How does one tell the difference between RC and Alpha? The most obvious one I can think of is the AP2 camera in the side Tesla badge that makes it bulge out. The picture doesn't have that so it's most likely the Alpha.
Yeah, that is the first place I look... The side T-logo repeater light triangle to see if there is a camera there (RC) or not (Alpha).
For now, you can tell the Alphas by their red brake calipers too. Those might show up on production versions once they start building performance versions.
