Impact/EV-1:a forensic reconstruction

[cfg83]

Hello -

I just ordered a brochure from ebay that is just like this one :

GM/GENERAL MOTORS EV1 ELECTRIC Car SPEC SHEET/Brochure - eBay (item 200382445863 end time Mar-08-10 15:14:14 PST)

When it arrives, I will scan the side/front/back/top views and post them.

Hello -

Here are the pictures I wanted to post, but the item hadn't arrived yet :



I guess that the "rear wheel" shadow means that this picture probably has some perspective in it, .



The vertical lines in the pictures are the fold-out crease.

Too bad the top is a different scale than the front and back. Notice that the mirror supports are kind of "buried" in the rear view, so yes, there is a little perspective distortion.

I totally missed that. Thanks. Back in post #20 you can see the same thing. I'll bet they came from the same source.

At 4-locations,moving back along the template,for 10,20,30,and 40% aft-body,I measured 9,20,19,and 15-degrees,respectively.
With the racing boat tail,the terminus angle is 11-degrees.
If you lay a straight-edge across the back of the boat tail and up over the backlight,it measures 16-degrees.

Also, in the low angle pictures I've seen, you can see the rear wheels from the front because the rear track was quite a bit narrower than the front.

Is it just me, or is the "Impact" (prototype of the EV-1) a much better looking car?


The nose is obviously different, and I detect a deeper contour in the doors and a slightly "hunched" rear fender -- anything else different that you can see? Was the Cd different?

Maybe it is tapered from the sides? That is, instead of looking at airflow from the side of the car, look at it from the top.
