What are the differences between the Audi A6 diesel and petrol engines?

I am considering purchasing an Audi A6 and I am unsure whether to go for the diesel or petrol engine. Could you provide some insight on the key differences between these two engine types, in terms of performance, maintenance and fuel efficiency? Thank you.

Both diesel and petrol engines have their pros and cons. Diesel engines typically offer better fuel efficiency and torque, while petrol engines tend to have higher horsepower and smoother acceleration. As for maintenance, diesel engines require more frequent oil changes and may have higher repair costs. Ultimately, it depends on your driving habits and priorities.

In my experience, diesel engines are better for long distance driving and highway cruising, while petrol engines are more suitable for city driving and short trips. Consider your typical usage and choose accordingly.

If you are concerned about environmental impact, keep in mind that diesel engines emit more pollutants than petrol engines. This may not be a significant factor in your decision, but it's worth considering.
