I am looking to buy an Audi A6 but I am unsure of the difference between the 45 and 55 models. Can someone provide more information?

The main difference between the Audi A6 45 and 55 models is the engine size and power. The A6 45 has a 2.0L engine with 248 horsepower, while the A6 55 has a 3.0L engine with 335 horsepower. It ultimately depends on your driving needs and preferences.

Another difference to consider is the fuel efficiency. The A6 45 has a better fuel efficiency with an EPA estimated 25 mpg city and 34 mpg highway, while the A6 55 has an EPA estimated 22 mpg city and 29 mpg highway. You should factor in your daily commute and driving habits when making a decision.

The A6 55 also comes with a standard adaptive suspension and all-wheel drive, providing a smoother ride and better handling in various road conditions. If you prioritize performance and handling, the A6 55 may be the better option for you.
