My dual motor performance Model 3 is supposed to have a 325 mile range (+/-). When I charge to 80% it registers about about 277 miles when charging stops. I've driven the car in the summer. I've driven the car in the winter. I've driven city and I've taken road trips. Regardless of the temp outside OR the type of driving I do, I don't get ANYWHERE NEAR the advertised miles (like, not even close). Did Tesla find a 325 mile downhill slope somewhere to test mileage? I've owned the car just under a year and have put about 10,000 miles on it. Anyone else have this issue?
