An airdam/partial bellypan/skid plate optimized for snow would be an interesting design challenge.
Front air curtains and Moon disks?

Stock tire size is 235/60-16
On my prevous GV i put on 215/70-16 for the studded winter tires. The larger circumference made my speedo show the actual GPS-speed. And the handling was still as expected but a little softer with the more sidewall.
I belive FC was better because of the skinnier tires. About the same as summertime apart from the cold starts which sipped alot of extra fuel.
215mm or skinnier tires like 185-205mm width would be good i think.
In my old car I put 4 extra driving lights on the roof rack above the B-pillar for fun. Thought it would feel as a deployed parachute but i actually did not notice as large drag/resistance as I would have thought. But mostly drove below 100km/h also...
This made me come to the conclusion that the mechanical side was the big culprint to FC and aero did less below 100km/h (60mph)
A bellypan and skid plate would help save the car from rust also. Only positives as i see it. so that would probably be among the first mods. The ladder frame is easy to cover with aluminum or plywood sheats.
If one really streamline the whole car and added a rear box cavity on the boot for a smaller wake, like the attached A2 picture?
Would the proposed aeromods actually be that notisable, you think?
