The MIIT (Ministry of Industry and Information Technology) provides a reference fuel consumption figure of 7.9 liters per 100 kilometers for the CT6. However, actual fuel consumption may vary depending on driving conditions and individual driving habits. Below are some relevant introductions regarding fuel consumption: Avoid prolonged idling or low-speed driving: If the vehicle is idling in place, the engine is still running, and the fuel consumption per 100 kilometers will significantly increase. Moreover, under such stagnant or low-speed conditions, due to the relatively low engine speed, combustion within the engine cylinders is incomplete, which can easily lead to carbon buildup, further increasing fuel consumption. Therefore, avoiding prolonged idling and low-speed driving is crucial for reducing fuel consumption. Avoid excessive vehicle load and a full fuel tank: The more weight the vehicle carries, the higher the fuel consumption during driving. Therefore, it is advisable to minimize the vehicle's load. Additionally, when refueling, it is not necessary to fill the tank completely; filling it halfway can also help reduce the vehicle's weight. Avoid using high-viscosity engine oil: Under the same environmental conditions, using engine oils with different viscosities can result in different fuel consumption levels.

As an owner of a XT5, the fuel consumption is quite noticeable during city traffic jams, averaging around 15L/100km. However, it becomes much more economical on highways, dropping below 10L/100km. The main reasons are its tall and heavy body, coupled with a powerful engine that naturally consumes more fuel, but the comfort and safety systems are excellent. Newer models like the CT5 utilize turbocharging technology, which improves fuel efficiency, making daily commutes less of a burden, though filling up the tank does sting a bit. I recommend considering your driving habits when choosing a car; frequent long-distance trips will make it more cost-effective.

From a car enthusiast's perspective, Cadillac's fuel consumption really depends on the specific model. Smaller-displacement sedans like the CT4 are relatively fuel-efficient, averaging around 8 liters per 100km, while large SUVs like the Escalade can soar up to 20 liters. Modern models are equipped with efficient engines, such as twin-turbo systems that reduce waste, and driving gently without stomping on the accelerator helps. The brand is pushing forward with hybrid and electric technologies—the newly released LYRIQ doesn't consume any fuel at all. Technological upgrades have injected new vitality into this classic brand, making it significantly better than the pure gasoline era.

From an environmental perspective, Cadillac's urban fuel consumption is relatively high, with significant emissions affecting air quality, especially during prolonged idling in congested areas. The newer models now feature start-stop technology that automatically shuts off the engine, reducing waste. Overall, it's not as fuel-efficient as Japanese brands like , but transitioning to new energy options such as electric models achieves zero emissions. Opting for smaller vehicle models in cities is a greener choice.

Economically speaking, a Cadillac requires considering long-term fuel costs, which are significantly higher than a Honda Accord. A full tank runs about 500 km, resulting in higher monthly expenses. Vehicle size determines fuel consumption—the CT5 is average, but SUVs cost even more. Rising gas prices add pressure, so those on a tight budget might consider hybrid versions for better fuel efficiency and tax savings.

Cadillac's fuel consumption has undergone significant changes over time. In the early days, V8 engine models often consumed around 17 liters, but after 1990, the introduction of smaller displacement engines reduced this to about 10 liters. Nowadays, intelligent engine systems, like those in the CT6, have optimized efficiency, with urban driving consuming 9-12 liters. The latest electric models don't use any fuel at all, as technological advancements have made it easier for luxury cars to be energy-efficient.
