Well, FWIW (prob not much), I asked copilot what GM was going to produce besides the new CT5 at the Lansing plan on the Alpha 2+2 chassis, figuring it would scan through all the news, press releases and leaks better than I could manually:
Quote:
Most Likely Future Alpha‑Platform Models
🥇 Cadillac CT5 Successor (Alpha 2‑2) — Near‑certain
Cadillac has already confirmed the CT5 is continuing with a major refresh and long‑term support.
GM invested heavily in Lansing Grand River to keep Alpha production viable.
The CT5 is Cadillac’s global volume sedan, and its margins justify continued development.
Why it’s almost guaranteed:
It’s already in motion, and Cadillac has no alternative RWD sedan platform ready to replace it.
🥈 High‑Performance CT5‑V Blackwing Successor — Very likely
GM has repeatedly emphasized the Blackwing brand as a halo.
The LT4 V8 is still in production and emissions‑compliant for several more years.
Cadillac’s performance division has hinted at “future enthusiast products.”
Why it’s likely:
GM won’t abandon its most acclaimed performance car while the engine and platform remain viable.
🥉 Cadillac CT4 Successor — Moderately likely
The CT4 sells in smaller numbers, but it fills Cadillac’s entry‑luxury RWD niche.
GM Authority has reported internal discussions about a next‑gen CT4 on Alpha 2‑2.
The platform is already engineered for the size class.
Why it’s not guaranteed:
The compact luxury sedan segment is shrinking, and Cadillac may consolidate around the CT5.
🚗 Possible but Unconfirmed Alpha‑Platform Models
⭐ Cadillac Coupe (based on the “Expressive Coupe” concept) — Plausible
Cadillac has teased a dramatic coupe concept.
Alpha is ideal for a luxury GT‑style coupe.
GM has no coupe in its lineup today, leaving a brand‑identity gap.
Why it’s plausible:
A coupe is low‑volume but high‑prestige, and Alpha is already engineered for it.
⭐ Chevrolet RWD Sedan or Coupe — Possible
Hagerty and GM Authority have both reported that GM is developing “multiple variants” on Alpha 2‑2.
Chevrolet has no RWD car after Camaro’s discontinuation.
A sedan or coupe could revive Chevy’s enthusiast base.
Why it’s uncertain:
Chevrolet’s future is EV‑heavy, and GM may reserve RWD ICE cars for Cadillac only.
🚗 Unlikely Alpha‑Platform Models
❌ Seventh‑Generation Camaro — Very unlikely
GM canceled the Alpha‑based Camaro successor during development.
Chevrolet leadership has shifted toward EV performance instead.
The Camaro nameplate may return, but not on Alpha.
🔍 Summary Table
Model / Concept Likelihood Rationale
CT5 successor Near‑certain Core Cadillac sedan, confirmed continuation
CT5‑V Blackwing successor Very likely Halo product, engine still viable
CT4 successor Moderately likely Fits Alpha, but segment shrinking
Cadillac coupe Plausible Concept teased, Alpha‑friendly
Chevy RWD sedan/coupe Possible Internal reports, but brand direction unclear
7th‑gen Camaro (ICE) Very unlikely Officially cancelled
