I've been watching a Japanese man who hypermiles the Chevy Bolt. Hypermiling means using certain practices to obtain maximum range. He's able to go approximately 400 miles on a single charge.

To get this astonishing range requires three conditions; flat roads, a cool climate and no rain. Low on charge, a hill may kill the battery before regeneration can occur, there's no need for HVAC and battery conditioning in a cool climate and rain causes drag on the car.

All driving including highway driving is done at 25 mph. This is obviously a stunt, but what is interesting is the tension that occurs when he's trying to get the last mile out of the battery. Guess wrong and be stranded.

Electric car makers, in order to extend battery life, allow about 60% of the car's battery capacity to be used. If I owned a Bolt I'd want a switch that makes that other 40% available even if using that switch invalided the battery warranty. I suggest invalidating the battery warranty is better than being stuck some place in the middle of the night where you don't want to be. What do you think?

I usually try to see if I can get a full tank of E85 to last <100 miles....lol.

I was able to get an indicated 36.3 mpg with V6 Manual Honda accord coupe. Trip was about 35 miles in length. This could only be achieved by coasting out of gear, off throttle, whenever possible.

Driving more normally, with a constant but light throttle, the best I could get for that same route was about 32 mpg.

I think ruining the battery warranty just to get a little more is not a good idea. A tow is a lot cheaper than the potential costs of a new battery if you ever have issues. And it's a GM, so you want to hang on to that warranty for as long as you can

I got 4mpg at Watkins Glen for about 2 hours of driving.
I am not sure how many dinosaurs that took, but I thank them for dying and rotting.

I'm pretty sure this wouldn't qualify as hypermiling.
