How much fuel does a 336 horsepower engine consume at idle for one hour?

[DeLeonardo]

336 horsepower consumes 1-2 liters of fuel per hour at idle. Here is detailed information about vehicle fuel consumption per 100 kilometers: 1. Overview: Fuel consumption per 100 kilometers refers to the amount of fuel consumed when a vehicle travels 100 kilometers on the road at a certain speed. It is a theoretical indicator for vehicles. Manufacturers measure this value using a dynamometer installed on the vehicle chassis under objective conditions, convert it into speed parameters, and then calculate 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 90 km/h, the officially published theoretical fuel consumption is usually the fuel consumption per 100 kilometers at 90 km/h.
