To determine the car with the greatest efficiency, we need to calculate the fuel consumption per kilometer for each car.

For the first car:
Fuel consumption per kilometer = 1 liter of fuel / 15 km = 0.0667 liters/km

For the second car:
Fuel consumption per kilometer = 1 liter of fuel / 15 km = 0.0833 liters/km

For the third car:
Fuel consumption per kilometer = 1 liter of fuel / 20 km = 0.05 liters/km

For the fourth car:
Fuel consumption per kilometer = 1 liter of fuel / 20 km = 0.0556 liters/km

The car with the greatest efficiency is the third car, a 1,200 kg car that travels 20 km per liter of fuel.
