Most cars run on fosil fuels, Petrol, Diesel,
Cars run on fossil fuels, gasoline, vegetable oil, and electricity.
We will have to run electric cars, which exist today. There is talk also of cars that run on compressed air. Hydrogen is another fuel source that will run cars if we can manufacture it cheaply enough, and store it safely in the cars.
As of 2018, most cars run on fossil fuels such as gasoline or diesel; there is an increasing tendency for cars to run on stored electrical energy (batteries), but those cars are still in the minority.
Cars can run on Hydrogen gas, however the car's engine must be modified first.
Gasoline and ordinary diesel fuel are both fossil fuels, so almost all cars run only on fossil fuels.
They could make alternative fuels.

Sure they do. There are over 3.5 million cars in Finland.
Future cars may use bio fuels or solar energy and may be run on water power
For over 100 years, most cars have run on gasoline. At first there were very few gas stations, so many drivers carried cans of spare fuel with them. Cars with gas engines run more quickly than cars with steam engines.
For automobiles with a typical internal combustion engine ("ICE"), fossil fuels (such as gasoline and diesel fuel) and air are necessary. Compressed natural gas and hydrogen can also be used in ICEs. However, electric cars utilize massive batteries for power.
