Mercedes-Benz CLA trim comparison
2026 Mercedes-Benz CLA CLA 250 vs AMG CLA 45 S
The CLA CLA 250 starts at $42,750 while the AMG CLA 45 S is $67,550. That $24,800 gap buys 7 meaningful differences.
This is a powertrain and drivetrain change. The AMG CLA 45 S gets the 2.0L I4 Turbo and AWD, so the $24,800 is buying a different driving experience, not just nicer trim.
Choose the CLA 250 if the 2.0L I4 mild-hybrid Turbo with FWD already covers the way you drive. Move to the AMG CLA 45 S only when the 2.0L I4 Turbo and AWD combo is the reason you are shopping higher, because that is the real hardware split here.
If you are budgeting this move monthly, the jump from the CLA 250 to the AMG CLA 45 S is about $437/month on a 60-month loan at 6.5% APR with 10% down. That works out to roughly $26,220 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.
