What is the difference between a regular hybrid and a plug-in hybrid in the Audi A8?

I'm considering purchasing an Audi A8 but I'm not sure what the difference is between a regular hybrid and a plug-in hybrid. Can someone explain?

A regular hybrid operates on both gasoline and electric power, but the battery can only be charged through the car's regenerative braking system. On the other hand, a plug-in hybrid has a larger battery that can be charged using an external power source, allowing for longer electric-only driving.

A plug-in hybrid has a higher electric-only range compared to a regular hybrid, but it also has a higher price tag. Consider your driving habits and charging options before deciding which option is best for you.

A regular hybrid can switch between gasoline and electric power depending on driving conditions, while a plug-in hybrid can also be manually charged and driven solely on electric power for short distances. It ultimately depends on your daily driving needs.
