OK - FIRST LEG TRIP UPDATE
I pulled into Windsor Comfort Inn (Ambassador Bridge) about an hour ago...and lucky I did - I pulled in with 0 KM remaining on the car!
I started off at home with a full charge for my drive to Toronto. We had a visit at the Hospital for Sick Children for my son's weekly infusion so I parked at the Yorkdale Mall in the Tesla underground parking, plugged the car in, and headed downtown on the subway. The underground garage is closed until 9:30 AM, but we just told them we were heading down to Tesla to charge for a while and they let us in with no issues (we were quite thankful, as it was only 8:45 am).
I returned in the afternoon to a full charge (434 rated KM) for my journey to Windsor. I took the advice given here and limited my speed and drafted trucks where I could. I didn't put Range Mode on until the end of the trip (I never see much difference with it on or off), and kept the heat at about 20 degrees. I found a following buddy (large transport - with a TRI-CORP logo on it, a red GREAT DANE badge, truck number TRI759 - I had to stare at it a long time! I memorized the license plate as well, in case you're wondering
)
About halfway though my trip, things were going very well. Rated Range and Projected Range all had me making it to Windsor with about 35 KM to spare. But then the storm hit - high winds, icy roads, snow, slushy portions on the 401. And did I mention a decent headwind? Rated Range and Projected Range dropped quickly and I started to get nervous.
I lost my driving buddy - they were driving faster than I wanted to, given the conditions - so I was on my own. Luckily, the speed of traffic dropped significantly, so I was able to comfortably draft a few trucks going 87-90 km per hour, then all the way down to 65 km/h for the last 50 KM. That helped my range considerably. Temperature outside was -4 (-10 with Windchill)
Even with range mode off, the cabin got a bit cold due to the draft coming in my triangular window (a long and frustrating story from Tesla Service in Mississauga that is being rectified - again). The higher winds made the cold draft come in a lot. I was able to drive with Range Mode off for most of the trip, I put it on with 10km rated range to go because I got a bit nervous ;-)
My last 50 KM, I showed 50 KM rated range, and 50 KM projected range. I was starting to worry, and hoping that the hotel had set aside the charge spot for me (I called ahead to request it). With 0 km showing (probably -3km range because it said CHARGE NOW for a few KM after 0), I rolled into the hotel to see my spot blocked off and ready for me. She's outside charging up now, I'm inside warming up. A great start to my adventure, and only slightly stressful.
If I were to do it again, I would forgo the adventurous part of the trip and drop into Chatham for 1/2 hour or so charge. It donned on me that I'd be in trouble if there were an accident/traffic jam up ahead, or that I would be in trouble if something were to happen to me in my car. I'll play it safer next time, for sure. But - I made it!
Was so nice to be driving an Electric Vehicle. On the way, I was listening to the Toronto News about high Cancer-Causing toxins in the air near an Etobicoke community - caused by high emissions from the 401/427 corridor nearby. Was happy to be doing my bit to take those emissions out of the equation.
On my way to Chicago area tomorrow. Will update when I can. Thanks again to everyone for the help and planning along the way!
