I stumbled upon the chassis code of the new 2015 WRX and STi while poking around my local dealer's website, and made an interesting discovery. The 2015 WRX and STi no longer share a related chassis code with the standard Impreza. But first, a little history:
Previously, the WRX and STi shared their chassis codes with the standard Impreza model, since they were really standard Imprezas underneath (chassis wise, anyway). This was the case with the GC and GD series.
GC WRX and STi
GC standard Impreza
GD WRX and STi
GD standard Impreza
Starting with the 3rd generation Impreza, the STi (in hatchback form) was graced with a different but related chassis code, GR. The standard Impreza hatchback received the chassis code GH. This was due to the STi moving to a widebody chassis, compared to the standard Impreza hatchback. The WRX hatchback joined the STi on the GR platform in 2011. The GV WRX and STi sedan arrived in 2011, with a different chassis code compared to the standard Impreza sedan (GE).
GR STi (GR WRX, GV WRX, and GV STi are similar)
GH standard Impreza (GE standard Impreza is similar)
Now, that brings us to the 4th generation Impreza, WRX, and STi. The new WRX and STi receive an entirely new chassis code, VA. As far as my research shows, this is the first Subaru to get a V chassis designation. The standard Impreza still carries a G series chassis code, which is GJ for the sedan. This a significant departure from previous generations.
My best guess is Subaru felt that enough significant changes were made to the body and chassis of the new WRX and STi to warrant a new chassis code. I would assume that the changes to the chassis were only as significant as the differences between the GR and GH, and the GV and the GE.
VA WRX STi (VA WRX is similar)
GJ standard Impreza
This would also explain the reports that were going around early on that the new WRX and STi were going to use a different chassis than the standard Impreza. This is actually the case, but it is still a modified Impreza chassis.

What's the Corolla's chassis code again?

Depends one which one. I believe the E160 is the newest one. :P

I wonder if the Evo was any different?
CD/CE/CP/CT9A...

From what I found:
Evo I: CD9A
Evo II: CE9A
Evo III: CE9A
Evo IV: CN9A
Evo V: CP9A
Evo VI: CP9A
Evo VII: CT9A
Evo VIII: CT9A
Evo IX: CT9A
Evo X: CZ4A
It looks like the Evo still has a "C" chassis code. However, I do find it interesting looking at the third and fourth digits (I've only bothered to look at the first two digits for Subaru), that the Evo X is now a 4A instead of a 9A. I wonder if that is related to the fact that the Evo X switched from the 4G engine to the 4B engine?

I knew the WRX/STi changed to VA, but didn’t realize the regular Impreza kept the G first. I wonder what the reason for that was.

Apparently, Subaru felt that the new WRX and STI were different enough from the standard Impreza to warrant a new platform designation. I believe at least some of the reason has to do with the fact that the WRX/Levorg are serving as the effective replacement of the Legacy in the Japanese market. The previous generation Legacy (BM/BR) didn’t sell too well in Japan, mainly because it had become too large of a vehicle. The WRX and Levorg are roughly the same size as earlier Legacys, and seem to be doing a lot better sales wise. The current Impreza and WRX still share a lot of components, but Subaru wanted to differentiate and separate them from each other to maintain their perceived positions in the marketplace. Perhaps the new platform name is part of that separation.

Makes sense
