Just took my 1st long distant trip with the Cadenza, from Huntsville Al to Houston Tx... 1580 miles round avg mpg 31.2 while driving between 70- 75 mph. I also got an avg. of 27.8 while driving through traffic on I45 and 610 and the beltway. I must say I was very impress with these numbers and the way the car handled. As a personal rule when traveling long distant, I don't allow my tank to get past half a tank.
