The official combined fuel consumption of the CT6 is 7.1 liters per 100 kilometers, while the constant-speed fuel consumption refers to the vehicle's fuel consumption per 100 kilometers obtained in constant-speed driving fuel consumption tests specified by national standards for certain types of vehicles. The fuel consumption per 100 kilometers of a car is not fixed and can be affected by various factors such as road conditions, load, temperature, and whether the air conditioning is on. Taking the CT6 2021 28T Fashion model as an example, it is a mid-to-large-sized car under SAIC General Motors Cadillac. In terms of the suspension system, the front suspension type is a double-wishbone independent suspension, and the rear suspension type is a multi-link independent suspension, with electric power steering. Regarding body dimensions, the car measures 5223 mm in length, 1879 mm in width, and 1492 mm in height, and it is a 4-door, 5-seater sedan.

I've been driving a CT6 for several years, and fuel consumption really depends on the specific situation. During rush hour traffic in the city, it's around 12 to 15 liters per 100 kilometers, while cruising on the highway is more economical, roughly 8 to 10 liters. The car's large size and heavy weight naturally lead to higher fuel consumption. I usually drive gently, avoiding sudden acceleration or braking, keeping the fuel consumption around 11 liters. Seasonal effects are also significant; using air conditioning in summer adds 1 to 2 liters, and warming up the engine in winter also consumes a bit more fuel. I recommend regularly checking the engine oil and tire pressure to maintain optimal conditions for fuel efficiency. Avoiding short trips with a cold engine and opting for longer drives can improve efficiency—these small tips can help reduce fuel consumption.

I'm very interested in automotive technology. The fuel consumption of the CT6 varies depending on the engine version. The 2.0T turbocharged model has a combined fuel consumption of approximately 10 to 11 liters per 100 kilometers, while the 3.0T V6 version is slightly higher, around 12 to 13 liters. Modern technologies like automatic start-stop and efficient drivetrains optimize fuel efficiency; using adaptive cruise control on highways can further save fuel. Smooth driving is crucial, as aggressive driving can cause fuel consumption to surge above 15 liters. is also important; ensuring the intake system is clean and the spark plugs are functioning properly is essential, otherwise efficiency will be compromised. City traffic congestion is a major fuel consumption killer, so it's advisable to avoid peak hours whenever possible.

I use my CT6 for picking up kids and shopping, with an average fuel consumption of around 11 to 14 liters. In city traffic jams, it's noticeably more fuel-consuming, easily exceeding 12 liters; while on highways during family trips, it's more economical, around 9 to 10 liters. For a large car, this fuel consumption is reasonable; compared to its peers, it doesn't have a significant advantage. In daily use, I've noticed that a fully loaded back seat or using the air conditioning adds to the burden, increasing fuel consumption to around 13 liters. Regular oil changes help stabilize fuel consumption, and a dirty air filter also affects it. A practical tip is to plan routes in advance to avoid congested roads, making the drive more economical and comfortable.

From an environmental perspective, the CT6 has relatively high fuel consumption, averaging 10 to 13 liters per 100 kilometers, which equates to high carbon emissions; driving this car emits nearly 2 kilograms of CO2 every 10 kilometers. Currently, pure electric vehicles can achieve lower emissions, but the CT6 is designed as a fuel-powered vehicle. Maintaining a steady speed while driving and reducing frequent stops and starts can lower fuel consumption to the minimum of 10 liters per 100 kilometers. Avoid short trips with high energy consumption; for example, a cold start followed by just a few kilometers of driving can cause fuel consumption to spike to around 15 liters per 100 kilometers. For city driving, choose non-peak traffic hours, and for long distances, use the economy mode to save resources. This car has strong power, but its energy efficiency needs improvement. Protecting the environment starts with individual driving habits.

I've been driving the CT6 for nearly a year, maintaining an average fuel consumption of 11 liters per 100 kilometers. In actual usage, urban commuting consumes over 12 liters, while highway trips average around 9 liters. I prefer using premium gasoline, as it makes the engine run smoother and slightly reduces fuel consumption. For , I change the oil and filters on schedule to ensure the system operates efficiently. Driving habits are crucial; avoiding idling and speeding can save fuel. I've tested several times that gentle acceleration to highway speeds stabilizes fuel consumption at 10 liters. Weather changes also affect it; using air conditioning in high temperatures easily increases consumption by 1 liter. My personal tip is not to let the fuel tank run empty often; filling up for long-distance trips is more economical.
