Horse Powertrain presented a new automotive powertrain concept capable of redefining economic standards in the global industry. The company developed the H12 hybrid engine, a project focused on maximum mechanical energy extraction. The equipment records a consumption of just 3.3 liters for every 100 kilometers driven in the rigorous WLTP test cycle. The brand represents a significant advance for the passenger vehicle segment, which seeks viable alternatives to purely electric cars. Engenheiros focused on extreme reduction of internal friction and optimization of fuel burn to achieve the feat.
The project combines the technical expertise of automakers with the chemical innovation of the Spanish oil company Repsol. The system runs exclusively on 100% renewable fuel. The combination delivers a thermal efficiency of 44.2%, an unprecedented number for large-scale production engines. Especialistas from the automotive sector see the movement as a direct response to the global energy transition in 2026. The technology extends the useful life of internal combustion engines within a scenario of increasingly strict environmental rules in large cities.
Advanced Engenharia and industry-record thermal efficiency
The development of the project took place at the company’s facilities in Valladolid, in Espanha. The research team used the well-known HR12 engine as a basis. Este 1.2-liter three-cylinder engine already equips popular models in the European and Latin American markets. Technicians dismantled the original architecture to apply new thermodynamic and mechanical concepts. The central objective was to overcome the historic thermal efficiency barrier that has limited the industry for decades.
Traditional gasoline Motoress operate at an efficiency ranging between 35% and 40% at best. The remainder of the energy generated by burning the fuel is irretrievably lost in the form of heat dissipated by the radiator or mechanical friction between moving parts. The new concept reaches the mark of 44.2% of real use. The percentage gain seems small at first glance, but it represents massive fuel savings when applied on a global scale. The improvement requires much more resistant internal components, special metal alloys and extremely high-precision electronic management.
Spanish researchers integrated cutting-edge technologies to achieve the expected result. The ignition system received high-energy coils to ensure complete and rapid burning of the mixture inside the cylinder. Refrigeration has also undergone drastic changes in liquid flow. Water now reaches critical areas of the head with greater speed and pressure. Isso prevents premature detonation and allows smooth operation even at high driver demands.
Especificações techniques of the new hybrid propellant
The H12 architecture incorporates solutions previously restricted to competition vehicles or university test laboratories. The engineering team changed fundamental parameters of basic mechanical functioning. The modifications ensure that every drop of fuel generates as much useful work as possible to move the wheels. The update package includes deep interventions in the block’s structure.
- High compression Taxa for extreme 17:1 aspect ratio.
- Completely redesigned exhaust gas recirculation Sistema.
- Adoção of a specific Miller cycle to optimize valve opening times.
- Velas high energy ignition for instant combustion of the mixture.
- Smart thermal Gerenciamento with variable flow water pumps.
- Calibração exclusive electronics for the use of Repsol’s sustainable fuel.
The combination of these six elements completely transforms the engine’s behavior during operation. The 17:1 compression ratio extracts more force from the explosion, while the Miller cycle reduces the mechanical effort required to compress the air in the intake phase. The practical result is quieter, more efficient operation and free from unwanted vibrations that tend to bother cabin occupants.
Combustível renewable and direct impact on emissions
Advanced hardware depends on a specific input to reach the numbers released by manufacturers. Repsol supplied Nexa 95 fuel for the bench tests and virtual run-in simulations. The product is created from the industrial processing of organic waste, used cooking oils and leftovers from the agricultural industry. The final chemical composition perfectly imitates the properties of traditional fossil gasoline found at gas stations.
The main advantage of the Nexa 95 lies in its direct use in the tank. The driver does not need to adapt the vehicle or install additional components to use the sustainable liquid. The fuel flows through the original supply lines and injection nozzles without causing corrosion or drying out of rubbers and seals. Clean burning also reduces carbon buildup on valves over years of continuous use.
The project’s environmental data shows a drastic reduction in the transport sector’s carbon footprint. The system emits just 76 grams of carbon dioxide per kilometer traveled under ideal conditions. An average driver, who drives around 12,500 kilometers per year, would no longer release 1.77 tons of polluting gases into the atmosphere annually. The bill considers the complete life cycle of the fuel, from the collection of cooking oil to its exit through the car’s exhaust pipe.
Corporate Estratégia and Next Steps for Consumers
Horse Powertrain operates as an independent entity in the competitive global auto parts market. The company has its administrative headquarters at Londres and operates with a strategically divided shareholding structure. Renault Group and Geely each hold 45% of the shares. Saudi oil company Aramco acquired the remaining 10% in early 2024. The joining of forces guarantees robust financial capital for research and development of new propulsion technologies.
The industrial capacity of the joint venture impresses the international automotive market. The company produces around five million engines per year in several factories spread across different continents. The client portfolio includes major brands such as Dacia, Nissan and Mitsubishi, as well as the project’s founders themselves. The colossal scale of production makes it possible to dilute the high development costs of complex projects such as the new high-efficiency propellant. The strategy makes the technology accessible to entry-level vehicles, preventing innovation from being restricted to luxury cars only.
The official schedule foresees the assembly of the first demonstration vehicle at the beginning of 2026. Engineers will carry out tests in real traffic conditions, facing heavy congestion, extreme temperature variations and different geographic altitudes. The success of this practical phase will determine the speed at which the technology reaches dealerships. Modelos compacts and sports utility vehicles appear as the natural candidates to debut the new product on the streets in the coming years.
