CT5's actual fuel consumption ranges from 7 to 10 liters. Below are the relevant details: The fuel consumption difference of CT5: The Cadillac CT5 shows a significant difference in fuel consumption between city and highway driving, with a combined fuel consumption of around 8-9L per 100 kilometers. When driving in the city, the fuel consumption definitely exceeds 10L, but on the highway, it drops to around 7L, which is roughly equivalent to the official fuel consumption figures. American cars tend to have higher fuel consumption: The Cadillac CT5 is an American car equipped with a 2.0T turbocharged engine, so its fuel consumption is relatively high. Based on current driving conditions, this car's fuel consumption is around 10L per 100 kilometers. Maintaining this level of fuel consumption is mainly due to a balanced mix of city and expressway driving. If driven entirely in the city, the fuel consumption would exceed 10L.

My Cadillac CT5's real-world fuel consumption is a bit high. In city traffic jams, it often surges to 12 liters per 100 kilometers, while on highways it's slightly better, around 9 liters, which is quite a gap from the official 7-liter claim. The reasons? Driving habits play a big role—like when I accelerate or brake sharply, fuel consumption spikes. Frequent stop-and-go in traffic and blasting the AC also don’t help. I regularly check tire pressure and keep it at the recommended level, which helps slightly, but overall, the experience is worth the higher fuel consumption because the powerful performance makes driving so enjoyable. Testing in different conditions shows urban areas are the thirstiest, averaging around 11 liters, while mixed commuting hovers just over 10 liters. Smooth gear shifts are key, and fuel-saving tips include avoiding sudden throttle inputs and planning routes to bypass congestion. In real-world driving, combined consumption ranges between 10 to 12 liters.

Having driven the CT5 for several years, I've found that the actual fuel consumption varies with driving habits and environment, typically fluctuating around 10 liters per 100 kilometers. The 2.0T turbocharged engine delivers ample power but is relatively fuel-thirsty; the official rating of 7 to 9 liters is based on ideal test conditions, while in real-world urban short-distance driving, it can reach 12 liters due to frequent idling at traffic lights. Transmission tuning also plays a role—smooth driving can reduce consumption to around 8 liters. Hot weather with air conditioning adds roughly 1 liter. Maintenance-wise, changing to fresh oil and filters has helped. Long-term data shows that 10 liters under combined conditions is normal, similar to peers. Fuel-efficient techniques include gentle acceleration and using cruise control—highway cruising yields the lowest consumption (approx. 7 liters), which is more practical than official figures.

My CT5's fuel consumption is around 10 liters per 100km in daily driving, rising to 12 liters during peak urban traffic jams, and dropping back to approximately 7 liters during highway cruising. Driving habits like sudden braking or aggressive acceleration immediately increase fuel consumption, with short-distance commutes averaging 11 liters being the norm. Air conditioning usage also adds to fuel consumption slightly. Regular maintenance can help stabilize it below 10 liters.
