4.0 engine fuel consumption is generally above 15 liters. Reasons for high fuel consumption in 4.0 engines: The 4.0 displacement is relatively large, so the fuel consumption is correspondingly high. For example, Audi's 4.0T engine features cylinder deactivation technology. Although it has a 4.0 displacement, it doesn't operate at full 4.0 capacity during actual use, and the fuel consumption is generally around 15 liters. Factors affecting fuel consumption: Driver's driving habits, road conditions, weight of items placed in the car, whether the air conditioning is on, and whether the vehicle is in the break-in period, among other factors, can all affect the vehicle's fuel consumption.

As a friend who has driven similar cars, I have to say that a 4.0-liter engine typically consumes around 0.12 to 0.18 liters of fuel per kilometer, depending on the car model and driving habits. In heavy city traffic, fuel consumption can exceed 0.16 liters per kilometer due to frequent stops and starts, which burn more fuel. On the highway, maintaining a steady speed can reduce it to 0.12 liters. I remember driving a 4.0T SUV last time—it was heavy, and with extra luggage, it consumed about 0.17 liters per kilometer. Over a month, the fuel cost was about 300-400 yuan more than a smaller-displacement car. Regular maintenance is recommended, such as checking tire pressure and engine condition, to save some fuel. Don’t overlook driving habits: aggressive acceleration and using air conditioning can make the fuel gauge drop faster.

If you're a performance enthusiast, a 4.0T car typically consumes 0.13 to 0.16 liters per kilometer, equivalent to 13 to 16 liters per 100 kilometers. When I drive such cars, the roaring engine is truly exhilarating, and climbing slopes feels effortless, but the fuel consumption is astonishingly high. Turbocharging can improve efficiency, but with heavy vehicles like SUVs, fuel consumption can soar to 0.18 liters per kilometer. Adding lightweight components during modifications might help a bit, but don't expect to save money. Driving steadily in daily use, such as maintaining a constant speed of 60 km/h, will make the fuel gauge less intimidating. It's best to keep a log and calculate the distance traveled per refuel to adjust accordingly.

Simply put, a 4.0-liter displacement car consumes approximately 0.14 liters of fuel per kilometer. This figure is just an average, and actual consumption varies. In congested city driving, it can rise to 0.17 liters; on smooth highways, it drops to around 0.12 liters. Personal experience: the car's age and maintenance condition significantly impact fuel efficiency. Older cars may consume more, but regular oil changes can help reduce it slightly. Don't just calculate fuel costs—consider insurance and maintenance fees too. If you frequently drive long distances, compare more car model data before making a choice.
