Horse Powertrain, the joint venture between Geely and Renault, has unveiled a next-generation hybrid powertrain that operates on 100% renewable petrol and boasts ultra-high efficiency and low fuel consumption.
Running on Repsol’s 100% renewable fuel, the hybrid powertrain features the Horse H12 Concept engine, which is an evolution of the H12 engine (like the one found in the Nissan Kicks e-Power) that includes a combustion system designed at a 17:1 compression ratio.
Other key aspects include a new exhaust gas recirculation (EGR) system, an optimised turbocharger, a high-energy ignition system, reduced internal friction enabled by Repsol lubricants as well as an improved hybrid gearbox with optimised energy management.
Designed in Spain in collaboration with Horse Technologies, a division of Horse Powertrain, the first two prototypes of the H12 Concept engine have already been produced and their performance validated. The company expects its first demonstrator vehicle sporting the engine to be presented in early 2026.
According to the company, the H12 Concept engine achieves a peak brake thermal efficiency (BTE) – the ratio of power output to fuel energy input – of 44.2%. Compared to the average fuel consumption of new passenger cars registered in Europe in 2023, the H12 sees 40% lower fuel consumption at 3.3 litres per 100 km following the WLTP standard.
Horse Powertrain claims in its release that a mid-sized car equipped with the H12 Concept hybrid powertrain and averaging 12,500 km per year would emit 1.77 tonnes of CO2 per year less than a vehicle with a conventional combustion engine and traditional fuel.

So how many horses this Horse has? LOL

Now one would really appreciate the Toyota Dynamic Force Engine has a 40% Thermal Efficiency released back in 2017 without any help from hybrid and turbo now that is still an achievement.
ccp engines nowadays can achieve 46% , also without any help from hybrid or turbo, is that even a greater achievement?
