You are driving a car with a plug-in hybrid drive system. How can you optimise fuel consumption?

The correct combination of answers highlights two key practices for optimising fuel consumption in a plug-in hybrid vehicle. Regularly charging the battery using the mains supply allows you to maximise the use of electric power, which is generally more fuel efficient than relying solely on the internal combustion engine. Furthermore, using the electric drive through your driving style helps to save fuel and reduce emissions, as you can take advantage of the electric motor's efficiency in low-speed scenarios and urban driving.

The third option, focusing only on recuperation, is not sufficient on its own because relying solely on this method may not provide enough energy for optimal vehicle performance. Recuperation is beneficial for charging the battery during driving but should be complemented by regular charging. According to German traffic regulations, efficient driving practices not only benefit the driver economically but also contribute to environmental protection, aligning with the country's goals for reducing emissions and promoting sustainability. Understanding these strategies ensures you drive responsibly and in accordance with both legal obligations and best practices.
