Porsche 911 trim comparison
2025 Porsche 911 Carrera S vs GT3
The 911 Carrera S starts at $159,600 while the GT3 is $222,500. That $62,900 gap buys 5 meaningful differences.
This trim jump changes the engine from 3.0L flat 6 Turbo to 4.0L flat 6. Everything else is secondary to whether that powertrain difference matters for how you drive.
If you would notice the 4.0L flat 6 every week, the GT3 makes sense. If not, the Carrera S is the cleaner stop because this jump matters for the powertrain first and the trim badge second.
If you are budgeting this move monthly, the jump from the Carrera S to the GT3 is about $1108/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $66,480 more by the time interest is counted. 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.
