I got a 2023 turbo CX5 top of line. They advertised the average mpg is between 24 city 27 highway. I drive to work everyday and the route is 95% highway, average speed of 55mph and I’m hitting on average 21.5 mpg within 8,700 miles.

Does anyone else have the same issue? Or would y’all say I have a faulty car? Tks
