Which is More Fuel-Efficient, 1.2T or 1.5T?
1 Answers
Under the premise of the same car brand, the 1.2-liter engine is inevitably more fuel-efficient. Both being turbocharged engines, a smaller displacement and lower power naturally result in lower fuel consumption. A larger displacement means the engine releases more energy and operates more efficiently per unit of time. The greater the power, the higher the fuel consumption. More details are as follows: 1. To compare the fuel efficiency, power, or performance of engines, it must be done under the same technical level, and there are significant differences in engine technology among different brands. Fuel efficiency and performance are inherently opposing factors, which is something car owners need to weigh carefully. Generally, a larger displacement means greater power and stronger performance, but fuel consumption mainly depends on the output power, which essentially reflects the fuel injection volume. 2. Generally, the larger the displacement, the higher the fuel consumption. However, there is no direct conversion formula between the two because many factors affect fuel consumption, many of which cannot be quantified. Factors influencing fuel consumption are numerous, not limited to the engine's powertrain but also include the transmission, drag coefficient, vehicle weight, and tires. Additionally, driving habits, vehicle condition, and road conditions play crucial roles.
