixture. The gas recirculation system acts directly to reduce the internal temperature of the chambers. Isso prevents premature detonation and reduces the formation of nitrogen oxides harmful to human health.
Validação on real roads and direct environmental impact
The concept’s performance went beyond laboratory boundaries. The prototypes ran on real roads. The chosen route connected the Spanish cities of Valladolid and Móstoles. The trip served to prove the robustness of the system under varied climatic and topographic conditions, validating the theory in the daily practice of European traffic.
Data collected during field tests confirmed initial theoretical projections. Carbon dioxide emissions were restricted to approximately 76 grams per kilometer traveled. A simple projection illustrates the environmental benefit of this brand. A medium-sized car that travels around 12,500 kilometers per year would no longer release 1.77 tons of greenhouse gases into the Earth’s atmosphere.
The secret behind these impressive numbers also lies in the type of energy used to power the engine. The project uses Nexa 95 gasoline. The innovative product is formulated from organic waste, used frying oils and fats of animal origin. Este fuel completely eliminates the need to extract crude oil from the ground. The great commercial advantage of the product is its immediate compatibility with the current fleet, without the need for costly mechanical adaptations.
Estratégia corporate eyes the future of mobility
The business structure behind the innovation reflects tectonic shifts in the global automotive market. Horse Powertrain operates with a balanced shareholding split between Renault Group and Asian manufacturer Geely. Energy giant Aramco recently joined the business. The company contributed heavy capital and technical knowledge about synthetic fuels. The company already supplies vital components to renowned automakers such as Volvo, Nissan and Mitsubishi.
The company’s installed production capacity approaches the impressive mark of 5 million engines manufactured per year. Essa massive industrial scale has the potential to accelerate the introduction of new technology into diverse international markets. The adoption of highly efficient hybrid solutions gains relevance given the fact that the overwhelming majority of the circulating fleet still depends on burning liquid fuels. The transition to pure electric mobility faces obstacles linked to charging infrastructure and the cost of batteries.
The implementation schedule envisages the assembly of functional demonstrator vehicles by the beginning of 2026. Modelos from several of the group’s brands will be able to serve as test platforms for the final versions of the propellant. The market eagerly awaits the definition of an official date for the start of large-scale production. The success of the project reinforces the thesis that traditional thermal engineering still has a long useful life cycle ahead, as long as it is combined with intelligent electrification and renewable fuels.
