Cadillac CT5 trim comparison
2026 Cadillac CT5 Premium Luxury vs V
The CT5 Premium Luxury starts at $48,600 while the V is $57,600. That $9,000 gap buys 7 meaningful differences.
This trim jump changes the engine from 2.0L I4 Turbo to 3.0L V6 Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
If you would notice the 3.0L V6 Turbo every week, the V makes sense. If not, the Premium Luxury is the cleaner stop because this jump matters for the powertrain first and the trim badge second.
Think about this as a monthly tradeoff, not just a sticker gap. The V adds about $158/month on a typical 60-month loan, or around $9,480 more overall with interest. 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.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.
