Thule Wingbar Evo Efficiency Impact

[Onimaru]

Anyone here test Evo bar impact on battery efficiency? I left my old bars on my gas car year round and never saw a noticeable difference. Curious if people here have measured it. If not, I may do that after I get them and post the results (also want to wait on L2 charger before I do this).

The only way to know the impact is to measure it scientifically. Nobody "sees" impact, but the reality is that putting roof bars on cuts efficiency. Whether you can measure it or not is a different story. 2% is hard to measure.

Bare EVO rack is negligible on mine until I add the SUP or kayak. And I’ve noticed no drop in range when bike is on hitch rack. Thule roof set up comes off in two minutes or less so I leave it off 90% of the time

On and off in a couple of minutes? What’s your set up? Standard EVO with the foot pack?

I have the roof racks and don't believe there is a "significant" difference until something is added on top.

Yup footpack with fit kit for MME. Elected not to go with Edge. And I don’t have glass roof to worry about

I use a Roof rack with a kayak and it probably drops the range 20 to 30 %. Less on regional two lane roads at 80 km per hrs and higher on the highway.
