Thank you for all of the feedback! My Fusion has been like this since I bought it CPO and I admittedly just assumed it was a result of being differently sized vehicles (wheel base, slight weight difference, aerodynamics, slightly different tires/rims). I only recently started doing some research which prompted me to look into this more. I'll see if I can rope a dealership into look at it before my warranty is up; I'm sure they'll push this off an a non-issue hahaha

In 2019, my wife and I bought a used 2017 C-Max Energi Titanium (10K miles at purchase). Thrilled with everything about the C-Max, except the style, I bought a CPO 2017 Fusion Energi Titanium (35K miles at purchase) in 2020 thinking I'd experience better fuel economy and an improved driving experience. After two years of driving both, I'm experiencing the following (C-Max currently at 30K miles, Fusion currently at 60K miles). My wife was teaching remotely so I have been switching cars every other week so I could keep both moving. Fuel Economy (only gas; pure electric hasn't been an issue) Fusion 34-35 MPG combined (5 day/week 30 mile daily commute, 10 miles local roads and 20 miles 65 MPH highway) 36 MPG highway (100+ mile highway only road trips) C-Max 42-45 MPG combined (5 day/week 30 mile daily commute, 10 miles local roads and 20 miles 65 MPH highway) 41 MPH highway (100+ mile highway only road trips) The C-Max is significantly peppier on both gas and electric, even with the better fuel economy. The Fusion feels sluggish compared to the C-Max, as if the Fusion was holding a bunch of extra weight. Not fuel related, but C-Max is significantly more comfortable to drive. My head touches the roof in my Fusion while I have several inches above my head in the C-Max. I joke with my wife that my vanity cost me an extra $6K and lost me headroom, MPGs, and peppiness to get a Fusion instead of another C-Max. Assumptions: I accelerate similarly in both vehicles and drive at a similar speed during the commutes, I use ECO cruise control on longer highway trips, stock rims/tires (17" on C-Max, 18" on Fusion), unleaded standard gas, fuel injector cleaner every other fill up, Fusion has heated steering wheel and cooled seats which I don't use, C-Max has CEL due to a bad O2 sensor, full service synthetic oil changes from Ford dealership, plugged in and charged every 3-4 days due to having a small driveway. I still love my Fusion Energi, but I'm hoping someone can help me bridge the MPG and peppiness gas between my Fusion and my wife's C-Max. I thought they were on the same powertrain, but I may be mistaken. Any advice is appreciated. Thank you!
