Split Bus, Bay, Beetle or any car for that matter......... if you took the windscreen out and removed the tailgate/rear screen would you create less drag?

So........ I was wondering......

Yeah, but that is designed to allow flow to show you wind direction, is it not......? Put a hole in the top of your parachute...... same principle.......
OK..... in theory are you not reducing frontal pressure as well as reducing the 'drag vacuum' at the rear..........?
Can't wait to see you catching flies in your teeth racing a windowless bus.... DHF!
Bonus of adding lightness too

back to the wind sock. It works by catching the air in a big gulp at the front and stopping it from having such an easy exit at the back, thereby SLOWING the wind down by creating drag. I think you'd just be creating a big bloody sail for yourself pat.
also, you'd have all that lovely turbulence and drag inside the van as the wind passes over your interior and tries to pile out the rear screen. Ever see the open topped cars that go on speed trials?
tell ya what, next drag day, you run a flat out pass then come back and kick out your front and rear screens and run again. Let us know how you get on

Yeah, but my bus isn't a sock.
Surely a big hole at the front and a big hole at the rear (as in no tailgate) should let air pass through, no? No interior, just the driver who, potentially could 'streamline' himself over the steering wheel.......

That would surprise me, especially as a bus has a square rear as well creating loads of vacuum..........
Wouldn't that just create more turbulence?
Old beetle has a drag coefficient of 0.38, same as an MX5. 50 years of progress, eh?

I had the Ghia at the strip last year with no windscreen or rear window so I feel well qualified to offer an opinion...
...yes, the car felt less draggy on the trailer and when I pushed it around the carpark...

Get a hairdryer and make a diy wind tunnel ,get yer model van etc.,etc.
Now there's an idea...........!!
Your front window screen is bigger than the rear window so there would be drag similar to the wind sock.
Ok so you've removed your front and rear screens, Fitted a tonneau cover to the inside of the car or van to sweep the air straight through.But would the airflow over the roof and the airflow through the vehicle clash at the rear screen, giving you positive lift at the front therefore making the front of the car light and unstable at speed??
Btw, I have no idea what I'm talking about . It's the wine thats making me type.

Think Pat was thinking of removing the tailgate altogether which should equal size ope
