I don't think that is right.
In the research for my upcoming book on car aerodynamic history, I've looked at the percentage cooling drag of the Tesla Model S and the Porsche Taycan.
The Tesla's cooling drag calculates at 8 per cent, and the Taycan's at 16 per cent.
Obviously, these - and other modern cars - can decrease that when cooling isn't needed by closing shutters. But the fact remains that cooling drag on electric cars appears to be similar, or even greater, than on traditional internal combustion engine cars.

Seems like the only reasonable path to a conclusion like this would be a direct, side-by-side comparisons to ICE variants of the Tesla Model S and Porsche Taycan Turbo.
