What are the reasons for the high fuel consumption of the old Cruze?

[OJosie]

GM cars themselves are fuel-intensive because the body weight is much heavier than cars in the same price range. Additionally, the Cruze's transmission program is a product independently developed by Pan Asia, featuring a unique fuel injection method. It also includes an anti-piercing system, the so-called safety system, which makes the car sluggish at startup. As the car ages, factors such as throttle body wear, catalytic converter degradation, fuel line aging, and carbon buildup in the fuel injectors all contribute to increased fuel consumption. More details about the Cruze are as follows: 1. Excellent performance: The new Cruze integrates very advanced technology, featuring a rugged and dynamic exterior and a youthful, stylish interior. It has relatively low fuel consumption and leading performance among A-segment cars. 2. Suitable displacement: The Cruze currently comes in two displacements, 1.6 and 1.8, with a total of six models. The dimensions are 4598x1797x1477mm. 3. Compact sedan: The Cruze is a compact sedan developed by GM using a global design platform and made its global debut at the Paris Motor Show.
