Mercedes-Benz C-Class trim comparison
2026 Mercedes-Benz C-Class C 300 4MATIC vs AMG C 63 S E PERFORMANCE
The C-Class C 300 4MATIC starts at $51,650 while the AMG C 63 S E PERFORMANCE is $88,000. That $36,350 gap buys 6 meaningful differences.
This trim jump changes the engine from 2.0L I4 mild-hybrid Turbo to 2.0L I4 phev Turbo. Everything else is secondary to whether that powertrain difference matters for how you drive.
Start with the C 300 4MATIC if the 2.0L I4 mild-hybrid Turbo already feels sufficient for the way you drive. Step up to the AMG C 63 S E PERFORMANCE only when the 2.0L I4 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 $640/month more over 60 months, or roughly $38,400 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.
