Mercedes-Benz AMG GT trim comparison
2026 Mercedes-Benz AMG GT 63 vs 63 S E PERFORMANCE
The AMG GT 63 starts at $158,350 while the 63 S E PERFORMANCE is $202,200. That $43,850 gap buys 7 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.
Start with the 63 if the 4.0L V8 Turbo already feels sufficient for the way you drive. Step up to the 63 S E PERFORMANCE only when the 4.0L V8 phev Turbo powertrain is the reason you are moving higher in the lineup.
The cleanest way to feel this upgrade is through the payment: about $773/month more over 60 months, or roughly $46,380 extra all-in once interest is included. The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.
