Mercedes-Benz AMG GT trim comparison
2024 Mercedes-Benz AMG GT 55 vs 63 S E PERFORMANCE
The AMG GT 55 starts at $134,900 while the 63 S E PERFORMANCE is $194,900. That $60,000 gap buys 5 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 55 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.
Think about this as a monthly tradeoff, not just a sticker gap. The 63 S E PERFORMANCE adds about $1056/month on a typical 60-month loan, or around $63,360 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.
Lock one trim, change the other side, and move through exact pair pages without resetting back to the full lineup every time.
