The Model 3 owner says that his car gets the same range as if the roof rack is installed without the box if the box is installed with the larger side forward. When the roof box is installed the way it is recommended by the manufacturer (right image above), it reduces the range by about 16%.
He conducted some tests to see how it impacts efficiency, and the results are surprising.įritzson says that the roof rack alone impacts efficiency by about 3.6%. Peter Fritzson, a Tesla Sweden Club member, decided to turn his roof box around at the suggestion of his neighbor who is an aerodynamic performance expert: Now a Tesla Model 3 owner in Sweden has made a simple discovery with his roof-rack box that increases the efficiency quite a bit. Some owners have been testing how a roof rack and a roof-rack box affect the efficiency and range of the Model 3, which is inevitable. The product has been so popular that it has sold out on several occasions.
More than a year later, Tesla finally launched the roof rack as a $450 aftermarket product on its shop website. That said, we knew it was possible since Tesla designed one for the Model S with a glass roof, and a Model 3 prototype was spotted with a roof rack in 2017.
