What are the different battery options available in the Audi A4?

Can you provide more information about the various battery options and their specifications for the Audi A4?

The 2019 Audi A4 offers three different battery options: a standard 12-volt battery, a 48-volt mild hybrid system, and a plug-in hybrid system.

If you want a more fuel-efficient option, the 48-volt mild hybrid system is a good choice. It allows the car to coast with the engine off in certain situations, reducing fuel consumption and emissions.

For increased range and reduced emissions, the plug-in hybrid system is the best option. It can travel up to 31 miles on electric power alone, and can be plugged in to recharge.
