Why does the Audi A6 have a four-cylinder engine option?

I noticed that the Audi A6 has a V6 engine as the standard option, but there is also a four-cylinder available. Is there a specific reason for offering this engine choice in the A6 model?

The four-cylinder engine in the Audi A6 provides better fuel efficiency compared to the V6 option. So if you're looking for a more cost-effective and eco-friendly option, the four-cylinder could be a good choice.

By offering a four-cylinder engine in the Audi A6, the vehicle becomes more accessible to a wider range of buyers. This option may appeal to those who want the luxury and style of the A6, but may not necessarily need or want the power of a V6.

The four-cylinder engine in the A6 actually has comparable performance to the V6, thanks to turbocharging technology. It may not have the same raw power, but it offers a smooth and efficient driving experience.
