I needed to bring my S60 into Lawrence for a new charge port, it wouldn't supercharge at all, and home charge at only 16 amps. Trip was 255km, weather 2-3°C, wet roads, steady drizzle, not sure of wind or wind direction. I don't have tech pkg, so no nav or trip planning software, just my Garmin and trip meter. I charged to 100%, did a couple pre heating cycles, and set off. I still had my winters on, Dunlop winter Maxx, on 19 inch Rial Lugano rims. I turned range mode on, and turned off the HVAC before I left. As soon as I got on the 401 I found a semi with no trailer, but it was just as tall and wide as a trailer, so I settled in about 25 feet behind him. This actually worked out really well, as he was cruising at 105km/hr and without the trailer, his speed never varied at all, even uphill. I figured I would need to stay under 200wh/km to make it, and at the halfway point I was amazed I was running at 169. I then splurged and turned on the HVAC to 20C, and also setting a new trip meter to see how much difference it made. After 10km, I saw no noticeable difference, and ran the HVAC the rest of the trip. With 40km to go I said farewell to my travelling companion, cranked it up to my usual 122km/hr, and still made it with 40km range to spare. I lucked out and got a P85D loaner with AP1, and it was a treat to try AP for an extended drive. Even in the rain, it worked very well, although a few times when passing trucks, it got uncomfortably close to the truck when the pass was almost complete. In traffic and bad weather I found it less stressful to just use the TACC, which worked flawlessly. I was only really comfortable with autosteer in better conditions.
