How Much Higher Is the Fuel Consumption of a 2.0 Compared to a 1.5?

1.5 and 2.0 displacement differ by approximately 2.5 liters per 100 kilometers. Below is relevant information about car displacement: 1. Cylinder working volume: Displacement refers to the exhaust volume, and cylinder working volume refers to the volume swept by the piston from top dead center to bottom dead center, also known as single-cylinder displacement, which depends on the cylinder bore and piston stroke. Engine displacement is the sum of the working volumes of all cylinders, generally expressed in liters (L). 2. Displacement levels: The displacement of micro cars is less than or equal to 1.0L; the displacement of ordinary cars ranges from 1.0 to 1.6L; the displacement of mid-size cars ranges from 1.6 to 2.5L; the displacement of upper mid-size cars ranges from 2.5 to 4.0L; and the displacement of luxury cars is greater than 4.0L.
I've driven quite a few cars and found that 2.0L engines typically consume 10-20% more fuel than 1.5L ones. Specifically, a 1.5L car in the city averages about 6-8 liters per 100 kilometers, while a 2.0L might reach 7-10 liters, meaning an extra 1-2 liters per 100 kilometers. This varies with the car model—compact SUVs show smaller differences, while larger vehicles are more pronounced. Driving habits also play a big role; aggressive acceleration or using air conditioning can spike the 2.0L's fuel consumption faster. I recommend maintaining proper tire pressure and regular maintenance to save some fuel. On long highway trips, the gap narrows, with the 2.0L offering stronger performance, but for daily commutes, the 1.5L is more economical. Ultimately, test-driving several models is key—don’t just focus on engine displacement.
