Took delivery of our Taycan RWD 600 miles from home. Our spec is big battery and 21" wheels. We traveled I95/I75 where 80mph is the norm if you don't want to get run over. Recorded 245-250 miles of range doing the 80mph and ocassional boost to get out of traffic. The 21" wheels and big meat tires are normally a 20% penality on range so I am very satisfied with the highway range of this car. We are seniors and need a break more frequently now. My last BMW g30 5 series had a 500 mile range but I culd never drive that far without a break. The Taycan can skip over 2 chargers and stop at the third which is plenty far enough for us. We have been on long trip along the east coast for years but never drove beyond 300 miles with out a break.
