 Don't be put off by the negative reviews.The C-MAX really does get the advertised mileage. It's a very comfortable ride and fun to drive.The car has about 4500 miles on it, and I'm getting 52-53 MPG.The mileage does improve over the first 3000 miles!At 1000 miles the MPG was 43-44, at 2000 miles it was 46-47, and at 3000 miles it 49-50.If you follow the recommendations in the manual you should get the advertised 47 MPG:go gradually on the acceleration and stay around the speed limit.The key for good MPGs is to maximize travel in EV mode. Heavy acceleration and speeding keeps the hybrid in gas engine mode, and the MPGs drops rapidly:back off the accelerator to stay in EV mode.
