Porsche 911 trim comparison
2026 Porsche 911 Turbo S vs GT3 90 F.A. Porsche
The 911 Turbo S starts at $270,300 while the GT3 90 F.A. Porsche is $387,000. That $116,700 gap buys 5 meaningful differences.
This is a powertrain and drivetrain change. The GT3 90 F.A. Porsche gets the 4.0L flat 6 and RWD, so the $116,700 is buying a different driving experience, not just nicer trim.
Choose the Turbo S if the 3.6L flat 6 hybrid Turbo with AWD already covers the way you drive. Move to the GT3 90 F.A. Porsche 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.
Think about this as a monthly tradeoff, not just a sticker gap. The GT3 90 F.A. Porsche adds about $2055/month on a typical 60-month loan, or around $123,300 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.
