What are the main differences between the Audi A6 standard model and the Audi A6 Premium Plus model?

I am looking to buy an Audi A6 and I am torn between the standard model and the Premium Plus model. Could you please explain the technical specifications and features that distinguish the standard model from the Premium Plus model?

The Audi A6 Premium Plus model comes with a 2.0-liter TFSI turbocharged four-cylinder engine, while the standard model has a 3.0-liter TFSI V6 engine. This results in a difference of 80 horsepower, with the Premium Plus model producing 248 horsepower and the standard model producing 328 horsepower. Additionally, the Premium Plus model has a larger fuel tank capacity of 19.3 gallons compared to the standard model's 18.5 gallons.

One of the main differences between the standard and Premium Plus models is in terms of safety features. The Premium Plus model comes standard with Audi pre sense rear and Audi side assist for increased visibility and awareness while driving. These features are only available as optional upgrades in the standard model. Furthermore, the Premium Plus model also comes with a top view camera system for enhanced parking assistance.
