This is about 9% better, so you could take the current real-world range and increase it by 9% and probably get a decent estimate for the normal driving condition range.
You will not get 560 miles of range out of this vehicle. The typical use is probably closer to your initial worst case guess at around 350-400 miles if I had to guess. Worst case scenario would be even worse than that. The numbers are good, but they're not in a completely different league
