The new Ascent will pull 5000 pounds, and it's only 37K pretty much loaded. You'll get 400 miles to a tank and you can pick it up tomorrow. Unfortunately the price point just isn't quite there yet for these things to make it worth the extra cash just yet. Electric is still a luxury good, but I'm hopeful for the future.
Yup - base trim pulls less, but the 37K touring ups the towing considerably.
FWIW, I've found CVTs are pretty straightforward for towing things at the right weight while on the road, but admittedly might tow less then a more conventional transmission would get you. I love the gas mileage improvement though. 30+ on the Outback, reliably (highway)
