That likely comes from a difference in the trailers. Although this is not EV related, let me cite two examples. Growing up, my parents had a small RV trailer and also a ski boat. The boat on its trailer weighed about 40% more than the RV trailer. Towing the RV trailer had a MASSIVE impact on the gas mileage, whereas towing the boat was hardly noticed. What was the difference? The RV was essentially towing a billboard into the wind, whereas the boat was fairly aerodynamic.

Very oddly, towing a small trailer with an imiev seems to have very little effect. The imiev range is 60-65 miles. When I towed 20+20 miles, I was worried about having sufficient range. But, I got home with about 15 miles remaining. So, the towing cost only about 10%. One way was empty, the other with about 300 pounds of stuff. Trailer is a Harbor Freight type flatbed, about 200 pounds with very low profile. In that test, the load was also very low, lumber stacked less than 1' high. Towing a ~1000 pound teardrop with a Tesla costs 20-30%. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA) _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
