Drove a 2018 CMAX Hybrid Titanium to compare to my 2013 SEL, mainly interested in MPG's and handling/ride feel. I wanted to make a close comparison so I managed to talk the salesman into raising tire pressure to 50 psi, taping on my center and lower Grill Covers. Went on a 8 mile city driving trip and only managed 41.9 mpg, a little disappointed to say the least. So I tried to figure out why, here are some potential problems. The car only had 50 miles on it, we were using Regular, trip was mainly going up and down hills for 8 miles. I'm thinking the ECM takes some miles to learn how to drive efficiently and the car wasn't aggressively trying to go into EV, accelerator was very sensitive about dropping out of EV as compared to my car. Things that should made it do better, temps were 73*F, installed Grill Covers which got WT upto 207*F in 6 miles which is very good, 50 psi tire pressure.
By comparison I drove a 2017 CMAX Hybrid Titanium under less favorable conditions and got 46+mpg going 20 miles without Grill Covers and 50psi tire pressure. The car did have 250 miles on it.
