Horse Powertrain has announced a new hybrid engine designed for greater energy efficiency, utilizing 100% renewable petrol fuel.

The first demonstration vehicle is expected to be unveiled later this year.

 

More Fuel-Efficient Hybrid Engine

This new system is based on the Horse H12 hybrid engine concept developed in collaboration with the Spanish energy company Repsol.

The H12 engine offers the following features and benefits:

• Maximum brake thermal efficiency rate of 44.2%
• Fuel consumption reading of less than 3.3 liters per 100 km (WLTP testing)
• High compression ratio of 17:1
• New generation exhaust gas recirculation (EGR) system
• High-energy ignition system
• Optimized turbocharger
• Hybrid-specific transmission tuning
• New Repsol lubricant that reduces internal friction

With this new hybrid system, the engine provides a savings of over 40% compared to the average new passenger vehicle in Europe as of 2023.

Furthermore, the use of 100% renewable fuel in a mid-sized car is expected to reduce CO2 emissions by approximately 1.77 tons per year compared to conventional petrol vehicles, based on a driving distance of 12,500 km annually.
