Impala, Lacrosse and Cadillac XTS were built on a long wheelbase variation of the Epsilon platform. I remember that the XTS program code was P1LL. Easy for me to remember because it spells pill and i used to refer to it as the pill. I can’t remember if Impala was P1LC or E1LC. Technically, either could have worked. I’m pretty sure Lacrosse was E2LB. Regal was E2SB.

If I correctly understand, Epsilon II and E2XX are one and the same?
This states that the Epsilon II precedes the E2XX:

When you say the XTS program code was P1LL, is that different than the platform?
Since the Impala, Lacrosse and XTS were built on the long wheelbase variation of the Epsilon platform, doesn't it mean they were on the P2XX platform and not the E2XX platform?
This only lists the 2017-18 Impala and not prior years:

But then there's this platform information:

It's all over the place!
@Martinjlm I'll wait for your response, because it's driving me insane.
