I just bought a 2016 Mini 4 door hard top. Automatic transmission.. Had for 2 weeks. It was a loaner car at dealership. Had 1,020 miles on it. Got a great deal!

I was under the impression from all I have read that they got great gas mileage. I have only been getting 20mpg?!?! It is a hot time of year and I know that can use extra gas. And driving speed. I do have a somewhat heavy foot. But I'm not racing around!
Called the dealership and they said to put in green mode?! Uh I did the buy the car to drive like my grandpa! I expected to get at least 23 to 25 mpgs.

What is everyone else getting for mpg?
Thanks!!
