I own a Polestar 2 with an effective 75 kWh battery and an average efficiency of 3.3 mi / kWh. So 248 mile range if you charge to 100% and run it down to 0%. Real world, 99.9% of driving I do is well under 100 miles per day, and my charging between 6pm and 8am on a 120V outlet adds 50-60 miles. You could plug in every night, but in practice I wait until the battery is below 40%, and tend to plug in every 1-2 weeks depending on how much I use it. It's been driven over 200 miles in a single day twice, and each time the car was charged for 15-20 minutes at a fast charger to top up. shrug For many people, in real world usage, 205 mile range is great for how you'll actually use the truck.

> average efficiency of 3.3 mi / kWh. I'm curious, is that your personal average or is that what the company claims? I've not taken the plunge on an EV yet, but realistically I'm interested in the actual range driving 70-75mph on the highway, with the AC running, as compared to the manufacturer's claims.

  A good rule of thumb across most makes is to take the EPA range number and multiply by 0.85, and that’s what you’ll get at a constant 70-75 mph in moderate weather (say, 55-85 degrees) with the climate control on. Of course, you probably want to arrive at your next charge stop with 5-10%, and the top 10% of the battery charges very slowly in all EVs, so you normally multiply by another 0.80 factor to take that into account.

  Probably worth noting that Polestar 2s are not particularly efficient, though lovely to drive. Mine averages about 3.2mi/kWh for most trips, though there are lots of EVs out there getting 4+ miles/kWh.

  That's my personal... to get the 260 mile advertised range on 75 kWh battery, it would have to average 3.47 mi / kWh. I sometimes get over 4... but I also often get under 3 (especially in winter, when 2.5 is common.) Highway at those speeds in the summer (with AC) is ~3 or so which gives you ~225 effective road trip range between fill-ups.
