When you said the Vibe mpg while towing 1500 pounds is 25mpg, you revealed one key to your lower mpgs with the C-MAX.
The Vibe weighs about 2700 pounds.
The C-MAX Hybrid weighs about 3600 pounds.
So compare your C-MAX results when towing 900 pounds with your Vibe.
I own a 2003 Vibe base automatic.
We're retired now and live in a small suburban town in the Indianapolis area, so we drive lots of short local trips, year round, often 2 miles or less. In the Vibe, I get 16-19mpg in the winter including a few minutes of warm-up time, always at 0mpg, on short local trips, versus about 30 mpg for mostly interstate driving.
Year round, we average about 26mpg in our Vibe, lower in winter, higher in summer.
Link to the last several years of Fuelly data for our Vibe:
Year round, we average a bit above 40mpg in our C-MAX, lower in winter, higher in summer.
Link to Fuelly data since purchase for our 2013 C-MAX Hybrid SE:
With your driving patterns, a Toyota Prius or Prius V hybrid wagon, or C-MAX Energi plug-in Hybrid MIGHT have been a better choice for you purely based on fuel mileage. This is a C-MAX Forum, so I'll let you research the Prius and Prius V hybrid wagons on your own.
The C-MAX Energi Hybrid can be pre-heated or pre-cooled while attached to an electrical outlet (a feature not offered on the C-MAX Hybrid SE or Hybrid SEL). The up-to-20-mile maximum range in full-electric mode of an Energi Hybrid might cover most of your trips on one charge per day. The major disadvantage of the Energi is the larger battery, so greater weight (3900 vs 3600 pounds), and a higher rear 'floor' over the larger battery, resulting in decreased storage in the rear of the car.
