Why is the fuel consumption of the Buick Excelle XT 16T considered unbearable?

[StDiana]

Buick Excelle XT 16T has high fuel consumption. The reasons are as follows: 1. The car is heavy, nearly 1.5 tons, slightly heavier than its peers. 2. The tires are wide, reaching 225mm, which is also among the top in its class. Compared to similar models, this to some extent leads to higher fuel consumption. 3. The transmission and engine are not well matched, and the transmission efficiency is not very high. 4. The engine itself lacks new technology support such as direct fuel injection. Additional information: Methods to reduce fuel consumption are as follows: 1. Check the air conditioning system in summer. Air conditioning failure may also be an important reason for high fuel consumption. If the air conditioning cooling effect is not good, many people will increase the fan speed and lower the temperature to achieve a cooling effect. 2. Frequent sudden braking is the main cause of high fuel consumption. Data from hybrid models with kinetic energy storage show that their fuel consumption is about 40% lower than that of similar models. This side data also reflects that the comprehensive fuel consumption in urban areas is high, which is obviously related to frequent sudden braking.
