Porsche 911 trim comparison
2025 Porsche 911 Carrera vs GT3 RS
The 911 Carrera starts at $120,100 while the GT3 RS is $241,300. That $121,200 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 if the 3.0L flat 6 Turbo already feels sufficient for the way you drive. Step up to the GT3 RS only when the 4.0L flat 6 powertrain is the reason you are moving higher in the lineup.
The cleanest way to feel this upgrade is through the payment: about $2134/month more over 60 months, or roughly $128,040 extra all-in once interest is included. 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.
