More proof that Cadillac might not be shrinking its sedan lineup as planned. 

Comments made at the start of the year by Cadillac CEO Johan de Nysschen pointed to a single model dubbed the CT5 replacing both the ATS and CTS, along with the retirement of the XTS, as the brand looks to reduce its sedan lineup. The plan also called for a smaller, Audi A3 fighter, to potentially join the CT5 and CT6 at some point post-2020. 

In August, GMI discovered clues about the future of Cadillac's two Lansing, Michigan built sedans courtesy of Lisa Graf, a Senior Project Manager at HARMAN International. According to Graf's LinkedIn profile, she was working on the General Motors E2UL, A2SL and A2LL amplifier program. 

The Cadillac ATS and CTS use the platform codes A1SL and A1LL, respectively, the appearance of A2SL and A2LL indicated that the platform derivatives for the ATS and CTS could remain independent after all. 

Recently, more clues surrounding Cadilac's second-generation Alpha platform program surfaced, once again on LinkedIn.

Ken Vallentin, a Program Launch Engineer for GM who responsible for the rollout of the Equinox at CAMI Assembly, in Ingersoll, Ontario, has relocated to Michigan in order to prep the Lansing Grand River Plant for the launch of the A2sL and A2LL programs.  

Vallentin joined GM in February of 2016, seven months before the Equinox was announced, and a year before its market launch in early 2017. It's unclear when Valentin moved to Lansing, but comments left on his profile by Steven Packard, a Senior Manufacturing Engineer at GM, indicate Vallentin completed his duties at CAMI in February of this year. 

If Vallentin moved to Lansing in the early part of 2017 it could indicate the introduction of one of the A2XX pair is imminent. Cadillac has said it plans to introduce one new product every six months from mid-2018 until late 2020 or 2021.
