Another Roof Rack Efficiency Test

This test comes from Kootenay EV Family

The test was performed in 3 different configurations – first Test #1 with a Tesla Roof Rack and a Yakima Ski Box (similar to Rocketbox 11), Test #2 with just the Tesla Roof Rack, and then Test #3 with the stock Model 3 roof (nothing attached, no roof rack).

Overall, the consumption for Test #1 was 207 Wh/km, with just the roof rack coming in at 188 Wh/km, and no roof rack coming in at 185 Wh/km.

The test was performed on a rear wheel drive long range Tesla model 3 with nearly new Nokian Hakkapeliita 9 studded tires.
