"There is still a lot of potential in combustion engines," has been repeated like a mantra for years. In fact, efficiencies of 48 percent or more can be achieved if certain conditions are met.

China is once again leading the way: only if their combustion engines achieve a defined high thermal efficiency will plug-in hybrids (PHEVs) and range extender models (REEVs) enjoy subsidies under the New Energy Vehicle regulation in the future. No wonder Chinese automakers are currently developing or already mass-producing dozens of efficiency-optimized gasoline engines for PHEVs and REEVs. But Europe is also making progress: the weighting of electric and combustion-engine-driven distances is being modified with the Euro 6e-FCM emissions standard.
