I make a lot of short city trips, 1-3 miles. Then park the car for more than a few hours. When I do this, I get mileage of under 20mpg. When I make longer trips (more than 5 minutes), I get 25+ mpg.
This is because it takes a while for an ICE car to warm up, and the initial part of any trip is much more inefficient than after the warm-up. Affecting my observations are other variables (longer trips tend to be more constant, higher speed travel, like highway versus city, etc), but in general ICE cars require a warmup.
Does this apply to the Model S? For example, would ten 3 mile trips separated by three hours in between, result in a much different efficiency than a single 30 mile trip? Assuming the same conditions (speed, stop and go profile, etc).
