Morning,
I'm running a 2016 SV with a 65 mile per day commute in northern Vermont, USA.
I have two options for route. An Interstate and a state road. The state road speed limit is 50 mph and the Interstate is 65 mph.
I've been swapping between both roads at different temperatures to see which is more efficient.
The obvious answer you would think I'd the slower road.
I'm find this is not always the case. In the summer yes. Driving the slower road leaves me with more charge left when I return home than drive into the faster road.
However now that it's colder, they are almost the same. Speeds being 60 mph on the interstate and 45-50 on the state road.
The State road takes more time. I am wondering if that longer time running heat is drawing enough battery to negate the savings from driving slower.
The miles per kWh readings are within a few points difference so that backs up that theory.
It seems when it is colder, single digits F, the difference is reduced.
It seems the cars range in single digit weather is about 80 miles regardless of speed. Not exceeding the speed limits in these cases. I do reduce the heat use to minimal fan speed, 65F temp setting, and set the recirculate to partial. I work outside so I'm dressed for cold anyway. With the heated seat an occasionally turning on the steering wheel heat I'm quite comfortable. I do notice that when leaving the climate control set on auto the system uses a lot more power. That setting keeps the fan on a fast speed.
Any have thoughts on this?
This is my first winter with a BEV so I'm still learning.
Thanks and have a great holiday.
