Mercedes-Benz AMG GT trim comparison
2026 Mercedes-Benz AMG GT 43 vs 63 S E PERFORMANCE
The AMG GT 43 starts at $102,100 while the 63 S E PERFORMANCE is $202,200. That $100,100 gap buys 7 meaningful differences.
This trim jump changes the engine from 3.0L I6 mild-hybrid 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 43 is the cleaner stop because this jump matters for the powertrain first and the trim badge second.
The cleanest way to feel this upgrade is through the payment: about $1763/month more over 60 months, or roughly $105,780 extra all-in once interest is included. 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.
