What does the blue logo Volvo mean?

[DerekFitz]

Blue logo Volvo refers to hybrid models. Below is a related introduction to the advantages and disadvantages of hybrid electric vehicles: Advantages: High fuel economy performance and superior driving performance. Hybrid electric vehicles use fuel for their engines, and with the assistance of electric motors during startup and acceleration, fuel consumption can be reduced. The internal combustion engine can be shut off, allowing the battery to drive alone, achieving "zero" emissions. Not fuel-efficient during prolonged high-speed or constant-speed driving. The fuel consumption advantage of hybrid vehicles mainly relies on potential energy accumulation for electric energy saving. Hybrid vehicles are more energy-efficient when frequently braking, decelerating, or starting and stopping. However, if driving at a constant speed for a long time, the energy-saving effect will be correspondingly reduced.
