Mercedes-Benz AMG GT trim comparison

2025 Mercedes-Benz AMG GT 53 vs 55

The AMG GT 53 starts at $112,000 while the 55 is $137,550. That $25,550 gap buys 7 meaningful differences.

The short answer

This trim jump changes the engine from 3.0L I6 mild-hybrid to 4.0L V8 Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.

Start with the 53 if the 3.0L I6 mild-hybrid 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.

The cleanest way to feel this upgrade is through the payment: about $450/month more over 60 months, or roughly $27,000 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.
