Porsche e-Fuel is a synthetic fuel that is being developed by Porsche, a luxury car manufacturer based in Germany. The fuel is made using electricity and water and is intended to be used as an alternative to traditional fossil fuels, such as gasoline or diesel.

According to Porsche, the e-Fuel is made using a process called "power-to-liquid," which involves using electricity to convert water and carbon dioxide into a synthetic fuel. The company claims that the fuel has the same energy density as gasoline and can be used in any internal combustion engine, including those in existing Porsche models.

Porsche has stated that the e-Fuel has the potential to significantly reduce greenhouse gas emissions and improve fuel efficiency, as it does not produce any emissions when it is burned. The company is currently working to scale up production of the e-Fuel and plans to make it available to customers in the near future.

It is important to note that Porsche e-Fuel is still in the development phase and is not yet widely available to the general public. It is unclear when or if the fuel will be available for commercial use.

It is difficult to accurately estimate the cost of Porsche e-Fuel per gallon, as the fuel is still in the development phase and has not yet been made available for commercial use. The cost of the fuel will likely depend on a variety of factors, including the price of raw materials, production costs, and distribution and marketing expenses.

Porsche has not announced any pricing information for e-Fuel at this time. It is possible that the cost of the fuel may be higher than traditional fossil fuels when it is first introduced, due to the cost of developing and producing it. However, it is also possible that the price of e-Fuel may decrease over time as production becomes more efficient and the technology becomes more widespread.

It is worth noting that the cost of e-Fuel may not be directly comparable to the cost of traditional gasoline or diesel, as these fuels are typically sold by the gallon while e-Fuel may be sold by the liter or in other units of measurement. It is also important to consider the potential cost savings that may be achieved by using e-Fuel, such as reduced fuel costs and lower maintenance expenses due to the reduced wear and tear on the engine.
