Porsche 911 trim comparison
2024 Porsche 911 Carrera S vs GT3
The 911 Carrera S starts at $131,300 while the GT3 is $182,900. That $51,600 gap buys 6 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.
Start with the Carrera S if the 3.0L flat 6 Turbo already feels sufficient for the way you drive. Step up to the GT3 only when the 4.0L flat 6 powertrain is the reason you are moving higher in the lineup.
Think about this as a monthly tradeoff, not just a sticker gap. The GT3 adds about $909/month on a typical 60-month loan, or around $54,540 more overall with interest. The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.
