Earlier,I made a comment that the Tesla Model X could probably pull a 30-foot Airstream with the same power as for the BOREAS XT.
I spent some time analyzing the XT,as per Sighard Hoerner's component drag integration procedure,plus adding in the applicable interference drag.
From BOREAS's data,and the TFLcars road test,the XT will have a frontal area very close to 38.18-sq-ft. From Horner's process,the XT's drag coefficient will come in at around Cd 0.924, for a CdA of 35.278-sq-ft.
Pulling a 30-foot,1976 Airstream Classic,of 7,500-LB,will actually require 'LESS' power than the 9-foot,1,950-LB BOREAS XT.
Despite TFLcars, Tesla owners are routinely pulling trailers across America.The greatest attention must be spent,looking at the particulars of each towing/towed configuration.Context/conditions are everything!
There are more than a half-dozen parameters which must be considered when choosing trailer technology.Any one of them can spoil the party, if left unconsidered.And again,it's what's not mentioned in the TFLcars testing which proves the rule or not.The United States of America desperately needs driver education.
