What is the fuel consumption of the new Jetta with air conditioning on in summer?

[LaWalter]

The new Jetta's fuel consumption with air conditioning on in summer increases by about 2 liters. Fuel consumption with air conditioning on in summer: The operation of the air conditioning consumes engine power, not only increasing fuel consumption but also making the car feel 'underpowered.' Typically, the car's air conditioning accounts for about 20% of the engine's power. For example, a car that normally consumes 10 liters per 100 kilometers will see an increase of about 2 liters in fuel consumption with the air conditioning on. This shows that the impact of air conditioning on fuel consumption is quite significant. Why does using air conditioning consume more fuel: After turning on the AC button, the air conditioning compressor needs to work to cool, and the car's air conditioning compressor is directly driven by the engine, consuming part of the engine's power, which in turn consumes fuel. The amount of fuel consumed by the air conditioning largely depends on the type of compressor the car uses.
