Mercedes-Benz AMG GT trim comparison
2025 Mercedes-Benz AMG GT 63 vs 63 S E PERFORMANCE
The AMG GT 63 starts at $179,050 while the 63 S E PERFORMANCE is $195,900. That $16,850 gap buys 6 meaningful differences.
This trim jump changes the engine from 4.0L V8 Turbo to 4.0L V8 phev Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
If you would notice the 4.0L V8 phev Turbo every week, the 63 S E PERFORMANCE makes sense. If not, the 63 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 63 S E PERFORMANCE adds about $297/month on a typical 60-month loan, or around $17,820 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.
