EV Trip Planner shows about 180 RM for an S85 in mild weather and a speed factor of 1.1 (which I find works better than 1.0). A large battery car should make it easily, so it depends on what car one is driving. I'd have trouble doing it in my S60.
One thing to consider is that both the car nav system and route planners seem not to take altitude into account. For speeds of 65 mph or lower I find that they tend to be too conservative for routes at high altitude. I presume that this is because the reduced air density lowers drag significantly. GJ to Poncha Springs in a large battery car ought to be easy, despite the elevation gain, so long as one doesn't go too fast. Also, when east bound, a tailwind is much more likely than a headwind.
