How much fuel does a 550-horsepower car consume when idling for one hour?

[VanCaden]

A 550-horsepower car consumes approximately 12 liters of fuel when idling for one hour. Below is a detailed introduction about a car's fuel consumption per 100 kilometers: 1. Overview: Fuel consumption per 100 kilometers refers to the amount of fuel a vehicle consumes when driving at a certain speed for 100 kilometers on the road. It is a theoretical indicator for the vehicle. The fuel consumption per 100 kilometers is measured by manufacturers under controlled conditions using a dynamometer installed on the vehicle's chassis, converting the obtained values into speed parameters, and then calculating the theoretical experimental fuel consumption data per 100 kilometers for the model at specified speeds. 2. Others: Since most vehicles approach their most economical speed at around 90 km/h, the theoretical fuel consumption figures publicly released are usually based on the fuel consumption per 100 kilometers at 90 km/h.
