Took my first road trip in my V8 RRS. I thought for sure fuel economy would be worse. I made it from Syracuse NY all the way to NYC and back on one tank of fuel ~500 miles). Still had 15 miles to spare according to the car. I averaged 24.2 mpg over the entire trip. This seemed a bit high. For the majority of the trip, I had the cruise control set to 79 mph. Needless to say, I was very happy. This car is amazing on long trips. Great music, very comfortable and to my surprise, reasonable fuel economy (my 328i only achieved 26 mpg highway). I love this vehicle! I just hope it loves me back enough not to develop “problems”.
