Porsche 911 trim comparison
2024 Porsche 911 Carrera 4 GTS vs GT3 RS
The 911 Carrera 4 GTS starts at $158,200 while the GT3 RS is $241,300. That $83,100 gap buys 8 meaningful differences.
This is a powertrain and drivetrain change. The GT3 RS gets the 4.0L flat 6 and RWD, so the $83,100 is buying a different driving experience, not just nicer trim.
This is a real hardware fork, not just a trim-label shuffle. The Carrera 4 GTS is enough if the 3.0L flat 6 Turbo with AWD already fits your routine; the GT3 RS only earns the jump when the 4.0L flat 6 and RWD setup is the point of the upgrade.
Think about this as a monthly tradeoff, not just a sticker gap. The GT3 RS adds about $1463/month on a typical 60-month loan, or around $87,780 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.
