The hydrogen-based fuel will be ready for testing in 2022, including in the new Porsche 911 GT3 Cup race car.

EVs are the future, but vehicles with internal-combustion engines are not going to disappear any time soon, which is why synthetic fuels could provide a greener option for the vast majority of the cars on the road today.

The eFuels that Porsche is testing use CO2 and hydrogen ingredients and are made using renewable energy, which significantly lowers the greenhouse gas emissions compared to petroleum-based fuels.
Porsche is far from first to dip into synthetic-fuel research. Audi, Bosch, and McLaren have all been talking about and working on the technology for years.

In the race for greener mobility, nearly every automaker is now focused on electric vehicles. But buying an EV doesn’t change the fact that the vast majority of cars being sold today are powered by gasoline, and they're going to remain on the road for a long time. As a way to make driving existing vehicles more sustainable, Porsche has been working on synthetic fuels it calls eFuels that the company says can make an internal-combustion engine as clean as an EV.
