Modern cars have a multitude of peripheral systems that significantly assist drivers, making driving safer and easier.
However, it is a given that the operation of all these burdens the engine and increases fuel consumption.
So, while seemingly one switch won’t wreak havoc on your pocket, the combination of all of these increases the vehicle’s fuel demands quite a bit, causing the tank to empty faster than you might have expected.
Electrical systems, such as heated seats or the audio system, increase fuel consumption
One of the most characteristic examples of energy burden in the car is the air conditioning system of the cabin. Usually its operation increases fuel consumption by 0.5 to 1 liter/hour.
At the same time, systems that burden fuel consumption are also the subsystems of the vehicle that consume electricity, such as the sound system, the use of charging ports, heated seats or the lighting system.
The increase in fuel consumption is estimated at 0.1 litres/100 km for a consumption of 100 Watts of energy, while the use of the heated rear windscreen alone can cost us 0.8 liters of fuel per 100 kilometres.
For this reason, a driver should think twice about activating the vehicle’s lights, heated windshield, air conditioning and audio system together.
