Mercedes-Benz AMG GT trim comparison

2025 Mercedes-Benz AMG GT 43 vs 63 PRO 4MATIC+

The AMG GT 43 starts at $101,100 while the 63 PRO 4MATIC+ is $195,900. That $94,800 gap buys 7 meaningful differences.

The short answer

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 63 PRO 4MATIC+ only when the 4.0L V8 Turbo powertrain is the reason you are moving higher in the lineup.

If you are budgeting this move monthly, the jump from the 43 to the 63 PRO 4MATIC+ is about $1670/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $100,200 more by the time interest is counted. The payment only makes sense if that different powertrain matters to the way you actually drive, tow, or live with the vehicle.
