'16 ATS-V MT6 Sedan, Alfas: '67 Duetto, '84 GTV6 3.5L 24v/Vette C5 project
The investment that Caddy/GM put in to the LF4 engine was not recovered with the mere ~4500 ATS-V sales for the ~3 years of production. Given that the CT4 is basically the same ATS dimensions, it makes sense that Caddy would put the LF4 in the hotter version of the CT4-V-Blackwing-whatever. And with the handbuilt nature of the Blackwing TT4.2 V8 and production problems of the CT6-V and Platinums (lower # of engines able to be produced) I can see how Caddy may soldier on with the 2valve Supercharged 6.2L V8 for the hotter CT5-V-Blackwing. Again, return on investment, tweek a few body dimensions on the base platform, add new face, rear-end, and interior (plus new 10sp auto tranny) and call it a day.
