Porsche Cayenne has a total of 11 models on sale. Among them, the Cayenne-2023-Cayenne-3.0T, equipped with a 340-horsepower engine, has an NEDC fuel consumption of 8.9L per 100 km; the Cayenne-2023-Cayenne-S-2.9T, equipped with a 440-horsepower engine, has an NEDC fuel consumption of 9L per 100 km; the Cayenne-2023-Cayenne-Turbo-4.0T, equipped with a 549-horsepower engine, has an NEDC fuel consumption of 11.3L per 100 km. The fuel tank capacity of the Porsche Cayenne is 90L. The distance each model can travel on a full tank of fuel is as follows: For the model equipped with a 549-horsepower engine, the distance on a full tank is 90/11.3100=796km. For the model equipped with a 440-horsepower engine, the distance on a full tank is 90/9100=1000km. For the model equipped with a 340-horsepower engine, the distance on a full tank is 90/8.9*100=1011km. The powertrain of the Porsche Cayenne is equipped with 2.9T and 3.0T 6-cylinder twin-turbocharged engines as well as a 4.0T 8-cylinder twin-turbocharged engine, delivering outstanding performance. Particularly, the 4.0T 8-cylinder twin-turbocharged engine boasts a maximum output power of 404kw and a peak torque of up to 770N·m. Specific factors that can increase a car's fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, frequent overtaking, and not easing off the throttle before a red light, can increase fuel consumption. The car itself: Cars with larger engine displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean higher power, requiring more gasoline to burn and perform work. Heavier cars also consume more fuel because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind: Driving against the wind or on windy days increases car resistance and fuel consumption. Low environmental temperatures result in lower engine block temperatures. During cold starts, the injected gasoline is less likely to atomize, requiring more gasoline to be injected for combustion, thus increasing fuel consumption. Additionally, at low temperatures, the engine's computer may control higher idle speeds to warm up the car, which also increases fuel consumption. Insufficient or low tire pressure increases friction between the tires and the ground, leading to greater resistance and higher fuel consumption. Severely worn tires may frequently slip, also increasing fuel consumption. Poor-quality gasoline can lead to carbon buildup. Excessive carbon can roughen the intake pipe walls, affecting the intake effect and the quality of the air-fuel mixture, causing a sharp increase in fuel consumption.
