Since it's a hybrid with automatic grille shutters, there is no opportunity for adding an air dam, grille block, alternator kill switch, or engine kill switch. I plan to drive it as is through summer to get a base line, then add an aero topper Fall 2022.

On a recent cold start at 0 deg F, I backed out of the garage, and checked the trip mileage at 0.25 miles. The trip mileage at that check point was 6.6 MPG, worse than my old Canyon which would have got 9 MPG at the same point and under the same conditions. When everything is warm, that same route can be done electrically. The engine ran continuously, even with foot completely off the gas pedal, for two miles before shutting off. After that, it cycled on and off normally.

The hybrid engine is programmed to keep running until the battery is warm enough to take a charge and until warm enough to get useful heat out of the heater. This suggests an opportunity for significant mileage improvement on cold weather short trips by preheating both the engine and the high voltage battery.

At my normal speed in a 55 limit of 57 MPH and at 10% power on the power meter, the instantaneous mileage varied from 25 to 40 MPG apparently depending on the state of charge in the high voltage battery. This also explains the poor mileage at the start of a trip after a cold start. It suggests an opportunity to improve mileage on shorter trips by charging the high voltage battery to 100% charge when parked. The last three miles of a typical trip home are almost all on the electric motor, so I typically leave home with a low charge in the high voltage battery.

I have no plans to do either the preheating or high voltage battery charging at this time.

Do you wish you added the engine block heater? That would cut your heat time down.
