Kayak aerodynamics impact of Wh/mile

[YYZ-IAD]

Hi

Off topic for most of you - but it does show to importance of aerodynamic drag - or lack thereof.

I have official Tesla roof rack installed. Without ability to do controlled experiment for temp and route - I think loss of efficiency from rack alone is negligible.

This weekend I had 2 kayaks mounted up top of the MS. Consumption was consistently in range of 380 Wh/mile @ 60 mph. Standard for me at that speed is about 280.

Demonstrates that Tesla's effort to produce "slippery" cars with low drag is well warranted.

Interesting, thank you

Aerodynamics really kick into gear at about 50+ MPH.

I wonder what the effects would be driving with kayaks at 50 as compared to 60.. ?
Or maybe try to find the speed you need to drive to achieve 280 Wh/mile. ?

If you want to complete the experiment.
