I purchased my 2016 Fusion Hybrid S Nov 12, 2015 and was told not to expect 44 mpg until about 2000 miles. I've been pleased to get consistently 42-43 MPG since the purchase. The last tankful (about 1,500 miles) I reset the trip settings and got 43.8 on that tankful. I filled the tank at 1,999 miles and was surprised at the immediate mileage increase of about 4%. Don't get me wrong, I love the increase. I just wondered if there's a break-in algorithm embedded in the control unit which defaults to normal at mile 2,000 generating improvements the salesman spoke of and I'm experiencing???? I probably would not have noticed the interesting change had I not run the tank nearly empty to coincide with the 2,000 mile benchmark. Just wondering...but enjoying it. Much better on fuel costs than the 2001 Pontiac TA WS6 I sold which required premium fuel. ;) I'm enjoying this Fusion so far.
