My C-Max SEL is now 11 days old, and I've broken it in on one of my few annual road trips, along with the city driving that will make up much more of this car's mileage. My trip to work couldn't be more stop-and-go, with over 30 traffic lights on my 7 mile commute. I've made 6 of these trips so far. This weekend's trip was totally different, about 900 miles of interstate driving through the rolling hills of New England and Pennsylvania. Pretty much none of this driving was done after the 1000 mile break-in period, but if it only gets better from here, I'm feeling very good about the new C-Max, my first hybrid car. Driving was fun and easy. I'm so impressed by the way it handles, the acceleration when I need it, and the comfort of the AC, heated seats (yes, I used them both), bluetooth audio, rain-sensitive wipers, and most of all the gas mileage. I used the ECO cruise control about 75% of the time, and tried hard to keep the speed between 60 and 65. I managed to cruise on EV about 20% of the time. Going up hills or pulling out to pass the (few) people driving slower than me, I noticed EV assisting the ICE quite often. It's a challenge to grow efficiency leaves. Boosting the MPGs definitely overtook the impulse to drive 80 in the fast lane, which I admit I'm pretty used to doing. It was a little painful to live in the slow lane, but I do have to say it was less stressful when I had a clear road in front of me for most of the trip. Near the end i upped the cruise control to around 69 and it did cost me about 0.2 mpg before long, but I was actually pretty impressed by how well the mileage held up at higher speeds. I'm looking forward to the hybrid re-programming to see if I can get better MPGs at higher speeds when the EV can still kick in while you're driving 75. It was interesting to look at the fuel efficiency coach, which gave me yellow bars on cruising whenever I used cruise control. On my own, I got much better graph results, although it didn't actually produce dramatically higher mileage. There is a lot more to learn. But I'm totally scratching my head over the "experts" who find it so completely impossible to get more than 37 MPG out of this car. I don't think I could have gotten mileage that low if I tried. Let's see if I got all this attachment stuff to work right!
