Porsche 911 trim comparison
2025 Porsche 911 Carrera 4 GTS vs GT3
The 911 Carrera 4 GTS starts at $186,000 while the GT3 is $222,500. That $36,500 gap buys 6 meaningful differences.
This is a powertrain and drivetrain change. The GT3 gets the 4.0L flat 6 and RWD, so the $36,500 is buying a different driving experience, not just nicer trim.
Choose the Carrera 4 GTS if the 3.6L flat 6 hybrid Turbo with AWD already covers the way you drive. Move to the GT3 only when the 4.0L flat 6 and RWD combo is the reason you are shopping higher, because that is the real hardware split here.
The cleanest way to feel this upgrade is through the payment: about $643/month more over 60 months, or roughly $38,580 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.
