Can combustion engines use e-fuels? Does this affect performance and consumption? A study by the TU Darmstadt, sponsored by the ADAC, comes to a clear conclusion.
Conventional cars and motorcycles with combustion engines can run on fossil-free fuel without the engines or their software having to be adapted. This is the conclusion of a study by the Technical University of Darmstadt funded by the ADAC Foundation.
The fuel tested was Eco100Pro, which is certified as 100 percent non-fossil fuel. The scientists came to the same conclusion on the engine test bench, on the race track at the ADAC XC Cup and in their series of tests with a production car on the road: “No loss of power and torque compared to premium gasoline from the gas station. No higher fuel consumption. No technical risk to the combustion engine. But at least 77 percent less CO2 emissions.”
CO2 savings of up to 92 percent
CO2 emissions are generated during the production and transport of the fuel. “If renewable energy is largely used for production, CO2 emissions can be reduced by up to 92 percent,” said the ADAC Foundation.
ADAC Technical President Karsten Schulze said: “The study results are encouraging and show that existing vehicles can also be converted to sustainable and climate-friendly mobility.” Unfortunately, the progress is still being clouded by the high sales price.
