1.5 miles per KWh in real world high speed, highway use. The only way to get 2 miles per KWh is to go slow. But with speed limits at 75 and even 80mph in places, and even one stretch of 85mph, and common speeds around 80 on most interstates, the real world has a way of eating up battery power.
Mostly unrelated to the debate in here, one thing in your post caught my eye. Speed Limits *LOL*
There are no speed limits!! Except maybe some parts of Georgia.
I drove from SC to Florida (as you may know) I think 7 (seven) times in early summer. I was blown away how fast everything was moving, even semi's, sure, I got used to doing 80 in a 70 and I really try not to exceed it ... but driving from I-26 and throughout I-95 if you dare drive at 75 to 77 MPH you will risk getting rear ended *LOL* I am NOT kidding.
Even doing 80 MPH cars will zip by you at 90 and you feel like your in the slow lane at 80 if behind a car in the right lane (and dangerous) and over time, it seems I might have been passing some vehicles looking at the speedometer and seeing 95 MPH. Maybe it was the time of year of no law enforcement?
Ive never been so impressed with an SUV as this Traverse, 5000 lb tow limit and at those speeds I got 20MPG which is higher than the 16 to 17 around town (wasnt towing). Super quiet even with the optional 20 inch wheels, no rattles which seems amazing for a GM. Its really exceeded our expectations, the only criteria when we bought this was a factory tow package, it didnt have to be any particular brand.
SO they have to figure out the battery thing or h2 .. around town EV's sure, no problem, people who enjoy the wide open roads this country offers like almost no other place on earth, give me fossil fuel or h2
Gotta be careful in Georgia though and REALLY careful by the GA FL border.. wow... amazing difference, they actually enforce the law and I have no problem with that but in most all other areas, if you try to do those 70 to 75 MPH numbers in an EV, be prepared to put you life in danger from everything, including tractor trailers.
