Reply to comment by bigflamingtaco in A breakthrough in electric vehicle battery design has enabled a 10-minute charge time for a typical EV battery. The record-breaking combination of a shorter charge time and more energy acquired for longer travel range was announced today by Wagamaga

With the extended range battery it's almost 3 hours towing

Towing... a utility trailer with a lawnmower in it?

Check out TFL's tests on YouTube. You aren't getting 3hrs of towing on the extended battery with anything but a small trailer. Their larger trailer cut it to 150 miles. If you're dragging a travel trailer through the wind, will probably see 100-120 miles.

I read a review by insideev's where they towed a campervan, that's where the number came from, that may be better aerodynamically though, apparently weight is not such an issue, but simply enclosing a trailer then would give enourmous range benefits

If you can find that, I'd appreciate a link, didn't see anything on their website.

Geeky Schmidt towed a small Airstream camper, and it cut his range in half. Unfortunately, that's not the typical camper as those things are ridiculously expensive, and they also sit low to the ground, which limits where you can go with them.

I average 20mpg unloaded, 10mpg with a 7ft wide cargo trailer. Although I wouldn't tow a camper at 70mph like in the above situations, a typical hard side camper is 8-8.5ft wide and sits about two feet higher at the roof. At 60 mph, it's also going to cut the range in half, or worse, depending on the trailers actual dimensions and amount of junk attached to the exterior.

Camp-inn did an aero study of their teardrops and found their trailer that curves at the corner side walls in the front cuts through air better than the traditional teardrop style of cutting at the top and bottom. Probably has to do with how the air becomes turbulent exiting the sides of the vehicle's. Would like to see more mfg's try alternate designs for better aero, including stuff like lower skirts and those things the truckers put on the rear of their trailers.
