The Breakdown A new report alleges Cadillac will develop a second-generation CT5-V Blackwing. Production for the current-generation CT5 and CT5-V Blackwing ends this year. The car should have a supercharged V8 engine at a minimum, but even that is speculation at this point. If Cadillac is making a new CT5-V Blackwing, it will likely be just as pricey and powerful, if not more so, than the current car.
