So what is the estimated Cd?
There is a reason that Tesla didn't give this number in the reveal. Past reveals bragged about the amazing Cd.

So what is the estimated Cd?
An airfoil has something like a 0.045Cd, an airfoil is like a plane wing. Aero is more about how you release the air than how you hit it.
The very long slope and bed cover do help and you can see that it starts just above the driver's head, that's not random.
With this vehicle, the air goes mostly over and under it. The flat underbelly should help. The pointy top, hard to say but does seem like it risks separation and hard to guess if they do anything to mitigate. Maybe they also factor in situations where the bed is not covered or the vehicle is towing something and they want to address those too. Sharp corners do make for a clean separation, it's not always a bad thing. Would be silly to try to guess Cd but trucks are not great in this area and Tesla likely does a lot better.
My guess is that they get 3 EPA miles per kWh so 100kWh pack for the 50k$ version and somewhat twice that for the 70k version.
No one expects it to match the cars, but for a truck it will be very good. Also they already packed a lot of information into the presentation, too much info tends to be counterproductive. No doubt they will do some followups closer to the release date.There is a reason that Tesla didn't give this number in the reveal. Past reveals bragged about the amazing Cd.

For the same cross-sectional area, yes. But the truck is taller than the X. The ratios look similar to me (15% longer and taller).I actually think the Cd might be as good as the cars or even a little better.
Longer shapes usually have less drag,
The gradual rear taper is a big win, no doubt.and that long rear deck lets you dump half the cross section in a very smooth even way.
I'd need a lot of convincing on this.The air dam up front appears to be pretty effective in blanking the front wheel wells
Even in the production version?and there aren’t any mirrors
Even in the production version?
Elon Musk on TwitterWith extreme effort, Cybertruck might hit a 0.30 drag coefficient, which would be insane for a truck. Requires tweaking many small details
So much for the armchair engineers.
Yup, put the CT into a wind tunnel and compare to the F-Xxx trucks.
I fail to see the scientific validity of hand drawings with color shading, and/or the cd listings of shapes, as being supportive for the OP's debate. Our order is to replace an F250 PSD with this CT electric torque monster. We're not Tesla fanboys or girls, or eco-warrior greenies, but we probably WILL be now.....
Once you take delivery, find a cop with a radar gun. Tell the cop to park to switch on the radar and keep it running continuously. On a long, flat, straight and empty road, approach the radar gun. Have the cop flash his lights when he "acquires" the CT. Then note the distance from the acquisition point to the radar gun. Back when I was in the radar jamming biz, a half mile was the common distance of acquisition. If you can get closer than that, congratulations. A good radar detector will pick up the radar signal well before the gun can pick you up. I could tell you some really comical stories about what we did with police radar guns.
No need. the F117 had radar absorbing paint and other counter measures for radar. It had the radar silhouette of a small bird.Once you take delivery, find a cop with a radar gun.
