What is the fuel consumption difference between 1.5L and 1.8L engines?
2 Answers
1.5L engines consume 6 to 7.5 liters per 100 kilometers, while 1.8L engines consume approximately 7 to 9.5 liters per 100 kilometers. Below is relevant information: 1. Calculation method: The actual method to calculate fuel consumption per 100 kilometers is: X/100=50/600, where X is the actual fuel consumption per 100 kilometers being sought, and the right side of the equation represents 50 liters of fuel consumed over 600 kilometers of driving. 2. Fuel consumption per 100 kilometers: This refers to the amount of fuel a vehicle consumes when driving 100 kilometers on the road at a certain speed. It is a theoretical indicator for vehicles. The fuel consumption per 100 kilometers is a value measured by manufacturers under objective conditions using a dynamometer installed on the vehicle's chassis, converted into speed parameters, and then calculated as the theoretical experimental fuel consumption data for the vehicle model when driven at specified speeds.
As a frequent car modification enthusiast, I find the fuel consumption difference between 1.5L and 1.8L engines quite noticeable. Generally, a 1.5L car consumes 5-7 liters per 100km, while a 1.8L might use 7-9 liters, with about 1L difference being common. For example, if you drive 50km daily, the 1.8L could burn 30L more fuel per month. At current fuel prices of 8 yuan/L, that's 240 yuan extra. This difference comes from larger displacement drawing more air, resulting in more intense combustion but lower efficiency. From my experience with different cars, smaller engines are more economical for urban commuting, especially in traffic with lighter acceleration. Heavier vehicles might feel more stable with bigger engines but consume more fuel. Also consider technology - some 1.5T turbocharged models match older 1.8L engines in fuel efficiency. When choosing, consider your habits: frequent long-distance drivers might prefer 1.8L for comfort, but 1.5L saves money. Remember regular maintenance of air filters and spark plugs, as they affect fuel economy too.
