Mine was one of the original ones 55, there is a software revision and some adjustments on battery minimum levels. Apparently there will be a 8-10% range improvement, on one ordered now.
I typically get between 180-220, less when it’s colder or wet, more when it’s sunny and warm done 8,000 miles so far. Only done a couple of long journeys, charging is good and some research is key. Love the car, quiet smooth and quick. Driving it steadily you can eek out more and driving it like you stole it less. If need to know anything else.
