Mercedes-Benz AMG GT trim comparison
2024 Mercedes-Benz AMG GT 43 vs 55
The AMG GT 43 starts at $98,950 while the 55 is $134,900. That $35,950 gap buys 6 meaningful differences.
This trim jump changes the engine from 3.0L I6 mild-hybrid Turbo to 4.0L V8 Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the 43 if the 3.0L I6 mild-hybrid Turbo already feels sufficient for the way you drive. Step up to the 55 only when the 4.0L V8 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 55 adds about $634/month on a typical 60-month loan, or around $38,040 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.
