upper pressure profile

Seems like an earlier pre-fascia car, with a jutting front bumper, nerf-bars, and very long bonnet, which narrows it down to something akin to an XKE Jaguar Coupe.

If I could post new pics I'd have better subjects.

Open top car?

Not a bad guess, but incorrect.

For people struggling with the front pressures, to my eyes the whole graph looks exaggerated vertically - that is, the pressure variations are all greater than I would have expected based on my own measurements on other cars.

So maybe when picturing the car, dial back the pressure variations (but not whether they're positive or negative) a bit.

Having said that, people are doing a pretty good job so far.

Oops, I just realized positive pressure was below the x-axis. My mind always defaults to a positive value being represented higher on the chart. My ability to visualize would be helped by flipping it.

Why can't you post pics? I use https://postimages.org/

And no, it's definitely not an open top car.

The better question is why I think I could do better.

Mostly it's a mental block. The last copy I bought, 2nd hand, of Photoshop doesn't work on my current system. I've tried Krita and some others but nothing clicks. My best bet is likely Greasepaint inside Blender, but that's where the mental block comes in. I've beat my head against the learning curve in 3D, so I'm leery of taking on the 2D side. Or the video compositing.

So Mercedes Benz SSK mit kompressor?
