How much fuel does a 460-horsepower engine consume at idle for one hour?
2 Answers
460-horsepower engine consumes eight liters of fuel per hour at idle. The fuel consumption of a car varies slightly depending on each driver's habits and skills. A smoother driving style results in lower fuel consumption, while aggressive driving habits such as frequent high-revving operations like overtaking will appropriately increase fuel consumption. Below are some methods to reduce fuel consumption: 1. Check the air conditioning system in summer: Air conditioning malfunctions are a major cause of high fuel consumption. If the cooling effect is poor, the fan speed will increase, and the temperature will be lowered to achieve a cooling effect. 2. Frequent hard braking: Frequent hard braking is a primary reason for high fuel consumption. While ensuring safe driving, make full use of the vehicle's inertia. 3. Avoid excessive use of air conditioning in small-displacement cars: For vehicles exposed to the sun, do not turn on the air conditioning immediately after getting in. First, open the windows and set the fan to a higher speed without turning on the air conditioning to expel the hot air inside. After the car has cooled down moderately, then turn on the air conditioning.
As someone who has driven high-performance cars for years, I can tell you that a 460-horsepower engine idling for an hour typically consumes between 1.5 to 3 liters of fuel, depending on the car's brand and condition. For example, a large-displacement V8 engine, while idling at low RPMs, is not efficient, averaging 0.03 to 0.05 liters per minute, which easily adds up to 2 liters burned in an hour. I've seen older sports cars consume over 3 liters per hour during summer idling, mainly because the engine needs to maintain cooling and electronic system operation. Cars with larger displacements and older models are more fuel-consuming at idle, so avoid prolonged idling—it's both a waste of money and harmful to the engine. It's better to park in the shade or simply turn off the engine. Long-term idling also leads to carbon buildup, increasing maintenance costs.
