Dual fuel cars are vehicles that can run on two different types of fuel. Typically, this refers to cars that can operate on:

  1. Gasoline (petrol) and natural gas (usually compressed natural gas or CNG)
  2. Gasoline and liquefied petroleum gas (LPG or propane)

These vehicles have separate fuel systems for each type of fuel and can switch between them, often with the push of a button. The main advantages of dual fuel cars include:

  1. Flexibility in fuel choice
  2. Potential cost savings, as natural gas and LPG are often cheaper than gasoline
  3. Reduced emissions when running on the alternative fuel
  4. Extended driving range due to having two fuel tanks

It's worth noting that dual fuel systems are different from bi-fuel systems, where the engine runs on one fuel at a time, and flex-fuel vehicles, which can run on varying blends of gasoline and ethanol.
