Short trips definitely don't help, and from your months/miles you're putting on about half the miles we have since taking delivery end of July (passed 5K last week, service next Friday). Our work/class commute is a little over a mile, and the engine runs now that it's cold most of the trip to get the system up to temperature, if it ever does. So the engine is running at low efficiency and the batteries/motor don't kick in. Take a long trip and our mileage gets better, close to summer. We're doing about 24-25 compared to about 27 during warmer months where we were short hopping less (walk to work sometimes) and making longer trips to get organic produce (been too busy to enter for a while, keep a running log in the car). Nothing scientific but from reading other boards some actually do better on mileage by extending the drive a little so the engine heats, the battery charges and gets used and the vehicle gets to run without the engine some of the time. Don't have the time to try it though...

As far as starting in stealth mode goes, remember that the HH is a drive by wire vehicle - there aren't the mechanical functions in it that there in a standard ICE vehicle. You can't hit the key on an ICE since it activates the starter that kicks a gear into the flywheel and if it clashes, broken gear teeth (unengineering explanation). There is no starter on the HH, it uses one of the motors that is connected through the CVT the same as the other bigger drive motor and the ICE and the various gears are all designed to be controlled by the computer. I suspect but don't know for sure that the HH knows it's already on and running and simply ignores any more hits on the starter position. While the HH to the driver is just like any other conventional vehicle, the functions are managed by computers and electronics to much greater extent. - John
