Group, I just purchased a 2017 FWD Limited with a 250 mile, 5 day Money Back Guarantee. After filling the tank, I drove 100 city miles - no bumper to bumper rush hour or highway - just the usual, flat land, Houston traffic with the AC on - same as my FWD, 4 cyl 2007 we got 239K out of. After refilling 6 gallons of gas, the math returns just 16.6 MPG city. I've topped off and will do another 100 tomorrow but this is very low MPG and concerning as I have to decide to keep or return within the next 2 days/150 miles. Any input would be much appreciated - are the 13-18 gen FWD models known for lower than posted 23/29? Thanks.
