Cadillac CT4 trim comparison
2026 Cadillac CT4 Sport vs V Blackwing
The CT4 Sport starts at $43,800 while the V Blackwing is $62,700. That $18,900 gap buys 7 meaningful differences.
This trim jump changes the engine from 2.0L I4 Turbo to 3.6L V6 Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
If you would notice the 3.6L V6 Turbo every week, the V Blackwing makes sense. If not, the Sport is the cleaner stop because this jump matters for the powertrain first and the trim badge second.
The cleanest way to feel this upgrade is through the payment: about $333/month more over 60 months, or roughly $19,980 extra all-in once interest is included. If that different powertrain is not part of your real use case, the cheaper trim keeps more money in your pocket without changing the core experience you need.
