How is a purely electric vehicle different from a vehicle with a combustion engine?

The combination you've selected accurately reflects essential differences between purely electric vehicles (EVs) and vehicles with combustion engines.

1. Lower engine noise: Electric vehicles are designed to operate more quietly compared to combustion engines. This is crucial in urban areas where noise pollution is a concern, and local regulations often promote quieter driving.

2. No direct exhaust emissions: Electric vehicles do not produce exhaust gases, which is significant in combating air pollution. According to German regulations aimed at reducing CO2 emissions and promoting cleaner air, this aspect is essential for environmental protection.

The third option, which pertains to aerodynamic drag, while potentially a factor in vehicle design, does not specifically differentiate electric vehicles from combustion engine vehicles within the context of German traffic rules, thus making it less relevant to the question. Selecting all applicable options is important to fully grasp the distinct characteristics defined in transportation regulations.
