My wife is about to take our first long trip in the Tesla to go to a meeting in Houston. Return trip is not an issue since she has plenty of places to stop off if it range gets hairy (spring, huntsville, corsicana). But on the trip down she would like to minimize supercharger to arrive quicker. Since neither of us have done longer highway cruising driving we are unsure of the range.
We have a 2013 S85 w/ 19in wheels (but the regular tires, not primacy). I have calculated range loss to be around 4% (which is a max range of 255 - but I haven't full charged this is just an estimation off the 90% which varies around 230-234).
We live south of DFW in midlothian and the hard miles to the huntsville supercharger is 162 miles. Is that doable? My previous car was a Leaf so highway driving tanked the range much much more so I have a harder time predicting the Model S's range. I tried EV trip planner and the range was at the make/break point leaving 15% battery as a buffer depending on the speed of the headwind (above 15 mph it said it wouldn't make it). That accounts for ~36% loss of range from the rated. Is it really this much or is the trip planner being ultra conservative? Tesla's range calculator on the 70D (closest in rated miles to the S85) shows a full crusing range @ 70 mph and 90 degree weather with AC and 19" wheels at 238 miles of total range. So these two calculations vary considerably.
I just didn't have any experience otherwise to fall back on. Yes she could stop in corsicana, but if there is not any needed she would like to not waste that 20-30 minutes or so.
