That is very puzzling. The P85D rated range is 253 mi. and the usual uprating (in my 85) from rated to ideal is about 1.16. That only takes 253 mi to 472 km. An 85D, which is 270 miles rated, would get you to 504 km, which is pretty close. Perhaps "ideal" has been revised upward a bit? But the car is clearly marked as a P85D in the photo?
