Actually, no. There are diesel cars which burn 3 litres of diesel on 100
kilometers for the *entire car*. Which means 3 litres for 4 passengers,
or even 5 if you accept to be stuffed like in an airplane.

Hard to fit five passengers into a modern car. Usually there are two
seats in the front and three seatbelt positions in the rear, for a total
of five occupants, one of whom is the driver.
