New hybrid engine using 100% renewable fuel boosts mileage by 40%

Horse Powertrain has developed a new hybrid engine concept, the H12, which runs on 100% renewable fuel and can boost vehicle mileage by up to 40%. The renewable fuel, called Nexa-95 and produced by Spanish energy supplier Repsol, is made from organic waste and cooking oils rather than fossil fuels. The H12 engine, evolved from Horse Powertrain’s HR12 three-cylinder engine, features enhancements such as a turbocharger, a new exhaust gas recirculation system, a tweaked gearbox, and a high-energy ignition system, achieving a 44.2% peak brake thermal efficiency and delivering 71 miles per gallon (3.3 km/L). This represents a significant fuel consumption reduction compared to average internal combustion engines. In addition to improved fuel efficiency, the use of Nexa-95 renewable fuel with the H12 engine can reduce emissions by approximately 1.77 tons per vehicle annually compared to fossil fuel-powered cars.
