This Hybrid Engine Prototype Promises New Levels Of Efficiency
Horse Powertrain claims the engine has a peak brake thermal efficiency of over 44 percent, reducing fuel consumption.
THE BREAKDOWN:
- Horse Powertrain has a new hybrid engine concept that it claims can achieve up to 71 miles per gallon combined.
- It runs on 100-percent renewable fuel with a 17:1 compression ratio.
- The engine features several innovations, including a next-generation EGR system, an improved turbo, and more.
Horse Powertrains has a new hybrid engine that it claims can return up to 71 miles per gallon combined. It does this through several innovations that maximize efficiency.
According to the company, the H12 Concept engine can achieve a peak brake thermal efficiency of 44.2 percent. The engine, an evolution of Horses’ HR12, features a 17:1 compression ratio and is designed to run on 100-percent renewable fuel. Horse claims the up to 71-mpg rating is compared to an average passenger car in Europe, and is based on the WLTP.

The engine also has a "next-generation" EGR system, an "optimized" turbocharger, and a "high-energy" ignition system. It pairs with an improved hybrid gearbox that offers improved energy management and reduced internal friction.
Horse and its project collaborator, Repsol, have already produced two prototypes and validated performance, and the company is preparing to produce the engine. Horse expects to have the first vehicle equipped with the new hybrid powertrain ready sometime early this year.
"The Horse H12 Concept is an example of how highly efficient engines and renewable fuels can reduce emissions today, without waiting for future solutions," said Patrice Haettel, Horse Powertrain’s chief operating officer and Horse Technology’s chief executive officer.

Motor1’s Take: Horse Powertrain is doing its best to keep combustion engines alive, pushing to find new ways to improve their efficiency. If the H12 Concept is as efficient as the company claims, we don’t doubt there will be buyers for this, and it's not the only company continuing to embrace gas. General Motors is making huge investments to build its next-generation V8.
