Quick Range Update

Today I drove about 40 miles and got some very odd mileage feedback from the car. I started at a full charge with 90 miles of charge based on the range I was getting on my other drives. I drove the first 15 miles or so on the freeway. I have already learned that freeway driving is much less efficient than city driving. But in the first 15 mile trip, I drove with the air conditioning on slightly and the radio on and lost 20 miles of range on that 15 mile trip. I averaged around 3.9 miles per Kilowatt hour.

On the trip back which covered the same 15 mile freeway drive and an extra 10 miles of city driving, I only lost a couple miles of range. This time I drove with the radio off and the air conditioning on again and used cruise control on the freeway. I averaged well over 5 miles per Kilowatt hour on that drive. Keeping in mind that the battery is a 19 kilowatt hour battery. In all I drove a little over 40 miles and the car is still registering a 60 mile range. That adds to great range that ultimately averaged between 100 and 105 miles for the day.

Therefore, today I have learned that city driving is more efficient than highway driving as the city driving actually added range. And if you do drive on the freeway, my suggestions are to use as few gadgets as possible inside the car such as the radio and air conditioning (either turn it off, keep it on low, or just use the fan which uses much less energy). Also using cruise control and driving slower either at the speed limit or a little below is much more efficient.
