My commute is 65 miles round trip with 12 miles each way on the Palisades Interstate Parkway.
On the way home while on the Palisades I switch to Hold Mode to run the engine, switching back to Normal when I take my exit. At that point I have a dozen miles left in the battery, more than enough to get me home.
As I switch to Normal I bring up the info screen and it will tell me that I got 40 some MPG (gas).
For the rest of my trip the engine will not kick in BUT the MPG number will change often indicating 65 MPG by the time I am home.
What is going on? Why does the MPG figure change with the engine off?
