Base pressure variation, on both Insight and Mercedes--is it uniform or variable based on location? Does the base pressure fluctuate with time or is it steady?
Yes, I thought I'd use an array of all 16 sensors in the base area and log at the highest speed I can. My expectation is that (a) the pressures will vary depending on location, and (b) they will be quite unsteady as vortices are shed.
Pressure change on the Mercedes' roof with a spoiler (after seeing what happened on a fastback, I'm curious what a notchback does)
Pressure change under the Mercedes with a spoiler
I thought I use all 16 sensors along the car centreline top and bottom and trial various mods, including a rear spoiler, front air dam and full undertray.
Pressure change on the boot lid and backlight with vortex generators along the roof edge (I don't think I've ever seen this measured aside from the Mitsubishi paper and they didn't show data without their wing)
Great idea. I'd also tuft test the Mercedes - something I've not done with this car.
