What is the fuel consumption difference between 1.5 and 2.0 engines?
2 Answers
The fuel consumption difference between 1.5L and 2.0L engines is approximately 2.5 liters per 100 kilometers. Here is relevant information about engine displacement: 1. Cylinder working volume: Displacement refers to exhaust volume. Cylinder working volume means the volume swept by the piston moving from top dead center to bottom dead center, also called single-cylinder displacement, which depends on cylinder bore and piston stroke. Engine displacement is the sum of all cylinders' working volumes, generally expressed in liters (L). 2. Displacement classification: Mini cars have displacement ≤1.0L; Compact cars range from 1.0-1.6L; Mid-size cars range from 1.6-2.5L; Executive cars range from 2.5-4.0L; Luxury cars have displacement >4.0L.
I've driven a 1.5L car and a 2.0L SUV, and the difference in fuel consumption is quite noticeable. The 1.5L one averages around 7.5L/100km in city driving, dropping to 6.5L on highways. In contrast, the 2.0L vehicle reaches 10L/100km in the city and 8.5L on highways, resulting in a difference of 2 to 3 liters per 100 kilometers. Over a year, driving 10,000 kilometers, this can amount to a difference of over 200 liters of fuel, saving around a thousand yuan in fuel costs. Several factors influence this, such as the 2.0L consuming more fuel in traffic jams—it accelerates faster but burns more fuel. In cold weather, fuel consumption increases slightly for both. I recommend checking the official data for different models, but real-world tests are more important. Personally, I now opt for a smaller car for peace of mind and cost savings.
