My wife drives 125 miles each way to work 4 days a week. Max range at 100% on our LR is 325 but we also have the 19” wheels which does reduce the range by 10% or so.
At 100% charge and driving between 75-85mph all the way (100 miles are highway) she can just about make it there and back with no charging, but it’s tight. She normally stops off on the way back for 10 minutes at the supercharger (soon to be upgraded from 300mph to 600mph) which gives her 50 miles (100 after upgrade), and time to grab a drink. She will be charging at work soon, so that will completely alleviate that need. If she drove at 70mph the entire way, I have no doubt 280-300 miles would be the true range.
End result is $500 a month saved in petrol, and a much more relaxing commute with the autopilot.
