My ER Lariat gave me a 100% charge range of 310 miles, and then more recently of 299 miles. It varies based on your driving habits and usage history. I typically charge to 85%, and I want to say that gives me a 250 mile range, but I can't recall exactly on that part. As mentioned, it's an estimate to begin with that is based on previous usage data, so your mileage may vary (literally). The weather is getting cooler here in PA where I live, but the truck is garaged, so I'm curious to see how the range is impacted.
