Porsche 911 trim comparison
2025 Porsche 911 Turbo S vs GT3 RS
The 911 Turbo S starts at $230,400 while the GT3 RS is $241,300. That $10,900 gap buys 7 meaningful differences.
This is a powertrain and drivetrain change. The GT3 RS gets the 4.0L flat 6 and RWD, so the $10,900 is buying a different driving experience, not just nicer trim.
This is a real hardware fork, not just a trim-label shuffle. The Turbo S is enough if the 3.7L 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 $192/month on a typical 60-month loan, or around $11,520 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.
