The EPA 59mile figure is more of a CYA number. There are several factors involved. One of the biggest ones in wind resistance. The K27 is not a particularly low drag car and it will lose efficiency as it goes up in speed. Remember that when the K27 was initially introduced to the USA there were a bunch of cry-babies complaining that it's top speed of 63 miles could not reach the 65 mph speed limit? So KANDI bent over backwards to accommodate and raised the top speed to 68 mph (which, BTW, you can pump up a notch by swapping the tyres to the next slightly taller ones to eke out 73 to 74 mph). But remember that the faster you go the more wind resistance you must fight through. So, someone I know in Panama as well as somebody I know in China are getting approximately between 75 to 85 miles of range, but they rarely go beyond 55 miles per hour. Why I don't think they even have "Sport Mode" (probably made exclusively for bratty yanks). lol Now, here's a tid-bit, you will get ~105 miles if you avoid "Sport mode" drive it constantly at 37.2 miles on a smooth flat surface when it's not raining if you don;t have the AC or Heat blasting.I don't see how a battery size just over 41kWh can only get 180km of range. I suspect with reasonable driving, it can get well over 200km. But we will have to see real world operation to know for sure.
One saving grace will be the speed at which it will charge once it is equipped with a speed charger. KANDI has said that they intend to provide that, but not sure if it will be on their first year of sales or on the subsequent one. And if they don't I don't know if they will make this option available to those who had already purchased their vehicles for free. (I would hope) But I mostly hope that they'd offer it fro the get go. Envision filling up your battery in only 10 minutes! That makes things an whole lot more doable. Now you can reach farther places and not have to carry around an auxiliary generator to mitigate anxiety. Also, Biden seems to be promising to multiply the number of available chargers, because there is now a scarcity of them.
Also, I don't know if you are or not an experimenter, but the person I knew in China was an electromechanic and he'd taken his car to the body shop to install some solar panels which ended up yielding him up to 12 miles per day. He'd begun by installing a roof rack with a 200W panel on top, but not only did that look ridiculous it also was not terribly efficient at high speeds due to the drag, which is why he had it professionally installed smoothly at a body shop. I knew him from my previous job unfortunately and have lost touch with him. He was already an electromechanic by trade. Enjoy!
