What is the fuel consumption of the Porsche 911?
2 Answers
The fuel consumption of the Porsche 911 is approximately 10.2L/100km. The following are factors that affect a car's fuel consumption: 1. Thermal efficiency of the engine: From a purely technical perspective, direct fuel injection is an excellent technology that significantly improves fuel combustion efficiency, but it places higher demands on the engine's fuel supply system and cylinder materials. 2. Resistance encountered by the car: (1) Gradient resistance: When a car is driven on an inclined road surface, the component of its gravity along the road direction manifests as gradient resistance. Clearly, this is mainly related to the weight of the car. The heavier the car and the steeper the slope, the greater the force needed to overcome, and the higher the car's fuel consumption. (2) Acceleration resistance: When a car accelerates, there is an inertial force present, which constitutes the car's acceleration resistance. According to the momentum theorem, the greater the car's mass and the larger the acceleration, the greater the resistance.
The fuel consumption of the Porsche 911 is not fixed and depends on the specific model you drive. For example, the standard Carrera has a combined fuel consumption of around 10 liters per 100 kilometers, while the Turbo S may reach 12 to 15 liters. The engine is a horizontally opposed six-cylinder, designed for efficiency, but if you engage sport mode or frequently accelerate aggressively, fuel consumption can spike. In city driving with frequent stops and traffic jams, consumption may rise above 12 liters; on the highway, it drops significantly to 8-9 liters. Driving habits play a big role—I drive my 911 gently and maintain an average of around 10 liters, but a friend with the same model who enjoys speeding often sees 13 liters. Don’t forget to regularly check tire pressure and engine oil, as this can slightly reduce consumption. Compared to other sports cars, the 911 is relatively economical.
