Porsche 718 Boxster trim comparison
2025 Porsche 718 Boxster S vs Spyder RS
The 718 Boxster S starts at $86,900 while the Spyder RS is $164,200. That $77,300 gap buys 6 meaningful differences.
This trim jump changes the engine from 2.5L flat 4 Turbo to 4.0L flat 6. Everything else is secondary to whether that powertrain difference matters for how you drive.
If you would notice the 4.0L flat 6 every week, the Spyder RS makes sense. If not, the S is the cleaner stop because this jump matters for the powertrain first and the trim badge second.
Think about this as a monthly tradeoff, not just a sticker gap. The Spyder RS adds about $1361/month on a typical 60-month loan, or around $81,660 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.
