I just lost my Kona to a deer collision and I'm thinking of replacing it with another Kona or the I5. I pulled my teardrop camper (~600lbs) with the Kona with no problems. It seems the I5 is less efficient since it has a bigger battery with similar range to the Kona. I suspect that towing would result in similar loss of range between the two cars. Is the I5 more capable at towing light trailers?
