What are the most important safety features in the Audi A6?

I'm planning to buy a new car and safety is my top priority. I've heard that Audi A6 is a pretty safe car, but what specific features should I look out for?

The Audi A6 comes with a host of advanced safety features, but the most important one to look out for is the Audi Pre Sense system. It uses sensors and cameras to detect potential collisions and can automatically apply the brakes to avoid or mitigate the impact.
