Hehe I just have this on the back of my C-MAX Works like a charm :)

I have about 1500 miles so far on my SE that I've had since the middle of October. I've been hypermiling for the last six years. A couple of quick things I've noticed (not specifically relating to hypermiling) The manual indicates that the car's break-in period is technically "2000 miles–3000 miles (3200 kilometers–4800 kilometers)", so I think most of us experiencing lower-than-advertised fuel economy are still in this bracket With regard to highway driving, the engine will turn on and off at speeds up to 62 MPH (as reported by my ScanGuage, 65 MPH as reported by speedometer) as long as I keep the heat either off or around 65° - 69° F. Above 62 MPH, if you keep your Info Display on Engage (showing split power output), you can see that the EV motor turns on (at least when using cruise control) to assist when climbing hills and then recharges the battery going downhill This behavior with motor assisting on uphill and charging on downhill sees higher, consistent MPG (versus the drop to around 18 or so MPG at 62 MPH when climbing a hill and recharging the battery) I've noticed if I stay at 63 MPH (66 per the speedometer), it is just fast enough to keep the engine running the whole time and letting the EV motor still assist when climbing hills The EV motor seems to be able to provide the most assistance when climbing hills at 63 MPH (since this is just above the speed-threshold where the EV motor would stay on anyway) than at 70 MPH (where the motor hardly provides any assistance) [*]When the weather was warmer (65°F) a little while back, I was driving 60 MPH on the highway and averaged 52 MPG to Lansing and back (130 miles roundtrip). I've only had to fill up 3 times since I've had the car (the first time I didn't record the fuel economy) but I'm averaging 46.1 MPG so far (according to data I've input to Fuelly). I work from home four day per week and then have to commute to Southfield, MI (36.6 miles highway) once per week. My driving is about 30% city, 70% highway.
