How reliable is the Volkswagen Passat fuel efficiency?

I'm considering buying a Volkswagen Passat, but I'm concerned about the reported fuel efficiency. Can I trust the numbers provided by the manufacturer?

I have been using my Passat for a year now and I can say that the fuel efficiency is accurate. I constantly track my mileage and the numbers match up.

I had issues with my Passat's fuel efficiency at first, but after taking it to the dealership for a check-up, they fixed the problem and now I'm getting the expected mileage.

I've owned multiple Passats and they have all had great fuel efficiency. Just make sure to keep up with regular maintenance and you shouldn't have any issues.
